A value indicative of an amplitude of the reflexive contraction is electronically recorded. ## Claims ### Claim 1 A method of training an individual comprising the steps of: receiving data indicative of a training suitability state of an individual upon a support platform, where the support platform is tiltable in response to contraction of a muscle in the individual's body redistributing the individual's body weight upon the support platform; commanding electrical stimulation of a spinal reflex pathway innervating the muscle in the individual, responsive to the data, and such that the muscle reflexively contracts to tilt the support platform; perturbing a balance of the individual while standing, via the electrical stimulation; and electronically recording a value indicative of an amplitude of the reflexive contraction. ### Claim 2 (depends on 1) The method of claim 1 wherein the muscle includes the soleus muscle, and the step of commanding includes commanding electrical stimulation of a sensory nerve through the individual's skin on the back of the knee. ### Claim 3 (depends on 2) The method of claim 2 wherein the step of receiving further includes receiving data indicative of electrical activity of the muscle, and data indicative of a tilt angle of the support platform about a horizontal axis. ### Claim 4 A method of training an individual comprising the steps of: receiving data indicative of a training suitability state of an individual upon a support platform, data indicative of electrical activity of the muscle, and data indicative of a tilt angle of the support platform about a horizontal axis, wherein the support platform bears substantially the entire body weight of the individual while standing, where the support platform is tiltable in response to contraction of a muscle in the individual's body redistributing the individual's body weight upon the support platform; commanding electrical stimulation of a spinal reflex pathway innervating the muscle in the individual, responsive to the data, and such that the muscle reflexively contracts to tilt the support platform, wherein the muscle includes the soleus muscle, and the step of commanding includes commanding electrical stimulation of a sensory nerve through the individual's skin on the back of the knee; perturbing a balance of the individual while standing, via the electrical stimulation; and electronically recording a value indicative of an amplitude of the reflexive contraction. ### Claim 5 (depends on 4) The method of claim 4 wherein the step of electronically recording further includes populating a stored history of reflexive contraction amplitudes in a plurality of repetitions of the receiving and commanding steps. ### Claim 6 (depends on 5) The method of claim 5 further comprising a step of comparing the value with a second value indicative of an amplitude of a reflexive contraction in at least one prior repetition of the receiving and commanding steps, and outputting a display signal to a graphical display, responsive to the comparison. ### Claim 7 (depends on 4) The method of claim 4 wherein the step of receiving further includes receiving data indicative of a joint angle in an ankle joint of the individual from a joint angle sensor coupled to the individual. ### Claim 8 (depends on 4) The method of claim 4 wherein the step of receiving further includes receiving data indicating the tilt angle is within a suitable range of tilt angles. ### Claim 9 (depends on 4) The method of claim 4 wherein the support platform includes an adjustable stability varying mechanism including a plurality of configurations each corresponding to a different stability state, and further comprising a step of receiving data from a sensing mechanism coupled to the support platform indicative of a present configuration of the adjustable stability varying mechanism. ### Claim 10 (depends on 3) The method of claim 3 wherein the step of receiving further includes receiving data indicative of a joint angle in an ankle joint of the individual from a joint angle sensor coupled to the individual. ### Claim 11 (depends on 3) The method of claim 3 wherein the step of receiving further includes receiving data indicating the tilt angle is within a suitable range of tilt angles. ### Claim 12 (depends on 1) The method of claim 1 wherein the support platform includes an adjustable stability varying mechanism including a plurality of configurations each corresponding to a different stability state, and further comprising a step of receiving data from a sensing mechanism coupled to the support platform indicative of a present configuration of the adjustable stability varying mechanism. ### Claim 13 A system for training an individual comprising: a support platform configured to support an individual for training, and tiltable in response to contraction of a muscle in the individual's body redistributing the individual's body weight upon the support platform; a plurality of sensing mechanisms, wherein the plurality of sensing mechanisms includes a first sensor configured to monitor a tilt parameter of the support platform, a second sensor configured to monitor a muscle activity parameter of the muscle, and a third sensor configured to monitor an ankle joint angle parameter in the individual;
