Inferior mobilizations are used to treat patients with shoulder dysfunctions. Common
positions recommended for promoting an inferior glide include: (1) an open-packed
position (OPP) in which the shoulder is in 55 degrees of abduction, 30 degrees of
horizontal adduction, and no rotation; (2) neutral position (NP) of the shoulder;
and (3) position of 90 degrees of shoulder abduction (ABDP). Studies comparing
the impact of position on inferior mobilization are lacking. PURPOSE: To determine the effect of shoulder position on humeral movement and
mobilization force during inferior mobilizations. METHODS: Twenty-three subjects
were tested bilaterally. Subjects were placed in the OPP, and an ultrasound
transducer placed over the superior glenohumeral joint. As inferior mobilization
forces were applied through a dynamometer, ultrasound images were taken at rest
and during 3 grades of inferior mobilization. This process was repeated in the NP
and the ABDP. RESULTS: In the NP, movements during grade 1, 2, and 3
mobilizations were 1.8, 3.8, and 4.5 mm, respectively. Movements measured in the
OPP (1.0, 2.4, and 3.6 mm, respectively) and in the ABDP (1.0, 2.2, and 2.3 mm,
respectively) were less. Forces were higher in the NP during grade 1, 2, and 3
mobilizations (51.8, 138.7, and 202.1 N, respectively) than in the OPP (37.2,
91.2, and 139.9 N, respectively) and the ABPD (42.5, 115.3, and 165.5 N,
respectively). DISCUSSION: Mobilization position altered the movement and force
during inferior mobilizations. CONCLUSIONS: Shoulder position should be
considered when utilizing inferior mobilizations.
