What does the presence of temporal dispersion indicate?

• A. Consistent conduction speed
• B. Improved nerve function
• C. Inconsistent conduction delays
• D. Increased sensory response

Answer: (C)

Temporal dispersion refers to the phenomenon where the electrical signals traveling along a nerve are not synchronously arriving at the recording electrode. This can be observed in nerve conduction studies as variations in the timing of the responses from multiple fibers within a nerve. When temporal dispersion is present, it indicates that there are inconsistent conduction delays among the nerve fibers. This inconsistency often results from factors such as demyelination or other types of nerve pathology that affect the uniform propagation of action potentials. Therefore, the presence of temporal dispersion is a strong indicator of a problem within the nerve conduction process, reflecting a lack of synchronized conduction that can significantly affect overall nerve function. In this context, options that suggest improved function or consistent conduction speed do not align with the implications of temporal dispersion, as it highlights dysfunction rather than efficiency in nerve impulse transmission.
