Abstract
[Purpose] The purpose of this study was to investigate the usefulness of a modified mental rotation intervention for patients with frozen shoulder. [Subjects and Method] The subjects were 40 patients (average age, 54.8 ± 10.5 years) who were randomly distributed to a mental rotation intervention (MRI; 20 persons) group and a control group (20 persons). Both groups performed standard rehabilitation therapy for 1 month, and the MRI group additionally performed modified mental rotation training. [Results] After the one-month intervention, shoulder joint function, shoulder flexion angle, abduction angle and first external rotation angle showed significant (p<0.05) improvements in both groups, and the MRI group showed a further significant (p<0.05) improvement over the control group. [Conclusion] The results of the present study suggest that modified mental rotation training is useful for improving the shoulder function of patients with frozen shoulder.
