Ischemic compression associated with joint mobilization does not promote additional clinical effects in individuals with rotator cuff related shoulder pain: A randomized clinical trial

Abstract

ObjectiveThe objective of this study was to verify which are the additional effects of the ischemic compression (IC) technique associated with joint mobilization techniques on pain, morphological aspects of myofascial trigger points (MTrPs), function, and psychological aspects in individuals with rotator cuff-related shoulder pain (RCRSP). MethodsSixty individuals with RCRSP were randomly allocated intervention sessions the Mobilization Group (MG, n = 20), only joint mobilizations of the shoulder complex; intervention sessions Compression Group (CG, n = 20), with the same mobilizations associated with the IC over MTrPs; and Placebo Group (PG, n = 20), with the same mobilizations associated with placebo of IC. All interventions performed 2 per week, for 6-weeks. Pain was assessed by Visual Analogue Scale and function by the Disabilities of the Arm, Shoulder and Hand questionnaire. The kinesiophobia, pain catastrophizing, perception of improvement, mobility, pain threshold and area the MTrPs were also evaluated at baseline (week-0), after 6-weeks and after 10-weeks. ResultsThere were no between-group difference in pain: CG-MG 0.8 (95% CI 0.4 to 1.2), CG-PG 0.5 (95% CI 0.0 to 0.9), MG-PG -0.3 (95% CI -0.8 to 0.1) after 6-weeks and CG-MG 0.1 (95% CI -0.2 to 0.5), CG-PG -0.7 (95% CI -0.9 to −0,4), MG-PG -0,8 (95% CI -1.07 to 0.5) at 10-weeks. Similar effects were observed on function, characteristics of MTrPs and psychological aspects. ConclusionThe IC technique on the MTrPs of the upper trapezius muscle associated with joint mobilization techniques has no additional effect on pain in individuals with RCRSP.
