The overall functional gain by balance rehabilitation after hip fracture surgery has not yet been fully investigated. Therefore, clinical studies should be conducted to evaluate the effectiveness of systematic and safe balance rehabilitation in patients after hip fracture. Investigators aim to evaluate the effect of computer-based balance specific exercise on the performance and balance ability of the elderly women who underwent hip fracture surgery. Investigators also investigate the intervention can reduce their fear of falling and coping ability. This study was designed as a prospective, open-label, single-center trial at a tertiary hospital setting. During the 2-week postoperative intervention period, patients will participate in the hospital's exercise program beginning 5-7 days after hip fracture surgery. All participants will follow the computer-based balance specific exercise program. Functional outcomes will be measure periodically for 6 months after surgery.

Inclusion Criteria:
