Abstract
BACKGROUND: Postural control deficits are prevalent in children with hemiplegic cerebral palsy (CwHCP). Therefore, the best rehabilitative strategies for remediating these deficits are warranted, which could then enhance function.
OBJECTIVE: To examine effects of a block versus an alternating sequence of balance training (BT) and plyometric training (PT) on postural control in CwHCP.
METHODS: Forty-eight CwHCP (812 years) were randomized to a block or an alternating BT/PT training. The block BT/PT group (n = 24) received a six-week BT followed by a six-week PT, twice/week over 12 consecutive weeks. The alternating BT/PT group (n = 24) received an interchanging sequence of BT and PT changed every two weeks for 12 weeks. Postural control [center-of-pressure reaction time (RT), movement velocity (MV), maximum excursion (ME), end-point excursion (EE), and directional control (DC)], functional balance (indicated by pediatric balance scale; PBS), and balance/risk-of-falls during walking (denoted by dynamic gait index; DGI) were assessed before and after training.
RESULTS: The block BT/PT group showed greater enhancements in postural control variables [RT (P = 0.004), MV (P = 0.028), ME (P = 0.002), EE (P = 0.003), and DC (P = 0.012)] and functional balance (P = 0.006), and lesser risk-of-falls during walking (P = 0.018) when compared to the alternating BT/PT group.
CONCLUSION: The block BT/PT sequence is more effective to enhance postural control than the alternating sequence in CwHCP.
