Abstract
Background and Aims: Despite extensive studies on hyper kyphosis posture, many questions remain about its etiology and contributing factors. So far, most previous studies have focused on elderly females. The contributing factors to hyper kyphosis in males have not been well studied. The aim of the present study is to compare the back extensor muscle force and endurance, and ability to regenerate the sense of force of these muscles in elderly males with and without hyperkyphosis posture
Materials and Methods: This is a protocol study of a cross-sectional study on 70 elderly males aged 60 to 80 years. After dividing the participants into two equal groups with (n=35) and without (n=35) thoracic hyper kyphosis posture, the force, endurance, and error of reconstruction of the force sense of the back extensor muscles will be measured and compared between the two groups. Thoracic kyphosis will be assessed using a flexible ruler and the function of the back extensor muscles will be assessed using a S-shaped load cell device. According to data distribution, an Independent t-test or Mann-Whitney test will be used to determine differences in variables between two groups. A Pearson or Spearman analysis will be used to investigate the adjusted associations of the variables of the back extensor function variables and thoracic kyphosis.
