Pain relief due to physiotherapy doesn’t change the motor function of the shoulder

The effects of rotator cuff tear on shoulder proprioception

“…Different methods have been used for the assessment of joint position sense [22,43,[45][46][47][48]: the active/active, activeassisted, and passive/active protocols evaluating one or more between shoulder forward flexion, abduction, and internal and external rotation have been reported. Regarding the equipment used, proprioception has been investigated through isokinetic dynamometer [44,[49][50][51], inclinometer [51,52], laser pointer [52], goniometer [52], continuous passive motion device [53], fabricated laboratory equipment [54][55][56][57], and motion analysis system [58,59].…”

Sensing the body in chronic pain: A review of psychophysical studies implicating altered body representation

“…Of these two senses, position sense is the most widely tested sense in people with chronic pain, often involving the reproduction of a remembered posture or limb position (generally, in the absence of visual feedback). While there is evidence of reduced acuity during joint position sense tasks in those with chronic pain (Gill and Callaghan, 1998;Brumagne et al, 2000;Newcomer et al, 2000b;O'Sullivan et al, 2003;Pötzl et al, 2004;Cuomo et al, 2005;Knox et al, 2006;Paulus and Brumagne, 2008;Lewis et al, 2010;Ha et al, 2011;Sheeran et al, 2012), there are also a number of studies that have found no significant differences in limb repositioning acuity between patient and control groups (Lam et al, 1999;Newcomer et al, 2000a;Descarreaux et al, 2005;Asell et al, 2006;Lee et al, 2010;Mörl et al, 2011).…”

Patients with Subacromial Pain Syndrome Present no Reduction of Shoulder Proprioception: A Matched Case‐Control Study

“…The absence of the impairment of the proprioception of the shoulder in a pain‐free movement in patients with SAPS is a novelty of our study that extends and complements previous work. We have chosen the shoulder rotation movement with intermediate angles to avoid causing pain in the patients, since it is already known that pain influences proprioceptive acuity in shoulder injuries . Thus, we focused the assessment on the proprioceptive information from the mechanoreceptors of the shoulder of patients with SAPS rather than the influence of the pain symptom.…”

“…We have chosen the shoulder rotation movement with intermediate angles to avoid causing pain in the patients, since it is already known that pain influences proprioceptive acuity in shoulder injuries. 8,19,25 Thus, we focused the assessment on the proprioceptive information from the mechanoreceptors of the shoulder of patients with SAPS rather than the influence of the pain symptom. Therefore, our findings suggest that the SAPS do not appear to involve damage in the mechanoreceptors or changes in the neural pathway due to the normal response of proprioception in pain-free movement.…”
