This 3 arm parallel, multi-centre, assessor blind, randomised control trial was conducted within outpatient neurorehabilitation services. Community dwelling stroke survivors with walking speed <0.8m/s, lower limb paresis and no severe visual impairments. Over-ground visual cue training (O-VCT), Treadmill based visual cue training (T-VCT), and Usual care (UC) delivered by physiotherapists twice weekly for 8 weeks. Participants were randomised using computer generated random permutated balanced blocks of randomly varying size. Recruitment, retention, adherence, adverse events and mobility and balance were measured before randomisation, post-intervention and at four weeks follow-up. Fifty-six participants participated (18 T-VCT, 19 O-VCT, 19 UC). Thirty-four completed treatment and follow-up assessments. Of the participants that completed, adherence was good with 16 treatments provided over (median of) 8.4, 7.5 and 9 weeks for T-VCT, O-VCT and UC respectively. No adverse events were reported. Post-treatment improvements in walking speed, symmetry, balance and functional mobility were seen in all treatment arms. Outpatient based treadmill and over-ground walking adaptability practice using visual cues are feasible and may improve mobility and balance. Future studies should continue a carefully phased approach using identified methods to improve retention. Clinicaltrials.gov NCT01600391.

Here, we report patients' views of patient-led mirror therapy and lower limb exercises. 94 stroke survivors with upper and lower limb limitations at least 1-week post-stroke undertook 4 weeks of daily patient-led mirror therapy or lower limb exercise, then completed questionnaires regarding their experience and satisfaction. A convenience random sample of 20 participants also completed a semi-structured telephone interview to consider their experience in more detail and to capture their longer term impressions. Participants were generally positive about patient-led therapy. About 71% found it useful; 68% enjoyed it; 59% felt it "worked" and 88% would recommend it to other patients. Exercise was viewed more positively than the mirror therapy. Difficulties includ...

This article reports the lessons learnt while recruiting stroke rehabilitation patients to a multi-centre randomised control trial. As intended, 94 participants were recruited from 12 inpatient stroke rehabilitation services in Northwest England over 12 months; however, recruitment rates were highly varied (from 0.6 to 2.5 participants per site per month) as were the nature of the stroke services and the personnel available. Consequently, bespoke recruitment procedures were needed at each site. As the assessment skills needed to screen for the selection criteria were specific to therapists, our most common strategy was for the hospital therapists to screen patients and make referrals directly to the trial team. However, we identified several strategies undertaken by the research nurse in the highest recruiting site that appeared to positively impact on recruitment. These strategies included involving the whole multidisciplinary team, being part of the stroke team, facilitating contact between the clinical and trial teams and using inclusive recruitment and watchful waiting strategies. Rehabilitation trials frequently require skilled assessments by therapists, rather than by doctors or nurses to identify potential participants. Thus, research support models need to include suitably skilled trial therapists. Recruitment can be enhanced by enthusiastic, regular and structured engagement with the entire stroke multidisciplinary team and by using inclusive recruitment and 'watchful waiting' strategies to identify and monitor potential participants.

Patient-led therapy has the potential to increase the amount of therapy patients undertake during stroke rehabilitation and to enhance recovery. Our objective was to assess the feasibility and acceptability of 2 patient-led therapies during the acute stages of stroke care: mirror therapy for the upper limb and lower-limb exercises for the lower limb. Methods. This was a blind assessed, multicenter, pragmatic randomized controlled trial of patient-led upper-limb mirror therapy and patient-led lower leg exercises. Stroke survivors with upper and lower limb limitations, undergoing inpatient rehabilitation and able to consent were recruited at least 1 week poststroke. Results. Both interventions proved feasible, with >90% retention. No serious adverse events were reported. Both groups did less therapy than recommended; typically 5 to 15 minutes for 7 days or less. Participants receiving mirror therapy (n = 63) tended to do less practice than those doing lowe...

