About
This study was set out to evaluate the effect of a 12-week upper extremity plyometric exercise (Plyo-Ex) on muscle strength and upper extremity function in children with hemiparetic cerebral palsy (Hemi-CP). Fifty-eight children with Hemi-CP were randomly allocated to the Plyo-Ex group (n = 29, received Plyo-Ex program, twice/week, over 12 weeks) or the control group (n = 29, received standard exercise program). Both groups were assessed for muscle strength and upper extremity function before and after treatment.
Full description
Fifty-eight children with Hemi-CP were recruited from the Physical Therapy Outpatient Clinic of Prince Sattam Bin Abdulaziz University and three referral hospitals in Riyadh provenience, Saudi Arabia. Their age ranged between 10 and 15 years, were functioning at levels I or II according to the Gross Motor Function Classification System, and had spasticity levels 1 or 1+ per the Modified Ashworth Scale. Children were excluded if they had fixed deformities, underwent neuromuscular or orthopedic surgery in the last 12 months, submitted to BOTOX injection in the past 6 months, had attentional neglect, demonstrated any cognitive issues, and if they had cardiopulmonary problems that could be exacerbated by exercise.
Outcome measures
Muscle strength: The peak isometric muscle strength of the shoulder flexors, abductors, external rotators, elbow extensors, and wrist extensors was measured using a hand-held dynamometer.
Unilateral upper-extremity function : The unimanual functional performance was assessed using Melbourne Assessment (MA).
Bimanual hand function:The biimanual functional performance was evaluated utilizing the Assisting Hand Assessment (AHA)
The Plyo-Ex group received a 12-week therapist-led Plyo-Ex training, for approximately 45 minutes per session, two times a week for 12 consecutive weeks, in conformity with the National Strength and Conditioning Association guidelines and American Academy of Pediatrics safety standards. The Plyo-Ex program consisted of ten unilateral and bilateral upper extremity exercises in the form of push-ups and ball slams/throws/passes activities. The Plyo-Ex program preceded with a warm-up for 5 minutes and ended with a cool-down for 5 minutes. The control group received the standard exercise program, 45 minutes per session, two times a week for 12 consecutive weeks. The program consisted of flexibility exercises, strength training, weight-bearing exercises, proprioceptive neuromuscular facilitation, coordination exercise, task-oriented training, and functional exercises.
