Conditions
Brief summary
Osteoarthritis of the hip is a common chronic condition that affects the health and wellbeing of New Zealanders with approximately 7000 people undergoing hip joint replacement per year. This pilot study will examine the feasibility and effectiveness of implementing an exercise programme for patients awaiting hip replacement (prehabilitation). It will also investigate whether ultrasound can be used as a reliable tool to assess hip muscle volume, a modifiable parameter with potential as an outcome measure.
Interventions
The intervention will be a multi-modal exercise programme adapted from the exercise therapy protocol used in the Management of Osteoarthritis Trial (Australian New Zealand Clinical Trials Registry ACTRN12608000130369). The programme includes lower limb strengthening (with additional specific exercises that target the hip abductor muscles) and stretching exercises, neuromuscular retraining (focusing on balance) and core stability exercises. The exercises will be delivered in a group setting (lead
The intervention will be a multi-modal exercise programme adapted from the exercise therapy protocol used in the Management of Osteoarthritis Trial (Australian New Zealand Clinical Trials Registry ACTRN12608000130369). The programme includes lower limb strengthening (with additional specific exercises that target the hip abductor muscles) and stretching exercises, neuromuscular retraining (focusing on balance) and core stability exercises. The exercises will be delivered in a group setting (lead by a physiotherapist), but will be individually-tailored according to the abilities and impairments of each patient. The group sessions for each cohort of participants in the Intervention Group (6 in each, 12 in total) will be held twice a week in an exercise laboratory at the School of Physiotherapy, University of Otago. These will run over an 8-week period, and each session will last for approximately an hour. A log will be kept of attendance/completion of the prescribed group exercise sessions. Participants in the intervention group will also receive an individualised home exercise programme to do on the days they do not attend class, which will take approximately 30 minutes. Participants will also be provided with a calendar log to document adherence to the home exercise programme, use of analgesics and any adverse treatment responses (e.g. such as an increase in hip pain). Any adverse reactions occurring during the exercise classes will also be documented. Those assigned to the Control Group will not receive the intervention but continue with usual care.
