Modulation of cutaneous reflexes is important in the neural control of walking, yet knowledge about underlying neural pathways is still incomplete. Recent studies have suggested that the cerebellum is involved. Here, we evaluated the possible roles of the cerebellum in cutaneous reflex modulation and in attenuation of self-induced reflexes. First it was checked whether leg muscle activity during walking was similar both in patients with focal cerebellar lesions and in healthy controls. We then recorded cutaneous reflex activity in leg muscles during walking. Additionally, we compared reflexes after standard (computer-triggered) stimuli with reflexes after self-induced stimuli for both groups. Biceps femoris and gastrocnemius medialis muscle activity was increased in the patient group compared to the controls, suggesting a co-activation strategy to reduce instability of gait. Cutaneous reflex modulation was similar between healthy controls and cerebellar patients, but the latter appeared less able to attenuate reflexes to self-induced stimuli. This suggests that the cerebellum is not primarily involved in cutaneous reflex modulation but that it could act in attenuation of self-induced reflex responses. The latter role in locomotion would be consistent with the common view that the cerebellum predicts sensory consequences of movement.
