Proprioception

In this chapter, I will offer both an appreciative and critical examination of David Bohm’s vision
and practice of dialogue and how it relates to the field of dialogue studies. Bohm’s conception
of dialogue was ground-breaking in its time due to its emphasis on consciousness and unfolding
a fundamentally different order of communication mediated by collective awareness and
insight into the nature of thought and the dialogue process as a whole. Bohm’s conception and
process aspired to bring the human project of sharing meaning, values and learning forward by
introducing practices or ways of being with the dialogue process that interrupted conventional
practice at that time. In this paper, I examine key contributions of Bohm’s work as well as a
number of critiques and limitations of the practice. Finally, I comment briefly on the feasibility
of Bohm’s practice as a transformative approach to dialogue.

Objectives: Significant loss of playing time and the impact of treatment costs due to lower limb injury in football demonstrates a need for improved protocols for injury risk reduction. The aim of the present study is to assess the effect of a proprioceptive training program on the lower limb dynamic stability of elite footballers. Methods: A total of 16 elite premier league footballers were randomly allocated by matched pair design to a 8-week proprioception training group (group A, n = 8) or nontraining group (group B, n = 8), to determine the effect of this training over a 16-week period. Group A completed 8 weeks of bilateral proprioceptive training, 5 times per week for 10 minutes. The Biodex Stability System measures of overall stability index, anterior–posterior (A–P), and medial–lateral stability (M–L) at levels 8-6-4-1 were taken for both groups at baseline, 4, 8, and 16 weeks. Main effects of time, level of stability, and direction of stability were determined, with compar...

We investigated the possibility of controlling reaching movements on the sole basis of central mechanisms, i.e., without peripheral feedback on hand and target positions. A deafferented subject (GL) and control subjects reached with the unseen hand for a straight-ahead target that could be displaced laterally at movement onset. The shifted target was continuously or briefly lit, or not visible. In

Modality specificity of human primary somatosensory cortex was studied by recording somatosensory evoked potentials (SEPs) from subdural electrodes in a patient with intractable focal motor seizure. A newly developed device was used for selectively activating proprioception. The spatial and temporal distributions of proprioception-related SEPs elicited by brisk passive flexion movement at the proximal interphalangeal (PIP) joint of the middle finger

This review article deals with some effects of neck muscle proprioception on human balance, gait trajectory, subjective straight-ahead (SSA), and self-motion perception. These effects are easily observed during neck muscle vibration, a strong stimulus for the spindle primary afferent fibers. We first remind the early findings on human balance, gait trajectory, SSA, induced by limb, and neck muscle vibration. Then, more recent findings on self-motion perception of vestibular origin are described. The use of a vestibular asymmetric yaw-rotation stimulus for emphasizing the proprioceptive modulation of motion perception from the neck is mentioned. In addition, an attempt has been made to conjointly discuss the effects of unilateral neck proprioception on motion perception, SSA, and walking trajectory. Neck vibration also induces persistent aftereffects on the SSA and on self-motion perception of vestibular origin. These perceptive effects depend on intensity, duration, side of the cond...

We tested the hypothesis that vibratory thresholds in the elderly are related to mobility. In all, 629 older persons without dementia underwent testing including 11 lower extremity performance measures and modified United Parkinson's Disease Rating Scale (UPDRS), summarized as composite mobility and global parkinsonian signs. Vibratory thresholds were measured at the ankle and toes bilaterally using the graduated Rydel–Seiffer tuning fork. In linear regression models adjusted for age, sex, and education, vibratory threshold was associated with composite mobility (estimate, 0.047, SE = 0.011, P < 0.001) and global parkinsonian signs score (estimate, −0.252, SE = 0.126, P = 0.047). These findings were primarily due to the association of vibratory threshold with gait and balance components of composite mobility and parkinsonian gait. These results were unchanged when we controlled for body mass index, physical activity, cognition, depression, vascular risk factors, vascular disease burden, joint pain, and falls. Vibratory thresholds are associated with mobility, supporting the link between peripheral sensory nerve function and mobility in the elderly. Muscle Nerve, 2009

The present study was aimed to investigate the role of various forms of training in improving the proprioception of the knee joint in patients with osteoarthritis of knee. Sixty participants (male and female) with knee Osteoarthritis of Grade II and III (Kellgren-Lawrence criteria) in the age range of 50-73 years were recruited from the Department of Orthopedics, Hospital Universiti Sains Malaysia. The recruited participants were taken to the Exercise and Sports science laboratory and the laboratory of School of Medical Sciences, Universiti Sains Malaysia for baseline assessment. The level of proprioception was assessed with the aid of isokinetic device BIODEX 4 System Pro. The participants were randomly categorized into four groups (Gr.) (Viz. Gr. A, Gr. B, Gr. C and Gr. D) and thus each group consisted of 18 participants. Gr. A participants received Conventional Physiotherapy consisting of strengthening exercises; stretching exercises and range of motion exercises. Gr. B received Isokinetic Training at velocities of 90° and 150°/second. Gr. C participants received EMG Biofeedback training with Mega ME 6000 device and Gr.D participants recieved a combined intervention of isokinetic training and EMG Biofeedback. The training protocol was designed for 25-30 minutes per session; 2 sessions per week for 10 weeks (20 sessions). The assessment was done after 5th week of training (mid term) and after 10th week of training (post) following baseline assessment protocol. A follow up assessment was performed after the 14th and 18th week to assess the after effect of training. Meanwhile the participants were not given any training after the 10 week period. They were also adviced not to get engaged in any sort of physical training, exercise or sport programme. Repeated measure of ANOVA revealed that, all interventions helped in improving the proprioception of the knee joint however post hoc analyses implicated that a combined intervention of Isokinetic Training and EMG biofeedback was beneficial in enhancing proprioception than the conventional physiotherapy (P<.05).

