Portable Limb Load Monitor_Touch (PLLM_Touch)
How it Works
How to use the PLLM
A poll was recently taken from users and prescribers of rehabilitation equipment at the Virtual Disability Expo 2020.
Question: When do you like getting feedback?
- 67% would like feedback immediate (in real time) whilst doing the challenge.
- 33% would like feedback at the end of a challenge, coming from their doctor / therapist.
Our organisation uses the latest PLLM_Touch regularly for patients with acquired brain injury to improve their balance and gait

This biofeedback unit is designed and developed to comply with International Standard ISO 60601
Immediate audio and visual biofeedback on weight bearing motivates patients to reach their treatment goals faster.
- Monitoring gait and movement
- Monitoring balance after stroke
- Gait rehabilitation in stroke patients
- Gait retraining
- Rehabilitation following acquired brain injury
- Rehabilitation for neurological conditions
- Weight bearing compliance after orthopaedic surgery
- Rehabilitation for amputees
Immediate audio and visual feedback
Ultra thin weight sensing heel and forefoot pads give reliable and accurate feedback on weight bearing during gait, standing, sit to stand and reaching activities.
The PLLM_Touch is an effective tool to assist the therapist to objectively verify whether a patient is loading the appropriate percentage of body weight through the affected limb. It is intended to enhance, not replace existing therapy.
The PLLM_Touch may assist with rehabilitation following an acquired brain injury such as stroke, neurological conditions, lower limb amputation or orthopaedic surgery.
Easy to set up
Each Unit comes with foot insoles of various sizes to support the weight sensing heel pad and forefoot pad. The sensors pads are placed onto an insole and inserted into the patient’s shoe on either the affected or unaffected side. The pads are then attached to a node and strapped to the lower leg. Data is transferred wirelessly from the node to the Control Unit.
Setting the target
Changing the settings can be used to encourage or restrict weight bearing.
- Alert Before Target mode – patient gets feedback when weight to the selected limb is below the target.
- Alert After Target mode – patient gets feedback when weight to the selected limb is above the target.
After choosing the mode, the therapist can set the target weight with one touch on the LCD screen. The target can be adjusted “on the fly”. There is a “HELP” feature available with most screens to assist therapist.
Our latest design allows the target to be set either as a level or as a percentage of total body weight.
The patient receives feedback when the weight through their selected limb is either below or above the target. Feedback is given via the speaker or headphone. There are separate touch screen controls to adjust the volume for the speaker and headphone. Two yellow and two red LEDs to indicate how far the patient is above / below target.
At the end of a training session, a four column bar graph represents the number of seconds each LED was “on” giving immediate feedback to patient and therapist on overall performance.
"Standardized instruments for measuring the intensity of balance exercises in clinical environments are lacking"
