Upper Limb Botulinum Toxin Injection Combined With Self Rehabilitation

The patients in the self-rehabilitation group will be taught the self-rehabilitation program by a physiotherapist who is not involved in the patient follow-up. They will receive a log book which will be used to evaluate compliance and tolerance to the program. They will be instructed to carry out the exercises 7 days per week for the whole duration of the study and to record which exercises they carried out and for how long, after each exercise session.
