Abstract
Background and Aim: Development of outcome measures remains a focus of health research in the 21st century. Outcome measures originally developed for the Nigerian environment are very rare. The aims of this study were to develop an outcome measure for management of hip and knee arthritic conditions, and to investigate the validity and responsiveness of it. Methods: The Ibadan Knee/Hip Osteoarthritis Measure (IKHOAM)was developed from other measures found in literature, as well as complaints of attending patients. Forty nine patients with pain from knee and/or hip osteoarthritis, the OA group (OAG) and 49 individuals without knee or hip pain, the pain-free group (PFG) were assessed, using the IKHOAM. The OAG was assessed on IKHOAM and the Visual Analogue Scale (VAS) before and after a 6-week physiotherapy programme. Results: Significant differences between IKHOAM scores of the OAG and PFG and between IKHOAM scores of OAG pre and post 6-week physiotherapy programme, as well as the significant negative correlations between changes in IKHOAM and VAS scores of OAG before and after the 6-week physiotherapy programme were demonstrated. Conclusion: IKHOAM demonstrated initial criteria towards validity and responsiveness and may be used in a Nigerian population of OA knee/hip individuals and similar environments.
Highlights
Osteoarthritis is a common chronic joint disease and a leading cause of disability in the elderly (Swedberg and Steinbauer, 1992)
We observed that some of the existing osteoarthritis outcome measures include few items such as “turning faucets off and on” and “walking several blocks” which may not be readily understood by Nigerians, especially those with low educational attainments
On the basis of all these, we embarked on developing an outcome measure for knee and hip osteoarthritis that would be both patient- and clinicianadministered and would be appropriate for the Nigerian environment
Summary
Osteoarthritis is a common chronic joint disease and a leading cause of disability in the elderly (Swedberg and Steinbauer, 1992). It affects 60-70% of the Western adult population older than 60 years (Lane, 1997). Many generic and disease-specific outcome measures have been developed Many of these clinical instruments measure what matters most to patients and the payers, that is, the change in the functional health status (Yeomans, 2000). On the basis of all these, we embarked on developing an outcome measure for knee and hip osteoarthritis that would be both patient- and clinicianadministered and would be appropriate for the Nigerian environment. The OAG was assessed on IKHOAM and the Visual Analogue Scale (VAS) before and after a 6-week physiotherapy programme