This study sought to measure the effects of competing cognitive demands on the stepping patterns of stroke survivors, compared to healthy age-match adults, during turning as a putative mechanism for falls. Walking and turning (90°) was assessed under single (walking and turning alone) and dual task (subtracting serial 3s while walking and turning) conditions using an electronic, pressure-sensitive walkway. Dependent measures were time to turn, variability in time to turn, step length, step width and single support time during three steps of the turn. Turning ability in single and dual task conditions was compared between stroke survivors (n=17, mean ± SD: 59 ± 113 months post-stroke, 64 ± 10 years of age) and age-matched healthy counterparts (n=15). Both groups took longer, were more variable, tended to widen the second step and, crucially, increased single support time on the inside leg of the turn while turning and distracted. Increased single support time during turning may represent biomechanical mechanism, within stepping patterns of turning under distraction, for increased risk of falls for both stroke survivors and older adults.

One way to manage this to use an orthosis to control the movement of the affected joints but evidence for their benefit is lacking. To determine the effectiveness of upper or lower limb orthoses on activity and impairment in people with stroke and other non-progressive brain lesions. In February 2007 we searched the trials registers of the Cochrane Stroke, Movement Disorders and Injuries Groups, the Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2007), MEDLINE (from 1966), EMBASE (from 1980), CINAHL (from 1983), AMED (from 1985), PsycINFO (from 1967) and RECAL (from 1990), and other databases and trials registers. We screened reference lists, contacted lead authors and other researchers in the field. We included randomised controlled trials of orthoses applied to the upper or lower limb in people with stroke and other non-progressive brain lesions. Two review authors independently identified trials, extracted data, and assessed trial quality. Results for continuous outcomes were combined and analysed using mean difference or standardised mean difference, both with 95% confidence intervals and fixed-effect model. We analysed 14 trials with 429 participants. The overall effect of lower limb orthoses on walking disability (speed), walking impairment (step/stride length) and balance impairment (weight distribution in standing) was significant and beneficial. There was no significant effect on postural sway (balance impairment) or mobility disability but the numbers of studies and participants were low. However, these were all cross-over trials that looked at the immediate effect while wearing the orthosis; they did not assess the effects of wearing an orthosis over the long term. Upper limb orthoses showed no effect on upper limb function, range of movement at the wrist, fingers or thumb, nor pain. However, this was based on only three trials. A lower limb orthosis can improve walking and balance but the included studies have only examined the immediate effects while wearing the orthosis; the effects of long-term use have not been investigated. An upper limb orthosis does not effect on upper limb function, range of movement at the wrist, fingers or thumb, nor pain, but this conclusion is based on only three trials.

Stair climbing results in around six times more compressive load transmitted through the knee joint than walking on level ground. The purpose of this study was to assess whether lateral wedge insoles would reduce medial compartment knee loading when ascending and descending stairs in patients with medial knee osteoarthritis. Eight patients with medial knee osteoarthritis were tested in random order with and without a pair of 5° off-the-shelf lateral wedge insoles for two separate activities (stair ascent and stair descent). Kinematic and kinetic data were collected for the lower extremity using a sixteen camera motion capture system and two force plates. Primary outcome measures were the external knee adduction moment and the knee adduction angular impulse. During stair ascent and descent, lateral wedge insoles significantly (P<0.05) reduced the 1st peak external knee adduction moment in early stance (ascent 6.8%, descent 8.4%), the trough in mid stance (ascent 13%, descent 10.7%), 2nd peak in the late stance (ascent 15%, descent 8.3%) and the knee adduction angular impulse compared to the control (standard shoe) with large effect sizes (0.75-0.95). In this first study on stairs, lateral wedge insoles consistently reduced the overall magnitude of medial compartment loading during stair ascent and descent. Further research is needed to determine the relationship of this with clinical results when ascending and descending stairs with lateral wedge insoles.

