Background Frozen shoulder (FS) is characterized by a painful, gradual loss of both active and passive glenohumeral motion resulting from progressive fibrosis and contracture of the glenohumeral joint capsule. Deformation of capsuloligamentous tissue is believed to stimulate mechanoreceptors in the tissue and provide the central nervous system with proprioceptive information. It was shown by studies that joint position sense acquity is good near the end of motion in healthy shoulders. There is not enough study about JPS in FS.

Objectives The aim of this study is to compare the effect of mid or end range of motion on joint position sense (JPS) in patients with FS.

Methods Twenty five patients with FS (21 female, 4 male; mean age 53±6 years; age range 44–67) were included in this study. Mean Body Mass Index (BMI) was 29.02±4.89. 11 dominant and 14 nondominant shoulders were measured. JPS was assessed with active repositioning process by inclinometer in flexion, elevation and rotations at mid range (MR) and end range (ER).

Results Error scores at ER were lower than at MR in flexion (p=0.44), elevation (p=0.01) and internal (p=0.00) and external (p=0.19) rotations. There were significant difference in elevation and internal rotation (p<0.05) (Table 1).

Joint position sense at mid range and end range

Conclusions Our study showed that JPS at ER is better than MR. Especially elevation and internal rotation that more affected motions in FS were more sensitive to JPS. It was thought that at end ranges capsuloligamentous structure is stimulated more than mid ranges.
