RESUMEN
The global spread of severe acute respiratory syndrome coronavirus 2019 (COVID-19) has affected over 100 countries and has led to the tragic loss of life, overwhelmed health care systems and severely impacted the global economy. Specifically, individuals living with spinal cord injury (SCI) are particularly vulnerable during the COVID-19 pandemic as they often face adverse impacts on their health, emotional well-being, community participation, and life expectancy. The objective of this study was to investigate the lived experience of individuals with SCI during the COVID-19 pandemic in Ontario, Canada. An exploratory design with a qualitative descriptive approach was used to address the study objective. Nine semi-structured interviews were conducted with individuals with traumatic and non-traumatic SCI (37-69 years, C3-L5, AIS A-D, and 5-42 years post-injury). Using reflexive thematic analysis, the following themes were created: (1) Caregiver exposure to COVID-19; (2) Staying physically active in quarantine; (3) Living in social isolation; (4) Difficulty obtaining necessary medical supplies; (5) Access to health services and virtual care during COVID-19; and (6) Fighting COVID-19 misinformation. This is one of the first studies to explore the impact of COVID-19 on individuals living with SCI in Ontario. This study contributes to a greater understanding of the challenges faced by individuals living with SCI and provides insight into how to better support and respond to the specific and unique needs of individuals with SCI and their families during a national emergency or pandemic.

This study examined changes in body mass and body mass index (BMI), physical activity, and dietary intake in Canadian university students during the first year of the COVID-19 pandemic. Two self-reported recall surveys were conducted: after the first lockdown in September 2020 (T1) and following the second lockdown in March 2021 (T2). Eligible participants were full-time undergraduate students attending a Canadian university and residing in Canada during the first year of the pandemic. At T1, 510 students (99 male, 411 female) completed the survey, and of those, 135 (32 males, 103 females) completed the survey at T2 (73% attrition). At both T1 and T2, most participants were 18-24 years of age (93% and 90%, respectively), Caucasian (73% and 78%, respectively), and resided in the province of Ontario (79% and 80%, respectively). Body mass increased from T1 to T2 (+0.91 ± 3.89 kg t(132) = -2.7, p = 0.008). BMI also increased from T1 to T2 (+0.30 ± 1.33 kg/m2 [t(130) = -2.5, p = 0.012), with a greater number of participants within the overweight range (19.8% versus 24.4%, respectively). At T1, 38% of the participants reported a decrease in physical activity, while the number of students reporting a decrease in activity increased to 56% at T2. Dietary energy intake decreased from 1678 ± 958 kcal/day at T1 to 1565 ± 842 kcal/day at T2 [c2(1) = 7.2, p = 0.007]. Diet quality also decreased, with participants not meeting the recommended daily allowance for essential macro and micronutrients. A decrease was observed in daily servings of fruits (-27%, p < 0.001), vegetables (-72%, p < 0.001), and grains (-68%, p < 0.001). In conclusion, despite a small decrease in dietary energy intake, a modest weight gain occurred during the first year of the COVID-19 pandemic in this cohort of Canadian university students, which was potentially related to decreased physical activity and diet quality.
RESUMEN
The purpose was to investigate the effects of progressive resistance training (PRT) and creatine supplementation in stroke survivors. Participants were randomized to one of two groups: creatine (n = 5; 51 ± 16y) or placebo (n = 3; 73 ± 8y) during 10 weeks of supervised PRT. Prior to and following PRT and supplementation, assessments were made for body composition (lean tissue and fat mass), muscle thickness, muscle strength (1-repetition maximum), functional exercise capacity (6-minute walk test, Berg Balance Scale; BBS), cognition (Montreal Cognitive Assessment; MoCA), and symptoms of anxiety (Generalized Anxiety Disorder Assessment-7; GAD-7) and depression (Center for Epidemiological Studies Depression Scale; CES-D). There were time main effects for leg press strength (increased; p = 0.001), chest press strength (increased; p = 0.003), elbow flexor muscle thickness (increased; p = 0.007), BBS (increased; p = 0.002), MoCA (increased; p = 0.031) and CES-D (decreased; p = 0.045). There was a group x time interaction for the 6 minute walk test (p = 0.039). The creatine group significantly increased walking distance over time (p = 0.002) with no change in the placebo group (p = 0.120). Ten weeks of PRT had some positive effects on measures of muscle strength and size, balance, cognition and depression. The addition of creatine to PRT significantly improved walking performance in stroke survivors.
RESUMEN
STUDY DESIGN: Multicenter, randomized, double-blind, placebo controlled, clinical trial. OBJECTIVE: The objective of this paper is to evaluate the effectiveness of cannabinoids and an anti-inflammatory diet, alone and in combination, for the management of neuropathic pain (NP) after spinal cord injury (SCI). SETTING: Two Canadian SCI rehabilitation centers. METHODS: A sample of 144 individuals with SCI will receive either an anti-inflammatory diet, cannabinoids or a placebo for 6 weeks. Following this, a combined effect of these treatments will be evaluated for a further 6 weeks. The primary outcome measure will be the change in NP as assessed by the numeric rating scale (NRS). Secondary outcomes will include changes in inflammation, mood, sleep, spasticity, cost-effectiveness, and function. CONCLUSION: This study will assess the efficacy of an anti-inflammatory diet and cannabinoids (individually and in combination) for the treatment of NP following SCI. Results may reveal a cost-effective, side-effect free intervention strategy which could be utilized for the long-term management of NP following SCI.

