the Tone and Viscoelastic Properties of Back Muscles in Thoracic Kyphosis
A study testing exercises in people with Exercise and Kyphosis, run by Sanko University at 1 site in Turkey (Türkiye).
Trial summary
The thoracic curvature of the spinal column occurs in the sagittal plane. While the normal thoracic kyphosis angle of the spine is 20-40°, an angle of 45-50° is referred to as postural kyphosis, increased kyphosis, or hyperkyphosis. Read more about this study

About this study
Official title: The Effect of an 8-Week Corrective Exercise Programme on the Tone and Viscoelastic Properties of Back Muscles in Thoracic Kyphosis
The thoracic curvature of the spinal column occurs in the sagittal plane. While the normal thoracic kyphosis angle of the spine is 20-40°, an angle of 45-50° is referred to as postural kyphosis, increased kyphosis, or hyperkyphosis. The strength of the central and deep back muscles of the trunk controls spinal stability and intervertebral movements in dynamic situations. This ensures that thoracic curvature is maintained within normal physiological limits.
Increased kyphosis can result from poor postural habits, prolonged computer use, trunk asymmetry, and muscle weakness. Studies have reported an increase in thoracic kyphosis, postural deviations in the trunk, and changes in shoulder and head positions as a result of weakening of the back muscles. Corrective exercise programmes aimed at strengthening the back muscles are frequently used in the treatment of thoracic kyphosis. The effects of exercise programmes on muscle strength, endurance, and kyphosis angle have been investigated. However, there are few studies examining the effects of corrective exercise programmes on muscle tone and viscoelastic properties in the back muscles. In our study, we aim to investigate the effects of an 8-week corrective exercise programme on the tone and viscoelastic properties of the back muscles in individuals with thoracic kyphosis and to propose its inclusion as a contemporary approach in clinical treatment protocols.

What is being measured
The primary outcome is the main question the study is designed to answer.
The MyotonPro
device can determine the stiffness, tone, and elasticity properties of muscles. This previously calibrated device creates a mechanical stimulus that induces the damped natural oscillations of the tissues using a 3 mm diameter probe placed perpendicular to the muscle with a non-invasive handheld feature. The resulting oscillations are recorded by an accelerometer. MyotonPro® is a valid and reliable method for determining muscle tone, stiffness, and elasticity, and it also offers high test-retest reliability and reproducibility .
Measured: 8 weeks
Flexible Ruler:
The flexible ruler method is a reliable method used to measure cervical, thoracic, and lumbar spine curvature. The measurement is taken using a 40 cm long flexible ruler while standing with arms relaxed at the sides, head upright, and eyes looking straight ahead. The C2 and C7 vertebrae are palpated and marked using removable adhesive skin markers. The flexible ruler is then placed over the cervical lordosis between these two points, and markers indicating the location of the C2 and C7 spinous processes are placed on it. The flexible ruler is placed on millimeter paper, and the resulting curve is reflected. A vertical angle is drawn from the peak of the curve to the baseline, and the cervical lordosis deviation angle is determined using an angle-to-angle connection
Measured: 8 weeks
Kyphosis-Specific Spine Appearance Questionnaire
The Kyphosis-Specific Spine Appearance Questionnaire consisted of 10 items on a Likert scale (1 to 5) regarding patients' perceptions of appearance; higher scores indicated worsening deformity and increased concern about kyphosis-specific appearance. The first item is based on drawings showing varying degrees of severity of hyperkyphosis deformity in the sagittal plane. Questions two through ten are based on textual questions that rate concerns about other aspects of spinal deformity appearance. The total score of the questionnaire is calculated as the average of the ten responses
Measured: 8 weeks
