This study described the development of the scale for measuring felt shoulder stiffness (SMFS). The questionnaire was 28 items selected from previous studies.
The factor analysis was conducted on responses from 506 students, and three factors were extracted and were identified: I) Numbness and a prickle; II) Dull pain of a deep part; III) Sense of congestion. All these factors had high degrees of internal consistency.
The scores of the “Numbness and a prickle” were significantly correlated with the Hostility action scores (r = 0.17). On the other hand, the scores of the “Dull pain of a deep part” were non-significantly correlated with the Hostility action scores, but were significantly correlated with the Depression scores (r = 0.27), and Anxiety scores (r = 0.27). The scores of the “Sense of congestion” were significantly correlated with the Hostility action scores (r = 0.24), the Depression scores (r = 0.23), and Anxiety scores (r = 0.16).
These results suggest that SFMS may be a reliable instrument for assessing shoulder stiffness in Japanese.
