This study establishes normative nerve conduction studies (NCS) data for the Pakistani population, revealing ethnic variations compared to Western data. Findings highlight age and gender influences on nerve conduction parameters in South Asians.
Area of Science:
- Neurophysiology
- Clinical Electrophysiology
- South Asian Health
Background:
- Global neurophysiology departments often lack ethnic considerations in normative data.
- Establishing population-specific reference values is crucial for accurate diagnosis.
- Ethnic variations can significantly impact nerve conduction study results.
Purpose of the Study:
- To establish normative nerve conduction studies (NCS) data for Pakistani adults.
- To investigate the influence of age and gender on NCS parameters in this population.
- To compare Pakistani NCS data with existing Western and other ethnic datasets.
Main Methods:
- Standardized nerve conduction studies (NCS) were performed on 100 healthy Pakistani adults.
- Participants were categorized into age groups, and gender differences were analyzed.
- Data analysis focused on median, ulnar, and sural nerves, including motor and sensory parameters.
Main Results:
- Age significantly affected median distal motor latency (DML), F-wave latency, and sensory amplitudes.
- Females exhibited significantly shorter DMLs and F-wave latencies compared to males.
- Pakistani NCS results showed higher amplitudes and faster velocities than American and Malaysian data, aligning with South Asian studies.
Conclusions:
- Recommended normative NCS parameters for the Pakistani population are provided.
- Standardized techniques are essential for high-quality NCS testing and interpretation.
- Acknowledging ethnic differences in NCS is vital for accurate neurophysiological assessments.

Testing a Claim about Mean: Known Population SD
Estimating a population mean requires the samples to be distributed normally. The data should be collected from the randomly selected samples having no sampling bias. The sample size needed to be higher than 30, and most importantly, the population standard deviation should be already known.
In most realistic situations, the population standard deviation is often unknown, but in rare circumstances, when it...
