nps_pain_scale: Neuropathic Pain Scale (NPS)

Description

Calculates the Neuropathic Pain Scale (NPS) score. Unlike diagnostic tools (e.g., DN4), the NPS is designed to assess the distinct qualities of neuropathic pain (e.g., sharp, hot, dull) and monitor changes in these specific symptoms over time or in response to treatment.

Usage

nps_pain_scale(intensity, sharp, hot, dull, cold, sensitive, itchy,
               unpleasant, deep, surface)

Value

A list containing:

NPS_Total_Score

The sum of all 10 item scores (Range 0-100).

Interpretation

Guidance on using the score for monitoring treatment response.

Domain_Scores

A breakdown of the individual pain quality scores.
