Segal (2012) Tolerance of an Aquatic Power Training Program by Older Adults with Symptomatic Knee Osteoarthritis

Introduction to Aquatic Power Training

Aquatic power training has emerged as a promising rehabilitation approach for older adults experiencing symptomatic knee osteoarthritis (OA), a condition that significantly hampers mobility and quality of life. Recognizing the limitations imposed by knee OA, including pain and reduced muscle power, this study by Neil A. Segal and Robert Wallace explores the feasibility and efficacy of an aquatic power training program tailored for this demographic.

Study Design and Implementation

The study involved 29 participants over the age of 50, all of whom exhibited symptomatic knee OA and mobility limitations. Participants engaged in a 6-week aquatic power training regimen, consisting of twice-weekly 45-minute sessions designed to enhance lower limb muscle power and alleviate OA symptoms.

Findings and Implications

Results demonstrated a significant improvement in participants’ lower limb muscle power, ADL, and overall QOL immediately following the program and persisting for 6 weeks post-completion. However, notable enhancements in walk times and lower limb function were not observed, suggesting the program’s specific benefits without broadly addressing all aspects of physical function. These findings underline the potential of aquatic power training as a viable and well-tolerated intervention for older adults with knee OA, offering meaningful improvements in symptoms and daily functioning.

Conclusion and Future Directions

The study concludes that aquatic power training presents a beneficial and sustainable rehabilitation option for older adults with symptomatic knee OA, specifically in improving muscle power, pain management, and QOL. Future research should focus on expanding these findings, possibly incorporating control groups and exploring the integration of aquatic training with other rehabilitation modalities to optimize outcomes for this population.
