Abstract
Objectives. The aim of this study was to assess factors affecting the efficacy of three months of physiotherapy carried out in nursing home (NH) conditions.
Material and Methods. The study involved 71 patients undergoing rehabilitation in a NH. The mean age was 77.4
(± 7.3) years; 81.7% were women; 25.4% had had orthopedic injuries; 56.3% had had a stroke; and 18.3% were
patients with chronic diseases. The Mini Mental State Examination (MMSE) was used to test the patients’ state of
cognitive function. The Geriatric Depression Scale (GDS-15) was used to determine their mood, and the Barthel
Index (BI) was used to assess their functional status. The efficacy of physiotherapy (EP) was specified after each
month of physiotherapy (EP1, EP2, EP3).
Results. Cognitive impairments (MMSE < 24) were found in 73% of the patients, and symptoms of depression
(GDS > 5) in 65% of the patients. The average BI score upon admission to the facility was 38.6 (± 20.2), and after
three months it was 59.2 (± 24.5) (p < 0.00001). The average EP3 was 20.6 (± 15.0). In the case of 31% of the patients,
EP3 was very low: 4.8 (± 3.6). A significant relationship was revealed between EP3 and MMSE (p = 0.00113), EP3
and GDS (p = 0.01223), EP3 and diagnosis (p = 0.0106) as well as EP3 and EP1 (p < 0.00001).
Conclusions. An increased risk of physiotherapy failure in NH conditions was observed in patients with profound
cognitive impairments (MMSE < 11) and severe depressive symptoms (GDS > 10). The strongest rehabilitation
progress in the NH was observed among patients undergoing rehabilitation due to orthopedic injuries. The best
and the most precise prognostic factor for the outcome of physiotherapy after a three-month NH stay is the effectiveness of physiotherapy after one month of hospitalization. A lack of an improvement in functional status after
the first month of rehabilitation could indicate a need for the standard model of rehabilitation to be modified, or
for the patient to be transferred to a specialized rehabilitation unit (Adv Clin Exp Med 2010, 19, 6, 755–764).
Key words: elderly patients, efficacy of physiotherapy, long-term care unit.
Streszczenie
Cel pracy. Ocena czynników wpływających na skuteczności 3-miesięcznej fizjoterapii prowadzonej w warunkach HN.
Materiał i metody. Badania przeprowadzono w zakładzie opiekuńczo-leczniczym (NH). Do badań włączono 71
osób: średnia wieku wynosiła 77,4 (± 7,3) lat; 81,7% stanowiły kobiety, 25,4% to osoby po urazach ortopedycznych, 56,3% pacjenci po przebytym udarze mózgu, a 18,3% seniorzy usprawniani z powodu chorób przewlekłych
wieku podeszłego. Badano stan funkcji poznawczych i nastrój za pomocą Mini Mental State Examination (MMSE)
i Geriatric Depression Scale (GDS-15) oraz stan funkcjonalny za pomocą Barthel Index (BI). Określono skuteczność fizjoterapii (EP) po każdym miesiącu rehabilitacji (EP1, EP2, EP3).
Wyniki. Zaburzenia funkcji poznawczych (MMSE < 24) stwierdzono w przypadku 73% badanych, objawy depresji
(GDS > 5) u 65%. Średni wynik BI przy przyjęciu na oddział wyniósł 38.6 (± 20,2), a po trzech miesiącach hospita-
756

lizacji wzrósł istotnie do 59,2 (± 24,5) (p < 0,00001). Średnia skuteczność fizjoterapii (EP3) wyniosła 20.6 (± 15,0).
Niską skuteczność fizjoterapii osiągnęło 31% (n = 22) badanej grupy. Wykazano istotną zależność pomiędzy EP3
i MMSE (p = 0,00113), EP3 i GDS (p = 0,01223), EP3 i rozpoznaniem (p = 0,0106) oraz EP3 i EP1 (p < 0,00001).
