Recent studies involving patients with CNS lesions have clearly demonstrated that agonist paresis rather than antagonist spasticity is the primary factor limiting torque production. The presence of spasticity can, nonetheless, be important because of its effect on the quality of movement and because of the propensity of spastic muscles toward contracture. Therefore, methods for more precisely d...

In this paper, the lord magnetic field of MRF and its circuit design are mainly expounded, according to the loading ways of magnetic field and the magnetic circuit design plans of magneto-rheological fluid devices at present, the general form and characteristics are summarized. In addition, a kind of magneto-rheological fluid dynamometer is proposed in this paper, in terms of its magnetic circu...
