Effects of a late-phase exercise program after total hip arthroplasty: a randomized controlled trial

Area of Science:

• Orthopedics
• Rehabilitation Medicine
• Gerontology

Background:

• Total hip arthroplasty (THA) is a common procedure for hip joint dysfunction.
• Patients often experience residual functional deficits months after THA.
• Late-phase rehabilitation strategies are crucial for optimizing recovery post-THA.

Purpose of the Study:

• To evaluate the efficacy of a late-phase, home-based exercise program for individuals 4 to 12 months post-THA.
• To assess the impact of targeted exercises on muscle strength, postural stability, and self-perceived function.

Main Methods:

• A single-blind, randomized controlled trial involving 34 adults 4-12 months post-THA.
• Participants were randomized into an experimental group (strength and postural stability exercises) or a control group (basic exercises).
• Intervention lasted 8 weeks, with outcomes measured pre- and post-trial.

Main Results:

• The experimental group showed significant improvements in self-perceived function, hip flexor, extensor, abductor strength, knee extensor strength, and postural stability.
• Muscle strength gains ranged from 23.4% to 47.8%, and postural stability improved by 36.8%.
• No significant changes in fear of falling were observed in either group.

Conclusions:

• An 8-week exercise program focusing on weight-bearing and postural stability effectively enhances muscle strength, postural stability, and function in the late phase after THA.
• This intervention offers a viable approach to further improve outcomes for THA patients.
