Involvement of both sensory and motor fibers means that the patient’s sensory and motor fibers are both damaged to some degree, which may be manifested by decreased or absent sensation, abnormal behavior of the limbs, and so on.
Sensory fibers, also called receptor neurons, transmit nerve stimuli from receptors or sensory organs to the central nervous system. When sensory fibers are damaged, the conduction of impulses is blocked, resulting in diminished sensation in the patient. For example, the superficial sensations of the skin (pain, warmth, etc.) and the deep sensations of the muscles, tendons, and joints (kinaesthesia, positional sensation, etc.) are diminished or lost to some extent.
Motor fibers are generally efferent nerves that primarily transmit excitation from the central nervous system to various organs or peripheral parts. When the efferent nerves are damaged, the nerve function of the central system to innervate the body will be weakened, and the patient may experience symptoms such as uncoordinated limbs, unsteady walking, and involuntary trembling of the limbs.
Patients are advised to seek timely medical treatment and undergo standardized treatment under the guidance of professional doctors.
