Fig 1 The strength of velocity-dependent activation of the rectus femoris muscle (RECflex INC) depends on the amplitude of tendon jerks in patients with spasticity (○), but not in patients with dystonia (•). The ranges of the normal values marked with the shaded area. Archives of Physical Medicine and Rehabilitation 2004 85, 875-880DOI: (10.1016/j.apmr.2003.06.032)
Fig 2 Patients with dystonia (•) walked slower (v) than patients with spasticity (○), as a result of decreased strength (MVCext). NOTE. MVCext=2.58+6.16v; r=.54. Archives of Physical Medicine and Rehabilitation 2004 85, 875-880DOI: (10.1016/j.apmr.2003.06.032)
