Application 157 - Robotic Leg Rehabilitation Device

Application Summary

The loss of walking is certainly devastating to an individual. Gait training and rehabilitation are not modern concepts, but through modern technologies, engineers and researchers are working on developing exoskeletons to help rehabilitate a patient at a more accelerated pace. Critical line tension force measurements are gathered during development of motor-assisted exoskeletons to ensure that proper assistance is given at different stages of treatment.

Products in Use

JR S-Beam Load Cell (LSB200) paired with instrumentation (USB220 and IAA Series analog amplifiers).

How it Works

1. The LSB200 JR. S-Beam load cell is mounted inline of the tension wire.
2. The LSB200 load cell will measure tension forces while patient’s legs while walking/moving.
3. Measurement feedback collected from the LSB200 can be used to diagnose the current status of the patient and track future improvements.
4. These measurements can be streamed from the USB220 up to 4,800 samples per second to a PC for data capture and analysis.
5. Or the the load cell outputs can be amplified to a PLC with the IAA Series analog amplifiers.

Application Summary

Bionics is now science fact! Researchers, doctors, and engineers are creating ways to help patients speed up rehabilitation by allowing them to perform more tasks on their own. In the application below, the LSB200 load cell is small enough to mount to the cabling a bionic glove, tasked to measure the forces of the simulated tendons on the hand. From the data measured, a patient may obtain a glove tailored to their assistance level.
