Effects of Three Different Exercise Programs on Dynamic Balance in Community-Dwelling Older Adults: A Randomized Controlled Trial

Обзор

This study aims to compare the effects of core stabilization exercises, an amplitude-based exercise program derived from LSVT BIG principles, and their combination on dynamic balance in community-dwelling healthy older adults aged 65 years and above. Secondary outcomes include functional mobility, fear of falling, reaction time, and quality of life. Age-related declines in neuromuscular and sensory functions impair postural control and increase fall risk. While both core stabilization and amplitude-based exercises have shown beneficial effects, their comparative and combined effects in healthy older adults remain unclear. This study will determine whether the combined intervention provides additional benefits over single interventions.

Подробное описание

Aging is associated with progressive declines in muscle strength, proprioceptive function, vestibular efficiency, and reaction time, all of which contribute to impaired postural control and reduced dynamic balance. These changes significantly increase the risk of falls in older adults, representing a major public health concern due to their association with morbidity, mortality, and loss of independence.

Exercise-based interventions are widely recommended to improve balance and reduce fall risk. Core stabilization exercises aim to enhance trunk muscle activation and improve postural control by increasing spinal stability. In contrast, amplitude-based exercise approaches derived from LSVT BIG principles focus on increasing movement amplitude, thereby improving motor performance and functional mobility. Although both approaches have demonstrated beneficial effects, evidence regarding their comparative effectiveness and the potential additive benefit of combining these interventions in healthy older adults remains limited.

In this randomized controlled study, participants aged 65 years and older will be allocated to one of three intervention groups: core stabilization exercises, amplitude-based exercises based on LSVT BIG principles, or a combined core and amplitude-based exercise program. All interventions will be conducted over a structured training period under supervision.

Dynamic balance will be assessed as the primary outcome. Secondary outcomes will include functional mobility, fear of falling, reaction time, and quality of life. Standardized and validated assessment tools will be used to ensure reliability of the measurements.

The findings of this study are expected to provide evidence on the relative and combined effectiveness of these exercise approaches and may contribute to the development of more effective rehabilitation strategies aimed at improving balance and reducing fall risk in older adults.
