---|---|---|---|---|
Primary | Change in neuropathic pain | Measured using the patient reported Neuropathic Pain Symptom Inventory (NPSI) which uses a scale of 0 = "have not felt such pain" and 10 = "feel it the worst" for a total score with a higher score indicates greater pain. | Baseline, 1 month, 3 months, 6 months, 12 months, 18 months, 24 months, and 36 months | |
Primary | Change in multidimensional pain inventory | Measured using the West Haven-Yale Multidimensional pain inventory self-reported questionnaire to assess the impact of pain on daily living | Baseline, 1 month, 3 months, 6 months, 12 months, 18 months, 24 months, and 36 months | |
Primary | Change in Douleur Neuropathique 4 (DN4) Questionnaire | Change in DN4 questionnaire to estimate the probability of neuropathic pain with seven questions asking patients about quality of pain and three questions for physical examination of pain. Questions are yes = 1 or no = 0 to obtain a patient's total score out of 10, higher scores indicate more probability of pain. | baseline, 1 month, 3 months, 6 months, 12 months, 18 months, 24 months, and 36 months | |
Primary | Change in pain intensity | Measured using the PROMIS-CAT pain intensity scale | Baseline, 1 month, 3 months, 6 months, 12 months, 18 months, 24 months, and 36 months | |
Primary | Change in pain interference | Measured using the PROMIS-CAT pain interference scale | Baseline, 1 month, 3 months, 6 months, 12 months, 18 months, 24 months, and 36 months | |
Secondary | Change Disabilities of the Arm, Shoulder and Hand (DASH) disability/symptom score | Measured using the self-reported DASH 30-item questionnaire to assess the ability to perform activities. Total score on a scale of 0 indicating no disability to 100 indicating most serve disability | Baseline, 1 month, 3 months, 6 months, 12 months, 18 months, 24 months, and 36 months | |
Secondary | Assessment of the effectiveness of high frequency spinal cord stimulation in the above population in the improvement of quality of life as measured by validated patient-completed questionnaires. | Measured using the EQ-5D. | baseline, 1 month, 3 months, 6 months, 12 months, 18 months, 24 months, and 36 months | |
Secondary | Change in mood | Measured using the Center for Epidemiologic Depression Studies - Depression Scale. A 20-item self-reported questionnaire using a scale of 0 (rarely or none of the time) and 3 (most or all of the time) for a total score with high scores indicating the presence of more | Baseline, 1 month, 3 months, 6 months, 12 months, 18 months, 24 months, and 36 months | |
Secondary | Change in pain experience | Change in self-reported 13-item Pain Catastrophizing scale of 0 (not at all) and 4 (all the time) for a total score with higher scores indicating higher levels of pain anxiety | Baseline, 1 month, 3 months, 6 months, 12 months, 18 months, 24 months, and 36 months | |
Secondary | Change in pain anxiety | Measured using the self-reported Pain Anxiety Symptom Scale Short Form 20 to rate frequency of symptoms on a scale of 0 (never) to 5 (always) for a total score with higher score indicating high levels of pain-related anxiety | Baseline, 1 month, 3 months, 6 months, 12 months, 18 months, 24 months, and 36 months | |
Secondary | Assessment of the effect of high frequency spinal cord stimulation in the above population on sensory function in the affected limb. | Measured using Quantitative Sensory Testing | Baseline, 1 month, 3 months, 6 months, 12 months, 18 months, 24 months, and 36 months |
