Numerous studies have recently been published on improving upper-limb motor function after stroke. There has been a particular interest in brain stimulation techniques, which could promote brain plasticity. In this review, transcranial Direct Current Stimulation (tDCS) and repetitive Transcranial Magnetic Stimulation (rTMS) are presented as techniques that could be relevant in Physical Medicine and Rehabilitation (PM&R) centers in the future. We are presenting a comprehensive literature review on the studies using tDCS or rTMS for upper-limb rehabilitation after a stroke. Both techniques have shown their ability to modify cortical excitability and to transitorily improve upper-limb function after one single stimulation session. The first placebo-controlled, blinded therapeutic trials, which included repeated daily sessions, seem quite promising, and deserve to be validated by further trials.

This is a retrospective study of 39 male spinal cord injured patients who, over the last 5 years, have consulted us for ejaculatory dysfunction or infertility. All of these patients underwent at least two distinct sessions during which attempts were made to induce an ejaculation by vibratory stimulation, electric stimulation, or by using subcutaneous physostigmine. A semen analysis was performed each time that an ejaculate was obtained. By one or more of these techniques, 75% of these subjects were able to ejaculate. The level of the neurological lesion had a signi®cant in¯uence on the success rate. Likewise, the mode employed to produce an ejaculation in¯uenced certain characteristics of the sperm collected (mean volume, percentage of motile forms), the best results being obtained by vibratory stimulation. Among the 10 couples who had consulted us for medically assisted reproduction, three pregnancies were obtained, two of which resulted in the birth of healthy children. Although the techniques of stimulation that we use allow ejaculation, the possibilities of reproduction remain limited in particular because of the diculty in obtaining semen of adequate quality. Nevertheless, recent methods of micromanipulation of gametes should considerably improve the prognosis of the seminal insuciencies in men with spinal cord injury.

The protocol is managed as part of a local scheme and enables an appropriate response to a specific clinical profile by providing up-to-date multidiscipline follow-up care and a rapid solution should intercurrent events occur (signs of arousal, orthopedic deterioration, change of environment). Typical limitations are geographical remoteness and difficulties with family support care.

Abstract-The aim of this study was to analyze the displacements of center of pressure (COP) using an in-shoe recording system (F-Scan) before and after motor nerve block and neurotomy of the tibial nerve in spastic equinovarus foot. Thirty-nine patients (age 45 +/-15 yr) underwent a motor nerve block; 16 (age 38 +/-15.2 yr) had tibial neurotomy, combined with tendinous surgery (n = 9). The displacement of the COP (anteroposterior [AP], lateral deviation [LD], posterior margin [PM]) was compared between paretic and nonparetic limbs before and after block and surgery. At baseline, the nonparetic limb had a higher AP (17.3 vs 12.3 cm, p < 0.001) and LD (4.0 vs 3.3 cm, p = 0.001) and a smaller PM (2.9 vs 4.7 cm, p = 0.001). For the paretic limb, a significant increase of AP was observed after block (13.5 vs 12.3 cm, p = 0.02) and after surgery (13.7 vs 12.3 cm, p = 0.03). A significant decrease of PM was observed after surgery (4.5 vs 3.3 cm, p < 0.001) with no more difference between two limbs (2.8 vs 3.3 cm, p = 0.44). This study shows that the F-Scan system can be used to quantify impairments and be useful to evaluate the effects of treatment for spastic foot. It suggests that changes in AP displacement following block may predict the effects of neurotomy.
