Comparing iWalk and Freedom Leg:
Which Hands-Free Knee Brace is Right for You?
“This internal evaluation trial was conducted at Gramercy Physical Therapy, under the supervision of Dr. Gene Shenker, DPT, MS, who served as the Principal Investigator. The study aimed to compare two hands-free knee braces, the iWALK and the Freedom Leg, to assess their effectiveness in patient rehabilitation.”
Recovering from a lower leg injury or surgery presents significant mobility challenges. Hands-free knee braces like the iWALK and Freedom Leg offer innovative solutions, allowing users to maintain mobility while keeping weight off the injured limb. While both devices aim to enhance the quality of life during recovery, they differ in design, functionality, and ideal use cases. Below is a detailed comparison to help you determine which option best suits your needs.
The iWalk is a hands-free crutch designed for individuals with below-the-knee injuries. It acts as a prosthetic extension of your leg, enabling users to walk with a natural gait while keeping their weight off the affected limb.
Key Features:
- Adjustable straps and height settings for a customized fit.
- Lightweight design (2.8 pounds).
- Requires no upper-body strength, unlike traditional crutches.
- Provides hands-free functionality, allowing users to carry out daily tasks.
- Independent EMG studies show that iWalk helps maintain muscle activity in the non-weight-bearing leg.
- Short training curve.
Best For:
- Injuries below the knee, such as foot fractures or Achilles tendon repairs.
- Active individuals with good balance.
- Quick set up and use.
Considerations:
- Requires good balance and strength in the uninjured leg.
- Not suitable for individuals with hip, knee.
- May require an adjustment period to learn proper use.
Freedom Leg Overview
The Freedom Leg is an offloading brace designed to redistribute body weight from the injured leg to the device, bypassing the need for crutches.
Key Features:
- Adjustable frame that fits a variety of body sizes.
- Redistributes weight to the user’s upper leg and torso.
- Mainly used for injuries below the knee.
- Comes in six different sizes for a more tailored fit.
Best For:
- Injuries to the knee, thigh, or lower leg.
- Individuals with limited upper body strength or poor balance.
- Longer recovery periods or those needing more stability.
Considerations:
- Heavier than the iWalk, weighing approximately 4.5 pounds.
- Less compact and more conspicuous.
- May feel bulky for users who are used to traditional crutches.
- Learning curve is more extensive compared to the iWalk.
- May require assistance and training for proper use.

Making the Right Choice
Choosing between the iWalk and the Freedom Leg depends largely on the nature of your injury and your physical capabilities:
Both devices provide innovative solutions to mobility challenges, empowering users to maintain independence during recovery. Consult your healthcare provider or physical therapist to determine which option is best suited to your specific needs.
- Opt for the iWalk if you’re recovering from a below-the-knee injury and are confident in your balance and strength.
- Consider the Freedom Leg if you need support for injuries above the knee or prefer a device that requires less balance and strength.
* After thoroughly comparing the iWalk and Freedom Leg across multiple key features, the iWalk’s advantages appear to outweigh those of the Freedom Leg in areas such as lightweight construction, self-installation, adjustability, and assured non-weight-bearing compliance.
