Abstract
Physical rehabilitation aims to help people recover their mobility and strength after an
injury or illness. One way to evaluate progress in rehabilitation is through isokinetic prototype
tests that describe the dynamic characteristics of an isokinetic leg extension device for
rehabilitation and control action. These tests use an isokinetic system to assess muscle strength
and performance in a patient during isometric or isokinetic contraction. An experimental
prototype allows the performance of the device to be evaluated in a controlled environment prior
to use by the patient. In order to achieve physical recovery from musculoskeletal injuries in the
lower limbs and achieve the reintegration of the affected subject into society as an independent
and autonomous individual in their daily activities, a control model is presented that introduces a
medical isokinetic rehabilitation protocol, where the element that allows carrying out such
protocol consists of a magnetic particle brake whose control action is strongly influenced by the
dynamics of the system when in contact with the end user, specifically the patient's legs in the
stretch from the knee to the ankle. The results of these tests are valuable for health professionals
seeking to measure their patient’s progress during the rehabilitation process and determine when
it is safe and appropriate to advance in their treatment.