STUDY DESIGN: Descriptive phenomenological approach. OBJECTIVES: This study explored the lived experience of sexuality for men after spinal cord injury (SCI) and described the current state of tools and resources available to assist with sexual adjustment from the perspective of men living with SCI. SETTING: Men living in the community in Ontario, Canada. METHODS: Six men (age 24-49 years) with complete or incomplete SCI (C4-T12; <1-29 years post injury) participated in one individual, in-depth, standardized, open-ended interview (68-101 min). Analysis was conducted using Giorgi's method, and involved within case analysis followed by cross-case analysis. RESULTS: All participants reported that resources available to support sexual adjustment after SCI were inadequate, and the majority of men felt their healthcare providers lacked knowledge regarding, and comfort discussing sexuality after SCI. Men reported sexuality was not a priority of the rehabilitation centers and felt that healthcare providers did not understand the importance of addressing sexuality. Existing resources were described as too clinical and not necessarily relevant given changes in sensation and mobility post injury. Participants provided recommendations for the effective delivery of relevant sexual education information. CONCLUSIONS: To improve quality of life for men after SCI, suitable resources must be available to support sexual rehabilitation post injury. Future research should focus on developing strategies to facilitate discussions about sexuality between individuals with SCI and healthcare providers, and on developing resources that are effective and relevant for these men.

BACKGROUND: Although exercise training has benefits for individuals with multiple sclerosis (MS), research regarding the type of exercise equipment that requires the greatest aerobic demand, and consumer-based preferences, is lacking. OBJECTIVE: To determine the aerobic demands of various pieces of accessible exercise equipment and consumer-based preferences on several domains. METHODS: Ten individuals with moderate-severity MS had their VO2 measured during 10 minutes of moderate-intensity arm ergometry (AE), body-weight support treadmill training (BWSTT), recumbent arm-leg exercise (NuStep), FES-arm exercise (RT300), FES-leg exercise (RT300) and FES arm-leg exercise (RT200). VO2peak test was also measured on the NuStep and the RT200. Equipment preferences were determined by questionnaire after moderate exercise sessions. RESULTS: AE required a lower VO2 compared to the NuStep (pâ=â0.02), and FES-arm exercise required a lower VO2 compared to the NuStep (pâ=â0.01) and FES arm-leg exercise (pâ=â0.04). There was no difference in VO2peak when using the NuStep or FES arm-leg exercise. AE was perceived as safer than BWSTT, but otherwise there were no preferences for any equipment. CONCLUSIONS: For individuals with moderate-severity MS, arm-only exercise requires less aerobic demands than combined arm-leg exercise at a moderate intensity. Perceived risks may be greater when exercise requires a transfer, upright positioning, or assistance.

