Trial Outcomes & Findings for Comparison of Dorsal Column Stimulation to Dorsal Root Ganglion Stimulation for Complex Regional Pain Syndrome (NCT NCT03794024)

NCT ID: NCT03794024

Last Updated: 2023-02-27

Results Overview

To compare the outcomes of dorsal column stimulation with Dorsal Root Ganglion stimulation in patients with Complex Regional Pain Syndrome that persist despite a course of conservative management including physical therapy and analgesic pharmacotherapy using an 11-point \[0-10\] Numerical Rating Scale (NRS) for Pain Intensity at 6 months. A score of zero indicates no pain, and 10 indicates the worst possible pain imaginable.

Measure
Dorsal Column Stimulation
Subjects with Complex Regional Pain Syndrome receiving implant with the Nuvectra Algovita Dorsal Column Spinal Cord Stimulator The Nuvectra Algovita Dorsal Column Spinal Cord Stimulator: The Nuvectra Algovita Dorsal Column Spinal Cord Stimulator is indicated as an aid in the management of chronic intractable pain of the trunk and/or limbs, including unilateral or bilateral pain associated with failed back surgery syndrome, intractable low back pain and leg pain.
Dorsal Root Ganglion Stimulation
Subjects with Complex Regional Pain Syndrome receiving implant with the Axium Neurostimulator System The Axium Neurostimulator System: The Axium Neurostimulator System is indicated for spinal column stimulation via epidural and intra-spinal lead access to the dorsal root ganglion as an aid in the management of moderate to severe chronic intractable pain of the lower limbs in adult patients with Complex Regional Pain Syndrome Types I and II

PRIMARY outcome

Timeframe: 6 Months

Population: No patients achieved the 6 month endpoint

To compare the outcomes of dorsal column stimulation with Dorsal Root Ganglion stimulation in patients with Complex Regional Pain Syndrome that persist despite a course of conservative management including physical therapy and analgesic pharmacotherapy using an 11-point \[0-10\] Numerical Rating Scale (NRS) for Pain Intensity at 6 months. A score of zero indicates no pain, and 10 indicates the worst possible pain imaginable.

SECONDARY outcome

Timeframe: 6 Month

Population: Data were not collected

To compare the outcomes of dorsal column stimulation with Dorsal Root Ganglion stimulation in patients with Complex Regional Pain Syndrome that persist despite a course of conservative management including physical therapy and analgesic pharmacotherapy in function based on Oswestry Disability Index (ODI) for functional impairment. A score of 0 on the 101-point \[0-100\] Oswestry Disability Index indicates no disability while 100 indicates bed-bound.

OTHER_PRE_SPECIFIED outcome

Timeframe: 6 Months

Population: Data were not collected

Change in Quality of Life as measured by the European Quality of Life 5 Dimension (EQ-5D) Scale. The EQ-5D-5L is composed of - the EQ-5D-5L descriptive system and the EQ Visual Analogue scale (EQ VAS). The descriptive system comprises 5 dimensions (mobility, self care, usual activities, pain/discomfort, anxiety/depression). Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. Each level corresponds to 1-digit number expressing the level selected for that dimension.

OTHER_PRE_SPECIFIED outcome

Timeframe: 6 Months

Population: Data were not collected

Change in Health Status measured by Short Form-36 (SF-36). This form measures patient's overall health. Scores range from 0 - 100 with lower scores indicating more disability while higher scores indicate less disability.

OTHER_PRE_SPECIFIED outcome

Timeframe: 6 Months

Population: Data were not collected

The opioid morphine equivalent conversion factor is used to standardized opioid usage having as a reference morphine as the main indicator for analgesic potency. Oral morphine equivalents are based on the idea that different doses of different opioids may give a similar analgesic effect. Where the doses of two different opioids are considered to give a comparable analgesic effect, they are deemed to be equianalgesic doses.

OTHER_PRE_SPECIFIED outcome

Timeframe: 6 Months

Population: Data were not collected

There will be 3 separate questions on the form. Subjects will be asked to rate their satisfaction with the pain relief, satisfaction with the therapy in general and their likelihood undergoing the therapy again for a similar outcome as a percentage from 0-100% with 0% indicating no satisfaction/likelihood and 100% indicating completely satisfied and 100% likelihood of undergoing the therapy again for a similar outcome.

OTHER_PRE_SPECIFIED outcome

Timeframe: 6 Months

Population: Data were not collected

Patients will be asked to rate their overall change in quality of health on a scale of 1 to 7 with 1 being no change in overall health and 7 being a great deal better in comparison to before implant. Another scale will on the same form ranging from 0-10 with 0 being much better, 5 being no change and 10 being much worse.
