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 equal 10) and control group (C; n equal 9), the mean (plus or minus SD) age for all participants was 59 plus or minus 12 years. They were recruited from outpatient physiotherapy clinics, had persistent pain located at the hip joint for more than 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 more or equal 20 points or more or equal 50 percent 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 to 100). The mean (range) treatments received were 13 (7 to 16) over 5 to 12 weeks and 20 (18 to 24) over 12 weeks for E and C, respectively. The experimental group showed superior clinical post-treatment effect on HOOS (more or equal 20 points), in six of 10 participants compared with none of nine in the control group (p equal 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.
