Pregabalin has been approved for the treatment of the neuropathic pain following spinal cord injury (SCI). We performed a systemic review and meta-analysis of randomized, controlled, multicenter trials to evaluate the efficacy and safety of pregabalin for SCI-induced neuropathic pain. ⋯ Our results showed pregabalin was efficacious and might be safe treatment for chronic pain followed SCI.

Pain Catastrophizing and Function In Individuals With Chronic Musculoskeletal Pain: A Systematic Review and Meta-Analysis.
Pain catastrophizing (PC) is the most consistent psychosocial factor predicting of adjustment to chronic pain and may contribute to the development and long-term maintenance of chronic pain. The aim of this review was systematically review and critically appraise the concurrent and longitudinal associations between PC and both pain intensity and disability in individuals with chronic musculoskeletal pain (CMP). ⋯ Despite the very low quality of the available evidence, the general consistency of the findings highlights the potential role that PC may play in delaying recovery from CMP. Research that uses higher quality study designs and procedures would allow for more definitive conclusions regarding the impact of PC on pain and function.

This systematic review aimed to identify and evaluate prognostic factors for long-term (≥6 mo) physical functioning in patients with chronic musculoskeletal pain following multidisciplinary rehabilitation (MDR). ⋯ While pain intensity and long-term chronicity did not predict physical functioning in chronic pain patients after MDR, poor pretreatment physical and psychological functioning influenced the prognosis negatively. Thus, treatment should further target and optimize these modifiable factors and an increased focus on positive, psychological protective factors may perhaps provide an opening for yet untapped clinical gains.

Offset analgesia (OA) is a test paradigm increasingly used to estimate endogenous pain modulation characterized by a disproportionally profound analgesia after a small decrease of a heat stimulus. This systematic review and meta-analysis examined the magnitude and difference of OA in healthy participants and chronic pain patients. ⋯ Results indicate that pain-free participants show a larger OA response when rating pain continuously compared with individuals with chronic pain.

The Effects of Motor Imagery on Pain and Range of Motion in Musculoskeletal Disorders: A Systematic Review With Meta-analysis.
In recent years, there has been an increase in the use of motor imagery (MI) in the rehabilitation of musculoskeletal pain conditions. Across the literature, most reviews have yet to consider Laterality Judgement Task training as a form of MI method. This review aimed to evaluate the effectiveness of using MI as an adjunct to standard rehabilitation on the improvement of pain and range of motion parameters when managing patients with musculoskeletal pain conditions. ⋯ The results suggest that MI may be effective for pain relief and improvement in range of motion among chronic musculoskeletal pain conditions, although conclusion is based on a limited certainty of evidence as assessed using the GRADES (Grading of Recommendation, Assessment, Development and Evaluation) approach.
