Handb Clin Neurol, 2022 • January 1, 2022
The phrenic neuromuscular system, comprised of the phrenic nerve, phrenic motor nucleus, and diaphragm, is essential for breathing and other motor behaviors. The diaphragm must have high fatigue resis...
KEY FINDING: The phrenic nerve, which controls the diaphragm, is not uniform; the right and left nerves have differing compositions, with the right nerve containing more total axons.
Respir Physiol Neurobiol, 2022 • December 1, 2022
The study examined the phrenic-to-intercostal reflex during high-frequency spinal cord stimulation (HF-SCS) in C2 spinalized dogs to understand inspiratory muscle activation. Results showed that unila...
KEY FINDING: Unilateral diaphragmatic afferents reflexly inhibit motor activity to the ipsilateral EI muscles during HF-SCS.
J. Clin. Med., 2022 • August 24, 2022
The study aimed to assess the effect of a comprehensive rehabilitation nutrition program in cachexia and low muscle mass in motor-complete tetraplegia patients. A personalized rehabilitation nutrition...
KEY FINDING: 73.5% of patients were classified as obese upon admission, half were at risk of malnutrition, and 29.4% were compatible with cachexia.
The Journal of Spinal Cord Medicine, 2022 • January 1, 2022
This study investigated the relationships between body composition (%FM, %LM, and %FM to %LM ratio), inflammatory markers, and metabolic syndrome in individuals with chronic SCI. The results showed th...
KEY FINDING: Both higher %FM and lower %LM were associated with markers of inflammation (hs-CRP) and metabolic syndrome.
Frontiers in Rehabilitation Sciences, 2022 • May 13, 2022
The study compared soleus H-reflexes and posterior root muscle (PRM) reflexes during robotic-assisted stepping in individuals with and without motor-incomplete spinal cord injury (SCI). Results indica...
KEY FINDING: Both the soleus H and soleus PRM reflex amplitudes were higher relative to the non-injured group and modulated less during the step cycle in SCI subjects.
Am J Phys Med Rehabil, 2019 • November 1, 2019
This study investigated the influence of the level of spinal cord injury (SCI) on caloric intake relative to total daily energy expenditure (TDEE) and body composition (BC). It also aimed to develop a...
KEY FINDING: Individuals with tetraplegia had significantly higher total caloric, fat, and protein intake when adjusted for body weight compared to those with paraplegia.
Eur J Appl Physiol, 2019 • December 1, 2019
The study characterized left ventricular diastolic filling and volume during an exercise challenge in adults with incomplete cervical spinal cord injury (icSCI). The subjects with icSCI in this study ...
KEY FINDING: End-diastolic volume (EDV) was significantly reduced in icSCI compared to CON at peak exercise and at isomax.
Scientific Reports, 2019 • November 18, 2019
The study refines CMAP and MUNE methods for assessing spinal motor unit input in rat forelimbs and hindlimbs, demonstrating robustness and alignment with anatomical LMN counts. Validation in SOD1 muta...
KEY FINDING: CMAP and MUNE recordings are robust with low coefficients of variability in both forelimb and hindlimb of rats.
Top Spinal Cord Inj Rehabil, 2019 • October 1, 2019
This systematic review examined the use of electrophysiological (EP) outcome measures in spinal cord injury (SCI) clinical trials, revealing significant variation in assessment methods and reporting p...
KEY FINDING: The most commonly used electrophysiological measures were electromyography (EMG), motor evoked potentials (MEPs), somatosensory evoked potentials (SSEPs), and H-reflex.
PLoS ONE, 2019 • December 26, 2019
This study compared the recovery cycles of H reflexes and posterior root-muscle (PRM) reflexes in individuals with and without spinal cord injury (SCI). The findings indicate that PRM reflexes, but no...
KEY FINDING: The recovery cycles of H reflexes did not differ significantly between neurologically intact individuals and those with SCI.
