Health promotion and cardiovascular risk reduction in people with spinal cord injury: physical activity, healthy diet and maintenance after discharge- protocol for a prospective national cohort study and a preintervention- postintervention study

Leisure-Time Physical Activity Participation in Middle-Aged and Older Adults With a Spinal Cord Injury in Australia

Objectives

Adults with spinal cord injury (SCI) are often sedentary, increasing their risk of cardiometabolic diseases. Leisure-time Physical Activity (LTPA) is physical activity completed during recreation time for enjoyment. We aimed to quantify LTPA in people ≥45 years with SCI and to explore its relationship with participants' characteristics.

Methods

This is a secondary analysis on a subset of the Australian International SCI Survey in participants ≥45 years, at least 12 months post-injury. We described levels of LTPA and used multivariable regressions to estimate the associations between participant characteristics and LTPA.

Results

Of 1,281 participants (mean age: 62.7 years, mean time since injury: 18.7 years; 74% males) 44% reported no participation in LTPA. The average LTPA participation was 197 (SD 352) minutes per week (median: 50). Females (β = -62.3, 95% CI [-112.9, -11.7]), and participants with non-traumatic injuries (β = -105.2, 95% CI [-165.9, -44.6]) performed less LTPA. Time since injury was not associated with moderate-to-heavy LTPA (LR: Probability > F = 0.785).

Conclusion

LTPA promotion in the SCI population ≥45 years focusing on females and non-traumatic injuries is warranted.

Monitoring outcome measures for cardiometabolic disease during rehabilitation and follow-up in people with spinal cord injury

STUDY DESIGN

Controlled pragmatic intervention with follow-up.

OBJECTIVES

To describe cardiometabolic risk outcomes after a pragmatic intervention implemented into standard spinal cord injury (SCI) rehabilitation.

SETTING

Inpatient SCI rehabilitation in East-Denmark.

PARTICIPANTS

Inpatients, >18 years, having sustained a SCI within the last 12 months at admission to rehabilitation, regardless of etiology, neurological level or completeness of the lesion or mobility status.

METHODS

Patient education on health promotion was guided by evidence and included feedback on peak oxygen uptake (VO2peak) (primary outcome measure), body mass index (BMI), Dual energy X-ray absorptiometry and metabolic profile (secondary outcome measures). Paired t-tests, non-parametric tests and Analysis of Variance (ANOVA) were used for analyzes. VO2peak and BMI were compared to historical data.

RESULTS

VO2peak increased significantly from admission to discharge but did not exceed historical data despite a minimal clinical important difference. BMI decreased significantly during rehabilitation (p < 0.001) followed by a significant increase after discharge (p = 0.006). There was a trend that people with American Spinal Injury Association Impairment Scale (AIS) D SCI increased lean mass to nearly normal values. Criteria for pre-diabetes or diabetes were present in 28.5% and dyslipidemia in 45% of the participants 44.2 days after time of injury.

CONCLUSIONS

Despite improvements during rehabilitation, outcome measures were worse than recommended, and most outcome measures worsened at follow up, even in people with an AIS D SCI. Meaningful support regarding exercise and diet when tackling altered life circumstances is needed after discharge.

Parasport: Effects on Musculoskeletal Function and Injury Patterns

➤

Sports participation can improve gait, muscle strength, and functional abilities in patients with a wide variety of disabilities. Para athletes are also at substantial risk for injury during sports participation.

➤

Ambulant athletes with cerebral palsy are at risk for soft-tissue injuries about the knee as well as foot and ankle injuries. Wheelchair athletes are at risk for osteoporotic fractures and shoulder girdle injuries. Limb-deficient athletes are prone to low back pain and overuse injuries of the contralateral extremity.

➤

Para athletes are vulnerable to abuse during sports participation, and physicians should promptly report any possible abuse or mistreatment.

➤

Orthopaedic surgeons should understand disability and sport-specific risk factors for injury in para athletes in order to initiate early management and injury prevention protocols.

Mental Health and Spinal Cord Injury: Clinical Considerations for Rehabilitation Providers

Purpose of Review

Assessing and addressing the mental and behavioral health concerns of individuals with SCI during rehabilitation is crucial, as untreated mental health distress can lead to reduced gains in rehabilitation and poor overall health. This review provides an overview of the latest research on prevalence rates of common mental and behavioral health concerns in the SCI population, highlighting disability-specific factors that may impact traditional assessment and treatment of mental health concerns.

Recent Findings

While those with SCI are at a heightened risk for experiencing mental health distress, overall, the majority of those with SCI adapt well, and live a full and meaningful life.

Summary

Rehabilitation psychologists are a vital aspect of rehabilitation teams, as they can address behavioral health and mental health concerns that may impede patients achieving their rehabilitation goals.

