Phantom hand and wrist movements in upper limb amputees are slow but naturally controlled movements.

After limb amputation, patients often wake up with a vivid perception of the presence of the missing limb, called "phantom limb". Phantom limbs have mostly been studied with respect to pain sensation. But patients can experience many other phantom sensations, including voluntary movements. The goal of the present study was to quantify phantom movement kinematics and relate these to intact limb kinematics and to the time elapsed since amputation. Six upper arm and two forearm amputees with various delays since amputation (6months to 32years) performed phantom finger, hand and wrist movements at self-chosen comfortable velocities. The kinematics of the phantom movements was indirectly obtained via the intact limb that synchronously mimicked the phantom limb movements, using a Cyberglove® for measuring finger movements and an inertial measurement unit for wrist movements. Results show that the execution of phantom movements is perceived as "natural" but effortful. The types of phantom movements that can be performed are variable between the patients but they could all perform thumb flexion/extension and global hand opening/closure. Finger extension movements appeared to be 24% faster than finger flexion movements. Neither the number of types of phantom movements that can be executed nor the kinematic characteristics were related to the elapsed time since amputation, highlighting the persistence of post-amputation neural adaptation. We hypothesize that the perceived slowness of phantom movements is related to altered proprioceptive feedback that cannot be recalibrated by lack of visual feedback during phantom movement execution.

[Rehabilitation following primary repair of flexor tendons in adults]. / Rééducation après réparation primaire des tendons fléchisseurs des doigts chez l'adulte.

Rehabilitation after primary repair of flexor tendons, particularly in the early phase, has changed due to more solid suture repairs. The objectives of this article are to outline the general principles surrounding this rehabilitation, set out the indications for various early mobilization techniques and describe in detail the physiotherapy protocol used by the Physical Medicine and Rehabilitation Department of the Regional Institute of Rehabilitation in collaboration with the Plastic and Reconstructive Surgery Department of the Émile-Gallé Surgical Center in Nancy, France. This protocol is mainly used for adult patients and carried out in four stages over a 12-week period. If there are no contraindications, the patient learns protected early active self-rehabilitation during the first four postoperative weeks. The protocol includes standardized multidisciplinary follow-up until the social and occupational rehabilitation phase to ensure the best chance of functional recovery.

[Rehabilitation after secondary surgery of the flexor tendons of fingers and thumb]. / Rééducation après chirurgie secondaire des tendons fléchisseurs des doigts.

The repair of the finger flexor tendons can be complicated by the appearance of ruptures and peritendinous adhesions. Ruptures are often treated with tendon grafts. Peritendinous adhesions can require tenolysis. Following these two surgical procedures, there is a risk of new adhesions and rupture. Rehabilitation after this secondary surgery consists of a tailored, closely supervised protocol. Protocols used by the team at the Physical Medicine and Rehabilitation Department of the Regional Rehabilitation Institute and the team at the Plastic and Reconstructive Surgery Department of the Emile-Gallé Surgical Center of Nancy (France) are described. A close collaboration between these teams of surgeons and physical therapists is essential. After tendon grafting, protected early motion helps to move the transplant immediately while still protecting it. After tenolysis, immediate (several times a day) and extended rehabilitation ensures that the mobility obtained intraoperatively is maintained. It is performed in a specialized rehabilitation center during the first three postoperative weeks. The goal is to prevent new adhesions from forming while taking into account tendon's fragility.

Suprascapular nerve entrapment in a patient with a spinal cord injury.

STUDY DESIGN: Case report. OBJECTIVES: To describe a case of suprascapular nerve entrapment (SNE) in a patient with a spinal cord injury (SCI) as a cause of shoulder pain. SETTING: Physical Medicine and Rehabilitation Institute, Nancy, France. REPORT: Six months after the occurrence of acute paraplegia T9 ASIA, a 45-year-old man complained of pain in the posterior and lateral areas of the left shoulder. A clinical assessment found an atrophy of the infraspinatus muscle and a muscular weakness during external shoulder rotation. SNE was suggested as a cause of pain and confirmed by nerve conduction recording. Magnetic resonance imaging excluded any compressive cyst. SNE at the spinoglenoid notch, related to upper limb overuse, was suggested. A gluco-corticoid injection in the proximity of the suprascapular nerve eliminated the pain in a few hours. Two months after the injection, the pain had not reappeared, the infraspinatus muscle atrophy was resolved, and supraspinal nerve conduction was normalized. CONCLUSION: Shoulder pain is common in individuals with paraplegia, but this is the first time that SNE has been reported as a cause of pain. This micro-traumatic pathology, well known in athletes, is probably under-diagnosed in patients with SCI who overuse their upper limbs for wheelchair propulsion and body transfers.

Assessment of compliance with prescribed activity by hemiplegic stroke patients after an exercise programme and physical activity education.

UNLABELLED: Although post-stroke exercise training programmes improve aerobic capacity and functional capacities in the short-term, the impact on exercise performance at home has not been established. OBJECTIVES: To assess compliance with prescribed physical activity by hemiplegic stroke patients. To compare the patients' stated activity with their actual activity. PATIENTS AND METHODS: This was a prospective pilot study of nine hemiplegic patients following an exercise training programme. Each patient's activity was measured using an activity monitor (the ActivPAL) before, during and immediately after the programme and then 3months after the end of the programme. The activity actually performed was compared with the levels recommended after a stroke (at least 30minutes of non-stop activity three times a week). Three months after the end of the programme, the patient's stated and actual activities (in terms of frequency and duration) were compared. RESULTS: Activity patterns changed immediately after the end of the programme. Short-term compliance was good for four patients. However, 3months later, only one patient was performing regular activity in accordance with the guidelines. Hence, medium-term compliance was poor. Most patients overestimated both the duration and frequency of their activity sessions. CONCLUSION: Three months after the end of the supervised training programme, compliance with physical activity guidelines was low. The ActivPAL activity monitor is easy to use and performs satisfactorily. It can be used as a tool for activity assessment and education intervention. The use of an actimeter may increase the efficacy of health education interventions, which promote physical activity.