BACKGROUND: Spinal cord injury (SCI) and multiple sclerosis (MS) are associated with increased risks of depression. Acute exercise may improve mood in these populations via its affect on inflammation. OBJECTIVE: To determine if acute exercise can positively affect mood in individuals with SCI and MS, and whether exercise-induced changes in inflammation contribute to such improvements. METHODS: Thirteen participants completed 30 minutes of moderate-intensity exercise. Mood data (POMS questionnaire) and blood samples were taken before and after exercise, and blood was analyzed for inflammatory mediators and kynurenine pathway metabolites. RESULTS: There was a significant reduction in total mood disturbance (TMD) pre to post-exercise, and pre to one-hour post-exercise. There was a significant decrease in TNF-α from pre to post-exercise, with further reductions one-hour post-exercise. There were no correlations between changes in TMD and changes in inflammation. However, changes in certain cytokines showed significant or trending correlations with changes in subsets of the POMS. Likewise, there was a trend for a correlation between exercise-induced changes in KYN/TRP and depression (pâ=â0.096). CONCLUSIONS: Acute exercise can positively affect mood after SCI and MS, and this change may be partially accounted for by exercise-induced changes in inflammation. This relationship may be, in part, kynurenine pathway-dependent.

Objective: The objective of the current study was to describe the observed changes in nutrient intakes following a 3-month anti-inflammatory diet, and to explore potential relationships between the change in nutrients and the change in various inflammatory mediators.Design: A secondary analysis of a prior randomized controlled clinical trial.Setting: Individuals with SCI within the Niagara region.Participants: Twenty individuals with various levels and severities of SCI.Intervention: Three-month anti-inflammatory diet.Outcome Measures: The change in nutrient intake and corresponding changes to various inflammatory mediators.Results: The treatment group demonstrated a significant reduction in fat intake (P = 0.02), a significant increase in protein intake (P = 0.02), and no change in carbohydrates (P = 0.23) or energy intake (P = 0.10). The treatment group showed a significant increase in some nutrients with established anti-inflammatory properties including vitamins A, C, and E, and omega-3 fatty acids (P < 0.01). Significant reductions in proinflammatory nutrients were observed including trans fatty acids (P = 0.05), caffeine (P < 0.01), and sodium (P = 0.02). The treatment group also showed significant reductions in the proinflammatory mediators interferon-y (P = 0.01), interleukin-1ß (P < 0.01), and interleukin-6 (P < 0.05). Further, several proinflammatory mediators were negatively correlated with anti-inflammatory nutrients, including vitamin A, carotenoids, omega-3 fatty acids, and zinc.Conclusion: This study provides evidence that dietary alterations are effective at reducing chronic inflammation in individuals with SCI and provides a preliminary assessment of the related nutrient changes.

STUDY DESIGN: One-year follow-up of a randomized clinical trial. OBJECTIVES: Examine voluntary dietary compliance 1 year following the cessation of the intervention and the persistence of accrued benefits related to neuropathic pain and mood. SETTING: Outpatient rehabilitation program within the Niagara region. METHODS: Five individuals (4 female, 1 male; age 50.6 ± 11.8 years) with chronic SCI (C5-L3; ISNCSCI: A-D; 7-40 years post injury) who had previously completed a 3-month anti-inflammatory diet were reassessed after 1 year for measures related to dietary compliance, CES-D scores of depression, and NPQ scores of neuropathic pain. RESULTS: There was a significant reduction in diet compliance at the 1-year follow-up in comparison to the end of the dietary intervention at 3 months (92.6% versus 43.0%, p < 0.01). CES-D scores showed a trend toward an increase from 3 months to follow-up (8.0 versus 21.4, p = .10) whereby follow-up CES-D scores were no longer statistically different from baseline (p = 0.74). Sensory NPQ scores showed no significant change from 3 months to follow-up (25.2 versus 29.1, p = 0.42) and remained significantly lower than baseline (p = 0.02). Affective NPQ scores were significantly increased from 3 months to follow-up (27.7 versus 40.1, p = 0.05). Sensitivity NPQ scores showed no significant change from 3 month to follow-up (28.2 versus 33.5, p = 0.34), but returned to a score that was statistically similar to baseline (p = 0.15). CONCLUSIONS: These results emphasize the importance of continued compliance to a diet with anti-inflammatory properties for the purposes of maintaining benefits related to mood and neuropathic pain in individuals with SCI. SPONSORSHIP: This study was supported by the Ontario Neurotrauma Foundation.

