RESUMO
To identify and compare the [two joint muscles] mechanics of spastic cerebral palsies and to manipulate the [two joint muscles] mechanics to improve gait quality in spastic CPs. Nine Spastic CPs, [two males and seven females, of mean age 4.9 years], were studied, following the categorical selection criteria. The therapeutic regimen was reinforced by, [specific muscle reeducation techniques] focusing to inhibit the abnormal synergism. The spastics had higher stiffness due to the primary impairments [muscle tone/ movement patterns, distribution, balance etc.], differences in the landing angles of feet due to secondary impairments [ROM, joint alignment, force production, etc.] and higher energy requirements. Interventions to enhance outcomes were positively correlated. The potential determinants of motor change in two joint muscles could assist in the functional performance with regard to gait and posture. Biochemical studies on energy requirements in CPs are recommended
