AIM: To investigate the relation between muscle endurance and subjectively
reported fatigue, walking capacity, and participation in mildly affected
adolescents with cerebral palsy (CP) and peers with typical development. METHOD:
In this case-control study, knee extensor muscle endurance was estimated from
individual load-endurance curves as the load corresponding to a 15-repetition
maximum in 17 adolescents with spastic CP (six males, 11 females; age 12-19y) and
18 adolescents with typical development (eight males, 10 females; age 13-19y).
Questionnaires were used to assess subjectively reported fatigue (Pediatric
Quality of Life Inventory Multidimensional Fatigue Scale) and participation
(Life-Habits questionnaire). Walking capacity was assessed using the 6-minute
walk test. Relations were determined using multiple regression analyses. RESULTS:
Muscle endurance related significantly to subjectively reported fatigue and
walking capacity in adolescents with CP, while no relations were found for
adolescents with typical development (subjectively reported fatigue: regression
coefficient beta [95% confidence intervals] for CP=23.72 [6.26 to 41.18], for
controls=2.72 [-10.26 to 15.69]; walking capacity beta for CP=125m [-87 to 337],
for controls=2m [-86 to 89]). The 15-repetition maximum did not relate to
participation in adolescents with CP. INTERPRETATION: Subjectively reported
fatigue and reduced walking capacity in adolescents with CP are partly caused by
lower muscle endurance of knee extensors. Training of muscle endurance might
contribute to reducing the experience of fatigue and improving walking capacity.
Reduced muscle endurance seems to have no effect on participation.