RESUMEN
The purpose of this study was to explore the barriers and facilitators of an anti-inflammatory diet in people with spinal cord injury. Six participants (age range of 23-68 years, three women and three men) who had previously completed an anti-inflammatory diet study were interviewed. Facilitators identified were family support, autonomy over meal choice, peer support, health benefits gained, and implementation of adherence strategies. The main barriers discussed were lack of motivation after study period ended, social events, diet expenses, and lack of knowledge about the diet. Several health benefits including reductions in pain, edema, and improvements in cognition and mobility were reported.
RESUMEN
This "Perspectives" article puts forward the notion that measuring heart rate variability, or other forms of cardiac autonomic regulation, after spinal cord injury must be performed during a test of autonomic stress. Resting values of heart rate variability are often similar to those obtained from able-bodied individuals, which may therefore be falsely interpreted as normal or healthy autonomic regulation. However, evidence shows that despite normal resting values, cardiac autonomic control is impaired when individual with spinal cord injury are subjected to a cold face test, head-up tilt, or recovery from exercise. Accordingly, examination of cardiac autonomic function must be performed during an autonomic challenge, as resting measures do not accurately reflect the state of cardiovascular regulation after spinal cord injury and can provide false information.

Background: Although cardiac autonomic dysfunction is a contributing factor for cardiovascular disease development in individuals with a spinal cord injury (SCI), it remains poorly understood. Heart rate variability (HRV) analysis has the potential to non-invasively assess the cardiac autonomic nervous system. The study objectives are (a) to determine if there are differences in HRV measures across neurological level of impairment (NLI) and American Spinal Cord Injury Association Impairment Scale (AIS) subgroups, and (b) to determine if there is a relationship between HRV frequency measures (low frequency [LF] and high frequency [HF]) at rest. Methods: We conducted a secondary data analysis of a primary data set from a published cross-sectional study of electrocardiogram recordings of 56 subjects (44 men and 12 women, mean age ± SD = 46.75 ± 12.44 years) with a chronic traumatic SCI (C1-T12, AIS A-D, ≥2 years post injury). HRV was analyzed using time and frequency domain measures. Results: There were no significant HRV differences across NLI and AIS subgroups. The LF and HF indices were positively correlated in the entire sample (r = 0.708, p < .0001) and among impairment subgroups. Conclusion: No differences were observed in the HRV time and frequency measures when compared across NLI and AIS subgroups. The results were considered inconclusive, since possible explanations include inadequate sample size as well as other physiological considerations. A positive correlation was found between LF and HF when assessed at rest. The relationship between LF and HF may not necessarily represent a rebalanced autonomic nervous system, but it does question the utility of solely measuring LF:HF at rest in persons with chronic SCI.

