Cutaneous reflex in human locomotion
Cutaneous, or skin reflexes, are activated by skin receptors and play a valuable role in locomotion, providing quick responses to unexpected environmental challenges. They have been shown to be important in responses to obstacles or stumbling, in preparing for visually challenging terrain, and for assistance in making adjustments when instability is introduced. In addition to the role in normal locomotion, cutaneous reflexes are being studied for their potential in enhancing rehabilitation therapy (physiatry) for people with gait abnormalities.
== Background of reflex pathway ==
Reflexes are a vital part of our everyday activities. We have all experienced how fast and automatic these responses to environmental interactions can be. They can protect us from potentially dangerous situations such as touching a hot stove or stepping on a tack. There are also reflex pathways involved in more dynamic activities such as walking and running, helping to ensure a smooth gait and allowing us to respond quickly to obstacles or unexpected perturbations or disturbances.
The reflex pathway (reflex arc) is a sequence of neurons connecting the sensory input (afferent neuron) to the motor output (efferent neuron), resulting in a behavioral response. The general pathway of a spinal reflex is one which involves neurons contained within the spinal cord. However, the brain may also provide additional (supraspinal) contributions, which can modulate the responsiveness of the reflex to the sensory input.
