Activity-specific aquatic therapy targeting gait for a patient with incomplete spinal cord injury.

INTRODUCTION: Aquatic therapy can lead to improved mobility and health in individuals with various conditions. This case report looks at an activity-specific aquatic therapy targeting gait for a patient with incomplete spinal cord injury (iSCI). CASE REPORT: The patient participated in an individualized aquatic therapy program two times a week for 6 weeks. Assessment occurred prior to the intervention. There were two follow-up assessments after the intervention. Follow-up assessment 1 was completed within the same week as the final intervention. Follow-up assessment 2 was completed 4 weeks after the first follow-up to assess for carryover. RESULTS: Improvements that met minimal detectable change and minimal clinically important difference were noted in The Walking for Spinal Cord Injury Index-II, Spinal Cord Injury Functional Ambulation Index gait parameters, and gait speed. DISCUSSION: An activity-specific aquatic therapy program improved gait in a patient with iSCI. The properties of water create a practical environment for safe practice of skills. Further studies are warranted in large samples.

Bacterial DNA and RNA induce rat cardiac myocyte contraction depression in vitro.

Sepsis and septic shock, the systemic immunologic and pathophysiologic response to overwhelming infection, are associated with perturbation of a variety of metabolic cell pathways and with multiple organ failure (MOF) including cardiac depression. This depression has been attributed to the effect of several circulating and locally produced proinflammatory mediators. Recent data suggest that bacterial nucleic acids can produce profound systemic inflammatory responses characterized by circulatory shock in intact animals. In this study, bacterial DNA and RNA derived from pathogenic clinical S. aureus and E. coli isolates are shown to induce early concentration-dependent depression of maximum extent and peak velocity of contraction of electrically paced neonatal rat ventricular myocytes in culture. Significant but more modest depression was generated by a nonpathogenic E. coli isolate. Pretreatment with a DNase or RNase abrogated this effect. Further, synthetic, double-stranded RNA (dsRNA) also induced concentration-dependent depression of myocyte contraction, with the effect also being prevented by pretreatment with RNase. These data suggest that bacterial DNA and RNA may contribute to myocardial depression during bacterial sepsis and septic shock.