OBJECTIVES: To describe the process and outcomes of using a new evidence base to develop scientific guidelines that specify the type and minimum dose of exercise necessary to improve fitness and cardiometabolic health in adults with spinal cord injury (SCI). SETTING: International. METHODS: Using Appraisal of Guidelines, Research and Evaluation (AGREE) II reporting criteria, steps included (a) determining the guidelines' scope; (b) conducting a systematic review of relevant literature; (c) holding three consensus panel meetings (European, Canadian and International) to formulate the guidelines; (d) obtaining stakeholder feedback; and (e) process evaluation by an AGREE II consultant. Stakeholders were actively involved in steps (c) and (d). RESULTS: For cardiorespiratory fitness and muscle strength benefits, adults with a SCI should engage in at least 20 min of moderate to vigorous intensity aerobic exercise 2 times per week AND 3 sets of strength exercises for each major functioning muscle group, at a moderate to vigorous intensity, 2 times per week (strong recommendation). For cardiometabolic health benefits, adults with a SCI are suggested to engage in at least 30 min of moderate to vigorous intensity aerobic exercise 3 times per week (conditional recommendation). CONCLUSIONS: Through a systematic, rigorous, and participatory process involving international scientists and stakeholders, a new exercise guideline was formulated for cardiometabolic health benefits. A previously published SCI guideline was endorsed for achieving fitness benefits. These guidelines represent an important step toward international harmonization of exercise guidelines for adults with SCI, and a foundation for developing exercise policies and programs for people with SCI around the world.

OBJECTIVE: The objective of this prospective RCT was to compare the efficacy of a web-based teaching tool to traditional didactic teaching in IVF patients. METHODS: Forty women undergoing their first IVF cycle were randomly allocated to an interactive web-based teaching session or a nurse-led didactic teaching session. The primary outcome measure was participant knowledge regarding the IVF process, risks, and logistics assessed before and after the respective teaching session. Secondary outcomes included patient stress, assessed before and after the respective teaching session, and patient satisfaction, assessed following the respective teaching session and on the day of embryo transfer (following implementation of the teaching protocol). RESULTS: Both groups demonstrated similar and significant improvements in knowledge and stress after exposure to their respective teaching sessions. The web-based group was significantly more satisfied than the didactic teaching group. Web-based teaching was also shown to be equally effective for participants of high versus low income and education status for knowledge, stress, and satisfaction. CONCLUSION: This study provides preliminary support for the use of web-based teaching as an equally effective tool for increasing knowledge and reducing stress compared to traditional didactic teaching in IVF patients, with the added benefit of increased patient satisfaction.

OBJECTIVE: To synthesize and appraise research testing the effects of exercise interventions on fitness, cardiometabolic health, and bone health among adults with spinal cord injury (SCI). METHODS: Electronic databases were searched (1980-2016). Included studies employed exercise interventions for a period ≥2 weeks, involved adults with acute or chronic SCI, and measured fitness (cardiorespiratory fitness, power output, or muscle strength), cardiometabolic health (body composition or cardiovascular risk factors), or bone health outcomes. Evidence was synthesized and appraised using Grading of Recommendations Assessment, Development, and Evaluation (GRADE). RESULTS: A total of 211 studies met the inclusion criteria (22 acute, 189 chronic). For chronic SCI, GRADE confidence ratings were moderate to high for evidence showing exercise can improve all of the reviewed outcomes except bone health. For acute SCI, GRADE ratings were very low for all outcomes. For chronic SCI, there was low to moderate confidence in the evidence showing that 2-3 sessions/week of upper body aerobic exercise at a moderate to vigorous intensity for 20-40 minutes, plus upper body strength exercise (3 sets of 10 repetitions at 50%-80% 1-repetition maximum for all large muscle groups), can improve cardiorespiratory fitness, power output, and muscle strength. For chronic SCI, there was low to moderate confidence in the evidence showing that 3-5 sessions per week of upper body aerobic exercise at a moderate to vigorous intensity for 20-44 minutes can improve cardiorespiratory fitness, muscle strength, body composition, and cardiovascular risk. CONCLUSIONS: Exercise improves fitness and cardiometabolic health of adults with chronic SCI. The evidence on effective exercise types, frequencies, intensities, and durations should be used to formulate exercise guidelines for adults with SCI.

