Nerve conduction studies in the upper limb in the malwa region-normative data

Area of Science:

• Clinical Neurophysiology
• Neurology
• Medical Research

Background:

• Establishing normative electrophysiological data is essential for diagnosing peripheral nerve disorders.
• Regional variations in nerve conduction parameters necessitate localized reference values.

Purpose of the Study:

• To determine the normal electrophysiological values for the median and ulnar nerves in healthy adults residing in the Malwa region of Punjab, India.
• To provide a regional normative database for clinical electrodiagnostic assessments.

Main Methods:

• Prospective nerve conduction studies were conducted on 100 healthy adults (20-60 years old).
• Standardized techniques were employed for motor and sensory nerve conduction studies of the upper limbs.
• Data analysis focused on distal latency, amplitude, and conduction velocity for median and ulnar nerves.

Main Results:

• Normal electrophysiological values for median and ulnar motor and sensory nerves were established.
• Motor nerve conduction parameters showed favorable correlation with existing literature.
• Sensory nerve action potential amplitudes were higher in this study compared to some previous reports.
• Gender had a statistically significant effect on sensory nerve action potential amplitudes for both median and ulnar nerves.

Conclusions:

• Normative conduction parameters for commonly tested upper limb nerves were successfully established for the Malwa region.
• The established data serve as a valuable reference for electrophysiological laboratories in the region.
• The study highlights potential differences in sensory nerve action potential amplitudes, emphasizing the importance of regional normative data.
