Description
Introduction:
Muscle power has shown to be positively correlated to functional walking capacity and more impaired than muscle strength and in children with cerebral palsy (CP). We hypothesize that Power Training combined with interval Treadmill Training (PT³) will significantly improve muscle performance in children with CP compared to traditional Strength Training and Traditional Locomotor Treadmill Training (STT).
Purpose:
The purpose of this secondary analysis was to compare the specificity of training effects of PT³ and STT on peak torque and power produced across the force-velocity spectrum.
Methods:
Thirty-eight children with CP participated in this study (mean age 13.5 ± 2.4 years; range 10-17 years; 20 male, 18 female; GMFCS level I=10, II=24, III=4). Participants were randomized to either 8 weeks of STT (n = 18) or an equal dosage of PT3 (n = 20). Isokinetic dynamometry at 30, 60, 90 and 120 deg/s was used to assess knee extensor peak torque and average power at baseline, postintervention, at 2-mo and 6-mo post intervention. Change relative to baseline was used for statistical analysis.
Results:
No between-group differences were observed in peak torque and average power across speeds. Significant within-group increases in average power were observed after PT3 for 60deg/s at 2- mo post (p = 0.04) and at 6-mo post-intervention for 90 and 120deg/s (p = 0.03). Significant increases in peak torque at 120deg/s were also observed after PT3 at 6 mo post intervention (p = 0.02).
Discussion:
Results suggests that a combined intervention approach targeting muscle power deficits specifically improves muscle performance in children with CP with better retention of effects at 6 months post intervention compared to STT.