PURPOSE: This narrative explores the lived experience of a young woman, Rebecca, and her transitioned body image after sustaining and being treated for a spinal cord injury. METHOD: Data were collected from a single semi-structured in-depth interview. RESULTS: Rebecca disclosed her transitioned body image experiences after sustaining a spinal cord injury and being treated by medical staff immediately following her injury. Before her injury, she described a holistic body experience and named this experience her "temple". During intensive care in the hospital, she explained her body was treated as an object. The disconnected treatment of her body led to a loss of the private self, as she described her sacred body being stripped away - her "temple" lost and in ruins. CONCLUSIONS: Body image may be an overlooked component of health following a spinal cord injury. This narrative emphasizes the importance of unveiling body image experiences after the treatment of a spinal cord injury to medical professionals. Lessons of the importance of considering the transitioned body experiences after a spinal cord injury may help prevent body-related depression and other subsequent health impacts. Recommendations for best practice are provided. Implications for Rehabilitation Spinal Cord Injury ⢠A spinal cord injury may drastically change a person's body image, thereby significantly impacting psychological health ⢠More effective screening for body image within the medical/rehabilitation context is needed to help practitioners recognize distress ⢠Practitioners should be prepared to refer clients to distress hotlines they may need once released from treatment.

BACKGROUND: Clinically silent autonomic dysfunction with bowel and bladder care, are postulated to contribute to cardiovascular disease after chronic spinal cord injury (SCI). OBJECTIVE: We describe the frequency and severity of dysreflexic episodes, termed transient blood pressure elevations (T-BPE) over 48 hours in adults with cervical or high-thoracic motor-complete SCI. SETTING: Tertiary SCI Rehabilitation Centre in Toronto, Canada. PARTICIPANTS: Individuals with chronic SCI, C1-T3 AIS A or B, >1 year post-injury, living in the community (n=19). OUTCOME MEASURES: Data were obtained via 48-hour ambulatory blood pressure (BP) and heart rate (HR) monitoring, with data captured at 10-minute intervals and a concurrent diary describing activities of daily living, and bladder/bowel routines. T-BPE were defined as a ≥ 40 mmHg elevation in systolic blood pressure (SBP) above the participant's supine baseline. Severe (≥ 60-79 mmHg) and Extreme ≥80 mmHg elevations in SBP were described. RESULTS: Thirteen participants experienced T-BPE within the assessment period, with 7/13 experiencing "severe", and 3/13 experiencing "extreme" SBP elevations. The median number of T-BPE was 8 (IQR = 3), and the mean ± SD SBP during T-BPE was 150 ± 16 mmHg, These T-BPE were verified as dysreflexic events using a conservative definition of a >40 mmHg increase in SBP, with a concurrent 10 bpm decrease in HR, above the 48-hour average SBP, yielding 12/19 participants with T-BPE. CONCLUSIONS: T-BPE were frequent, often with severe or extreme elevations in SBP, despite few reported symptoms. Recognition and management of these dysreflexic events associated with T-BPE are needed, which may ameliorate cardiovascular disease risk.

Objective: To examine the potential influence of chronic inflammation on peripheral motor nerve function in vivo following spinal cord injury (SCI). Methods: This study was part of a randomized, parallel-group, controlled clinical trial. The study included 20 participants with varying levels and severities of SCI randomized (3:2) to either a treatment group, consisting of a 12-week anti-inflammatory diet program, or control group. Outcome measures were assessed at baseline, 1 month, and 3 months and consisted of measures of motor nerve conduction velocity (NCV) and amplitude as well as markers of inflammation as assessed by various pro- and anti-inflammatory cytokines. Results: Despite a significant reduction in inflammation in the treatment group, 2-way repeated measures analysis of variance (ANOVA) showed no significant Group × Time interaction for motor NCV (p = .77) or M-wave amplitude (p = .61). Further, the change in motor NCV and M-wave amplitude were not shown to be associated with the change in inflammatory mediators as assessed via a backwards elimination multiple regression analysis. Conclusion: These results suggest that at physiologically relevant concentrations, inflammatory mediators may not have a substantial influence on peripheral motor nerve conduction in vivo following SCI. Future studies may still be warranted to examine the potential for central effects.
