Comparison of the effectiveness of novel intervention on restricted range of motion of shoulder in young healthy subjects

OBJECTIVE: To evaluate the effectiveness of four novel and pragmatic interventions on the restricted range of motion (ROM) of shoulder joint in healthy subjects. METHODS: The study was conducted at Helping Hand Institute of Rehabilitation Sciences, Mansehra, in 6-months duration. This quasi-experimental study recruited 120 young subjects with an equal proportion of males and females for four novel intervention groups (n=30 each group) including pragmatic posterior capsular stretch, Serratus anterior stretch, rotator cuff facilitation and acromioclavicular joint mobilization. Study variables included measurement of Reaching up behind the back (RUBTB), Reaching down behind the neck (RDBTN), and shoulder range of motion (flexion, abduction, external rotation, internal rotation). The paired t-test was used for the change in pretest and posttest variables and the Kruskal Wallis test was used to compare the change in each group of interventions. RESULTS: All the variables improved significantly (p< 0.05) from their baseline scores for the interventions. The mean difference among the intervention groups for the variables was statistically significant (p<0.001) on the Kruskal Wallis test. Pragmatic posterior capsular stretch (PPCS) and serratus anterior stretch (SAS) improved the RUBTB and RDBTN more than the other interventions. Rotator cuff facilitation (RFC) improved shoulder rotation more than the rest of the intervention. Acromioclavicular joint mobilization (ACJM) was effective in improving the abduction and flexion ROM. CONCLUSION: Pragmatic interventions are effective in improving shoulder ROM in young healthy adults and recommended for the trials on prevention and rehabilitation of shoulder pathologies.