The purpose of this study was to investigate the effectiveness of Johnstone pressure splints (JPSs) on spasticity and cutaneous sensory inputs in children with spastic cerebral palsy (CP). Thirty-four children with spastic diplegic CP participated in this study. Children whose motor development levels were similar were divided into a treatment and a control group. Each group consisted of 17 participants (six females and 11 males). Mean age of the treatment group was 48.82 months (SEM 4.42), and the control group, 47.52 months (SEM 5.27). The treatment group underwent Bobath's neurodevelopmental therapy (NDT) combined with JPSs. The control group underwent NDT alone five days a week for three months. Before and after treatments, lower-extremity passive range of motion (ROM) by goniometric measurements, spasticity by Modified Ashworth Scale (MAS), and somatosensory evoked potentials (SEPs) were measured. Passive ROM showed significant improvements in both groups (p<0.01). In the treatment group, all MAS scores increased. In the control group, the difference was significant except for values of internal rotator muscles. Improvements in passive ROM in the treatment group were significantly higher than the control group except in hip abduction and external rotation (p<0.05). MAS scores of the treatment group were significantly higher than the control group (p<0.05). SEP values increased in both groups but values of the treatment group were significantly higher than the control group (p<0.05).

The aim of the present study was to investigate the immediate effects of static and proprioceptive neuromuscular facilitation (PNF) stretching on the flexibility of hip adductors in female ballet dancers. Forty-five subjects (age: 28.5 ± 8.0 years; minimum two years of ballet training) were randomly assigned to three groups: PNF (contract-release technique), Static, and Control. Subjects in the PNF and Static groups performed four sets of 30 second stretching with an interval of 30 seconds between sets. The control group stayed at rest for the same time spent by the PNF and Static groups during the stretching sessions. Maximal range of motion was measured before and immediately after the experimental and control protocols in all groups. The results indicated significant differences between pre- and post-stretching flexibility in both PNF and Static groups (p &lt; 0.0001; effect size = 0.24 and 0.39, respectively), whereas no change was identified in the Control group (p = 0.265).

Le but de cette étude était d'examiner l'effet d'un programme d'activités physiques sur la stabilité et le contrôle attentionnel de la posture lors de la réalisation concomitante d'une tâche cognitive attentionnelle chez des personnes âgées en perte d'autonomie.Douze personnes âgées (M = 81,4 ± 9 ans), institutionnalisées en structure gériatrique ont participé à un programme d'activités physiques de type posture–équilibration–motricité (PEM) pendant 12 semaines à raison de deux séances d'une heure par semaine. Les paramètres stabilométriques de surface et de longueur du trajet parcouru par le centre de pression plantaire (CPP), les yeux ouverts (YO) et les yeux fermés (YF), en condition simple-tâche et en condition double-tâche sur sol dur ont été analysés avant et après le programme d'entraînement. En condition double-tâche, les sujets effectuaient, lors de l'évaluation stabilométrique, une tâche cognitive attentionnelle de génération de chiffres aléatoires.Les principaux résultats ont révélé que seule la longueur du trajet parcouru par le CPP était plus importante en condition double-tâche qu'en condition simple-tâche (p = 0,05). Lors de l'évaluation initiale, la performance à la tâche cognitive était significativement moins bonne en condition double-tâche (debout) qu'en condition simple-tâche (assis), seulement dans la modalité YF mais pas dans la modalité YO (p < 0,05). Toutefois, à l'issue du programme d'entraînement, les performances à la tâche cognitive ne se différenciaient plus (n.s.) pour les deux conditions assis YF et debout YF.L'entraînement a permis d'améliorer la capacité des sujets à réaliser une tâche mentale attentionnelle tout en maintenant un équilibre correct, notamment les yeux fermés. Bien que les performances stabilométriques semblaient moins bonnes en condition double-tâche qu'en condition simple-tâche, ces résultats pourraient être interprétés comme une amélioration, suite au programme d'entraînement, du contrôle attentionnel du maintien de la posture. Les limites méthodologiques de cette étude sont ensuite discutées.We aimed to examine the effect of a physical activity program on postural sway and on the attentional control of postural abilities in elderly frail adults.Twelve older adults (age 81.4 ± 9 years) institutionalised in a geriatric care institution participated in the physical activity program posture–balance–mobility (PBM) twice a week (1 hour per session) for 12 weeks. We analysed stabilometric data for surface and length of the center of pressure (COP) sway, with eyes open and eyes closed, under single-task and dual-task conditions on a firm floor before and after the training program. During the static postural evaluation and under the dual-task condition, subjects performed an attention-demanding cognitive task, the random number generation task.Only the length of COP sway was more important under the dual-task condition than under the single-task condition (p = 0.05). At baseline, cognitive performance was significantly weaker under the dual-task condition (standing) than under the single-task condition (seated), with eyes closed but not eyes open (p < 0.05). However, after the training program, the performance of the cognitive task did not significantly differ between the dual-task condition with eyes closed and the single-task condition with eyes closed.The training program allowed elderly subjects to improve their ability to perform an attention-demanding cognitive task while standing still, in particular with their eyes closed. Although balance seemed to be less stable under the dual-task condition than under the single-task condition, these results could be interpreted as an improvement of the attentional control of postural stability.

