Objectives: The purpose of this study was to investigate correlation between functional mobility with balance and dependency in activity of daily living in elderly after “hip arthroplasty” (HA) and its comparison with healthy subjects.

Methods & Materials: The current cross-sectional study was done on 15 patients with age mean and standard deviation (72±9.6) with hip osteoarthritis 6 months after “hip arthroplasty” (HA) and 15 healthy subjects with age mean and standard deviation (72.7±1.4) as control group. Patient group was assigned with non- probability convenient sampling and control group selected with matched assignment. Functional mobility measured with Timed Up & Go Test (TUG), functional balance with Functional Reach (FR) and Berg Balance Scale (BBS) and dependency in activity of daily living measured with Modified Barthel Index (MBI). Pearsons correlation coefficient used for stastistical analysis.

Results: Results of this study indicated significantly and stronge correlation between functional mobility and balance and dependency in activity of daily living in patient group (r>0.50). Also medium correlation existed between functional mobility and balance with dependency in activity of daily living in control group (r>0.30).

Conclusion: Functional mobility and balance and dependency in activity of daily living in the elderly who had HA showed significant positive correlation. In addition correlation between functional mobility and balance and dependency in activity of daily living in patient group is better and higher than healthy group.
