Comparative Effects of Two Procedures for the Management of Posterior Shoulder Tightness

Not Applicable

• Conditions: Posterior Shoulder Tightness
• Interventions: Other: Mobilisation with movement (MWM); Other: Cross-body stretch (CBS)

• Registration Number: NCT05128448
• Lead Sponsor: Federal University of Health Science of Porto Alegre

Brief Summary

This study aims to compare the effects of a self-stretch procedures versus a clinician applied musculoskeletal procedure in individuals with posterior shoulder tightness.

Detailed Description

Posterior shoulder mobility has been considered a contributing factor to shoulder related movement dysfunction. There is evidence indicating that posterior shoulder tightness (PST) might be present in individuals with impingement related symptoms, post-operative conditions and overhead athletes. Several studies have investigated the effects of musculoskeletal procedures (joint mobilisations and stretch) in subjects with posterior shoulder tightness (PST). This cross-over design aims to compare the differences between a well-established procedure - the crossbody stretch - versus mobilisation with movement, on range of motion and pain pressure threshold of asymptomatic individuals with unilateral PST.

Arm && Interventions

Group	Intervention	Description
Mobilisation with movement (MWM)	Mobilisation with movement (MWM)	With the participant standing, the restricted shoulder will rest on the clinician's shoulder in the following starting position: 90 degrees of glenohumeral abduction and 90 degrees of elbow flexion and hand holding a treatment belt. The belt will loop around the clinician and patient and will be held by the participant's contralateral hand. The clinician will apply and sustain a pain free caudal or posterolateralcaudal humeral head mobilisation force (whichever is more comfortable to the subject), followed by an active internal rotation (IR) performed by the patient. The IR movement will be performed to a pain free end of range. If possible, an overpressure with be requested, this is achieved by pulling the belt with the contralateral hand. The overpressure should not produce pain, if it does, it will not be performed. 3 sets of 8 repetitions will be applied, sustaining the end of available range for 2 seconds. An interval of 45 seconds will be respected amongst the repetitions.
Cross-body stretch	Cross-body stretch (CBS)	With the participant standing, the restricted shoulder will be self-stretched by conducting a horizontal adduction in 90 degrees of shoulder flexion to a level tolerated by the participant. This position will be held for thirty seconds and repeated four times. An interval of forty five seconds will be respected amongst the repetitions.

Primary Outcome Measures

Name	Time	Method
Horizontal adduction	change immediately after the intervention	Horizontal adduction in 90 degrees of shoulder flexion
Internal rotation	change immediately after the intervention	Internal rotation at 90 degrees of shoulder abduction

Secondary Outcome Measures

Name	Time	Method
Mechanical sensitivity	change immediately after the intervention	Pain pressure threshold with an algometer (Wagner instruments, FPX 25)
