An interventional study of Singapore Youth Shoulder Overuse Injury Prevention Program and Lower body stretching program in Sport Injury, sponsored by Nanyang Technological University. Not yet recruiting at 1 site in Singapore. Open to participants aged 12 Years to 18 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-02-22.

The Singapore Youth Shoulder Overuse Injury Prevention Program (YoSO-IPP) includes an exercise segment and an education segment. This study will (1) assess the effects of the exercise segment, and (2) assess the effects of the education segment among youth volleyball athletes using a randomized controlled trial over 12 weeks. Performance outcome measures of shoulder eccentric external rotation strength, shoulder internal rotation range of motion, and thoracic rotation range of motion will be used to assess the effects of the exercise segment. Knowledge scores via an online questionnaire will be used to assess the effects of the education segment.
Hypothesis: The YoSO-IPP will have an effect on shoulder eccentric external rotation strength, shoulder internal rotation range of motion, and thoracic rotation range of motion and on knowledge scores.
A randomized controlled trial study design will be utilized to assess the effects of YoSO-IPP over 12 weeks. A within-team randomization will be conducted. This is to ensure a good balance between the intervention and control groups as different teams have different training regimes, training frequencies and training intensities.
Participants in the intervention group will be required to perform the exercise segment of YoSO-IPP for 12 weeks, at a recommended frequency of two times per week - (a) cross-body stretch, (b) eccentric external rotation shoulder strength exercise, (c) trunk rotation, and (d) modified cat-cow thoracic mobility exercise.
Participants in the control group will be required to perform lower body stretches for 12 weeks, at a recommended frequency of two times per week - (a) double leg calf stretch, (b) quadriceps stretch, (c) hip flexor stretch, (d) seated single leg hamstring stretch, and (e) seated single gluteal stretch. This stretching program is considered a sham program in this study as it does not target the upper extremity and the stretches are only held for 10 seconds.
Participants in both groups will each receive an instruction booklet for their respective program. Respective instructional videos will also be distributed. For the following 12 weeks, participants are to perform the exercises at a recommended frequency of two times per week. They will also be required to report the number of times they performed their respective programs that week via an online questionnaire weekly.
Participants who are randomized into the intervention group will attend an online 45-minute educational workshop in Week 1. This is the education segment of YoSO-IPP. Participants who are randomized into the control group will not attend the online 45-minute educational workshop.

Exclusion Criteria:
Participants will be instructed to perform YoSO-IPP at a recommended frequency of two times per week for 12 weeks and attend an online 45-minute educational workshop in Week 1
Other: Singapore Youth Shoulder Overuse Injury Prevention Program
Participants will be instructed to perform the lower body stretching program at a recommended frequency of two times per week.
Other: Lower body stretching program
A 10-minute, 4-exercises program that targets shoulder eccentric external rotation strength, shoulder internal rotation range of morion, and thoracic rotation range of motion. The topic for the 45-minute educational workshop will be on overuse injuries among youth athletes.
A 10-minute, 5-stretches sham exercise program that does not target the upper extremity and are only held for 10 seconds.
Shoulder external rotation strength
Shoulder external rotation strength is a performance outcome measure of interest. It will be measured using a handheld electronic dynamometer. It will be presented in Newtons (N).
Time frame: Baseline (Week 0), Week 6, Week 12
Internal rotation range of motion
Shoulder internal rotation range of motion is a performance outcome measure of interest. It will be measured using 'Clinometer', a validated phone application for range of motion measurement. It will be presented in degrees (°).
Time frame: Baseline (Week 0), Week 6, Week 12
Thoracic rotation range of motion
Thoracic rotation range of motion is a performance outcome measure of interest. It will be measured using 'Clinometer', a validated phone application for range of motion measurement. It will be presented in degrees (°).
Time frame: Baseline (Week 0), Week 6, Week 12
Knowledge of overuse injuries
Knowledge scores will be calculated based on a novel questionnaire concerning youth athletes and overuse injuries. The scores will range from 0 to 20, with higher scores indicating a better outcome.
Time frame: Baseline (Week 0), Week 12
Shoulder overuse injury prevalence
Injury prevalence will be determined based on the Youth Overuse Injury Questionnaire (YOvIQ).
Time frame: Baseline (Week 0), Week 12
Elbow overuse injury prevalence
Injury prevalence will be determined based on the Youth Overuse Injury Questionnaire (YOvIQ).
Time frame: Baseline (Week 0), Week 12
Shoulder overuse injury severity
Injury severity will be determined based on the Youth Overuse Injury Questionnaire (YOvIQ). Severity score will range from 0 to 100, with higher scores indicating a more severe injury.
Time frame: Baseline (Week 0), Week 12
Elbow overuse injury severity
Injury severity will be determined based on the Youth Overuse Injury Questionnaire (YOvIQ). Severity score will range from 0 to 100, with higher scores indicating a more severe injury.
Time frame: Baseline (Week 0), Week 12