Wnioski. Zwiększone ryzyko niepowodzenia fizjoterapii w warunkach NH obserwuje się u pacjentów z głębokimi zaburzeniami poznawczymi (MMSE < 11) oraz nasilonymi objawami depresji (GDS > 10). Największą szansę
na pomyślny przebieg procesu usprawniania w NH mają osoby rehabilitowanie z powodu urazów ortopedycznych. Najlepszym i najbardziej trafnym czynnikiem prognostycznym rezultatów fizjoterapii w NH jest skuteczność
fizjoterapii po miesiącu hospitalizacji. Brak poprawy stanu funkcjonalnego po pierwszym miesiącu pobytu w NH
jest wskazaniem do modyfikacji przyjętego modelu usprawniania lub przeniesienia pacjenta do specjalistycznego
oddziału rehabilitacyjnego (Adv Clin Exp Med 2010, 19, 6, 755–764).
Słowa kluczowe: wiek podeszły, skuteczność fizjoterapii, opieka długoterminowa.
Due to the steadily increasing average life expectancy, the percentage of elderly people requiring both medical care and physical rehabilitation
in a round-the-clock hospitalization setting is increasing every year. Efficient rehabilitation processes can considerably shorten the inpatient stay,
and the final results of rehabilitation are a major
factor in determining whether the patient will be
able to function independently at home or if permanent institutional care will be required. These
are very important issues, both in terms of costs
incurred by the healthcare system and social services, as well as the quality of life of elderly people.
Therefore, studies are often undertaken in order to
identify factors negatively affecting the efficiency
and the final outcomes of the process of physiotherapy among elderly people [1–5]. It is assumed
that accurate identification of those factors will enable appropriate action to be taken at the initial
stage of rehabilitation, which will finally lead to
improvement in the effectiveness of the rehabilitation process. In the literature one can find many
publications on the efficacy of physiotherapy (EP)
conducted in specialized inpatient rehabilitation
(IR) units. However, in many countries, including Poland, physiotherapy for elderly people is
also carried out in less specialized centers such as
nursing homes (NH). Rehabilitation performed in
a NH is less intensive and less specialized, but because of the lower costs of the patient’s stay, the
healthcare system offers more places in such facilities than in specialized rehabilitation units. Due to
the limited access to IR and the increasing needs
of the aging population, it is necessary to manage
existing resources appropriately so that facilities
offering round-the-clock medical care and rehabilitation are utilized effectively.
As previously mentioned, there are many reports in the literature on physiotherapy being
carried out in IR conditions. These publications
usually relate to a particular disease entity such as
a stroke or hip fracture [4–8]. This is required for
methodological reasons, but it also means that this
type of data is less useful in the differing condi-
tions of an NH, where patients with various diseases are admitted, and the main criteria are a high
degree of disability and an inability to function
independently at home. A review of scientific literature shows that there is no mention of the efficacy of physiotherapy carried out in less specialized units treating more diverse groups of patients.
Such studies would help to identify patients who
may significantly benefit from their stay in this
type of facility, and those who should be transferred to more specialized rehabilitation centers.
It is important for the decision regarding the optimal placement of elderly rehabilitation patients to
be taken as soon as possible, and not after several
weeks or even months of ineffective or minimally
effective rehabilitation at an NH. Therefore, the
purpose of the current study was to evaluate the
efficacy of three months of physiotherapy carried
out in a NH facility and to evaluate the impact of
several variables on the efficacy of physiotherapy,
including the patient’s age, functional status upon
admission to the facility, the major cause of the
disability and the presence of cognitive impairment and/or depressive symptoms. To maximize
the usefulness of the results and taking into consideration the observational nature of the study,
the variables put forward for analysis were those
commonly used in assessing patients upon admission to the facility (functional status, cognitive impairment, depressive symptoms).
Material and Methods
The study was performed in a nursing home
(NH). The study group consisted of geriatric patients admitted to the NH during the 12-month
research period who met the criteria for inclusion.
The patients agreed to participate in the study after being informed of the purpose and protocol
of the study and of the possibility of resigning at
any stage of the study. The inclusion criteria for
participation in the project were age over 60 years
and the ability to take a full cognitive function test.
