Clinical Outcomes: VAS Arm24 monthsImprovement of clinical outcomes (VAS Arm) for all enrolled patients. Improvement is a reduction of scores for all clinical outcomes. Results will be shown as change from baseline to 24 month follow-up. The visual analogue scale (VAS) is a commonly used outcome measure for research studies. It is presented as a 100-mm horizontal line on which the patient's pain intensity is represented by a point between the extremes of 0/no pain at all and 100/worst pain imaginable. The study in this scale is used for the worst arm pain. A lower score represents a better score.
Clinical Outcomes: VAS Neck24 monthsImprovement of clinical outcomes (VAS Neck) for all enrolled patients. Improvement is a reduction of scores for all clinical outcomes. Results will be shown as change from baseline to 24 month follow-up. The visual analogue scale (VAS) is a commonly used outcome measure for research studies. It is presented as a 100-mm horizontal line on which the patient's pain intensity is represented by a point between the extremes of 0/no pain at all and 100/worst pain imaginable. The study in this scale is used for neck pain. A lower score represents a better score.
Clinical Outcomes: NDI24 monthsImprovement of clinical outcomes (NDI) for all enrolled patients. Improvement is a reduction of scores for all clinical outcomes. Results will be shown as change from baseline to 24 month follow-up. The NDI is an index derived from the Neck Disability Index Pain Questionnaire used by surgeons, clinicians and researchers to quantify disability for neck pain. Scores are from 0-100 and a lower score represents a better score.
