Medical Device Prototype for Planter Intrinsic Muscles: A Scientific Note
Keywords:Ankle Joint, Metatarsophalangeal joint, Planter intrinsic muscle, Toe dynamometry
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.
