Article Abstract
BackgroundThe role of sensory pathways in gait recovery remains unclear. We hypothesized that preservation of the somatosensory pathway may play a key role in gait recovery in patients with stroke and severe motor pathway impairment.ObjectiveThis study aimed to investigate the impact of preserving the somatosensory pathway, spinothalamic tract (STT), and superior thalamic radiation (STR) on gait recovery in patients with chronic stroke and severe damage to motor pathways.MethodsThis retrospective cross-sectional study included 85 patients and investigated the association between functional ambulation categories and the integrity of sensory pathways, as represented by fractional anisotropy values. Diffusion tensor imaging was performed to assess the integrity of the corticospinal tract (CST), cortico-ponto-cerebellar tract, STT, and STR 6 months after stroke.ResultsMultivariable logistic regression analysis revealed that severe damage to the CST with the STT preserved yielded an odds ratio of 8.49 (p = 0.030) for functional gait, compared to when both tracts were damaged.ConclusionsSomatosensory pathways may play a critical role in gait recovery for patients with chronic stroke and severe motor tract damage. Preserving the somatosensory pathway could facilitate gait recovery in patients with severe motor pathway damage, offering valuable insights for future stroke rehabilitation strategies.

Vertebral compression fractures (VCFs) cause severe pain and functional impairments. Conventional treatments, including medication and vertebral augmentation, have limited efficacy and safety. Electroacupuncture (EA), which combines acupuncture with electrical stimulation, is a promising but under-studied approach for VCF management.

Effective locomotion requires physiological systems to adapt to instabilities. While gait perturbation recovery often appears rapid, it is possible that longer-lasting effects may be present. Therefore, this study explored recovery trends of gait dynamics following an experimenter-induced perturbation.

Massive weight loss after bariatric surgery frequently results in redundant abdominal skin that can compromise posture, gait, and joint biomechanics. This prospective study investigated the functional effects of circumferential lipoabdominoplasty in post-bariatric patients. Eighteen individuals (mean BMI 29.

Introduction: Deficits in lower-limb muscle strength and altered gait mechanics are common after anterior cruciate ligament reconstruction (ACL). While isokinetic strength testing is widely accepted in return-to-sport assessment, the role of plantar pressure analysis in detecting compensatory gait strategies remains underexplored.
Methods: This study included 10 male patients (30.
