Objectives: Reduced range of motion, as a consequence of the muscle and connective tissue stiffness has been shown to associate with higher incidence of falling in elderly. Some investigations have indicated that reduced hip and the ankle range of motions, constitutes one of the main causes of fall due to their influence on walking pattern. This study examined the impact of an eight–week hip and ankle stretching program in elderly`s balance.

Methods & Materials: Through this experimental, case-control, single blind and clinical trial design,30 volunteers based on inclusion and exclusion criteria and after obtaining informed consents, were selected randomly and assigned into two intervention and control groups. The intervention group received a hip and ankle flexibility program for both lower extremities three times per week over a period of 8 weeks, and control group participants maintained activity level for 8 weeks. Hip and ankle range of motion assessed by a standard goniometry and balance level was measured by berg balance score. All participants were assessed a week and eight weeks post intervention one week before and after the eight week training period. Independent and paired t- test were used to analyze differences within groups.

Results: Compared with the control group, the intervention group had increased hip extension and ankle dorsi-flexion motion and Berg balance score (P<0.001).

Conclusion: Findings suggest joint range of motion and balance, can be effectively promoted with flexibility training in elderly.
