Are people who do yoga any better at a motor imagery task than those who do not?

BACKGROUND: Yoga is a popular recreational activity in Western society and there is an abundance of literature suggesting that yoga may be beneficial for people with a chronic pain disorder. Despite consistently positive results in the literature, the mechanisms of effect are unclear. On the grounds that chronic pain is associated with disruptions of brain-grounded maps of the body, a possible mechanism of yoga is to refine these brain-grounded maps. A left/right body part judgement task is an established way of interrogating these brain-grounded maps of the body. OBJECTIVE: To determine if people who do regular yoga practice perform better at a left/right judgement task than people who do not. METHODS: Previously collected, cross-sectional data were used. Using a case-control design, participants who reported taking part in regular yoga were selected against age, gender, neck pain and arm pain-matched controls. Participants viewed 40 photographs of a model with their head turned to the left or right, and were asked to judge the direction of neck rotation. They then completed a left/right-hand judgement task. RESULTS: Of the 1737 participants, 86 of them reported regularly taking part in yoga. From the remaining participants, 86 matched controls were randomly selected from all matched controls. There was no difference between Groups (yoga and no yoga) for either response time (p=0.109) or accuracy (p=0.964). There was a difference between Tasks; people were faster (p<0.001) and more accurate (p=0.001) at making left/right neck rotation judgements than they were at making left/right-hand judgements, regardless of group. CONCLUSIONS: People who do regular yoga perform no differently in a left/right judgement task than people who do not.

Best practice care for persistent pain in adults with spinal cord injuries: a systematic review and narrative synthesis of clinical practice guideline recommendations.

PURPOSE: To review clinical practice guidelines (CPGs) and recent literature to identify common recommendations guiding "best practice" pain care for adults with spinal cord injury (SCI). METHODS: We searched four scientific databases and four guideline repositories from January 2010 to February 2022 for CPGs relating to the management of pain following SCI. We excluded guidelines that related to a single treatment modality, complementary medicines, specific disease processes, and guidelines that were not freely available. RESULTS: We identified 1373 records from which 11 met all eligibility criteria. Seven were classified as "tier 1" and were used to generate 46 care components related to neuropathic pain management. We organised these into three themes: screening and assessment, principles of evaluation and management, and management recommendations; and seven subthemes: screening, assessment and diagnosis, addressing complex care needs, ongoing evaluation, management - interventional, management - pharmacological, and management - non-pharmacological. Four CPGs were classified as "tier 2" and were used to provide supporting evidence. We identified 12 recommendations related to the management of nociceptive pain. CONCLUSIONS: This synthesis of recommendations can guide consumers, clinicians, researchers, and policy makers to inform understanding and clinical implementation of evidence-based "best practice" management of pain in adults with SCI.Implications for rehabilitationPersistent pain is a frequent problem for individuals following spinal cord injury and its effective management is challenging for clinicians.High-quality clinical practice guidelines that are up-to-date and readily accessible have the potential to enhance care quality and outcomes.This synthesis of 58 key care recommendations can guide consumers, clinicians, researchers, and policy makers towards improving pain care for adults with spinal cord injuries.
