For hospitals’ rehabilitation departments & patients after lower limb injuries to increase patient compliance and expedite their recovery
Patient adheres to WB program using feedback cues from tips and app. Data is sent to doctor’s phone and PC
Doctor sets weight bearing (WB) program for duration of patient’s recovery
Patient adjusts the load on injured leg according to doctor’s instructions
Doctor monitors how the patient loads the injured leg, addresses patient concerns, and adapts program to patient’s needs

The AO protocols for trauma aftercare formulated 50 years ago. They suggest restricted NO WB for 12 weeks. To optimize it, Early and Permission WB were designed
PWB might be implemented in trauma patients with fractures of the pelvis and lower extremities.
EWB can be considered safe and effective in selected cases. Level of evidence Therapeutic Level III.
Early and PWB leads to 6-8 weeks faster rehabilitation, without complications
The median time to full WB was 12 weeks (for 78 patients with PWB protocols) instead of 20 (for 78 patients with old AO protocols)
However, 87% of doctors don’t prescribe Early or PWB
11.7% – started immediately with weight bearing,
4.5% – after 2 weeks
55.9% – recommended starting WB 6 weeks post-operatively.
15.3% – after 12 weeks
Because doctors understand – patients can’t follow PWB protocols without a biofeedback device
Meanwhile, the biofeedback device is superior method in helping patient complaining with Early or PWB
A strong immediate effect on partial weight-bearing compliance which effect lasts up to 24 hours and effective way to train patients to comply with weight bearing
12 participants were trained with a biofeedback device to comply with touch-down weight-bearing instructions (25 lb). Following initial biofeedback training at 25 lb, participants bore an average of 20.4±2.12 lb.
The ComeBack Mobility crutch tip system should be considered for clinical use as a valid tool
CBM device provides 0.5-1% of accuracy measure between 10% and 50% of partial weight-bearing

“It gives them immediate feedback and teaches them had to weight bear properly and follow up the follows a program that I prescribed gives me feedback”
CSU Prof. & Assoc. Director Physical Therapy
“It gives everybody an opportunity to just have some more feedback”
Maastricht University Medical Center, the Netherlands. Does research in Surgery and Traumatology. Current project – ‘Permissive weight bearing’
“With the feedback patients gets from the Crutches, they will back to walk 8 weeks sooner”

“The biggest issue for me is that people aren’t listening, so it’s an issue of not enough pressure or too much pressure. With teenagers it’s a little bit less of «too much», it’s a matter of putting enough weight to it, so I can track it. I can see their percent, so when they come I can say: «Hey, you are not doing enough. You’ve make a thousand steps the first week and week 2 you kinda fall off. You have to stop your game up and get more compliance to put more pressure or ask them not to put too much pressure”
PT, DPT, CSCS, USAW, SFMA, TPI, Clinical Director Professional Care Physical Therapy
“The issue arise is that one the patient foot is out of the scale, really there is no other way to tell how much weight they are actually putting. There is no objective medical founded”

The idea of attaching Smart Tips to crutches was tested with real patients, and unlike insoles, Smart Crutch Tips are:
1. Always with the patient, even at night, when the patient is barefoot
2. More durable – 3 years of use
3. Available to consumers of any age and shoe size
4. More affordable to implement
5. Fit the reusable model
When walking on crutches, there is a moment during which the healthy leg is completed lifted off the ground and the entire load is distributed between the crutches and the injured leg.
We can determine how much load is placed on the injured limb by subtracting the amount of weight on the crutches from the patient’s body weight. For example: if a patient’s weight is 80 kg and during a step he transferred 60 kg to crutches, then 20kg of pressure was exerted on the injured limb.
The error of weight sensors is less than 100 grams. We have calculated everything for safe use and a speedy recovery
The amount of initial weight bearing can be set from 0% NWB to 50% PWB. The upper threshold for graduated WBAT is 80%.
The Smart Crutch Tips device can be used by patients recovering from nonsurgical and surgical treatments for hip, thigh, knee, shin, ankle, and foot injuries and pathologies
Yes! A patient can begin their gait rehabilitation on crutches and progress to a cane for quality gait progression
