What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Difference in mean Numerical Rating Scale (NRS) for pain scores
Time Frame: 3 months
|
Difference in the mean pain scores before and after procedure.
Scale from 0 to 10, where higher scores mean worse outcome
|
3 months
|
Proportion of patients with positive analgesic response
Time Frame: 3 months
|
Proportion of patients with positive analgesic response (≥50% reduction in the NRS score for neck pain compared to baseline)
|
3 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Difference in the mean Numerical Rating Scale (NRS) for pain scores
Time Frame: at 6 and 12 months
|
Difference in mean NRS for pain scores at 6 and 12 months after the RFA procedure.
Scale from 0 to 10, where higher scores mean worse outcome
|
at 6 and 12 months
|
Proportion of patients with positive analgesic response
Time Frame: at 6 and 12 months
|
Proportion of patients with positive analgesic response (≥50% reduction in the NRS score for neck pain compared to baseline) at 6 & 12 months
|
at 6 and 12 months
|
Proportion of patients with reduction in the Neck Disability Index (NDI) score
Time Frame: at 3, 6, and 12 months
|
Proportion of patients with ≥10% reduction in the NDI score at 3, 6, and 12 months.
Scale from 0 to 50, where higher scores mean worse outcome
|
at 3, 6, and 12 months
|
Proportion of participants reporting improvement in the Patient Global Impression of Change (PGIC) scale
Time Frame: at 3, 6, and 12 months
|
PGIC score is a 7 point scale depicting a patient's subjective rating of overall improvement over time, as proportion of participants reporting improvement in the PGIC scale at 3, 6, and 12 months
|
at 3, 6, and 12 months
|
Difference in mean Pittsburgh Sleep Quality Index (PSQI) scores for sleep quality
Time Frame: at 3, 6, and 12 months
|
Difference in mean PSQI scores scores at 3, 6, and 12 months.
It has a range of 0-21; higher scores indicate worse sleep quality.
|
at 3, 6, and 12 months
|
Difference in mean European Quality of Life (EQ-5D-5L score), a self-assessed, health related, quality of life questionnaire. It ranges from 5 to 25, where higher scores indicate worse outcome.
Time Frame: at 3, 6, and 12 months
|
Difference in mean EQ-5D-5L scores at 3, 6, and 12 months
|
at 3, 6, and 12 months
