Summary

To identify biomechanical and sensibility changes in people with posterior capsule tightness in people with and without shoulder pain.

Detailed description

Some studies have shown that posterior capsule tightness can be related with shoulder dysfunctions and kinematics alterations. This study will be divided in two studies. The purpose of study 1 will be to assess the scapular and humeral kinematics, the strength of the shoulder external rotators and the pressure pain threshold in subjects with posterior capsule tightness with and without shoulder pain. Study 2 will verify the effects of two different treatments in subjects with posterior capsule tightness and shoulder pain on the same variables of study 1. One-hundred subjects will participate in the first study and will be divided in 4 groups: Group 1 - 25 subjects with shoulder pain and posterior capsule tightness; Group 2 - 25 subjects with no shoulder pain and no posterior capsule tightness; Group 3 - 25 subjects with shoulder pain and no posterior capsule tightness; and group 4 - 25 subjects with no shoulder pain and no posterior capsule tightness. All subjects will complete the DASH and Shoulder Pain and Disability Index questionnaires. External and internal rotation range of motion, strength of the external rotators, scapular kinematics and humeral translations during arm elevation, and pressure pain threshold will be measured. For the second study 50 subjects with shoulder pain and posterior capsule tightness will be recruited. The subjects will be randomly divided in 2 groups: experimental group or control group. The experimental group will receive glenohumeral posterior mobilization, stretching of posterior capsule and strengthening of the shoulder external rotators. The control group will do ultrasound;, stretching for the upper trapezius and scapular squeezing. Both groups will receive intervention for 3x/week/4 weeks. All subjects will be supervised for one physiotherapist and same variables from study 1 will be analyzed at pre and post-intervention.

Conditions

• Shoulder Pain

Interventions

Type	Name	Description
OTHER	Posterior shoulder mobilizations	A second investigator performed 5min of posterior capsule shoulder mobilization for the experimental group, 3times/week during 4 weeks.
OTHER	External rotators strengthening	Individuals performed 3x10 repetitions of external rotators strengthening in sidelying position 3times/week during 4 weeks.
OTHER	Placebo ultrasound	A second investigator performed 5min of placebo ultrassound for the control group, 3times/week during 4 weeks.
OTHER	Scapular squeezing	Individuals performed 3x10 repetitions scapular squeezing exercise 3times/week during 4 weeks.
OTHER	Upper trapezius stretching	Individuals performed 3x30s of upper trapezius stretching, 3times/week during 4 weeks.
OTHER	Posterior Capsule Stretching	Individuals performed 3x30s of posterior capsule stretching, 3times/week during 4 weeks.