Efficacy of Physiotherapy in Nursing Home
The criteria for exclusion from participation in the
study were aphasia; severe loss of vision or hearing
impairment preventing the patient from taking
a cognitive function test based on the Mini Mental
State Examination (MMSE); alcoholism; current
delirium or severe cognitive disorders; serious
mental disorders in the past, such as schizophrenia or other delusional disorders; bipolar disorder;
treated depressive disorders; or the patient’s refusal at any stage of the study. Among the 78 people
who qualified to participate in the study, seven
died during hospitalization, so the study ultimately
included 71 people aged from 61 to 97 years. The
mean age was 77.4 (± 7.3) years; 81.7% of the participants were women. The medical diagnoses of
the main causes of the disabilities requiring rehabilitation were as follows: 25.4% of the participants
had had orthopedic injuries (broken limbs resulting from a fall), 56.3% had had a stroke, and 18.3%
were being rehabilitated for chronic diseases of old
age (changes in degenerative arthritis, complications with diabetes and arteriosclerosis).
The MMSE was used to assess cognitive impairment (CI) [9]. The scoring ranges from 0 to
30 points; the lower the score, the more severe the
cognitive impairment is. The examination was
performed twice, first upon admission to the facility, between the third and fifth day of hospitalization (MMSE0), and a second time after a threemonth stay in the NH (MMSE3). In the case of
seniors whose intellectual state allowed accurate
examination of mood (MMSE ≥ 15, n = 51) [10,
11], a shortened 15-question version of the Geriatric Depression Scale (GDS) was performed.
Results above five points indicate the presence of
mood disorders; the higher the score, the more severe the symptoms of depression [12, 13]. The assessment of mood and well-being was performed
upon admission to the facility – between the third
and fifth day of hospitalization (GDS0) – and after
every month of the patient’s stay at the NH (GDS1,
GDS2, GDS3).
The Barthel Index (BI) was used to evaluate the
functional status of NH residents. This is a commonly used scale that measures functional performance of basic daily tasks (dressing, washing,
using the toilet alone, eating, walking, etc.) [14].
It is a universal tool that can be used to evaluate
every disease that limits a patient’s physical condition, because it assesses the capacity for self-sufficient functioning rather than any specific motor
dysfunction characterized by a particular disease
entity. A record sheet was completed by medical personnel on the basis of observations of the
patient’s real abilities, and not the opinion of the
therapist in charge. The scoring ranges from 0 to
100, where 100 means fully functional status, and
757
a result less than 20 indicates a severe condition
and a need for round-the-clock care. BI measurement was performed four times: upon admission
to the facility (BI0), after one month of rehabilitation (BI1), after two months (BI2) and after three
months of rehabilitation (BI3).
The variables were selected due to their universality in everyday practice: The variables analyzed were those that are typically evaluated upon
admission to the facility (functional status, cognitive impairment, depressive symptoms), and they
were measured using the same tools/scales that
are used daily by the medical staff. All of these
instruments have been commonly used for many
years by geriatric services. They are characterized
by high repeatability and reliability, and – just as
importantly – are simple and not time-consuming
to perform. The only modification of everyday
NH procedures made in the study was the repetition of the assessment procedures in subsequent
months of hospitalization. Regular evaluation of
the functional status of the rehabilitation patients
(BI0, BI1, BI2, and BI3) allowed the progress of the
physiotherapy to be monitored and the effectiveness of this process in a given unit of time to be
assessed. Similarly, evaluation of the mood and
well-being of hospitalized patients in subsequent
months (GDS0, GDS1, GDS2, and GDS3) provided
insight into the dynamics of mood changes during
the patients’ stay at the NH. The patients’ cognitive status was tested only twice (MMSE0, MMSE3)
since it is not as dynamic a variable as the remaining two, particularly since no form of cognitiveimpairment therapy was used in the center where
the study was carried out.
Absolute functional gain was deemed the measurement of the EP. The method for calculating
absolute functional gain was adapted from Rolland (2004), using the Barthel Index (BI) instead
of the Functional Independence Measure [8]. On
that basis, the following parameters describing the
progress of the rehabilitation process were calculated.
1) EP1 – The efficacy of physiotherapy after
the first month of rehabilitation (BI1 – BI0).
