About

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.

Full 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.
