The purpose was to investigate the postural consequences of proprioceptive perturbation Triceps Surae and Peroneus Longus muscles. These muscles are known control posture respectively in sagittal frontal planes during standing. Standard parameters time course center pressure (CoP) displacements were recorded 21 young adults, instructed maintain their balance tendon vibration. Following 4 s baseline recording, three types vibration (80 Hz) applied for 20 each on or Achilles tendons, either...

<b>Aims:</b> To investigate the ability of patients with Parkinson's disease to perform a rotation around longitudinal axis body. Three questions were raised. Is body impaired in disease? there level kinematic chain from head foot at which impairment is more severe? deficit related general slowness movement <b>Methods:</b> Kinematic data recorded. The temporal organisation during gait initiation was analysed 10 disease, who all an advanced stage and had experienced falls freezing their daily...

In hemiparetic patients, the skeletal muscle is mainly affected with a combination of abnormalities (denervation, remodeling, spasticity, and eventually muscular atrophy).This study examined role eccentric exercise in strengthening muscles lower extremity ultimately improving autonomy patients post-stroke hemiparesis during gait.Thirty-seven adults were recruited, randomized into control group (n = 19) an intervention receiving 18). The protocol consisted three sets five repetitions...

Prolonged driving under real conditions can entail discomfort linked to posture, seat design features, and road properties like whole-body vibrations (WBV). This study evaluated the effect of three different seats (S 1 = soft; S 2 firm; 3 soft with suspension system) on driver’s sitting behavior perceived types in conditions. Twenty-one participants drove same 195 km itinerary alternating highway, city, country, mountain segments. Throughout sessions, Contact Pressure (CP), Surface (CS),...

ABSTRACT Background Abnormal cortical processing of sensory inputs has been found bilaterally in writer's cramp (WC). This study tested the hypothesis that patients with WC have an impaired ability to adjust grip forces according visual and somatosensory cues both hands. Methods A unimanual visuomotor force‐tracking task a bimanual sense effort force‐matching were performed by healthy controls. Results In tracking, showed increased error, greater variability, longer release duration than...

Purpose To investigate the beliefs of physiotherapy students (ST), professionals (PT) and physicians (MD) about engaging patients with post-stroke hemiparesis into Guided Self-Rehabilitation Contracts (GSC), to increase their exercise intensity responsibility level. Method A survey examining rehabilitation was completed by first (n = 95), second 105), third 48) year STs; PTs 129) MDs 65) in France. Results The belief whether a patient may alone varied between professional groups more STs...

The medial collateral ligament (MCL) is one of the most injured ligaments during sport activities. resulting joint damage effects on neuromuscular system remain unclear. Thus this study was designed to assess changes in properties vastus medialis muscle after MCL transection. Complete rupture performed rats, and dynamic functional assessment locomotion achieved before once a week from 1-5 wk postlesion. Twitch metabo- mechanosensitive afferent fiber responses specific stimuli were measured...

Medial collateral ligament (MCL) rupture of the knee joint frequently occurs during sport activities. However, optimal rehabilitation strategy after such lesion is unknown. The aim this study was to assess effects progressive eccentric program on neuromuscular deficits induced by MCL transection.Rats were randomized as follows: (i) control group (C, n = 10) without any surgery; (ii) groups in which measurements made 1 (L1, and 3 wk (L3, 9) transection a 15- 20-min surgery (this designed...

Background: Recent therapeutic and technological solutions aim to improve the daily living of people with limb amputation by considering various aspects phantom limb, in particular painless sensations (PS) voluntary movements (VPM). Objective: Although previous research has explored these phenomena mostly without prosthesis, this study investigates influence prosthesis wearing on PS, painful VPM, lower-limb amputation. Study Design: Cross-sectional based semi-directed interviews. Methods:...

Focal dystonia has been associated with deficient processing of sense effort cues. However, corresponding studies are lacking in cervical (CD). We hypothesized that dystonic muscle activity would perturb neck force control based on cues.Neck extension was investigated 18 CD patients different clinical features (7 and 11 without retrocollis) 19 subjects. Subjects performed force-matching force-maintaining tasks at 5% 20% maximum voluntary contraction (MVC). Three task conditions were tested:...

The aim of this study was to evaluate the reproducibility a protocol using inertial sensors in order characterize primary and associated movements head. Twenty-two subjects were evaluated twice same experimental conditions (3 days interval). Two allowed evaluation range movement Three complete cycles realised each plane. A patient suffering from cervical dystonia also with before after self-training program. Results show good for all ranges except sagittal Thereafter, our us notice an...

Conflicting results on the effects of occlusal proprioceptive information standing sway have been reported in literature, partly due to heterogeneity criterion studied and experimental protocol used. In this study, functions, different mandibular positions visual conditions were used investigate involvement proprioception static postural balance. Postural adjustments 26 healthy young adults, divided into Class I malocclusion normocclusion groups, upright position, five (1 free, 2 centric...
