1. The results of the sensory examination of the hands of ninety-six children with cerebral palsy are presented. Sensory disorders were found in forty of the ninety-six patients (41.7 per cent).
2. The most common sensory defects in order of their frequency were: astereognosis, impairment of two-point discrimination and position sense. In addition to these, some patients failed to distinguish numbers traced lightly on the skin and were deficient in weighing perception, localization of tactile stimuli, sharp and dull discrimination, hot and cold discrimination, and in length measurement.
3. The practical significance of the above findings in orthopaedics is discussed.
