Abstract
A functional evaluation of 350 hip joints in patients who had undergone hip-joint surgery was carried out, and the correlation between activity of daily living (ADL) and range of motion (ROM) was analyzed. Of the assessment categories adopted by the Japan Orthopedic Association, the 5 activities of ‘cutting of nails’, ‘putting on and removing of socks’, ‘bowing from the kneeling position’, ‘standing up’ and ‘crouching’ showed a strong association with ROM. Flexion, abduction and internal rotation were found to be related to ADL at a ratio of 6 to 4 to 4.
The degree of difficulty in ADL was divided into 5 levels, and the angle required (movement limits) in each of these was investigated. It is possible to deduce the range of motion required once the ADL is evaluated, and a functional evaluation of the hip joint can be made even without direct examination. Furthermore, a hip-joint functional evaluation standard (I, II) was devised in consideration of the Japanese living style and housing situation.