Exploring the contextual transition from spinal cord injury rehabilitation to the home environment: a qualitative study

Study design

Explorative qualitative study based on an interpretative phenomenological approach.

Objectives

This study explored the possibility of transferring knowledge and skills from a spinal cord injury (SCI) unit to the home environment; the individual and structural factors that potentially influenced this transfer; and its compatibility with a meaningful everyday life.

Setting

Hospital-based rehabilitation unit and community in Denmark.

Methods

Fourteen individuals with SCI were selected with maximum variation according to age, sex, marital status, and level of injury. In-depth, semi-structured interviews were conducted in the participants’ homes, 2–10 months after discharge from an SCI unit. Data analysis involved taking an interpretative phenomenological approach combined with a template analysis and applying the transfer of training theory to the discussion.

Results

Transitioning from the SCI unit to the home environment involved a multidimensional change of context in which most of the participants’ previous life roles had changed. This overarching theme had a decisive influence on: balancing loss and acceptance, facing external structural barriers, and the strength of social relationships when the knowledge and skills acquired at the unit were applied in a meaningful everyday life.

Conclusions

Transition from the SCI unit to the home environment is influenced by a multidimensional change of context that may restrict the use of acquired skills post-discharge, provide distant prospects for tertiary health promotion, and aggravate the experience of loss in people with SCI. Maintaining relationships is a strong mediator for transferring skills and re-establishing a meaningful everyday life.

The test-retest reliability of individualized VO2peak test modalities in people with spinal cord injury undergoing rehabilitation

STUDY DESIGN

Test-retest study.

OBJECTIVE

To describe the test-retest reliability of an individualized approach for peak oxygen uptake (VO₂peak) testing in a clinical context, accommodating inpatients with heterogeneous levels of physical functioning.

SETTING

Inpatient rehabilitation.

METHOD

Test-retest on two types of devices (recumbent stepper and arm-crank ergometer) with two predefined protocols of varying load increments on each device. No participants performed all four test modalities. VO₂peak, respiratory exchange ratio (RER), peak workload, and the reason for termination were reported. Of 23 participants included, 21 completed the test-retest procedure. Participants were inpatients, ≥18 years, who sustained a spinal cord injury (SCI) within the last 12 months at the time of admission. The median age was 52 years and 74% were male. Median time since injury at the time of the first test (T1) was 5.5 months. Seventeen were classified as American Spinal Injury Association Impairment Scale D. Intraclass correlation coefficients (ICC) and Bland-Altman plots for VO₂peak was calculated to determine intra- and intertester reliability of VO₂peak.

RESULTS

Mean VO₂peak obtained at T1 was 1.91 L/min (95%CI: 1.31-2.51); 1.26 L/min and 2.69 L/min for the recumbent stepper protocols; 0.61 L/min and 1.39 L/min for the arm-crank ergometer protocols. ICC for intra- and intertester reliability was 0.997 (95%CI: 0.986-0.999) and 0.994 (95%CI: 0.978-0.998) respectively. Bland-Altman plots showed a mean difference of -0.005 (SD 0,12) for overall test-retest.

CONCLUSION

Test-retest reliability was high. Mean VO₂peak at discharge from rehabilitation was higher than previously reported and individualized test modalities seemed to yield more optimal results in a heterogenous and representative sample during rehabilitation.

Mechanical stimulations can inhibit local and remote tumor progression by downregulating WISP1

Mechanical stimulations can prevent bone loss, but their effects on the tumor-invaded bone or solid tumors are elusive. Here, we evaluated the effect of knee loading, dynamic loads applied to the knee, on metastasized bone and mammary tumors. In a mouse model, tumor cells were inoculated to the mammary fat pad or the proximal tibia. Daily knee loading was then applied and metabolic changes were monitored mainly through urine. Urine samples were also collected from human subjects before and after step aerobics. The result showed that knee loading inhibited tumor progression in the loaded tibia. Notably, it also reduced remotely the growth of mammary tumors. In the urine, an altered level of cholesterol was observed with an increase in calcitriol, which is synthesized from a cholesterol derivative. In urinary proteins, knee loading in mice and step aerobics in humans markedly reduced WNT1-inducible signaling pathway protein 1, WISP1, which leads to poor survival among patients with breast cancer. In the ex vivo breast cancer tissue assay, WISP1 promoted the growth of cancer fragments and upregulated tumor-promoting genes, such as Runx2, MMP9, and Snail. Collectively, the present preclinical and human study demonstrated that mechanical stimulations, such as knee loading and step aerobics, altered urinary metabolism and downregulated WISP1. The study supports the benefit of mechanical stimulations for locally and remotely suppressing tumor progression. It also indicated the role of WISP1 downregulation as a potential mechanism of loading-driven tumor suppression.
