Exercise interventions, physical function, and mobility after hip fracture: a systematic review and meta-analysis

Area of Science:

• Gerontology
• Rehabilitation Medicine
• Exercise Physiology

Background:

• Hip fractures are a common and serious injury in older adults, often leading to significant declines in physical function and mobility.
• Effective rehabilitation strategies are crucial for improving outcomes and restoring independence after hip fracture.

Purpose of the Study:

• To evaluate the impact of various exercise components on physical function and mobility in adults following a hip fracture.
• To identify the most effective exercise interventions for post-hip fracture rehabilitation.

Main Methods:

• A systematic review and meta-analysis of randomized controlled trials.
• Searches were conducted across major databases including PubMed, Embase, Cochrane Library, Web of Science, CINAHL, and PsycINFO up to March 2021.
• Included studies focused on exercise interventions for adults after hip fracture, assessing physical function and mobility outcomes.

Main Results:

• Exercise interventions demonstrated a moderate positive effect on overall physical function (SMD = 0.46).
• Progressive resistance exercise yielded the largest effect on physical function (SMD = 0.48), with loads of 60-80% 1RM.
• Exercise showed a small positive effect on mobility (SMD = 0.28), with functional exercise being particularly effective (SMD = 0.41).

Conclusions:

• Exercise interventions are effective in improving physical function and mobility in older adults post-hip fracture.
• Progressive resistance exercise (60-80% 1RM) and functional exercise are critical components for rehabilitation.
• Supervised exercise by healthcare professionals is recommended for optimal benefits.
