Summary: The study aimed to investigate the effect of hip actuation on upper extremity loading induced by crutches during ambulation with a Reciprocating Gait Orthosis (RGO). The results showed that hip assistance can significantly reduce upper extremity loading, which holds promise to promote long-term RGO use and enable more intensive rehabilitation training for patients with paraplegia.

Summary: This study aimed to evaluate the walking efficiency of lower limb exoskeleton gait orthosis and mechanical gait orthosis in patients with spinal cord injury. The results showed that both types of orthosis had positive effects on improving gait outcomes in patients. However, due to the diversity of study designs and methodologies, meta-analysis was not possible, and more high-quality studies are needed to confirm the findings.

Summary: This study presents a data-driven approach using wearable inertial sensors to assess walking patterns in spinal cord injury (SCI) patients. The results show that patients can be categorized into four groups based on walking speed and other gait parameters, and sensor-derived data can accurately predict future walking capacity.

Summary: This study compared the quality of life of patients with SCI wearing RGOs and HKAFOs, finding no significant difference in total scores but lower emotional stability and emotional independence scores in RGO users.

Summary: Spinal orthoses are effective in restoring the spine and controlling poor posture. This study found that wearing a spinal orthosis significantly reduced spine range of motion (ROM) compared to normal and poor posture walking. Furthermore, poor posture walking increased lumbar moments and back compressive forces, while walking with a spinal orthosis decreased trunk moments and reaction forces.

Summary: The study investigated the applicability of the Gait Deviation Index (GDI) in the population with Spinal Cord Injury (SCI). The results showed that GDI was normally distributed in both SCI and healthy volunteer groups. Furthermore, there was an increasing relationship between GDI values and the Walking Index for Spinal Cord Injury (WISCI) II levels in subjects with SCI, but only significant in WISCI II levels 13, 19, and 20. The index successfully distinguished the healthy volunteer group from individuals with SCI.

Summary: In this study, researchers proposed an adaptive assist-as-needed control system for assessing walking ability in patients undergoing robot-assisted locomotor training. The results showed that this approach can provide valid and reliable walking assessments for patients with different injury severity levels.

Summary: Spinal cord injury is a pathological process that affects the spinal cord and can alter motor, sensory, and autonomic function. This study evaluated the effect of a gait training program on patients with spinal cord injuries and found that it produced significant improvements regardless of the level of injury, sex, or functional class.

Summary: This clinical study aimed to determine and quantify the differences in gait characteristics between dogs with spinal ataxia and healthy control dogs using a computer-and treadmill-based gait analysis system. Dogs with thoracolumbar myelopathy showed higher variability in spatio-temporal and kinetic gait parameters mainly in the pelvic and thoracic limbs, but no effect on symmetry indices. Reduced peaks of ground reaction forces could potentially be explained by reduction of muscle strength or alteration of the rhythmogenic spinal circuits.

Summary: This study compared the center of mass (CoM) control during target walking (TW) task in individuals with incomplete spinal cord injury (iSCI) and healthy controls. The results showed that individuals with iSCI had impaired CoM movement when challenged with TW. The ability to cope with gait challenges worsened in individuals with higher levels of injury. This study demonstrated that TW task could be used as a gait challenge paradigm in ambulatory iSCI individuals.

Summary: The Gait Deviation Index (GDI) is a dimensionless measure used to evaluate overall gait pathology. It has been widely used in various conditions but has not been studied in the population with spinal cord injury (SCI). This study investigates the application of GDI in SCI and proposes a new metric, the SCI-GDI. The findings suggest that the SCI-GDI is more sensitive to larger gait impairment than the GDI and further validation is needed.

Summary: Robot-assisted gait training may be helpful in improving functional abilities and TUG (Timed Up and Go test) in patients with spinal cord injuries. However, its impact on gait distance, gait speed, leg strength, 10 MWT, and 6 MWT may be limited.

Summary: The sensor-based algorithm developed in this study for gait analysis in SCI patients is capable of measuring spatio-temporal parameters to track gait improvements. The algorithm performed similarly well for SCI patients and healthy controls in validation, covering diverse gait deficits from slow to preferred walking speeds.

Summary: A rope-pulley system can reduce metabolic cost during walking in healthy individuals, but it may affect walking balance, which is important to consider in gait rehabilitation.
