Thesis Abstract
Osteoarthritis (OA) is a prevalent degenerative joint condition among older adults, significantly contributing to impaired balance and increased risk of falls, which compromise independence and quality of life. Despite the widespread use of traditional physiotherapeutic interventions, there remains a pressing need to explore alternative and adjunctive therapies that can effectively improve postural stability in this population. This study aims to evaluate the effects of aquatic therapy on balance among older adults with osteoarthritis, with particular focus on functional balance, fear of falling, and quality of life. The specific objectives are to determine the extent to which aquatic therapy improves postural control; examine changes in participants’ fear of falling post-intervention; and assess the impact of aquatic therapy on overall quality of life. A quasi-experimental research design with pre-test and post-test control groups will be employed. The target population comprises community-dwelling adults aged 60–75 years diagnosed with osteoarthritis of the knee or hip, attending outpatient physiotherapy clinics in metropolitan healthcare facilities. A total sample of 80 participants will be recruited through stratified random sampling, with 40 assigned to the intervention group receiving aquatic therapy and 40 to the control group receiving standard land-based physiotherapy. Data collection instruments include the Berg Balance Scale (BBS) for objective balance assessment, the Falls Efficacy Scale-International (FES-I) for fear of falling, and the Short Form-36 (SF-36) health survey for quality of life metrics. The validity and reliability of these instruments are well-established in geriatric populations with osteoarthritis. Data will be analyzed using descriptive statistics to summarize baseline characteristics. Inferential analysis will involve paired t-tests to assess within-group changes, independent t-tests to compare intervention effects between groups, and repeated measures ANOVA to evaluate differences over time. Regression analyses will explore predictors of balance improvement, while effect sizes will be calculated to determine clinical significance. The study will be grounded in Bandura’s Self-Efficacy Theory, providing a framework for understanding how aquatic therapy may enhance confidence and motor control in balance tasks. It is anticipated that findings will demonstrate significant improvements in balance scores among participants undergoing aquatic therapy, alongside reductions in fear of falling and enhancements in health-related quality of life. These outcomes are expected to support the hypothesis that aquatic therapy, due to its low-impact and resistance properties, effectively facilitates neuromuscular adaptations necessary for postural stability in older adults with osteoarthritis. The results will contribute to the growing body of empirical evidence advocating for integrative physiotherapeutic approaches that incorporate aquatic environments. The main conclusion will emphasize the efficacy of aquatic therapy as a safe, accessible, and efficacious modality for improving balance in this demographic, thereby potentially reducing fall risk and enhancing functional independence. The study will recommend the integration of aquatic therapy into routine rehabilitation protocols for older osteoarthritis patients and suggest pathways for further research into long-term adherence and cost-effectiveness. Overall, this research aims to inform clinical practice, influence policy development in geriatric physiotherapy, and foster multidisciplinary approaches to managing balance impairments associated with osteoarthritis in aging populations.
Thesis Overview
This research investigates how aquatic therapy influences balance in older adults with osteoarthritis, a common joint condition that causes pain, stiffness, and difficulty moving. Balance problems are frequent in people with osteoarthritis, increasing their risk of falls and injury. While exercise is known to help improve balance, not all types are equally effective or suitable for everyone. Aquatic therapy, which involves exercising in water, offers unique benefits because water reduces joint stress and provides resistance, making movement easier and safer. This study aims to determine whether participating in aquatic therapy can significantly improve balance compared to traditional land-based exercises.
The research addresses a gap in knowledge about the specific effects of aquatic therapy on balance in this population, helping clinicians make better-informed treatment choices. The study will follow a step-by-step approach. First, a sample of around 60 older adults diagnosed with osteoarthritis will be recruited and randomly assigned to either an aquatic therapy group or a land-based exercise group. Data on their balance will be collected before and after an 8-week intervention period using standardized tools like the Berg Balance Scale and Timed Up and Go test. During the intervention, participants will attend supervised training sessions three times a week.
Data analysis will involve comparing pre- and post-intervention scores within and between groups using statistical methods like paired t-tests and analysis of variance (ANOVA). This will reveal whether aquatic therapy produces significant improvements in balance compared to land exercises. The study also aims to explore if certain subgroups benefit more than others, based on factors like age or severity of osteoarthritis.
The expected contribution of this research is providing evidence-based insights into the effectiveness of aquatic therapy for balance improvement in older adults with osteoarthritis. The findings could support the development of tailored exercise programs and promote safer, more comfortable options for managing balance problems in this population. Overall, the study expects to show that aquatic therapy is a valuable, safe, and effective way to enhance balance and reduce fall risk among older adults with osteoarthritis.
