TripleFlex treats foot drop and leg-lift deficiency by flexing each joint during the swing phase of gait.

TripleFlex is an innovative device that corrects hip, knee, and foot drop while putting energy into the patient’s step.

Foot drop is a common problem in patients with neurological conditions such as multiple sclerosis, brain injury and stroke. Foot drop is a condition in which the muscles of the foot allow it to drop down when walking. Patients with foot drop are at risk of tripping and falling.

Neurological conditions can also weaken the hip and knee flexors – it's called hip and knee drop, or leg-lift deficiency. When all three joints lack proper control, walking becomes extremely difficult and taxing.

Traditional foot drop correction involves bracing the ankle and foot, limiting motion and forcing patients to wear shoes. TripleFlex may allow some patients to walk without an orthosis or even shoes.

TripleFlex may be useful in patients with leg paralysis resulting from:

  • Spinal Cord Injury
  • Stroke
  • Multiple Sclerosis
  • Cerebral Palsy
  • Traumatic Brain Injury
  • Flaccid Paralysis

TripleFlex can be adjusted to correct inversion of the foot by increasing tension in the lateral foot strap.

How TripleFlex Works

How to put on your TripleFlex

Walking is one of the more simple joys of life.


TripleFlex adds energy to walking while liberating joints. It is easy to put on and comfortable to wear.

Ask your local physical therapist or orthotist to set up an evaluation to determine if you are a candidate for TripleFlex.

The TripleFlex bilateral belt can correct hip, knee, and foot drop in both legs.

TripleFlex Now Available in Canada

We are pleased to announce that AxioBionics is now authorized to sell its TripleFlex product in Canada. We look forward to serving our neighbors to the north and will be actively seeking partners to conduct clinical evaluations for our TripleFlex product.

Request an evaluation to see if TripleFlex or one of our other foot drop options is appropriate for you.

TripleFlex eligibility can only be evaluated by a physical therapist or orthotist.


"I tried multiple orthotics for foot drop, but they were uncomfortable and didn't address my hip drop.  Even with orthotics, my walking was labored and very tiring because I couldn't lift my leg from the ground.

TripleFlex picks up my entire leg, and I can walk longer distances without fatiguing.  I feel like I'm back to relying on my left leg for support so my right leg doesn't have to work as hard."

For Clinicians Interested in Learning More about TripleFlex™:

For Orthotists:

TripleFlex can add a new dimension to your practice of orthotics. With TripleFlex, you will be able to offer your patients a mechanism for assisting hip flexion in the swing phase of gait that may reduce energy consumption while boosting ground clearance. TripleFlex can add confidence to the patient’s step.

TripleFlex can be applied over the patient’s leg and orthosis or directly attached to an AFO. TripleFlex can be used with a variety of footwear or without a shoe, in appropriate circumstances.

From the Experts

"As a licensed physical therapist who specializes in treatment of patients with Multiple Sclerosis (MS), I am challenged by the varying symptoms and physical impairments that I am trying to treat. Many people with MS suffer from leg weakness and related walking difficulties. Whereas the most common weakness related diagnosis is foot drop, there are a high number of patients with foot drop who also have limited hip flexion.

Limited hip flexion in patients with MS is hard to treat since traditional strength training is not effective for long term changes. Strengthening exercises for the hip do not usually result in consistent gait improvements. For patients with hip flexion limitations, many times their leg may only lift a small percentage. For these patients, supplementation through bracing allows patients to get more out of each of their efforts to take a step. Ankle foot orthoses and similarly functioning devices have been a staple to treat foot drop for many years. I am excited that there is a new device to help hip flexor weakness that can be used with or without shoes and can be isolated to address the hip weakness.

TripleFlex is the newest device that I have had the pleasure to prescribe for my patients with hip flexor weakness and foot drop. What is so special about this device, is that patients can continue using their own AFO (to treat the foot drop) while TripleFlex treats the hip weakness or, TripleFlex can be used to manage both hip weakness and foot drop. With patients reporting comfort and ease of use, TripleFlex has become the primary treatment option at my office for patients who have difficulty walking due to hip flexor weakness.

I have seen improvements in walking, exercise compliance, and balance strategies with the use of TripleFlex. Physical therapists and wellness professionals who work with people with neurologic conditions should consider TripleFlex as an option for functional strengthening and training for people with hip flexor weakness and foot drop.”
