This study evaluated joint position sense (JPS) during medial and lateral
rotations of the shoulder in female workers with and without shoulder impingement
syndrome (SIS). Three groups were assessed. The case group consisted of 15 female
assembly line workers (35.5,
SD 5.8 years) with unilateral SIS. Control group 1
consisted of 15 female assembly line workers asymptomatic for SIS (34.4, SD 5.5
years) and control group 2 consisted of 15 female subjects (33.1, SD 6.2 years)
asymptomatic for SIS and with no exposure to activities with the upper limbs. The
JPS was evaluated bilaterally during passive (2 degrees /sec) and active (5
degrees /sec) repositioning tests using an isokinetic dynamometer. The target
angles were 45 degrees of lateral rotation (achieved by medially rotating the
shoulder from 90 degrees of lateral rotation) and 75 degrees of lateral rotation
(achieved by laterally rotating the shoulder from neutral rotation). There were
no differences between sides for all groups (p > 0.05).
There were no differences
in any of the variables between the case group and the control groups (p > 0.05).
The results of this study suggest that JPS during medial and lateral rotations of
the shoulder is not altered in female assembly line workers with SIS.