The paper is based on findings from a qualitative case study of a multidisciplinary in-patient neurorehabilitation team in one UK NHS trust who routinely collected standardised outcome measures. Data were collected using non-participant observation of 16 MDT meetings and semi-structured interviews with 11 practitioners representing different professional groups. Our analysis suggests that clinicians drew on tacit knowledge to supplement, adjust or dismiss 'the scores' in making judgements about a patients' likely progress in rehabilitation, their change (or lack of) during therapy and their need for support on discharge. In many cases, the scores accorded with clinicians' tacit knowledge of the patient, and were used to reinforce this opinion, rather than determine it. In other cases, the scores, in particular the Barthel Index, provided a partial picture of the patient and in these circumstances, clinicians employed tacit knowledge to fill in the gaps. In some cases, the scores and tacit knowledge diverged and clinicians preferred to rely on their clinical experience and intuition and adjusted or downplayed the accuracy of the scores. We conclude that there are limits to the advantages of quantifying and standardising assessments of health within routine clinical practice and that standardised outcome measures can support, rather than determine clinical judgement. Tacit knowledge is essential to produce and interpret this form of encoded knowledge and to balance its significance against other information about the patient in making decisions about patient care.

However, clinicians report difficulty selecting appropriate tools from the wide range available. We aimed to systematically review the psychometric properties and clinical utility of mood screening tools for stroke survivors. Electronic databases (AMED, EMBASE, CINAHL, Medline and PsycINFO) were searched to identify studies assessing the sensitivity and specificity of mood screening tools. Tools that demonstrated at least 80% sensitivity and 60% specificity with stroke survivors with identifiable cut-off scores indicating major and/or any mood disorder in at least one study were selected and clinical utility was assessed. Those with high clinical utility (against predefined criteria) were selected for recommendation. Thirty papers examining 27 screening tools were identified and 16 tools met the psychometric and clinical utility criteria: 10 were verbal self-report tools, four were observational and two incorporated visual prompts for those with communication problems. Only the Stroke Aphasic Depression Questionnaire -Hospital version (SADQ-H) met all the psychometric and utility criteria. The nine-item Patient Health Questionnaire (PHQ-9) can detect major depression and the 15-item Geriatric Depression Scale (GDS-15) can identify milder symptoms; both are feasible to use in clinical practice. The Hospital Anxiety and Depression Scale (HADS) was the only tool able to identify anxiety accurately, but clinical utility was mixed. Valid and clinically feasible mood screening tools for stroke have been identified but methodological inconsistency prevented recommendations about the optimal cut-off scores.

The gait parameters measured were: velocity, stride length, step length and symmetry using a paper walkway. The subjects walked without (phase A) and then with (phase B) the AFO. The subjects' views were sought using a semi-structured questionnaire. The data were displayed graphically and analysed using autocorrelations and paired t-tests to compare phases A and B in each parameter for each subject. All subjects showed significant improvements in velocity, stride and step length in the sound and weak legs, and three of the subjects showed significant improvements in symmetry. The subjects all viewed the AFO positively and felt that it improved their walking. They placed more emphasis on the changes in disability than impairment.

Only the Stroke Aphasic Depression Questionnaire -Hospital version (SADQ-H) met all the psychometric and utility criteria. The nine-item Patient Health Questionnaire (PHQ-9) can detect major depression and the 15-item Geriatric Depression Scale (GDS-15) can identify milder symptoms; both are feasible to use in clinical practice. The Hospital Anxiety and Depression Scale (HADS) was the only tool able to identify anxiety accurately, but clinical utility was mixed. Valid and clinically feasible mood screening tools for stroke have been identified but methodological inconsistency prevented recommendations about the optimal cut-off scores.

The gait parameters measured were: velocity, stride length, step length and symmetry using a paper walkway. The subjects walked without (phase A) and then with (phase B) the AFO. The subjects' views were sought using a semi-structured questionnaire. The data were displayed graphically and analysed using autocorrelations and paired t-tests to compare phases A and B in each parameter for each subject. All subjects showed significant improvements in velocity, stride and step length in the sound and weak legs, and three of the subjects showed significant improvements in symmetry. The subjects all viewed the AFO positively and felt that it improved their walking. They placed more emphasis on the changes in disability than impairment.
