The Clinical Effectiveness of Progressive Resistance Training With Elastic Band in Postponing and Preventing Sarcopenia Among Older Adults in Rural Long-Term Care Facilities

Обзор

The goal of this clinical trial is to evaluate the effectiveness of progressive resistance training using elastic bands in treating and delaying the progression of sarcopenia among older adults in long-term care facilities. Sarcopenia, characterized by a progressive decline in muscle mass and strength, affects more than 20% of individuals aged over 65 in Taiwan and is a significant risk factor for impaired daily functioning, falls, and increased mortality in older adults. While resistance or aerobic exercises are known to improve muscle strength and function in the elderly, such interventions are challenging to implement long-term in rural care facilities due to limited resources. The study aims to determine: Whether elastic band progressive resistance training can achieve clinical benefits in treating and delaying sarcopenia with minimal rehabilitation personnel. Whether this training model can be adapted to rural care facilities and other resource-limited settings, aligning with the goals of Taiwan's Long-Term Care 2.0 program. Participants will engage in a 12-week program, involving twice-weekly, 30-minute sessions of upper and lower limb resistance training using elastic bands. The training incorporates major muscle groups and proprioceptive neuromuscular facilitation (PNF) techniques. Primary outcomes: Skeletal muscle mass index of the limbs Dominant hand grip strength Walking speed SARC-F questionnaire scores Secondary outcomes: Maximal voluntary isometric contraction (MVIC) of the dominant hand Muscle thickness assessed via ultrasound Functional activities of the dominant upper limb Calf circumference Quality of life indicators The study will be conducted in long-term care facilities affiliated with or contracted by the Ministry of Health and Welfare Qishan Hospital. The findings aim to provide evidence for scalable, low-resource sarcopenia interventions suitable for rural and underserved populations.

Подробное описание

Study Objectives Sarcopenia is a progressive condition characterized by the loss of muscle mass and decline in muscle function. The prevalence of sarcopenia in the elderly population aged over 65 years in Taiwan exceeds 20%. Sarcopenia is an independent risk factor for impaired daily functioning, falls, and increased mortality among older adults. Previous studies have demonstrated that resistance or aerobic exercise can improve muscle strength and functionality in the elderly. However, due to manpower constraints, such exercise programs are challenging to implement long-term in rural care facilities. Therefore, a simple and safe resistance training model that minimizes the risk of exercise-related injuries in older populations is needed.

Previous research has shown that progressive resistance training using elastic bands can effectively enhance muscle strength in older adults under safe conditions while reducing the risk of bone and joint injuries associated with traditional resistance training. However, the efficacy of elastic band training in delaying the progression of sarcopenia and determining the optimal exercise prescription for the elderly remain contentious.

This study aims to implement progressive resistance training using elastic bands for the upper and lower limbs of older adults in long-term care facilities to achieve the following expected outcomes:

Demonstrate that progressive resistance training using elastic bands can provide clinical benefits in treating and delaying sarcopenia with minimal rehabilitation personnel, while minimizing the risk of exercise-related injuries.

Apply the findings to rural daycare centers and other facilities with limited manpower resources, aligning with the goals of Taiwan's current Long-Term Care 2.0 program.

Study Methods This study will be conducted in long-term care facilities affiliated with or contracted by the Ministry of Health and Welfare Qishan Hospital, including nursing homes and daycare centers. Older adults with sufficient cognitive function to participate in rehabilitation exercises will undergo a 12-week intervention of progressive resistance training using elastic bands, performed twice per week. The training will target major muscle groups of the upper and lower limbs and incorporate proprioceptive neuromuscular facilitation (PNF) techniques. Each session will last 30 minutes.

The differences in primary and secondary outcomes will be compared before and after the intervention.

Primary outcomes include diagnostic criteria for sarcopenia: appendicular skeletal muscle mass index, dominant hand grip strength, walking speed, and SARC-F questionnaire scores.

Secondary outcomes include maximal voluntary isometric contraction (MVIC) of the dominant hand, muscle thickness assessed via ultrasound, functional activities of the dominant upper limb, calf circumference, and quality of life indicators.

Вмешательства

• Устройство elastic band
  Participants in the experimental group will receive standard care plus progressive resistance training with elastic band (PRT-EB). The PRT-EB is planned to last for 12 weeks, with at least two sessions per week and a minimum interval of one day between sessions. Before each training session, participants will perform a 5-15-minute warm-up exercise led by the research staff. This will be followed by a 30-minute main rehabilitation exercise program and a subsequent 5-15-minute cool-down session.
