Exercise and manual physiotherapy arthritis research trial (EMPART) for osteoarthritis of the hip: a multicenter randomized controlled trial.

OBJECTIVES: To determine the effectiveness of exercise therapy (ET) compared with ET with adjunctive manual therapy (MT) for people with hip osteoarthritis (OA); and to identify if immediate commencement of treatment (ET or ET+MT) was more beneficial than a 9-week waiting period for either intervention. DESIGN: Assessor-blind randomized controlled trial with a 9-week and 18-week follow-up. SETTING: Four academic teaching hospitals in Dublin, Ireland. PARTICIPANTS: Patients (N=131) with hip OA recruited from general practitioners, rheumatologists, orthopedic surgeons, and other hospital consultants were randomized to 1 of 3 groups: ET (n=45), ET+MT (n=43), and waitlist controls (n=43). INTERVENTIONS: Participants in both the ET and ET+MT groups received up to 8 treatments over 8 weeks. Control group participants were rerandomized into either ET or ET+MT groups after 9 week follow-up. Their data were pooled with original treatment group data: ET (n=66) and ET+MT (n=65). MAIN OUTCOME MEASURES: The primary outcome was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) physical function (PF) subscale. Secondary outcomes included physical performance, pain severity, hip range of motion (ROM), anxiety/depression, quality of life, medication usage, patient-perceived change, and patient satisfaction. RESULTS: There was no significant difference in WOMAC PF between the ET (n=66) and ET+MT (n=65) groups at 9 weeks (mean difference, .09; 95% confidence interval [CI] -2.93 to 3.11) or 18 weeks (mean difference, .42; 95% CI, -4.41 to 5.25), or between other outcomes, except patient satisfaction with outcomes, which was higher in the ET+MT group (P=.02). Improvements in WOMAC, hip ROM, and patient-perceived change occurred in both treatment groups compared with the control group. CONCLUSIONS: Self-reported function, hip ROM, and patient-perceived improvement occurred after an 8-week program of ET for patients with OA of the hip. MT as an adjunct to exercise provided no further benefit, except for higher patient satisfaction with outcome.

High incidence of osteoporosis and fractures in an aging post-polio population.

BACKGROUND/AIMS: Since the polio epidemic in Ireland in the 1950s, most polio survivors are approaching into the 6th and 7th decade of their lives. There is little data about bone density and risk of fractures in these patients. In 2006, we undertook an audit of post-polio patients attending rheumatology and neurology outpatient clinics in a university teaching hospital. Our aim was to determine the prevalence of osteoporosis (OP), falls and fractures and to evaluate the association of bone density with other potential contributing factors to OP. METHODS: Over a 6-month period, 50 post-polio patients attending outpatient clinics completed a questionnaire, and subsequently their medical records were reviewed. Demographic data and details of treatment were extracted. The patients underwent a dual-energy X-ray absorptiometry scanning to quantify bone mineral density. RESULTS: Thirty subjects (60%) were females (26 were postmenopausal). The average age of females was 60 +/- 13.4 years and of men 59 +/- 16.8 years. Overall, 41 (82%) of the patients had experienced falls in the last 5 years and 32 (64%) in the last 6 months. Nineteen (38%) of the patients had experienced a bone fracture in the last 5 years. Based on the bone mineral density data, 28 (56%) of the patients were diagnosed with OP and 20 (40%) had osteopenia, but only 8 (16%) received anti-resorptive therapy. Of the 19 patients who had a fracture, 14 (74%) had OP and 5 (26%) had osteopenia, of whom only 6 (32%) received anti-resorptive therapy. Eight out of 9 fractures of the neck of femur occurred in the weaker leg. CONCLUSIONS: Post-polio patients are a high-risk group for fracture, and thus bone density assessment, review of falls risk and therapeutic intervention should be considered for all patients. Both osteopenia and OP are associated with increased fracture risk.
