Официальное название

Balance4Mobility: Effects of Walkasins Use on Clinical Outcomes of Gait and Balance Function in Individuals With Peripheral Neuropathy and Balance Problems - A Randomized Control Trial

Обзор

The goal of this clinical trial is to is to test whether Walkasins can help people with peripheral neuropathy maintain their balance better. The main question it aims to answer is whether participants who use Walkasins on an everyday basis over a six-month period will report better awareness of their foot placement on the ground. Researchers will compare Walkasins users to a control group of participants who are not using Walkasins to see if the device improves the users' performance on some standing and walking tests. Control group participants will get Walkasins after six months of being in the study. During the study participants will be asked to do the following: * Answer questions about their medical history and balance. * Do some standing and walking tests. Some of the tests will be timed. * Attend study visits and participate in study phone calls. * Keep track of any falls and notify study staff if they fall. * Wear the Walkasins device on a regular basis.

Подробное описание

A randomized cross-over study of short-term, in-clinic effects of Walkasins use, conducted at the Minneapolis Veterans Affairs Medical Center (VAMC) and published in PLOS ONE, found clinically meaningful and statistically significant improvements in gait speed and functional balance in patients with SPN using Walkasins. The authors stated that "findings suggest new sensory balance cues provided to the lower limb can modulate the activity of relevant nerve afferents and become integrated into sensorimotor control of balance and gait."

In 2020 a multi-site clinical trial of the long-term effects of daily Walkasins use (walk2Wellness, ClinicalTrials.gov #NCT03538756) was published in Frontiers in Aging Neuroscience. After 10 weeks of Walkasins use, this long-term study demonstrated clinically meaningful improvements in Functional Gait Assessment (FGA) and gait speed, which is associated with a lower fall risk. The authors concluded that "a wearable sensory prosthesis may provide a new way to treat gait and balance problems and manage falls in high fall-risk patients with PN."

Most recently, an analysis of data from 26 weeks of Walkasins use in the walk2Wellness trial showed that "participants who reported falls over 6 months prior to the study had a 43% decrease in fall rate during the study as compared to self-report 6-month pre-study (11.8 vs. 6.7 falls/1000 patient days, respectively, p \<0.004), similar to the 46% decrease reported after 10 weeks of use."

The present study involves an assessment of Walkasins through a randomized, controlled trial with a primary endpoint of 26 weeks. Furthermore, this study will enroll only individuals 55 and older with a goal of including participants that reflect the Medicare population to support payer reimbursement for Walkasins.

The objectives of this study are as follows:

* Reflect real-world use of Walkasins in a Medicare-representative population who have sensory peripheral neuropathy and associated gait and balance problems and who would be eligible for a prescription to use the device. * Investigate the impact of Walkasins use on relevant clinical outcomes associated with gait and physical function. * Demonstrate based on patient reporting that Walkasins improves awareness of foot placement on the ground indicating partial replacement of plantar mechanoreceptor function, lost due to peripheral neuropathy. * Investigate whether plantar monofilament testing at levels \<10g (5.07, LOPS) are associated with gait and balance issues. Is there a Loss Of Balance Sensation (LOBS) threshold that is \<10g? The monofilament test protocol should include plantar sites across the foot since differences in anteroposterior and/or mediolateral sensitivity may cause balance issues. * Compare the rate of injurious falls between a group of Walkasins users and non-users over a six-month period.

Вмешательства

• Устройство Walkasins
  Walkasins® is an external, lower limb sensory prosthesis intended to replace part of the nerve function used for detection and signaling of foot pressure sensation during standing and walking activities. Walkasins consist of two parts for each leg: the Haptic Module and the Receptor Sole. The Haptic Module wraps around the lower leg of the user and contains electronics for reading Receptor Sole pressure signals, a microprocessor, and four vibrating motors that provide gentle tactile sensory cues
• Другое Fall Prevention Training
  Participants will watch "6 Steps to Prevent a Fall," a short (2 minute) educational video from the National Council on Aging, which describes simple steps to reduce fall risk. To improve their access to the education provided, participants will also receive three handouts, produced by the Center for Disease Control and Prevention (CDC) STEADI initiative (Stopping Elderly Accidents, Deaths, and Injuries), to review after the study visit. The STEADI Initiative is a coordinated approach for healthc
