LLRs and the silent period are EMG phenomena that reflect the complex interplay of spinal, brain stem, and cortical influences in motor control. These techniques have been applied to the study of disorders of motor control such as Parkinson’s disease, Huntington’s disease, and dystonia. Abnormalities of these reflexes may help to detect lesions of the central nervous system.
