About this study
The objective of this project is to fully test a newly developed affordable cost variable slip inducer in the ambulatory, incomplete spinal cord population. It is a self-contained device using a moving serial plank mechanism with wheels on the underside of each plank that allow for structured slips while a person walks over the planks with a harness for safety.
Read the detailed description
All planks appear the same but can be adjusted on the underside allowing for it to be stable or can allow a slip in the forward and/or backward direction of up to 8 inches. This distance was determined from a review of slip bio-mechanics that noted that a slip is likely to occur when a slip distance exceeds 10 cm (3.9 inches) with the probability of recovery decreasing as the distance increases. The first goal of the project is to determine the optimal distance required for individuals with incomplete spinal cord injuries to have a 50% fall rate, as healthy individuals were found to have a fall rate of 50% at 11 inches. Investigators will then look at common clinical assessments and examine their ability to predict an individual's ability to recover from the individual's identified optimal slip distance. Investigators will also look at within session training effect on a person's balance control following a training session using the device.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Slip TrainingDevice
-On a separate day (visit 2), using the identified optimal distance, a training session that involves 24 passes on the device where 1-2 planks move will be performed.
| Study group | Role | What they receive |
|---|---|---|
| Balance Slip | Experimental | * Perform standard clinical balance assessments
* Determine the optimal slip distance by 10 passes each with plank movement of 2", 4", 6" and 8" on visit 1 Receives: Device: Slip Training |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Static Balance
During the static stability test, the participants will be instructed to stand on the force plate as still as possible for 60 seconds with their eyes open. After 2 minutes of rest, the task will be repeated with the eyes closed. The excursions of the center of pressure (COP) and EMG of leg muscles will be analyzed.
The AMTI Force System from Water Town, MA will be used to for this test. The platform is placed on the floor and subjects stand on the device. The force plate measures the forces and movements applied to its top surface.
Measured: Assessment Session 1 (baseline test, Will occur at the start of Visit 1, Day 1), Assessment Session 2 (conducted before Training during Visit 2, Day 2), Assessment Session 3 (Post Training Assessment; conducted at the end of Training Visit 2, Day 2)
Change in Dynamic Balance
During the dynamic stability test, the ability to voluntarily displace the COP to a maximum distance without losing balance will be assessed (Limits of stability (LOS) test). The participant will be instructed to lean forward, backward, left, and right, hold the position for ~5 seconds and return back to the initial/center position.
