Abstract
Background and Aims Postural changes caused by aging severely affect the functional abilities of older adults. One of the common postural abnormalities in older adults is increased thoracic kyphosis or hyperkyphosis. To determine the contributing factors of hyperkyphosis in older men, the present study aims to compare the back extensor muscles’ strength, endurance, and ability to regenerate the sense of force of these muscles between older men with and without hyperkyphosis.
Methods This is a protocol study with a cross-sectional design that will be conducted in spring and summer of 2025 on 70 Iranian older men aged 60-80 years. After dividing them into two groups with hyperkyphosis (n=35) and without hyperkyphosis (n=35), the strength, endurance, and error in regeneration of back extensor muscles’ sense of force will be measured and compared between them. Independent t-test or Mann-Whitney U test will be used to determine the differences in study variables between the two groups. Pearson’s or Spearman’s correlation test will be used to investigate the adjusted associations of the back extensor function variables and thoracic kyphosis.
