The tonic ambulatory foot response. A clinical and electromyographic study.
Three cases with "pyramidal" symptoms in which standing and/or walking evoked a tonic flexion of the toes and sole of the affected foot, have been studied from the clinical and electrophysiological standpoint. The phenomenon, for which the definition of tonic ambulatory foot respone (TAFR) is proposed, appeared to be triggered by cutaneous stimuli travelling along fibres lying in the range of nociceptive afferents, and to depend on a background of complex sensorimotor patterns of standing posture and/or stepping movements against resistance. The relationship of TAFR to other flexor foot responses described in the literature is discussed.
