Unilateral seated shot-put test, muscle strength, and range of motion on recreational athletes with chronic shoulder pain: Cross-sectional study.

OBJECTIVE

To correlate the functional performance assessed by means of the Unilateral Seated Shot-Put Test (SSPT) with shoulder muscle strength, range of motion (ROM), and handgrip strength in recreational athletes with chronic shoulder pain.

METHODS AND MATERIALS: The sample was composed of recreational athletes with nonspecific pain in the dominant shoulder ≥3 months, both sexes, aged between 18 and 45 years. We diagnosed shoulder pain by reporting pain intensity ≥3 points on the Numerical Rating Pain Scale and used the Shoulder Pain and Disability Index, Pain-Related Catastrophizing Thoughts Scale, and Baecke Questionnaire. Moreover, shoulder muscle strength, handgrip strength, ROM, and functional performance using the SSPT were evaluated. We used the Spearman correlation coefficient to investigate the correlation between the variables.

RESULTS

Nineteen participants were included. Most of the sample consisted of adult women with adequate body mass and pain predominantly in the right shoulder. We observed higher correlation magnitudes of the SSPT with handgrip strength (rho = 0.818 to 0.833, p < 0.05). Correlations of the SPPT with shoulder musculature strength were of low to moderate magnitude (rho = 0.461 to 0.672, p < 0.05). The only significant correlation (p < 0.05) found was between the SSPT and ROM (horizontal adduction), however, with a weak magnitude (rho <0.50).

CONCLUSION

SSPT correlates strongly with handgrip strength and moderately with shoulder muscle strength in recreational athletes with chronic shoulder pain.