2) EP2 – The efficacy of physiotherapy after
the second month of rehabilitation (BI2 – BI0).
3) EP3 – The efficacy of physiotherapy after
the third month of rehabilitation (BI3 – BI0).
After that, on the basis of the EP3 parameter, the
patients were divided into the following subgroups:
– low efficacy of physiotherapy (from 0 to 10
points),
– medium efficacy of physiotherapy (from 15
to 25 points),
– high efficacy of physiotherapy (from 30 to
65 points).

Within these groups, analysis was carried out
based on the differences in the level of cognitive
disorders and severity of depressive symptoms, as
well as the age of patients and their functional status upon admission and in the subsequent months
of hospitalization. The correlation between particular parameters was also assessed. All analyses
were performed for the entire group (n = 71) as
well as in subgroups formed on the basis of the
diagnosis (orthopedic injuries, stroke and chronic
diseases). Non-parametric methods were used for
statistical analysis: the Wilcoxon test, the MannWhitney test, Spearman’s rank correlation, the
Kruskal-Wallis test and multiple regression.
Results
Within the framework of the research project 71 patients admitted to the rehabilitation unit
went through the full evaluation process. Detailed
characteristics of the study group are presented
in Table 1. On the basis of the MMSE test upon
admission, dementia of varying severity (MMSE
< 24) was found in 73% of the patients and low
mood (GDS > 5) in 65% of the respondents who
were able to take the Geriatric Depression Scale
(MMSE ≥ 15). Only 11% of the group showed
a proper intellectual performance (MMSE 27–30)
and were simultaneously free of mood disorders
(GDS scores in the 0–5 range). After three months
of hospitalization the cognitive status of participants did not change significantly (p = 0.10564),
but a significant improvement in mood was observed (p < 0.00001). The percentage of patients
with depressive symptoms (GDS > 5) decreased
from 65% to 31%. The average BI score at admission was 38.6 (± 20.2), and after three months of
hospitalization increased significantly to a level of
59.2 (± 24.5) (p < 0.00001), which implies a significant improvement in the functional status of
the rehabilitated patients. Nonetheless, the efficacy
of physiotherapy after three months of hospitalization differed greatly among individual patients,
varying from 0 to 65 points, with an average of
20.6 (± 15.0). A low EP3 was found in 31% of the
study group, 38% of them had an average EP3, and
the remaining 31% achieved a high EP3.
A correlation analysis showed that, among
other variables, the efficacy of physiotherapy was
dependent on the level of cognitive function in
patients at the time of admission to the facility (p
= 0.00113) as well as after three months of hospitalization (p = 0.00022) (Table 2). The worse the
cognitive state at both of the measured points, the
lower the efficacy of physiotherapy, understood
as the change in the BI within the given time period (BI3–BI0). The relationship between EP3 and
GDS1 was on the verge of statistical significance (p
= 0.05145); a strong relationship between EP3 and
GDS3 (p = 0.01223) was also observed. EP3 was
lower among patients with severe depressive symptoms in the first and third month of hospitalization
(Table 2). There was no interdependence between
BI0 and EP3: The functional status of the patient
upon admission to the facility did not significantly
influence the EP after three months of rehabilitation. Nonetheless, the parameters BI1, BI2 and BI3,
assessing functional status in successive months of
hospitalization, did show a significant relationship
with EP3 (Table 2). These observations were also
confirmed by comparing patients who achieved

the lowest efficacy of physiotherapy (0–10) versus
the highest (30–65) after three months of rehabilitation (Table 3).
To determine the “critical” (lowest) level of
cognitive function upon admission that later influences the course of rehabilitation, a correlation analysis was carried out excluding people
with profound dementia (MMSE0 < 11). MMSE
scores were no longer correlated with PF3 scores
(p = 0.06879). An analogical analysis was also carried out excluding those who showed symptoms of
severe depression after a month of rehabilitation
(GDS > 10). In this case too the GDS1 scores were
not correlated with the EP3 scores (p = 0.30463).
In terms of the disability diagnoses, the stroke
patients started rehabilitation in the worst condition as far as functional status was concerned.
