Study Description

Brief Summary:

Background: Passive oscillatory mobilizations are often employed by physiotherapists to reduce shoulder pain and increase function. However, there is little data about the neurophysiological effects of these mobilizations.

Objectives: To investigate the initial effects of an anteroposterior (AP) shoulder joint mobilization on measures of pain and function in overhead athletes with chronic shoulder pain.

Condition or disease	Intervention/treatment	Phase
Shoulder Pain	Procedure: Mobilization to the glenohumeral joint; Procedure: The manual contact condition; Other: No-contact condition	Not Applicable

Detailed Description:

Design: Double-blind, controlled, within-subjects repeated-measures design Method: Thirty-one overhead athletes with chronic shoulder pain participated. The effects of a 9-min, AP mobilization of the glenohumeral joint were compared with manual contact and no-contact interventions. Pressure pain threshold (PPT), range of movement (ROM), muscle strength, self-reported pain, and disability were measured immediately before and after each intervention.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Mobilization to the glenohumeral joint; This condition consisted on the application of a passive rhythmic AP mobilization to the glenohumeral joint of the affected shoulder	Procedure: Mobilization to the glenohumeral joint; The treatment condition consisted on the application of a passive rhythmic AP mobilization to the glenohumeral joint of the affected shoulder. In particular, a Grade III AP glide to the humeral head with the arm positioned in 90º of glenohumeral abduction and full internal rotation was used. The posterior gliding force to the humeral head was applied maintaining the glide at right angles to the plane of movement and at a frequency of 2 Hz which was controlled by means of a metronome. The arm was returned to its original position between each set.; Other Name: Joint Manipulation
Sham Comparator: The manual contact condition; In this condition the therapist positioned the patient in a mid-range position of glenohumeral abduction and internal rotation and applied the hands to the same contact point as in the treatment condition.	Procedure: The manual contact condition; During the manual contact condition the therapist positioned the patient in a mid-range position of glenohumeral abduction and internal rotation and applied the hands to the same contact point as in the treatment condition. However, a simulated posterior glide was performed but with minimal pressure actually applied. The number of repetitions and sets were as per the treatment condition.; Other: No-contact condition; During the no-contact condition, the subject remained in the initial starting position thorough the entire session but there was no manual contact between the therapist and the participant. The total treatment time was the same as per the other conditions.
No Intervention: No-contact condition; There was no manual contact between the therapist and the participant

Outcome Measures

Primary Outcome Measures :

1. Self-reported shoulder pain [ Time Frame: Change from Baseline at 5 minutes after intervention ]
   Participants were asked to indicate the intensity of their current shoulder pain using a numeric rating pain scale (NRPS). In this scale, 0 is not pain and 10 is the worse pain possible

Secondary Outcome Measures :

1. Shoulder disability [ Time Frame: Change from Baseline at 24 hours after treatment ]
   The DASH is comprised of 30 items (disability/symptom section) and two optional sections related to the impact of pathology on work and sports. Each item is scored from 1 to 5 with increasing values representing more severity of symptoms. The total score for the disability/symptoms section ranges from 30 to 150, but it is then transformed to a scale from 0 (better score possible) to 100 (worse score possible).
2. Shoulder range of movement (ROM) [ Time Frame: Change from Baseline at and 5 minutes after treatment ]
   Active elevation in the scapular plane and passive glenohumeral internal and external rotation were measured using a Standard BASELINE ® 12-inch plastic goniometer following previous guidelines. The 0 degrees of movement is worse and 180 degrees is the better
3. Shoulder muscles strength [ Time Frame: Change from Baseline at 5 minutes after treatment ]
   Isometric strength of the shoulder internal and external rotator musculature was measured using a portable hand-held dynamometer (Nicholas Manual Muscle Tester, Lafayette Instruments, USA). Normal external rotation strength is 20 Newtons and 27 newton in internal rotation strength
4. Pressure pain threshold (PPT) [ Time Frame: Change from Baseline at 5 minutes after treatment ]
   The PPT was measured using an analogue Fisher algometer (Force Dial model FDK, Wagner Instruments) with a surface area at the round tip of 1cm2. The algometer probe tip was applied perpendicular to the skin at a rate of 1kg/cm2/s until the first onset of pain. The PPT value is specific in each subject.The minimal clinically important difference is 2Kg/cm
