Abbreviations: SD, standard deviation; CI, confidence interval; MPT, movement pattern training group; HOOS, Hip Disability and Osteoarthritis Outcome Score; HOOSADL, function in activities of daily living; HOOSSport, function in sports and recreation; HOOSQOL, quality of life; ABDs, abductors with the hip abducted 15°; ERs90°, external rotator strength with hip in 90° flexion; ERs0°, external rotator strength with hip in neutral flexion/extension.
Change is calculated by subtracting the pretest value from the posttest value.
Adjusted treatment effects are calculated by subtracting the MPT minus Wait-list.
Patient-reported outcome measures with 100=no disability.
P value by analysis of covariance (ANCOVA).
Adjusted treatment effects and p-values are reported at the two pretest levels which discriminate between group differences that are and are not statistically significant.
Muscle torque (Nm) was normalized by body weight (N) × height (m) × 100.