A better level of functioning was represented by
the patients being rehabilitated due to chronic
diseases of old age and seniors with orthopedic
injuries. The differences between these groups increased during hospitalization (Table 4). Although
the stroke patients had the lowest functional condition upon admission to the facility, they achieved
final rehabilitation results comparable to those of
seniors with chronic diseases, which means that
the EP in the case of the stroke patients was higher. This observation is confirmed by the analyses
of the EP performed in the successive months of
the patients’ stay at the facility. The lowest EP was

noted in the patients with chronic diseases; slightly
better results were achieved by the stroke patients;
and by far the highest EP was achieved by seniors
being rehabilitated due to fractures and orthopedic injuries. After the first month of rehabilitation
the difference between the groups was insignificant (p = 0.2691), but it had clearly increased in
the subsequent months: It was (p = 0.0221) for
EP2, and (p = 0.0106) for EP3 (Table 4).
As for the other parameters tested, the compared groups varied significantly in age, cognitive
function upon admission to the facility as well as in
the GDS value in the second and third months of
rehabilitation (Table 4). The post-stroke patients
were far younger than the other two groups (p =
0.0094). Despite their advanced age, the patients
being rehabilitated due to orthopedic injuries had
the highest MMSE values upon admission to the
facility (p = 0.0166), which signifies the best intellectual status.
The analysis of the GDS values in the initial
period of hospitalization (GDS0, GDS1) indicated
that at the beginning all groups displayed similar
severity of depressive symptoms. After the second
and third months, the most severe mood symptoms were observed in the stroke patients. The differences between the groups were (p = 0.0040) for
GDS2 and (p = 0.0927) for GDS3 (Table 4). After
the third month of hospitalization, 42.0% of the
stroke patients continued to show symptoms of
depression (GDS > 5), in contrast to 28% of the
chronic-disease patients and 12.5% of the orthopedic-injury group. A correlation analysis indicated
that among the stroke patients, the values of GDS0,
GDS1, GDS2 and GDS3 are significantly related to
the EP3. The greater the severity of the depressive
disorders, the lower the efficacy of rehabilitation
is after three months of the rehabilitation process
(Table 5). No correlation between GDS and EP3
was observed in the remaining groups. However,
among the orthopedic patients, functional status
upon admission to the facility (BI0) was significantly related to the efficacy of physiotherapy after
three months (EP3) (p = 0.0204). This was not revealed in the other two groups (Table 5).
Multiple regression analysis was used to identify a set of factors that significantly influenced the
efficacy of physiotherapy performed in NH conditions. During the drafting of the regression model
from the available variables, those which showed
no significant relation to the EP were rejected
(age, BI0, GDS0), and it was assumed that only
those variables that were known at the early stage
of rehabilitation would be analyzed (no later than

first model, in which BI1, GDS1, MMSE0 and EP1
were taken into account, proved to be statistically
significant (p < 0.00001, R2 = 0.5983), but out of
all the components of the model only EP1 played
a significant role (p < 0.00001). In the second model, in addition to EP1, the type of disease that led
to the rehabilitation was also taken into account.
This entire model was significant (p < 0.00001),
as were each of its components. Over 70% of this
model was explained by the variability of the parameter EP3 (R² = 0.70193). The parameter EP1
had the largest prognostic value for the efficacy of
physiotherapy. In 95% of the patients who did not
show any signs of functional improvement after
the first month, the efficacy of physiotherapy after

three months of hospitalization was unsatisfactory
(from 0 to 10 points on the Barthel scale).
Discussion
The main aim of this research was to assess the
efficacy of three months of physiotherapy carried
out in a NH. The authors have established that in
the case of 1/3 of the elderly patients undergoing
rehabilitation in these conditions, EP3 is unsatisfactory (from 0 to 10 points on the Barthel scale).
Factors connected with low EP3 were then sought,
to enable those patients who are at the highest risk
of physiotherapy failure to be identified as quickly
as possible, so that the model of rehabilitation can
be modified appropriately or the patients can be
transferred to centers offering more specialized
therapy. Finding a way to identify such patients on
the basis of parameters that are known in the initial
phase of their qualifying for a stay in a NH (age,
BI0, MMSE0, GDS0, diagnosis) would be considered a full success. However, the results obtained
in the study have not provided such a possibility.
