Outcome Measures
Primary Outcomes (3)
Percentage of Participants With Acceptable GSM In-Brace Correction
Acceptable GSM in-brace correction was defined as a difference of 10 degrees or less between the TLSO and GSM in-brace Cobb angles.
Baseline (TLSO measurement) to GSM brace delivery (GSM measurement) within 60 days
Percentage of Participants With Curve Stability or Progression at 3-month Follow-up
Curve stability is defined as progression of 10 degrees or less between the Cobb angle at baseline and at follow-up after GSM wear (Baseline Cobb angle minus follow-up Cobb angle).
Baseline to ~3 mo Follow-up
Unanticipated Adverse Events
Unanticipated adverse events associated with the GSM brace and patient characteristics likely to raise safety issues
Up to 1 year
Secondary Outcomes (3)
Change in Brace-related Quality of Life Scores (Brace Questionnaire)
Baseline to Visit 3 (3-4 months post-baseline)
Change in Quality of Life Scores
Baseline to Visit 3 (3-4 months post-baseline)
Difference in Vital Capacity Measured in TLSO and GSM Brace
Baseline
Study Arms (1)
Green Sun Dynamic Brace
EXPERIMENTALHistorical measures of brace effectiveness (in- and out-of-brace Cobb angles), wear time, and brace-related quality of life will be compared to those measured after the subject is fit with a Green Sun dynamic brace.

Limitations and Caveats
1. Enrollment and data collection was interrupted by COVID (e.g. spirometry testing was suspended) 2. Of the 11 subjects who did not complete the 30 day visit (\>75 days of follow-up), 6 were among the first 10 subjects enrolled.The GSM brace underwent design and materials changes during the trial, especially during the evaluation of the first 10 subjects. 3. One study site shut down before all subjects had finished the protocol, resulting in missing data (n=2)
