Abstract
Purpose: To develop a reliable and feasible isokinetic fatigue protocol for the knee flexors and extensors in individuals with cerebral palsy (CP) who are ambulatory.
Methods: Twelve subjects with CP, 10 to 23 years old, participated in the study. The protocol consisted of repeated maximum voluntary concentric knee flexion and extensions at 60°/sec for a minimum of 35 repetitions. Fatigue Index (FI) and slope of the linear regression were computed. Reliability tests conducted a week later with five of the 12 subjects. Intraclass correlation coefficients were calculated for test–retest reliability.
Results: All subjects completed 35 repetitions, with only half reaching a 50% decline. All fatigue parameters were reliable for both knee flexors and extensors (slope: 0.94 and 0.97; slope/peak torque: 0.83 and 0.99; FI: 0.73 and 0.86, respectively).
Conclusions: This isokinetic fatigue protocol is reliable and feasible for children and young adults with mild to moderate CP.
