On Gravity Correction for Training and Rehabilitation Lower Limbs Machine

During a training or rehabilitation session on an isokinetic machine for lower limbs also known as dynamometer, it's necessary to know the real muscular effort by compensating the gravity or undesirable dynamic effects. Thus, the aim of this work is to give a theoretical study and experimentally evaluation of two gravity correction methods. We'll then discuss the advantages and drawbacks of each method and give new trends to follow in this domain
