Walk Stronger
Recover Smarter
Lower body injuries often occur from a fall or while active in various different sports. Depending on the type of injury, a patient may be told to limit the amount of weight that can be applied during the recovery period.
Typically a weight-bearing protocol is prescribed. This is a structured plan that gradually increase the weight on the injured area as part of the rehabilitation process. These protocols are crucial for safe healing and regaining function.
Some common injuries that require a weight-bearing protocol include:
- A Tibial plateau fracture is a break or crack in the top, flat portion of the shin bone (tibia) that forms the lower part of the knee joint.
- A calcaneus fracture is a break of the heel bone, a large bone at the back of the foot.
- Meniscus root repair is a specialized surgical procedure used to treat a meniscus root tear, which is a tear at the point where the meniscus attaches to the bone in your knee.
These injuries can cause severve pain and instabilty if not properly treated.
Typical weight-bearing protocol for these types of injuries consists of:
-
Phase 1 (Weeks 0–6): Non-weight-bearing with crutches; limited range of motion.
-
Phase 2 (Weeks 6–12): Gradual increase in weight limit with greater mobility, and strength training.
-
Phase 3 (Weeks 12–24): Full weight-bearing, functional training, and return to activity.
Folllowing these weight-bearing limits is crucial for preventing long-term joint damage.
Unfortunately, over 35% of patients do not follow their prescribed weight limits and this increases to over 75% for the elderly. This can lead to an extended recovery times and in some cases, follow up surgery.
Up to now, there has been no effective and low-cost way to know when you have exceeded the limit.
Stay on Track
Recover on Time
The CastOff system lets you manage your recovery with confidence. The system is based on a smart-insole fitted in the patient’s shoe or walking boot and a small Pod attached to the patient's ankle.
The clinician, or caregiver will create a patient profile to set up the weight bearing protocol. This information is saved in the Pod
Once the set up is complete, a thin, light, smart-insole is placed the shoe which is connected to a small Pod placed around the ankle. The Pod will sound a tone and vibrate when the patient has exceeded their prescribed weight limit.
The PodTracker app is installed on the patient’s smartphone. This provides real-time indication of weight applied and shows the number of alerts and steps, A weekly chart shows all daily alerts and tracks the recovery progress
