The CanPain SCI clinical practice guidelines for rehabilitation management of neuropathic pain after spinal cord injury: 2021 update.

STUDY DESIGN: Clinical practice guidelines. OBJECTIVES: The objective was to update the 2016 version of the Canadian clinical practice guidelines for the management of neuropathic pain in people with spinal cord injury (SCI). SETTING: The guidelines are relevant for inpatient, outpatient and community SCI rehabilitation settings in Canada. METHODS: The guidelines were updated in accordance with the Appraisal of Guidelines for Research and Evaluation II tool. A Steering Committee and Working Group reviewed the relevant evidence on neuropathic pain management (encompassing screening and diagnosis, treatment and models of care) after SCI. The quality of evidence was scored using Grading of Recommendations Assessment, Development and Evaluation (GRADE). A consensus process was followed to achieve agreement on recommendations and clinical considerations. RESULTS: The working group identified and reviewed 46 additional relevant articles published since the last version of the guidelines. The panel agreed on 3 new screening and diagnosis recommendations and 8 new treatment recommendations. Two key changes to these treatment recommendations included the introduction of general treatment principles and a new treatment recommendation classification system. No new recommendations to model of care were made. CONCLUSIONS: The CanPainSCI recommendations for the management of neuropathic pain after SCI should be used to inform practice.

A mapping review of randomized controlled trials in the spinal cord injury research literature.

STUDY DESIGN: Mapping Review. OBJECTIVE: The objective of this study was to map out and characterize the quantity and quality of all published spinal cord injury (SCI) randomized controlled trials (RCTs) with respect to number, sample size, and methodological quality between January 1970 and December 2016. SETTING: Not applicable. METHODS: A literature search of multiple research databases was conducted. Studies adhering to the following criteria were included: the research design was an RCT; written in English; participants were >18 years; and the sample was >50% SCI. Data were extracted pertaining to author(s), year of publication, country of origin, initial and final sample size, intervention, and control. Methodological quality was assessed using the Physiotherapy Evidence Database (PEDro) tool. Data was assessed overall and by each year of publication. RESULTS: In total, 466 RCTs were published 1971-2016 on 29 primary topic areas, with Bladder (n = 78, 16.7%) most common, followed by Pain (n = 54, 11.6%), and Lower Limb (n = 45, 9.7%). Studies were published in 172 unique journals, with the most common being Spinal Cord (n = 68, 14.6%). The most common producer of studies was the United States (n = 191, 41.0%). RCT publications increased linearly until 2012 when the rate tripled, resulting in 40.8% published 2012-2016. A total of 247 (59.4%) RCTs had <30 subjects; there was no change in sample size over time (p = 0.770). The overall mean PEDro score was 5.56 (1.68); scores improved from 5.0 (1.4) in 1976 to 6.3 (1.9) in 2016 (F = 2.230, p < 0.001). CONCLUSIONS: The number of SCI RCTs and their associated sample size remains low; however, methodological quality has improved over time.

The gaming of concussions: a unique intervention in postconcussion syndrome.

OBJECTIVE: To present the case of 2 adolescent high school student-athletes who developed postconcussion syndrome with protracted and limiting visual complaints that markedly affected academic, social, and athletic activity for a year after the onset of symptoms. Both had significant improvement soon after a unique intervention was administered. BACKGROUND: A 14-year-old female soccer and softball player sustained 2 concussions in the same week. She had persistent symptoms for a year that affected her grades and precluded athletic participation. A 15-year-old male football player sustained a concussion during an altercation with 2 other male adolescents. He continued to have symptoms 1 year later, with a marked decrease in academic performance and restriction from athletics. Both adolescents reported blurry vision, photophobia, and associated headache as significant components of the postconcussion syndrome. DIFFERENTIAL DIAGNOSIS: Concussion, postconcussion syndrome, skull fracture, subdural hematoma, epidural hematoma, second-impact syndrome, and visually sensitive migraine. TREATMENT: Both patients were advised to obtain computer gaming glasses to use throughout the day. The female patient was diligent in her use of the glasses, with marked lessening of symptoms. The male patient was less accepting of the glasses but did report lessening of symptoms when using the glasses. UNIQUENESS: We hypothesized that postconcussion syndrome with marked visual complaints would respond to and improve with decreased stimulation of the visual system. This was attempted with the addition of computer gaming glasses. Both adolescent athletes responded well to the filtering of visual stimuli by off-the-shelf computer gaming glasses. CONCLUSIONS: Postconcussion syndrome is a persistent condition with a myriad of symptoms. Two young athletes developed postconcussion syndrome with prominent visual symptoms that lasted a year. The addition of computer gaming glasses markedly lessened symptoms in both patients.
