![]() ![]() Osteoarthritis, Range of motion, Disability In both knee and hip OA patients, flexion of the knee and extension and external rotation of the hip were found to be most closely associated with disability.Ĭonclusion. Restricted joint mobility, especially in flexion of the knee and extension and external rotation of the hip, appears to be an important determinant of disability in patients with OA. Some 25% of the variation in disability levels could be accounted for by differences in ROM. Low ROMs were associated with high levels of disability, both self‐reported and observed. ![]() Results. Close inter‐relationships were found between the ROMs of the same joint action of the lateral and contralateral joints inter‐relationships between ROMs of different joint actions were substantially weaker. Correlation and multiple regression analyses were carried out to establish the relationships between ROM and disability. Correlation and factor analysis were used to establish the inter‐relationships between the ROMs of joint actions. Disability was assessed using a self‐reporting method (questionnaire) and an observational method. The ROM was assessed bilaterally for the hip and knee, using a goniometer. Methods. Data on 198 patients with OA of the knee or hip were used. ![]() Two related issues were addressed: (1) the inter‐relationships between ROMs of joint actions, and (2) the relationship between ROM and disability. Objective. To establish the relationships between the range of joint motion (ROM) and disability in patients with osteoarthritis (OA) of the knee or hip. ![]()
