About this study
Official title: Evaluation of the NEUROSWING Orthosis on Walking Speed in a Population With Dorsal and/or Plantar Flexor Deficits, With a View to a Reimbursement Application. Clinical Investigation: NS-BOOSST
The aim of this randomized, cross-over, multi-center, intention-to-treat, open-label study study is to determine the benefits of the NEUROSWING device on gait speed in patients with dorsal and/or plantar flexor deficits, compared with the use of a carbon orthosis. Each patient will benefit in random order from a 14-day investigation period with the NEUROSWING device and a 14-day control period with a carbon orthosis. These two 2-week periods will be separated by one week, during which no orthosis will be worn and no evaluation will be carried out. Patients will be randomized to determine which phase they will start with. The primary endpoint is walking speed, which will be measured by comparing the results of the 10-meter walk test. For the secondary endpoints, patients will be assessed using the Functional Gait Assessment (FGA), the 6-minute test and an analysis system that will analyze other gait parameters (duration of the different phases of the gait cycle, cadence and step length). In order to carry out the assessments, each patient included will have 12 visits spread over 5 weeks.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
NEUROSWING Orthosis (experimental) : carbon orthosis with an active ankle articulationDevice
The patients will use the experimental device during 14 days straight as well, then a washout period of 7 days with no interventons and then the comparator during 14 days straight. The order in which they will use each device will depend on the groupe they have been randomized in :
- Arm 1 : Control device during 14 days, followed by a 7 day washout period, then exerimental device during 14 days
- Arm 2 : Experimental device during 14 days, followed by a 7 day washout period, then control device during 14 days
Carbon orthosis (control)Device
The patients will use the experimental device during 14 days straight as well, then a washout period of 7 days with no interventons and then the comparator during 14 days straight. The order in which they will use each device will depend on the groupe they have been randomized in :
- Arm 1 : Control device during 14 days, followed by a 7 day washout period, then exerimental device during 14 days
- Arm 2 : Experimental device during 14 days, followed by a 7 day washout period, then control device during 14 days
| Study group | Role | What they receive |
|---|---|---|
| Condition A | Active comparator | Condition A corresponds to the control phase where the patient will use the control device during 14 days. Receives: Device: Carbon orthosis (control) |
| Condition B | Experimental | Condition B corresponds to the experimental phase where the patient will use the experimental device during 14 days. Receives: Device: NEUROSWING Orthosis (experimental) : carbon orthosis with an active ankle articulation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Walking speed : 10m walk test
Measured: At all 12 visits from baseline (day 1), to end of study (day 35)
Secondary outcomes (3)
Functional Gait Assessment (FGA)
The Functional Gait Assessment (FGA) is a modification of the Dynamic Gait Index (DGI) that uses higher-level tasks to increase the applicability of the test to people with vestibular disorders and to eliminate the ceiling effect of the original test. Three items were added to the DGI because these were noted to be difficult in people with vestibular disorders.
The FGA is used to assess postural stability during various walking tasks :
- Gait on a Level Surface
- Change in Gait Speed
- Gait with Horizontal Head Turns
- Gait with Vertical Head Turns
- Gait and Pivot Turn
- Step Over Obstacle
- Gait with Narrow Base of Support
- Gait with Eyes Closed
- Ambulating Backwards
- Steps
Measured: At baseline (day 1), day 14, day 22 and end of study (day 35)
6 minute walk test
Measured: At baseline (day 1), day 14, day 22 and end of study (day 35)
Spatio-temoral gait analysis
Measured: At baseline (day 1), day 14, day 22 and end of study (day 35)
