Shortening in Achilles tendon is one of the most common complications in spastic hemiplegic cerebral palsy. The present study was conducted to determine the effect of Electromyographic feedback stimulation during two weeks immobilization period after tendo-Achilles lengthening in children with spastic hemiplegic cerebral palsy. Thirty children with spastic hemiplegic cerebral palsy, ranges from seven to nine years in age (x` 8.2430±0.863yr.), represented the sample of the study. They were selected from different hospitals in Cairo, Egypt. The peak torque of ankle dorsiflexors and ankle excursion were measured via using MERAC isokinetic system and electro-gonimeter respectively. The subjects were divided randomly into two groups, Group A (control) received Electromyographic feedback stimulation after removal of plaster cast for two weeks daily in addition to designed physical therapy program, while Group B (study) received Electromyographic feedback stimulation during immobilization period (two weeks) in addition to the same program of Group A. Evaluation for each child of the two groups was conducted immediately after removal of plaster cast and then after two weeks. The results of this study revealed significant improvement in peak torque of ankle dorsiflexors and ankle excursion in favour of group B; also, a significant difference was observed in the results of the two groups immediately after removal of the cast in favour of group B. Improvement occurred in the measuring variables of groups b may be attributed to the effect of Electromyographic feedback stimulation during immobilization which resulted in strengthening in the anterior tibial muscles group which helped in maintain the obtained range of ankle dorsiflexion and preventing the recurrence of tendo-Achilles shortening.

Several studies have shown a strong relationship between cohesion and performance. According to Carron & al. (2002), the team’s definition will not be victorious. Moreover, Carron (1998) defined the cohesion of a team as “a dynamic process reflected in the tendency of the members of a group to remain close to each other and to remain united in the pursuit of its Objectives and / or satisfaction of their emotional needs “. The publications in the Field of the sciences of the sport is relative to the situations, so-called “collective” remain numerous and well located. They find an anchoring essentially in social psychology on the phenomena of group, from which they derive the methods. They are translated into sport around concepts that revolve mainly around the concepts of “cohesion” (under the impetus of Widemeyer, 1985, and Carron, 1982), and of “leadership” (Chelladurai, 1990). Indeed, there is no such thing as soldering a group to be attached together, in the primary sense of the term, and thus be able to take up a challenge that requires both to surpass itself and to show solidarity, all in a setting outside Of the common, for an unusual purpose.
