Feasibility of a set of wrist-worn novice devices for dual motion comparison of the upper limbs during lateral raise motions

Abstract

Comparison of the upper limbs during natural kinematic motions is nec-essary for early detection of musculoskeletal imbalance between ipsi-lateral and contralateral sides in natural settings. Therefore, this study aims to evaluate the feasibility of a novice set of wrist-worn devices de-signed to assess and compare the dual kinematic motions of the upper limbs during lateral raises. The test-retest and the golden standard and novice device result comparisons were conducted for feasibility as-sessment of the novice set of devices. Pearson correlation coefficients between 0.65 and 0.88 (P < 0.01) and effect sizes between 0.02 and 0.42 indicated feasible application of the novice devices. Considering cor-relation coefficient of 0.65 between the left and right upper limbs, the results show applicable feasibility of the novice device during lateral raises. In conclusion, the novice set of devices for comparing dual up-per limb motions may be applied to assessing and comparing dual up-per limb motions for limb motion comparisons and early detection of dysfunctional movements between the limbs.
