Medical Device Prototype for Planter Intrinsic Muscles: A Scientific Note

Abstract

Background: Intrinsic foot muscles are the contributors in the medial longitudinal arch and weakness of

these muscle contributes to range of foot deformities but the level of weakness is still unknown as there is

no valid and reliable method available to measure the strength of these muscles. Previous efforts to quantify

these muscle strengths were done like toe dynamometry, planter pressure etc. All such instruments made

do not consider two major biomechanical consideration 1. Position of Metatarsophalangeal Joint and 2.

Position of Ankle joint which is very important for keeping extrinsic foot muscle in disadvantage and no

effort was made to isolate the intrinsic muscle during measurement

Methods: The present prototype is designed to measure the forces of the planter intrinsic foot muscles

for research and clinical purposes All the considerations which was not taking care of in previous design

considered in the present design of our prototype.

Conclusion: Our device is one stop destination for the assessment and treatment of planter intrinsic muscle

where we can measure their strength and also strengthen them on the same platform by various exercises and

strengthening and therapeutic devices.
