Change from Baseline in Pain (VAS/Visual Analog Score)

A VAS score, also known as a Visual Analog Scale score, is a common method used in healthcare and research to measure subjective or self-reported sensations or experiences, such as pain, anxiety, mood, or other subjective states. It typically consists of a horizontal or vertical line, usually 10 centimeters in length, with anchor points at either end. One end is labeled with the most negative or extreme aspect of the sensation or experience being measured, and the other end is labeled with the most positive or least extreme aspect.

Change from Baseline in function (JOA/Japanese Orthopaedic Association Score) score

The JOA score is often calculated based on a specific set of criteria and is used to help guide treatment decisions and monitor a patient's progress. It provides a standardized way to assess and communicate the clinical status of individuals with cervical myelopathy. The score may range from 0 (severe impairment) to 17 (normal function), with lower scores indicating greater disability.

Change from Baseline in function (NDI/Neck Disability Index score) score

The NDI questionnaire typically consists of ten questions or items, and individuals are asked to rate their level of disability or limitation in various aspects of daily life due to neck pain. The questions cover a range of activities, including personal care, work, sleep, and recreational activities. Each question is scored on a scale from 0 to 5, with 0 indicating no disability and 5 indicating severe disability. The individual's responses to these questions are then totaled to calculate the NDI score, usually expressed as a percentage.
