Parkinson's Projects


Parkinson’s disease (PD) is characterized by slowness of movement, flexed posture, and postural instability, which may lead to falls.
We are conducting studies to identify specific components of postural instability in people with PD, with an emphasis on characterizing how novel treatment strategies such as Osteopathic Manipulation can reduce falls.
Dr. Kendi Hensel and Dr. Rita Patterson are investigating the effects of Osteopathic Manipulative Medicine (OMM) in the treatment of persons with PD using state-of-the-art motion capture technology (CAREN, MotekForce Link).
It is anticipated that OMM can help improve postural control by reducing variations in body kinematics during gait and balance activities.

Hensel Web

Kendi Hensel, DO, Ph.D. is board-certified in FP/OMT and NMM/OMM. She has extensive experience in conducting and participating in studies on OMT. She is uniquely qualified to investigate the biomechanical effects of OMT and to translate those findings to clinical conditions that may be amenable to a comprehensive treatment program such as Parkinson’s Disease. She will be responsible for the overall management of the project as well as for the OMT interventions and reporting results.

Rita Patterson 2

Rita M. Patterson, Ph.D. is a biomedical engineer and has worked in clinical departments alongside clinicians applying engineering principles to solve clinical problems. She has extensive experience using motion capture technology to calculate human movement kinematics. She will be responsible for developing the protocol for kinematic collection, subject testing, analyzing data, and reporting results.

  • Effects of osteopathic manipulative treatment vs. osteopathic cranial manipulative medicine on Parkinsonian gait
    • This study aims to determine whether a single session of OMT or OMT + OCMM can improve the gait of individuals with PD by addressing joint restrictions in the sagittal plane by increasing the range of motion in the lower limbs.

  • Predicting UPDRS Motor Symptoms in Individuals With Parkinson’s Disease From Force Plates Using Machine Learning
    • The aim of this feasibility study was twofold. First, to evaluate quiet standing as an additional, out-of-clinic, objective feature to predict UPDRS-III subscores related to motor symptom severity; and second, to use quiet standing to detect the presence of motor symptoms.

Rehabilitation Projects

Rehabilitation Science is an interdisciplinary field of study that integrates knowledge from the basic and clinical sciences to improve our understanding of human movement, physical function, and disability across the lifespan and to improve outcomes for people living with disabilities.

  • Motion Assisted Hand Exoskeleton with Virtual Reality for Post-Stroke Rehabilitation (MAVHEXO)
    • Funded by NSF in collaboration with Dr. Muthu Wijesundara from the University of Texas at Arlington and Veena Somareddy from Neuro Rehab VR.
    • The aim of this project is to develop a new Virtual reality game integrating our hand exoskeleton with force-position control algorithms so that the hand-impaired community will have access to more engaging and consistent rehabilitation.
  • Soft-Robotic Glove for Cerebral Palsy Hand Rehabilitation (REHAB Glove)
    • Funded by NSF in collaboration with Nicoleta Bugnariu, UTA professors Muthu Wijesundara, Mahdi Haghshenas-Jaryani, and Katie (Wei) Carrigan, and Cook Children’s professor Pamela Sherman.
    • Many children with CP have some form of upper extremity limitations. Reduced function of the hands, hinders dressing, personal hygiene, and the use of assistive devices, resulting in greater dependency, restricted social participation, and a decreased quality of life. The aim of this study is to use soft robotic technology to develop a rehabilitation device that can provide continuous measurements and data monitoring, characterize the spastic resistance, and accommodate growth as needed. The REHAB Glove will fill an important gap to improve independence and reduce the burden of care.
  • Evaluation of a more sensitive measure for prediction of changes in dynamic postural stability and fall risk
    • Funded by an internal seed grant in collaboration with Dr’s Bugnariu and Papa.
    • Disordered health does not simply progress in one direction from the disease process to disability, to handicap; rather, the process is a complex interaction between health conditions, body structure and function, environmental and personal factors, and limitations in activity and participation. Falls are the consequence of many factors, thus a system approach is necessary to determine the root cause. Thus there is an interest and need to validate a measure to capture the interplay between postural control and instability as an indicator of disability during functional tasks. We propose to investigate the relationship between the Center of Pressure (COP) and Center of Mass (COM) of the body as a more sensitive measure of this process.
