Study summary

There has been much effort in recent years to better understand the causes of idiopathic scoliosis (IS). Some studies suggested muscle imbalance as a cause of scoliosis based on asymmetric muscular activation. Surface electromyography can evaluate asymmetrical muscular weakness. Therefore, the peak amplitude values can be used to compare the side to side differences in paraspinal muscles. From these findings the investigators improve the exercise method of IS according to muscle weakness and curve pattern.

Read the detailed description

Design: Prospective study Setting: hospital rehabilitation department the investigators will check the muscular activation at bilateral paraspinal muscles with surface electromyography and curve type with simple radiography.

Intervention: After that the investigators educate asymmetrical stabilization exercise according to muscle weakness and curve pattern.

Main outcome measures: Cobb angle

What researchers measure

Primary outcomes

  1. Cobb angle

    the angle of curvature be measured by drawing lines parallel to the upper border of the upper vertebral body and the lower border of the lowest vertebra of the structural curve on plain radiography

    Time frame: through study completion, an average of 6 months

Secondary outcomes

  1. Scoliosis Research Society-22(SRS-22)

    questionnaire for evaluating quality of life in patients with idiopathic scoliosis

    Time frame: through study completion, an average of 6 months

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 Dec 2016 to primary completion in Nov 2017, 10 months.

Of 5,147 non-industry interventional studies with no phase under Motor Activity, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 36. This study's 10 months is below that.

Counting every sponsor, half of 5,207 studies reached it within 17 months; a quarter within 7 and three quarters within 36.

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 Jul 22, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