EP & Age
The current study has not demonstrated any
significant relationship between the efficacy of
physiotherapy and the age of the participants,
even though some authors report a clear interdependence: The younger the patients, the better the
effects of rehabilitation [1, 2, 15]. The nature of
our study, which in contrast to the cited reports
compares people with various different ailments,
probably had a significant impact on the results
obtained. The highest average age was reported
among the patients being rehabilitated due to orthopedic injuries; this same group was also characterized by the best state of cognitive functions
in both assessments (MMSE0, MMSE3) and the
lowest intensity of depressive symptoms in the
second and third months of hospitalization. Even
after the first month of their stay at the facility this
group of patients showed significant improvement
in functional status, manifested both in absolute
BI values and in better efficacy of physiotherapy
(EP2, EP3) (Table 4). It therefore appears that in
the population of patients hospitalized in the NH,
age is not an independent factor increasing the
risk of physiotherapy failure, even among the oldest patients. Rather, it is the type of disability and
other additional factors (cognitive impairment,
depression) which largely determine the outcome
of rehabilitation.
EP & BI0
In this study the authors initially assumed that
the patient’s level of functional performance upon
admission to the facility may be a significant factor
shaping the course of the physiotherapy process.
Many publications support such a criterion [1–5,
16, 17]. However, it is worth noting the methodological differences between particular experiments. In the cited studies the researchers usually
assessed the effects of physiotherapy by considering the functional status at particular measuring points – for example, after one two and three
months, and also over longer periods, one year to
three years after the completion of rehabilitation.
They concluded that the worse the initial condi-
762

tion, the worse the patient’s condition was at the
subsequent measurement points. In contrast, the
current study assessed the difference between the
final and the initial functional status – it was this
change that was regarded as defining the efficacy
of physiotherapy. The results obtained do not support the thesis that the worse the initial condition,
the worse the EP will be after three months of rehabilitation. This means that even people with a very
severe degree of disability can benefit considerably
from rehabilitation carried out in NH conditions,
and can improve their functional performance in
a way comparable to patients who commenced
hospitalization in better physical condition.
EP & MMSE
Discussion has been going on for many years
regarding the impact of cognitive impairment on
the course and final outcomes of the process of
physiotherapy, and the conclusions are ambiguous. CI is regarded as one of the factors related to
the length of stay in geriatric rehabilitation units
[18]. Many authors argue moreover that CI patients achieve poorer end results in physiotherapy
[19–22]. On the basis of such arguments one can
suppose that demented patients are characterized
by a reduced capacity to benefit from rehabilitation.
More in-depth analysis suggests that the cause of
failure may also be a higher rate of in-hospital falls
and significantly less individual and group therapy per hospital day [23]. There are, however, also
reports of patients with CI achieving comparable
effects from physiotherapy as cognitively-normal
individuals, if we adopt absolute functional gain
as the measure of the efficacy of therapy (discharge
functional status minus admission functional status) [8, 24].
In the current study a significant correlation
has been shown between the level of cognitive impairment (MMSE value) and reduced efficacy of
physiotherapy, defined as the difference between
the final and initial states (BI3–BI0). But after excluding the most severely demented patients
(MMSE < 11) from the analysis, the presence of
CI ceases to correlate with EP. Therefore, it seems
that within the studied group of elderly people being rehabilitated in NH conditions, only patients
with severe dementia show an increased risk of
physiotherapy failure. The reason for this may be
communication problems with this type of patient,
or the presence of intensified behavioral disorders.
This leads to a reduced amount of treatment received, because the time that can be devoted to the
patient is used inefficiently. Furthermore, it must
be remembered that most of the more intellectually capable patients improve their physical fitness
by doing daily activities (self-washing, dressing, tidying up, moving around within the center, etc.),
while people who are deeply disturbed often have
problems carrying out daily activities, or even (in
the absence of appropriate stimuli from care workers) give up such activities. As a result, such patients are washed, dressed, etc., entirely by the staff,
which has a negative influence on their physical
condition, and subsequently on the effects of physiotherapy. The majority of these issues can, however, be avoided through appropriate organization
of work at the facility, the selection of appropriate therapy methods, and the proper conduct of
medical personnel who can effectively communicate with the patient, react in the event of behavioral disorders and ensure essential daily activity.
