Clinical Trial: Powered Hip & Ankle Exoskeletons for Stroke Survivors With Gait Impairment
An exoskeleton device is a robotic system designed to improve an individual's ability to move and perform tasks encountered in everyday situations. These devices consist of external rigid limb segments that assists humans through different body movements with the use of actuators. These devices are controlled by an onboard computer that determines the timing and magnitude of assistance deployed to the user. Exoskeleton controller performance is key to providing beneficial assistance that does not inhibit the user's movement. Preceding work will compare the benefit of personalized hip versus ankle joint exoskeleton assistance for improvement of post-stroke gait. It will combine exoskeleton technology with the user's movement feedback to improve wearable robotic assistance to an individual stroke survivor's gait pattern. For the clinical trial research covered under this protocol, the investigator will test various exoskeleton technologies with stroke survivors in real-world contexts, indoors and outdoors, and measure clinically meaningful outcomes and user perceptions regarding technology usability and adoption. The long-term goal is to deploy self-adaptive, adoptable exoskeletons for personalized assistance during community ambulation.
Mechanisms of Fatigability and the Protective Effects of Exercise in People With Diabetes
Pre-diabetes (Pre-D) is a precursor to type 2 diabetes (T2D) and characterized by increased exercise fatigability of lower limb muscles, that can impede exercise performance. The cause for the increased fatigability in people with Pre-D is not known. Given the profound vascular disease present in people who have had uncontrolled diabetes for several years, we will determine whether dynamic, fatiguing contractions of the lower limb muscles in people with Pre-D are limited by vascular dysfunction at multiple levels along the vascular tree including the artery, arteriole, and/or capillary. This clinical trial involves a novel exercise training regime involving blood flow restriction to the exercising limb will be used as a probe to further understand the vascular mechanisms for increased fatigability in people with Pre-D and T2D. The long-term goal is to better understand what limits exercise and functional performance in people with diabetes to help develop targeted, more effective exercise programs.
Investigating the Impact of Ice Application on the Venous Puncture Pain in the Pediatric Population
the goal of this RCT is: "To evaluate the effectiveness of a non-pharmacological method (ice application) in reducing venous puncture pain among children aged 5 to 7 years.". An (RCT) will be conducted, involving 114 children, a non-probability convenience sampling will be used and children will randomly assign to two groups by lottery method. One group will receive ice application as an intervention, while other group will be control group, having no ice application.
