Gait analysis in hemiplegic stroke survivors who used the one-arm motorized walker.
CONCLUSION: The one-arm motorized walker may have a positive effect on the improvement of gait ability in hemiplegic stroke survivors. It can be an effective walking aid for hemiplegic stroke survivors who experience difficulties in independent walking. PMID: 31306144 [PubMed - as supplied by publisher]

Programmed Speed Reduction Enables Aortic Valve Opening and Increased Pulsatility in the LVAD-Assisted Heart
Aortic valve opening (AVO) during left ventricular assist device (LVAD) support aids in preventing valve fusion, incompetence, and thrombosis. The programmed low speed algorithm (PLSA) allows AVO intermittently by reducing continuous motor speed during a dwell time. AVO and hemodynamics in the LVAD-assisted heart were measured using a HeartMate II (Thoratec Corporation, Pleasanton, CA) LVAD with a PLSA controller in a mock circulatory loop. Left ventricle and aortic pressures, LVAD, and total aortic flow were measured during pre-LVAD, non-PLSA and PLSA combinations of cardiac function, and LVAD speed. The low cardiac setti...
