the Tone and Viscoelastic Properties of Back Muscles in Thoracic Kyphosis

An interventional study of exercises in Exercise and Kyphosis, sponsored by Sanko University. Completed at 1 site in Turkey (Türkiye). Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2026-08-07.

Registry
Motor Activity — the first condition term the registry derived for this study.

Kyphosis
Why
  1. Motor Activity is a broad heading, used only when no more specific condition is named.
  2. The study's listed conditions name Kyphosis.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study 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. 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 researchers measure

Primary outcomes

  1. 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 .

    Time frame: 8 weeks

  2. 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

    Time frame: 8 weeks

  3. 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

    Time frame: 8 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Apr 2025 to primary completion in Jun 2026, 14 months.

Of 56 non-industry interventional studies with no phase under Kyphosis, half reached primary completion within 9 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 30. This study's 14 months is above that.

Counting every sponsor, half of 58 studies reached it within 9 months; a quarter within 4 and three quarters within 30.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 7, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