Proprioception is the basic element of the spontaneous control of movement, balance and joint stability. Therefore, it is necessary for the execution of walking and daily and sport activities. Loss of proprioception of the knee, which may cause a new injury, is important to evaluate the position sense of the joint during the rehabilitation period. However, the evaluation methods that are used are very expensive, complicated and non-portable, or the measuring method is difficult to implement. We demonstrated the validity and reliability of knee proprioception measurements performed in the open kinetic chain position and closed kinetic chain position with a dual inclinometer. We assessed the validity and intra-tester reliability of a digital inclinometer for measuring the knee joint position sense in different positions. Clinical laboratory. We enrolled 22 participants (age = 21.8 ± 0.95 years, height = 172 ± 9.1 cm, weight = 64.9 ± 14 kg) into the study. The same investigator used an...

Proprioceptive training has been shown to reduce the incidence of ankle sprains in different sports. It can also improve rehabilitation after anterior cruciate ligament (ACL) injuries whether treated operatively or nonoperatively. Since ACL injuries lead to long absence from sports and are one of the main causes of permanent sports disability, it is essential to try to prevent them. In a prospective controlled study of 600 soccer players in 40 semiprofessional or amateur teams, we studied the possible preventive effect of a gradually increasing proprioceptive training on four different types of wobble-boards during three soccer seasons. Three hundred players were instructed to train 20 min per day with 5 different phases of increasing difficulty. The first phase consisted of balance training without any balance board; phase 2 of training on a rectangular balance board; phase 3 of training on a round board; phase 4 of training on a combined round and rectangular board; phase 5 of training on a so-called BABS board. A control group of 300 players from other, comparable teams trained “normally” and received no special balance training. Both groups were observed for three whole soccer seasons, and possible ACL lesions were diagnosed by clinical examination, KT-1000 measurements, magnetic resonance imaging or computed tomography, and arthroscopy. We found an incidence of 1.15 ACL injuries per team per year in the control group and 0.15 injuries per team per year in the proprioceptively trained group (P

A literature review examining conventional proprioceptive interventions (i.e. unstable surface training) and novel proprioceptive interventions (i.e. tactile and vibratory stimulation) of the ankle and foot on measures of proprioception (i.e. joint position sense, joint movement perception threshold) and balance/postural sway (i.e. center-of-pressure) in young healthy adults and those with FAI or acute ankle injury. Directives for ankle/foot rehabilitation protocols and propositions for future research are included.

Author(s): Nealand, Eireene | Advisor(s): Godzich, Wlad | Abstract: In a 1965 manifesto called &quot;Proprioception&quot; Charles Olson, the poet often known as the father of the American avant-garde, suggests that poets wanting to implement their open verse poetics explore a physiological faculty associated with the way we experience motion, texture, and shifts. This dissertation attempts to do so.Distinguishing between artworks associated with a perceptual model of the senses and those associated with a proprioceptive one, I show that a proprioceptive approach can be helpfully explored through a look at the work of Marcel Duchamp, who is best known for his anti-representational approach to art, one which includes the spectator as a part of the canvas. Using the example of spectator experience of a pointillist painting by Georges Seurat in which differently colored dots reach each of our eyes at different times, I show that juxtaposition-based art allows viewers to navigate the pai...

This study aimed to establish the effects of hospital- and home-based proprioceptive and strengthening exercise programs on proprioception, pain, and functional status in patients with knee osteoarthritis (OA). Sixty patients with bilateral knee OA were randomly allocated into either a home-based or hospital-based exercise program. Hospital-based exercise group (n=30, mean age 50.23±9.07 years) received functional training program with proprioceptive ability, ice, and home exercises. Home-based exercise group (n=30, mean age 54.4±7.9 years) had a program of ice and home exercises. Treatment programs was conducted 5 days per week for 6 weeks (30 sessions). Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Monitorized Functional Squat System-Proprioceptive Test (MFSS), timed performance test (TUG), and visual analogue scale (VAS) for the intensity of pain were used to quantify the variables. Both groups demonstrated significant improvement when pre- and post-trea...
