INTRODUCTION: Oxidative stress, alpha-synuclein changes, mitochondrial complex I defects and dopamine loss, observed in the striatum of rats exposed to the pesticide permethrin in early life, could represent neuropathological hallmarks of Parkinson's disease (PD). Nevertheless, an animal model of PD should also fulfill criteria of face and predictive validities. This study was designed to: 1) verify dopaminergic status in the striatum and substantia nigra pars compacta; 2) recognize non-motor symptoms; 3) investigate the time-course development of motor disabilities; 4) assess L-Dopa effectiveness on motor symptoms in rats previously exposed to permethrin in early life...

OBJECTIVE: Postural balance is ensured by the involvement of several coping strategies. There is however an alteration of the proprioceptive system with chronic low back pain patients making it vulnerable to any type of disruptive force (endogenous and exogenous) and physiologically compensated by the postural system. The aim of this study is to measure the postural changes during a functional restoration protocol. MATERIAL/PATIENTS AND METHODS: Were included in this study, 8 chronic low back pain patients, seen in consultation before being included in the rehabilitative care unit of the Bourbonne-les-Bains Hospital as part of a functional restoration protocol for 5-6 weeks...

OBJECTIVE: The chronic lateral epicondylitis is a common pathology with an economic impact. Actually, many costly therapies are prescribed without evidence of their effectiveness. Physical therapies seem to be neglected. However, they can correct actions at risk and involve the patient in his rehabilitation. MATERIAL/PATIENTS AND METHODS: This study evaluated the effectiveness of a standardized 2 month rehabilitation program composed of: an outpatient group education session, 18 liberal physical therapy sessions with correction of the posture of the trunk and shoulder, eccentric strengthening of the supinator muscles and the wrist extensor muscles, stretching, and some self daily exercises (transverse friction massage and stretching) according to Pernot-Comtet protocol...

Sudden unilateral loss of vestibular function is the most severe condition that can occur in the vestibular system. The clinical syndrome is caused by the physiologic properties of the vestibulo-ocular reflex (VOR) arc. In the normal situation, the two peripheral vestibular end organs are connected to a functional unit in coplanar pairs of semicircular canals working in a push-pull mode. "Push-pull" mode means that, when one side is excited, the other side is inhibited, and vice versa due to two mechanisms...

CONTEXT: Both balance training and selected interventions meant to target sensory structures (STARS) have been shown to be effective at restoring deficits associated with chronic ankle instability (CAI). Clinicians often utilize multiple treatment modalities in patients with CAI. However, evidence for combined intervention effectiveness in CAI patients remains limited. OBJECTIVE: To determine if augmenting a balance training protocol with STARS (BTS) results in greater improvements than balance training (BT) alone in those with CAI...

PURPOSE: Total knee arthroplasty provides excellent results concerning functional demands, patient satisfaction and range of motion. Short-term results after implantation of patient-specific knee spacers also show encouraging results. We hypothesised that patient-specific interpositional devices provide better proprioception and postural stability by preserving the whole bone stock and both cruciate ligaments. METHODS: In this study we compared functional results, proprioception and postural stability 16 months after 20 consecutive patient-specific interpositional device implantations of the knee (group A) and 20 consecutive total knee arthroplasties (group B)...

AIM: To describe the surgical management and long-term outcome of a case of symptomatic residual acquired primary position excyclotropia, without changing the primary position vertical deviation. METHODS: This case report describes ipsilateral half tendon width transpositions of the left superior rectus temporally and inferior rectus nasally, combined with right inferior rectus posterior fixation suture at 11 mm. RESULTS: Three days postoperatively, the transposition procedure produced a 10° cyclotorsional change in primary position, resulting in 5° of incyclotorsion (double Maddox rod)...

BACKGROUND: Cervicogenic dizziness is a disabling condition commonly associated with cervical dysfunction. Although the growing interest with the importance of normal sagittal configuration of cervical spine, the missing component in the management of cervicogenic dizziness might be altered structural alignment of the cervical spinal region itself. AIM: To investigate the immediate and long-term effects of a 1-year multimodal program, with the addition of cervical lordosis restoration and anterior head translation (AHT) correction, on the severity of dizziness, disability, cervicocephalic kinesthetic sensibility, and cervical pain in patients with cervicogenic dizziness...

