Brief 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.

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: TRIPLE

Study Groups

Control group

This group will perform during 4 weeks:

• placebo ultrasound during 5min ;
• scapular squeezing in the sitting position (3x10repetitions);
• upper trapezius stretching (in sitting position, 3x30s and 30s of rest).

Group Type: PLACEBO_COMPARATOR

Placebo ultrasound

Intervention Type: OTHER

A second investigator performed 5min of placebo ultrassound for the control group, 3times/week during 4 weeks.

Scapular squeezing

Intervention Type: OTHER

Individuals performed 3x10 repetitions scapular squeezing exercise 3times/week during 4 weeks.

Upper trapezius stretching

Intervention Type: OTHER

Individuals performed 3x30s of upper trapezius stretching, 3times/week during 4 weeks.

Experimental group

This group will perform during 4 weeks:

• posterior shoulder mobilizations during 5min (mobilizations during 30s and 30s of rest);
• external rotators strengthening in sidelying positions with load (3x10repetitions);
• posterior capsule stretching (sleeper stretch in sidelying position, 3x30s and 30s of rest).

Group Type: ACTIVE_COMPARATOR

Posterior shoulder mobilizations

Intervention Type: OTHER

A second investigator performed 5min of posterior capsule shoulder mobilization for the experimental group, 3times/week during 4 weeks.

External rotators strengthening

Intervention Type: OTHER

Individuals performed 3x10 repetitions of external rotators strengthening in sidelying position 3times/week during 4 weeks.

Posterior Capsule Stretching

Intervention Type: OTHER

Individuals performed 3x30s of posterior capsule stretching, 3times/week during 4 weeks.

Eligibility Criteria

Inclusion Criteria

• low flexion test (flexion + internal rotation) > 7°, between arms;
• symptoms consistent to shoulder impingement and arm elevation close to 150° as determined by digital inclinometer. The diagnosis for SIS was made based on a clinical examination and self-reported history. To be classified as having shoulder impingement, subjects had to present with at least 3 of the following: positive Neer test, positive Hawkins test, positive Jobe test, pain with passive or isometric resisted shoulder lateral rotation, pain with active shoulder elevation, and pain in the anterolateral shoulder region.

Exclusion Criteria

• were pregnant;
• had ligamentous laxity based on positive Sulcus test, Apprehension test or anterior drawer;
• had history of clavicle, scapula or humerus fracture;
• history of shoulder surgery or traumatic lesion; -had adhesive capsulitis or scoliosis; - had systemic illnesses;
• transpore tape allergy;
• body mass index > 28kg/m2;
