Article Synopsis
  • Adults with spinal cord injury (SCI) aged 45 and older often engage in low levels of leisure-time physical activity (LTPA), which can increase their risk of health issues.
  • In a study of 1,281 participants, nearly 44% reported no engagement in LTPA, with an average participation of about 197 minutes per week, with notable differences based on gender and type of injury.
  • The findings suggest a need for targeted initiatives to promote physical activity, particularly focusing on women and those with non-traumatic injuries in this age group.

Article Synopsis
  • The study aimed to explore Leisure-Time Physical Activity (LTPA) among individuals over 45 years old with spinal cord injuries (SCI), focusing on how frequently and intensely they engage in various activities.
  • Researchers examined data from 19 studies and 11 for in-depth analysis, finding that a significant portion (27%-64%) of this population does not partake in any LTPA at all.
  • Despite some participants meeting physical activity recommendations, notable differences were found in the frequency, intensity, and types of activities reported, indicating the need for better reporting and potentially more targeted interventions for this group.

Article Synopsis
  • FES cycling may improve muscle strength and fatigue resistance in individuals with spinal cord injuries, but measuring muscle fatigue during this process isn't well understood.
  • This study involved six participants with SCI who cycled for 30 minutes while using sensors to measure their muscle activity (MMG) and oxygen levels (NIRS).
  • The results revealed a moderate negative correlation between muscle activity and oxygen levels, with significant changes in these measurements before and after FES cycling, indicating that MMG could effectively track muscle fatigue and oxygenation during exercise.

People with spinal cord injuries (SCIs) often have trouble remaining active because of paralysis. In the past, exercise recommendations focused on the non-paralyzed muscles in the arms, which provides limited benefits. However, recent studies show that electrical stimulation can help engage the paralyzed extremities, expanding the available muscle mass for exercise.

Article Synopsis
  • A study compared virtual reality (VR)-enhanced indoor hybrid cycling with traditional outdoor cycling among individuals with chronic spinal cord injury (SCI), using a hybrid recumbent tricycle.
  • Results showed that oxygen uptake (VO) was higher during indoor VR cycling, and both arm and leg activity were significantly greater indoors compared to outdoors.
  • The combination of functional electrical stimulation (FES) and VR technology proved beneficial for physical activity promotion and rehabilitation in the SCI population, showing similar effort levels in both environments.

Heart rate variability biofeedback (HRV-F) is a neurocardiac self-regulation therapy that aims to regulate cardiac autonomic nervous system activity and improve cardiac balance. Despite benefits in various clinical populations, no study has reported the effects of HRV-F in adults with a spinal cord injury (SCI). This article provides an overview of a neuropsychophysiological laboratory framework and reports the impact of an HRV-F training program on two adults with chronic SCI (T1 AIS A and T3 AIS C) with different degrees of remaining cardiac autonomic function.

Objectives: This study was conducted to investigate the effects of combined progressive resistance training (PRT) and functional electrical stimulation-evoked leg cycling exercise (FES-LCE) on isometric peak torque and muscle volume in individuals with incomplete spinal cord injury.

Patients And Methods: In the single-blind, randomized controlled trial performed between April 2015 and August 2016, 28 participants were randomized between two exercise interventions (FES-LCE+PRT and FES-LCE alone), and training was conducted over 12 weeks. The isometric muscle peak torque and muscle volume for both lower limbs were measured at the baseline and after 6 and 12 weeks.

Background: Local muscle endurance (LME) is a significant indicator of muscle health and function in middle-aged and older adults. However, resistance training (RT) practices which optimise performance in this population are currently unclear. This study examined: 1) the effect of RT on LME; and 2) the impact of acute resistance exercise program variables on LME in middle-aged and older adults.

Background: Repetitive electrically-evoked muscle contractions lead to the early onset of muscle fatigue. This study assessed the relationship between muscle mechanomyography (%RMS-MMG) and tissue oxygen saturation (%TSI) in extensor carpi radialis (ECR) during electrically-evoked fatiguing exercise in individuals with tetraplegia.

Methods: Skin-surface mechanomyography (MMG) and near-infrared spectroscopy (NIRS) sensors were placed on the ECR of seven individuals with tetraplegia.

Despite developments in surgical techniques and medical care, people with a Fontan circulation still experience long-term complications; non-invasive therapies to optimize the circulation have not been established. Exercise intolerance affects the majority of the population and is associated with worse prognosis. Historically, people living with a Fontan circulation were advised to avoid physical activity, but a small number of heterogenous, predominantly uncontrolled studies have shown that exercise training is safe-and for unique reasons, may even be of heightened importance in the setting of Fontan physiology.

People with a Fontan circulation usually have moderately impaired exercise performance, although a subset have high physical performance ("Super-Fontan"), which may represent a low-risk phenotype. People with a "Super-Fontan" phenotype were defined as achieving normal exercise performance [≥80% predicted peak oxygen uptake (VO) and work rate] during cardiopulmonary exercise testing (CPET) and were identified from the Australian and New Zealand Fontan Registry. A Fontan control group that included people with impaired exercise performance (<80% predicted VO or work rate) was also identified based on a 1:3 allocation ratio.

Background: Arm crank ergometry (ACE), functional electrical stimulation leg cycling exercise (FES-LCE), and the combination of the two (FES hybrid exercise) have all been used as activities to help improve the fitness-related health of individuals with spinal cord injury (SCI). More recently, high-intensity interval training (HIIT) has become popular in the non-disabled community due to its ability to produce greater aerobic fitness benefits or equivalent benefits with reduced time commitment.

Objective: This thematic review of the literature sought to determine the potential benefits and practicality of using ACE, FES-LCE, and FES hybrid exercise in an interval training format for individuals with SCI.