Karate is a martial art that partly depends on subjective scoring of complex movements. Principal component analysis (PCA)-based methods can identify the fundamental synergies (principal movements) of motor system, providing a quantitative global analysis of technique. In this study, we aimed at describing the fundamental multi-joint synergies of a karate performance, under the hypothesis that the latter are skilldependent; estimate karateka's experience level, expressed as years of practice. A motion capture system recorded traditional karate techniques of 10 professional and amateur karateka...

Rehabilitation of temporomandibular joint dysfunctions has for a long time tried to treat symptoms: pain relief, joint kinetics restoration, disk re-capture by manual maneuvers. The authors present their own therapeutic approach, which is no longer limited to symptoms, but addresses the causes and identifies risk factors to prevent relapse.

Physical, non-painful processes guide the scar reshaping in children in order to prevent growth anomalies due to cutaneous shrinkage. The objective of the surgical treatment, coordinated with the reeducation care, is to improve the physical abilities of the skin, to restore the function and avoid the deformations. Reeducation uses various techniques (i.e. sensitive-motility, massage and mobilizations) with or without physical agent (water, aspiration and touch-drive technique). Posture and positioning rely on the small or major aids, from orthosis to prosthesis...

Experimental studies have shown that a continuum of ankle and hip strategies is used to restore posture following an external perturbation. Postural responses can be modeled by feedback control with feedback gains that optimize a specific objective. On the one hand, feedback gains that minimize effort have been used to predict muscle activity during perturbed standing. On the other hand, hip and ankle strategies have been predicted by minimizing postural instability and deviation from upright posture. It remains unclear, however, whether and how effort minimization influences the selection of a specific postural response...

Yoga facilitates relaxation and connection of mind, body, and spirit through the use of breathing, meditation, and physical postures. Participation in yoga has been extensively linked to decreased stress, and as a result, is considered a therapeutic intervention by many. However, few theories exist that explain the link between yoga participation and improved psychosocial wellbeing. The leisure-stress coping conceptual framework suggests that through participation in leisure, an individual can decrease stress while concurrently restoring and building up sustainable mental and physical capacities...

BACKGROUND: Spinal sagittal imbalance is a widely acknowledged problem, but there is insufficient knowledge regarding its occurrence. In some patients with lumbar disc herniation (LDH), their symptom is similar to spinal sagittal imbalance. The aim of this study is to illustrate the spinopelvic sagittal characteristics and identity the role of spinal musculature in the mechanism of sagittal imbalance in patients with LDH. METHODS: Twenty-five adults with spinal sagittal imbalance who initially came to our clinic for treatment of LDH, followed by posterior discectomy were reviewed...

In our study, we examined postural stability during head turns for two rhesus monkeys: one animal study contrasted normal and mild bilateral vestibular ablation and a second animal study contrasted severe bilateral vestibular ablation with and without prosthetic stimulation. The monkeys freely stood, unrestrained on a balance platform and made voluntary head turns between visual targets. To quantify each animals' posture, motions of the head and trunk, as well as torque about the body's center of mass, were measured...

Ulnar nerve paralysis results in classic stigmata, including weakness of grasp and pinch, poorly coordinated flexion, and clawing of digits. Restoration of grasp is a key portion of the reconstructive efforts after loss of ulnar nerve function. Improving flexion at the metacarpophalangeal joint can be done by static and dynamic means, although only the latter can improve interphalangeal extension. Deformity and digital posture are more predictably corrected with surgical intervention. Loss of strength from intrinsic muscle paralysis cannot be fully restored with tendon transfer procedures...

In this paper, a neural networks (NNs) enhanced telerobot control system is designed and tested on a Baxter robot. Guaranteed performance of the telerobot control system is achieved at both kinematic and dynamic levels. At kinematic level, automatic collision avoidance is achieved by the control design at the kinematic level exploiting the joint space redundancy, thus the human operator would be able to only concentrate on motion of robot's end-effector without concern on possible collision. A posture restoration scheme is also integrated based on a simulated parallel system to enable the manipulator restore back to the natural posture in the absence of obstacles...
