Functional Electrical Stimulation

Neuromuscular Electrical Stimulation (NMES) is a way to use electrical impulses to artificially activate muscles that have been damaged due to stroke, spinal cord injury, or other various causes. Functional Electrical Stimulation (FES) is a type of NMES that can be used to activate muscles in order to perform a specific, functional task. For our research, we are interested in applying FES to help control muscle and joint stability in people with muscle weakness or other disabilities. We are currently developing experiments to see how FES can be applied practically to increase muscle stability.

Torso Instability

Low back pain (LBP) affects 80% of the US population at least once during their lives. It is the most common cause of job-related disability, and a leading contributor to missed work. LBP is often attributed to intervertebral ligament strain or intersegmental hypermobility associated with spinal instability.

The long term goal of this research is to develop better methods to prevent, diagnose, and treat spinal instability injuries and LBP. We are particularly interested in human movement and investigating how the body remains within the safe zone in order to prevent injuries. Safe zones are basins of stability (BoS) beyond which undesirable behavior occurs.

Characterization of the Meniscus

The meniscus of the knee is located between the femoral condyles and the tibial plateau and serves as a cushion to prevent bone to bone contact. The meniscus may be torn due to overuse or injury causing knee pain. If the tear is small it may be repaired surgically, but in some cases it must be removed. Following meniscus removal, a person is generally able to walk, but is at risk of developing osteoarthritis, a degenerative type of joint disease. The risk of developing OA may be reduced by replacing the meniscus with either an allograph or a tissue engineered material. Our research at WCU is focused on characterizing the material parameters of the meniscus and evaluating the performance of newly developed biomaterials.

Modeling Cancerous Tumors

Gliomas are a leading form of deadly brain cancer. Currently, there is no cure or remission status for malignant gliomas. In order to gain a better understanding of the progression of this disease, we created a hybrid compartment-continuum-discrete (CCD) model to simulate glioma growth and cellular invasion. The discrete portion of the model is capable of capturing intercellular interactions including cell migration, intercellular communication, spatial cell population heterogeneity, phenotype differentiation, epigenetic events, proliferation, and apoptosis. Combining this model with a compartment and continuum model allows for clinically significant tumor sizes to be evaluated. This mathematical model provides a means to evaluate the effect of various treatment options which may lead to improved treatments and outcomes for brain cancer patients. This research is in collaboration with the Department of Engineering Science and Mechanics at Virginia Tech.

Compression Garment Donning Device

Lymphedema is a medical condition caused by an excess of fluid collecting in the interstitial tissue. When the lymphatic system is functioning normally, the interstitial fluid passes into the lymphatic capillaries, thoughout the lymphatic ducts, and returns to the circulatory system. If this system is disrupted due to congenital reasons, surgery, or radiation therapy associated with cancer treatment, the fluid is unable to properly drain. This collection of fluid leads to swelling of the affected area which is generally controlled through the use of compression garments. However, these garments can be quite difficult to put on a limb. We have designed and built an assistive device to aid in this process (patent pending - details not disclosed due to intellectual property concerns). Our device was selected as a finalist in the undergraduate design competition at the ASME Summer Bioengineering Conference.

Manual Hoist

An undergraduate team has designed and built a manual hoist to assist people with disabilities. It is used to lift a person from a wheel chair to a bed, bath tub to a chair, etc. The project was developed for Technovashun, Inc, Chapel Hill, NC (patent pending - details not disclosed due to intellectual property concerns).

Powered Ankle Orthosis

People use a variety of assistive devices in order to make their everyday lives easier or to increase their natural capabilities. Medical conditions such as spin bifida, stroke, or spinal cord injuries can cause nervous system damage and lead to ankle weakness and an inability to walk effectively. In order to address this problem, we are developing a powered ankle orthosis to assist with plantar flexion. The project, still at the early stage, was started last semester by two undergraduate students. We have begun to develop the design of the power system and have created a mathematical model to simulate performance potential. Last semester our team won an award from the WCU Honor’s college which provided money to purchase raw materials for the research. More to come ...
