Does Music Therapy Improve Gait after Traumatic Brain Injury and Spinal Cord Injury? A Mini Systematic Review and Meta-Analysis

Brain Sci., 2023 • March 21, 2023

This mini-review and meta-analysis investigated the impact of music therapy (MT) on improving gait in individuals with traumatic brain injury (TBI) and spinal cord injury (SCI). The meta-analysis reve...

KEY FINDING: MT shows positive effects on spatiotemporal aspects of gait in TBI, with medium effect improvements (Hedge’s g: 0.52).

Biomechanical evaluation of the hybrid pedicle screw—cortical bone trajectory technique in transforaminal lumbar interbody fusion to adjacent segment degeneration—finite element analysis

BMC Musculoskeletal Disorders, 2023 • June 24, 2023

This study used finite element analysis to compare the biomechanical effects of four different fixation techniques on adjacent segments after transforaminal lumbar interbody fusion (TLIF). The hybrid ...

KEY FINDING: Hybrid bilateral cortical screw - bilateral pedicle screw (CBT-PS) decreases the impact on adjacent segments after spinal fusion.

Control of center of mass motion during walking correlates with gait and balance in people with incomplete spinal cord injury

Frontiers in Neurology, 2023 • May 30, 2023

This study examined the relationship between control of lateral center of mass (COM) motion during walking and functional gait and balance measures in individuals with incomplete spinal cord injury (i...

KEY FINDING: Minimum lateral COM excursion had significant moderate correlations with BBS (ρ = −0.54, p = 0.014), TUG (ρ = 0.59, p = 0.007), FGA (ρ = −0.59, p = 0.007), 10MWT-preferred (ρ = −0.59, p = 0.006) and 10MWT-fast (ρ = −0.68, p = 0.001).

The biomechanical implications of neck position in cervical contusion animal models of SCI

Frontiers in Neurology, 2023 • June 6, 2023

This review addresses the variability in animal models of cervical spinal cord injury, focusing on the impact of head and neck positioning on biomechanics and outcomes. The review highlights that neck...

KEY FINDING: Neck position affects the exposed spinal level during contusion injuries, potentially causing variability in observed functional outcomes due to differences in the precise neurological level of injury.

Regulation of Bone by Mechanical Loading, Sex Hormones, and Nerves: Integration of Such Regulatory Complexity and Implications for Bone Loss during Space Flight and Post-Menopausal Osteoporosis

Biomolecules, 2023 • July 15, 2023

This review explores the complex regulation of bone integrity by mechanical loading, sex hormones, and neural elements, emphasizing their integration across the lifespan. The paper examines how these ...

KEY FINDING: Bone loss after spinal cord injury (SCI) is not solely due to disuse, suggesting a role for neural regulation.

Effect of respiratory muscle training on load sensations in people with chronic tetraplegia: a secondary analysis of a randomised controlled trial

Spinal Cord, 2023 • August 16, 2023

This study investigated the effect of respiratory muscle training (RMT) on load sensations in people with chronic tetraplegia. The results showed that RMT increased inspiratory muscle strength but did...

KEY FINDING: Respiratory muscle training (RMT) increased maximal inspiratory pressure (PImax) by 32% in the active group.

Biomechanical Analysis of Hybrid Artificial Discs or Zero-Profile Devices for Treating 1-Level Adjacent Segment Degeneration in ACDF Revision Surgery

Neurospine, 2024 • June 1, 2024

This study uses finite element analysis to compare different surgical revision strategies for adjacent segment degeneration (ASD) following anterior cervical discectomy and fusion (ACDF). The strategi...

KEY FINDING: The CDA-Cage construct demonstrated the lowest biomechanical responses and ROM ratio at adjacent segments among all RS models, closely approaching or even lower than those in the primary ACDF model.
