The study was designed to determine whether relationships exist among knee muscle spasticity, isometric knee muscle strength, knee muscle balance, gross motor function, and walking efficiency in children with spastic cerebral palsy and to evaluate the relative contributions of impairment measures to functional outcome measures. ⋯ Hamstring strength and quadriceps spasticity explain much of the variance in gross motor function and comfortable walking efficiency.
