Significance of Visual analogue scale
The Visual Analogue Scale (VAS) is a widely used measurement tool for assessing pain intensity. It consists of a 10 cm line on which patients mark their level of pain, ranging from 'no pain' to 'worst pain imaginable'. This method provides a reliable and valid way to quantify subjective pain experiences, enabling healthcare providers to evaluate treatment efficacy and track pain relief over time. VAS helps in objectively measuring the severity of pain and facilitates better assessment of patients' symptoms.
