Improving Asymmetry during Gait using the Force-Time Graph in F-Scan
by Norman Murphy, Ph.D.
When symmetry in foot function during gait is perturbed, undesired torque can be generated, and stress is
transmitted along and within the tendons and muscles, ligaments and bones. Torque and stress are
mechanical components that for which continuous over-time, wear and tear body tissues, thus potential
causes for symptoms of discomfort and pain.
Asymmetry in gait can be measured using F-Scan®. Symptoms associated with gait asymmetry include:
Left knee pain when running
Stiff big toes when walking.
Calluses on medial side of big toe.
Measure asymmetry, act on the cause, and eliminate symptons of discomfort and pain using F-Scan.
