We report a case of postinfection sequelae in a patient presenting with subacute obstruction 2 months after COVID-19 infection. A 34-year-old man with a prior prolonged hospital stay due to COVID-19 complicated by upper gastrointestinal (GI) bleed presented with subacute obstruction and failure to thrive. Upper GI push enteroscopy revealed residual ulcers and multiple proximal jejuno-jejunal fistulae. Midline laparotomy revealed strictures with dense intra-abdominal adhesions, a large jejuno-jejunal fistula, and evidence of prior jejunal perforation following severe COVID-19 infection. The patient recovered after small bowel resection with anastomoses and was discharged home. Histopathological examination of resected specimen confirmed transmural infarction with evidence of prior hemorrhage, diffuse ulcers, and multifocal inflammation. This is the first report of a chronic GI sequelae resulting from COVID-19. As the pandemic evolves, medical professionals must be vigilant to consider alternative GI diagnoses in the COVID-19 survivors. People poststroke often walk with a spatiotemporally asymmetric gait, due in part to sensorimotor impairments in the paretic lower extremity. Although reducing asymmetry is a common objective of rehabilitation, the effects of improving symmetry on balance are yet to be determined. We established the concurrent validity of whole-body angular momentum as a measure of balance, and we determined if reducing step length asymmetry would improve balance by decreasing whole-body angular momentum. We performed clinical balance assessments and measured whole-body angular momentum during walking using a full-body marker set in a sample of 36 people with chronic stroke. We then used a biofeedback-based approach to modify step length asymmetry in a subset of 15 of these individuals who had marked asymmetry and we measured the resulting changes in
