Benefits of Computerized Gait Analysis (In-Shoe Pressure Analysis)

Robert H. Sheinberg, DPM
Medical Director, Computerized Gait Analysis Services


The mechanics of the foot and ankle and their effects on the lower extremity and body as a whole are very intricate. Due to these complexities, it is sometimes difficult not only for the lower extremity specialist to have a precise and accurate measurement of these mechanics, but also a means by which to communicate, explain, or visually demonstrate to a patient what is occurring during the gait cycle. The F-Scan is a highly useful tool that provides a solution to this challenge.

The F-Scan is a noninvasive method whereby a paper-thin sensor is cut to width and length of a patient’s shoe and placed inside the shoe. The sensor then plugs into a small connector (paddle) at the ankle level. Thin sensor wires are plugged into the top of the connector paddle, which in turn connect to a computer, which contains sophisticated software that collects the and processes the data. The patient then walks in a straight line (or can be placed on a treadmill) and the computer will collect the data containing pressure measurements and the duration of the timing of those pressures. It is this data that the doctor then analyzes to determine abnormalities and develop an appropriate treatment regimen for the patient.

Many people can benefit from computerized gait analysis. Here are just a few examples:

1. Individuals with biomechanical abnormalities requiring conservative care such as orthotics, gait training, muscular re-education with target strengthening and/or stretching in physical therapy.

2. Individuals with biomechanical or structural abnormalities requiring surgical care; pre- and post-operative studies can be performed not only to assess the biomechanical results of the surgical procedure, but also to assess/regulate the amount of weight bearing taking place as well as gauge the progress of the rehabilitative efforts taking place in physical therapy.

3. Patients who need to be analyzed due to mechanical abnormalities as a result of traumatic or chronic injuries who may have chronic instability or lower extremity weakness.

4. Individuals with neuromuscular abnormalities as a result of systemic disease (diabetes mellitus with mixed motor and sensory neuropathy) or congenital conditions (cerebral palsy).

5. Individuals with deformities causing biomechanical abnormalities (limb-length discrepancy, scoliosis).

6. Patients who have not responded to their current treatment protocols for lower extremity ailments

7. People suffering from shin splints, stress fractures, foot pain, knee pain, hip pain, lower back pain, and muscular pain associated with poor mechanics of the feet.

8. Patients with residual disabilities as a result of accidents requiring a precise measurement of the difference in ability to bear weight on one extremity versus the other, henceforth providing the amount of disability a patient has

9.  Athletes attempting to maximize their performance potential

10. Patients, doctors, and physical therapists that desire the best possible care and treatment plan.


2D and 3D graphical representations of the foot precisely locate and record abnormal pressure distribution in real time, frame by frame. High-risk areas and abnormal gait can be instantly identified. The greatest benefit is that the patient can get a visual appreciation of their gait condition. Treatment can then be planned and executed accordingly. Post treatment F-Scan follow-up will substantiate the effectiveness of treatment.

South Florida Institute of Sports Medicine is proud to offer this state-of-the-art technology to their patients, as well as the offer an experienced physician in this field. Dr. Sheinberg has experience with this technology over the past 10 years dating back to his podiatric medical school education and continuing into his residency training and private practice, both in Pennsylvania and here in Florida. Dr. Sheinberg has already been solving biomechanical quagmires utilizing this technology and looks forward to challenging cases in the future.