Lenze et al. (2007) reported that CI people who received therapy at inpatient rehabilitation facilities
had significantly better functional outcomes than
similarly impaired patients at nursing homes [ 25].
Thus it appears that the presence of severe cognitive impairment is an indication for rehabilitation
in a specialized unit and not in a NH.
EP & Depression
As in the case of CI, there is no clear and definite opinion regarding the impact of mood disorders on the outcomes of rehabilitation. Depending
on the methodological assumptions of individual
research projects (the ways functional capabilities are assessed, the duration of the observation
of patients, the type of disease, etc.), the literature reveals different and sometimes conflicting
reports. Many authors argue that the presence of
depression negatively impinges on the course of
the physiotherapy process [6, 7], which can prolong the duration of rehabilitation [26] and even
result in a transfer to a nursing home [7]. Van de
Weg et al., however, believe that there is no significant difference between those with depression and
those without depression as far as functional gain
achieved due to rehabilitation is concerned [27].
Similarly, Cassidy (2004) argues that depression is
not a determining factor either for the effectiveness of rehabilitation or for the length of inpatient
stay [4].
The results of the current study are also ambiguous. On the one hand, we disproved the hypothesis that GDS0 correlates with EP3. But GDS1
does show a significant relationship with EP3
(more intensified mood disorders reduce the effectiveness of physiotherapy after a three-month stay
in a NH). Perhaps the screening tests performed
in the first days of hospitalization are affected by
a major error arising from temporary mood disorders associated with the elderly patient’s adaptation
Efficacy of Physiotherapy in Nursing Home
to new conditions, and it’s only after four weeks at
the facility that the assessment reflects the patient’s
real emotional state. It therefore seems more reliable and credible when the assessment is carried
out after a period of adaptation, and not in the first
few days after admission to the NH or other longterm care facility. Moreover, this study established
that there is also a significant correlation between
GDS3 and EP3. However, in our understanding,
the presence of depressive symptoms in this case
is a result of physiotherapy failure rather than its
cause. People whose functional status is clearly
improving have reasons to be happy and feel well,
while the remaining patients have real grounds for
concern about their health and their chances for
independent existence, and this negatively impacts
their emotional state.
Another observation that arises from the
analysis of the results obtained is the fact that the
severity of depressive symptoms varies from one
particular disease entity to another; it is clearly
the highest among stroke patients. This is also
the only group in which there is no significant
improvement in mood regardless of the rehabilitation carried out: After three months of therapy,
42% of the respondents still exhibit symptoms of
depression. Furthermore, it is in post-stroke individuals that the relationship of depression with
EP3 is the strongest in all of the stages of hospital-
763
ization (GDS0, GDS1, GDS2 and GDS3). It should
be emphasized, however, that – as in the case of
the entire population studied at the NH – if the patients with the greatest severity of mood disorders
(GDS > 10) are excluded from the analysis, the
GDS value ceases to have a relationship with EP.
Thus, the increased risk of physiotherapy failure
in NH conditions occurs primarily in post-stroke
patients whose intensified depressive symptoms
have been established (GDS > 10). It seems justified to carry out the rehabilitation of such patients in a specialized unit where antidepressant
therapy can be provided along with a standard
rehabilitation process. The aforementioned study
by Lenze et al. (2007) found that people with
depression rehabilitated in this type of facility
achieve comparable results to patients without
mood disorders [25].
The authors concluded that an increased risk
of physiotherapy failure in NH conditions was
observed in patients with profound cognitive impairments (MMSE < 11) and severe depressive
symptoms (GDS > 10). The strongest progress in
rehabilitation in the NH was observed among patients being rehabilitated due to orthopedic injuries. The best prognostic factor for the outcome of
physiotherapy after a three-month stay in a NH is
the efficacy of physiotherapy after one month of
hospitalization.
