Abstract
- Equinus in hemiplegic children is multifactorial. In some cases it is due to a short muscle, in others to simple foot-drop, tonic spasticity, rigidity, compensation for a short limb, fixed flexion contracture at the hip, dominantly inherited forefoot deformity, forefoot equinus secondary to chronic toe-walking, or abnormalities of the visco-elastic properties of the muscle, with true intramuscular contracture. This neurophysiological study confirms that hemiplegia in children is not a homogeneous condition. Some have tonic spasticity; some, although stiff, show electrical silence on stretching; some appear to have a short muscle, with no hypertonicity; and others have hypertonicity in relation to position (i.e. rigidity). A short muscle is not always associated with tonic spasticity with reciprocal inhibition. Weakness can occur without spasticity. Speed of movement of toes, ankle and hip is also significantly reduced.
