Community Mobility after Stroke Using Smartphones
Mobile smartphones are essentially a highly functional wearable sensor. Individuals with stroke carry a smartphone while going about their daily lives to tell us about their behavior.
Project
RIC Arm
Current motorized prosthetic arms are heavy and can be burdensome. The RIC Arm is specifically designed to be much smaller and lighter than currently available prostheses.
Project
Improving Control of Robotic Hand Prostheses
A computer algorithm can learn patterns and determine what movement the user intends to make. The user can thus control the prosthesis—and perform a variety of hand movements—just by attempting to make the desired movement.
Project
Intramuscular EMG Signal Processing
While surface electrodes are inexpensive and non-invasive, they are also prone to muscle cross talk—EMG signal contributions that originate from muscles but are not directly under the electrodes and electrode shift.
Project
Targeted Muscle Reinnervation
During TMR nerves in an amputee’s residual arm are transferred to target muscles that no longer perform a useful function because of the amputation.
Project
Targeted Reinnervation for Below-Elbow Amputation
The objective of this study is to quantify the effect of TMR on persons with below-elbow amputation
Project
Manual Standing Wheelchair
Researchers at the Shirley Ryan AbilityLab have designed the first-ever manual standing wheelchair that allows users to be mobile in both sitting and standing modes.
Project
Altering Activation Patterns in the Distal Upper Extremity After Stroke
This study evaluates a new rehabilitation approach for stroke survivors in the chronic phase of recovery in which the combination of drug therapy (cyproheptadine) and active movement practice (AMP) is used to encourage increased voluntary muscle control and strength.
Project
Motor Impairment Related Changes in Muscles Properties in Chronic Stroke
We're interested in understanding whether the chronic neural impairments and disuse of the upper limb associated with hemiparetic stroke lead to changes in muscle structure that significantly change the muscle's ability to generate force, creating additional difficulties for use of the hand and arm.
Project
Intraoperative Sarcomere Length Measurements
We have found that spastic muscle, although having a normal stretch reflex, has a significantly higher intrinsic muscle stiffness compared to control muscle.
Project
Relationship Between Intramuscular Pressure and Muscle Force
We are developing a minimally invasive tool to measure muscle force using fiber optics.
