Superior effect of forceful compared with standard traction mobilizations in hip disability?
THE OBJECTIVE OF THIS STUDY WAS TO COMPARE THE EFFECTIVENESS OF TWO COMPILED PHYSIOTHERAPY PROGRAMS: one including forceful traction mobilizations, the other including traction with unknown force, in patients with hip disability according to ICF (the International Classification of Functioning, Disability and Health, 2001; WHO), using a block randomized, controlled trial with two parallel treatment groups in a regular private outpatient physiotherapy practice. In the experimental group (E; n = 10) and control group (C; n = 9), the mean (+/-SD) age for all participants was 59 +/- 12 years. They were recruited from outpatient physiotherapy clinics, had persistent pain located at the hip joint for >8 weeks and hip hypomobility. Both groups received exercise, information and manual traction mobilization. In E, the traction force was progressed to 800 N, whereas in C it was unknown. Major outcome measure was the median total change score >/=20 points or >/=50% of the disease- and joint-specific Hip disability and Osteoarthritis Outcome Score (HOOS), compiled of Pain, Stiffness, Function and Hip-related quality of life (ranging 0-100). The mean (range) treatments received were 13 (7-16) over 5-12 weeks and 20 (18-24) over 12 weeks for E and C, respectively. The experimental group showed superior clinical post-treatment effect on HOOS (>/=20 points), in six of 10 participants compared with none of nine in the control group (p = 0.011). The effect size was 1.1. The results suggest that a compiled physiotherapy program including forceful traction mobilizations are short-term effective in reducing self-rated hip disability in primary healthcare. The long-term effect is to be documented.
