Background and study aims
Osteoarthritis (OA) is the most common type of arthritis, which most often affects the knee. It occurs when the protective cartilage on the end of bones wears away. The bones then rub against one another, which can cause stiffness, pain and a reduction in a person’s range of movement. Osteoarthritis of the hip (hip OA) is very common, especially in older adults. It can be very painful and if severe, it can make walking very difficult. In these cases, hip replacement surgery (in which the hip joint is replaced using an artificial joint) is the only treatment which is able to help people to regain mobility without suffering from debilitating pain. Many studies have shown that after undergoing hip replacement surgery, exercise is an important part of recovery and the process of regaining mobility. This study is looking at adding an extra set of arm and upper body exercises to the current physical exercise programme used after this type of surgery. The aim of this study is to find out how effective adding the extra exercises to the standard rehabilitation programme compared to the standard rehabilitation programme alone.
Who can participate?
Adults aged 60 and over with severe hip OA who have been admitted for hip replacement surgery at Zvezdara University Hospital.
What does the study involve?
Following surgery, participants are randomly allocated to one of two groups. Those in the first group take part in the standard rehabilitation programme. This involves taking part in 30 minute exercise sessions twice a day, five days a week, for two weeks in hospital, then supervised in the inpatient rehabilitation center (for four weeks) and unsupervised at home (for six weeks) starting the day after surgery. The sessions involve a set of exercises to improve range of motion, muscle strength of the legs, as well as leg function, balance, coordination and gait (way of walking) with weight bearing. Those in the second group also take part in the standard rehabilitation programme but also take part in additional arm and upper body exercises. This comprises of 15 minutes added to each standard exercise session involving physical chair exercises for arm and upper body, with/out resistance and with regular, deep breathing for improvement of patients’ posture, flexibility, and range of motion and the muscle strength of the arms. Participants in both groups undergo a range of assessments at the start of the study and again after 12 weeks in order to find out if their mobility and muscle strength has improved. Participants also complete a questionnaire at these times in order to find out if their quality of life has improved.
What are the possible benefits and risks of participating?
Benefits of taking part in the additional exercises group include improvements to muscle strength, physical ability for daily activities and quality of life. There are no notable risks involved with taking part in this study.

| Scientific title | The effectiveness of supplementary arm and upper body exercises to the standard rehabilitation programme following total hip arthroplasty for osteoarthritis in the elderly |
| Study objectives | Both groups will improve on all outcome measures after a three month exercise programme and the group with the supplementary exercises would have significantly more improvements on all outcome measures compared with the standard exercise group. |
| Ethics approval(s) | Research Ethics Boards both at the “Zvezdara” University Hospital and Belgrade Faculty of Medicine, 29/05/2011, ref: 29/V-17 |
| Health condition(s) or problem(s) studied | Hip osteoarthritis |
| Intervention | Participants are randomised to one of two groups, and begin their physical rehabilitation one day post-operatively. A randomization sequence is created using a computer-generated list of random nubers block sizes of four. Control group: The standard rehabilitation programme lasts 30 minutes and consists of exercises to improve joint range of motion and muscle strength lower limbs, function, balance, coordination and gait with weight bearing from day one and was performed twice a day, five days a week, for two weeks in hospital, after that supervised in inpatient rehabilitation center ( for four weeks) and unsupervised at home (for six weeks). Intervention group: Participants also take part in the standard rehabilitation program but with additional upper limb and body exercises, adding 15 minutes to the sessions. The additional exercises involve additional physical chair exercises for arm and upper body, with/out resistance, in order to improve posture, flexibility and muscle strength and to implement regular, deep breathing. Participants are assessed at baseline (one day pre-operatively), after the intervention (two weeks postoperatively) and at three months follow-up (12 weeks postoperatively). The first two assessments are done while participants are in hospital and the last one is planned and scheduled as an outpatient check-up. |
| Intervention type | Behavioural |
| Primary outcome measure | Change in the hip function and physical performance of the lower limbs is measured using the Harris Hip score (HHS) at baseline, two weeks and three months postoperatively. |
| Secondary outcome measures | 1. Muscle strength measured by Hand grip strength (HGS) at baseline, two weeks and three months postoperatively 2. Health-related quality of life measured by Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) at baseline, two weeks and three months postoperatively Added 19/12/2016: 3. Functional status is assessed by the New Mobility Score Modified (NMSMod) at baseline, two weeks and three months postoperatively |
