The effects of progressive resistive exercises on strength and dexterity of the hand of persons with cerebral palsy

Background and Aim: Cerebral palsy (CP) is a common disorder in human society with many somatosensory problems that affects on functional capability. Dexterity affects activity of daily activity. The aim of this study was to investigate the effects of Progressive resistive exercises on strength and dexterity of cerebral palsy persons. Materials and Methods: Twelve CP persons between 8 to 16 years old (10 boys and 2 girls) with mean age of 11.9 years old participated in this study. Progressive resistive exercises (PRE) protocols were done on upper extremity of study group 3 times a week for 6 weeks. Strength of shoulder abductors and extensors were evaluated by MMT NICHOLAS apparatus. Grip strength and dexterity were evaluated by Jammar Dynammometer and Purdue peg board respectively. Results: Shoulder abductors and extensors strength increased %29.4 (p=0.0001) and %30.1 (p=0.014). Grip strength and dexterity improved %9.8 (p=0.048) and dexterity %23 (p= 0.016) respectively. Conclusion: PRE increase muscle strength of upper extremity and may improve dexterity in children with cerebral palsy.
