The Effects of a Powered Hip Flexion Orthosis on Gait in Persons With Multiple Sclerosis: a Case Series
University of Dayton
Summary
The purpose of this study is to assess the immediate effects of a commercially available non-FDA regulated powered hip flexion assist device (Hypershell X, Shenzhen, China) on walking ability in persons with MS. The main question it aims to answer is: Does a powered hip flexion device provide immediate improvements in walking ability over short distances for people with MS?
Description
Individuals with multiple sclerosis (MS) frequently experience problems with walking that may include difficulty with advancing the leg during the swing phase of gait which can lead to a loss of independence and a higher risk of falls. To improve walking ability in this population, devices such as ankle-foot orthoses (AFO) and functional electrical stimulation (FES) are commonly used. However, recent advances in technology and robotics have led to the development of affordable and commercially available battery powered exoskeletons marketed towards improving activities such as hiking, running…

Interventions
- DevicePowered Hip Flexion Orthosis (Hypershell X)
Participants will perform a series of 10 meters walks while wearing the hip flexion assist device under the following conditions. 1) No assistance (passive mode) 2) 25% power assistance 3) 50% power assistance 4) 75% power assistance During the trial subjects will wear motion sensors that provide the following gait parameters: speed, step and stride length, foot clearance, foot angle at heel strike, circumduction, single and double support time.
