Posterior Shoulder Tightness
Conditions
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.
Interventions
OTHERCross-body stretch (CBS)
CBS is a self administered stretch that aims to stretch posterior shoulder structures
OTHERMobilisation with movement (MWM)
WMW is a musculoskeletal procedure that aims to improve restricted and/or painful range of movement
