BodybladeTM Training in Athletes with Traumatic Anterior Shoulder Instability

Background The BodybladeTM has the potential of enhancing conservative management of Traumatic Anterior Shoulder Instability (TASI). Purpose The purpose of this study was to compare three different protocols: Traditional, BodybladeTM, and Mixed (Traditional & BodybladeTM) for shoulder rehabilitation on athletes with TASI. Study Design Randomized-controlled longitudinal training study. Methods Thirty-seven athletes (age = 19.9 +/- 2.0 years) were allocated into Traditional, BodybladeTM, and Mixed (Traditional/BodybladeTM) training groups (3xweek for 8-weeks). The traditional group used resistance bands (10-15 repetitions). The BodybladeTM group transitioned from classic to the pro model (30-60-s repetitions). The mixed group converted from the traditional (weeks 1-4) to the BodybladeTM (weeks 5-8) protocol. Western Ontario Shoulder Index (WOSI) and the UQYBT were evaluated at baseline, mid-test, post-test, and at a three-month follow-up. A repeated-measures ANOVA design evaluated within and between-group differences. Results All three groups significantly (p=0.001, eta2: 0.496) exceeded WOSI baseline scores (at all timepoints) with training (Traditional: 45.6%, 59.4%, and 59.7%, BodybladeTM: 26.6%, 56.5%, and 58.4%, Mixed: 35.9%, 43.3% and 50.4% respectively). Additionally, there was a significant (p=0.001, eta2: 0.607) effect for time with mid-test, post-test and follow-up exceeding baseline scores by 35.2%, 53.2% and 43.7%, respectively. The Traditional and BodybladeTM groups (p=0.049, eta2: 0.130) exceeded the Mixed group UQYBT at post-test (8.4%) and at three-month follow-up (19.6%). A main effect (p=0.03, eta2: 0.241) for time indicated that WOSI mid-test, post-test and follow-up exceeded the baseline scores by 4.3%, 6.3% and 5.3%. Conclusions All three training groups improved their scores on the WOSI. The Traditional and BodybladeTM groups demonstrated significant improvements in UQYBT inferolateral reach scores at post-test and three-month follow-up compared to the Mixed group. These

Automated summary

This study compared three different protocols (Traditional, BodybladeTM, and Mixed) for shoulder rehabilitation on athletes with TASI. The results showed that all three training groups improved their scores on the WOSI and the Traditional and BodybladeTM groups demonstrated significant improvements in UQYBT scores.
