Brief summary
The objective of this study is to evaluate efficacy of varied medical and procedural therapies used to treat pain after surgical amputation of a limb. The primary outcome will be assessment of pain severity at rest and with movement as measured by pain scores on Numerical Rating Scale (NRS) 0 to 10, where 0 is not pain and 10 is the worst pain possible, taken on post-operative day 1, day 7, 30 days, 90 days, 6 months, and 1 year (+/- 3 days at each time point).
Detailed description
The objective of this study is to evaluate efficacy of varied medical and procedural therapies used to treat pain for surgical amputation of a limb. At present there are number of different type of therapies are performed in the patients who is going through an amputation of any limb for management of their pain adequately such as peripheral nerve block, epidurals, peripheral nerve stimulators etc. However, the effects of these different procedures performed at different time intervals have not been evaluated for their effects on phantom pain and somatic pain long term after the procedures in these group of patients. We will be collecting the following data from these patients to see if there is any particular intervention done at particular time of the procedure ( before the amputation vs. after the amputation) affect the long term outcome of these patients such as development of Phantom pain, or chronic pain The primary outcome will be assessment of pain severity at rest and with movement as measured by pain scores on Numerical Rating Scale (NRS) 0 to 10, where 0 is not pain and 10 is the worst pain possible, taken on postoperative day 1, day 7, 30 days, 90 days, 6 months, and 1 year (+/- 3 days at each time point). The secondary outcomes will be 1) phantom limb pain severity as rated on NRS 2) Residual limb (stump) pain as rated on NRS 3) phantom limb sensations 4) Pain Disability Index scores 5) Morphine milligram equivalents. These secondary outcomes will be assessed at the same intervals as the primary outcome. This study will help us to find out if there is any utility of any of these procedures performed at particular time of the procedure helps them more than the others for development of somatic or phantom pain.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Pain Severity at rest and movement | 1 year | The primary outcome will be assessment of pain severity at rest and with movement as measured by pain scores on Numerical Rating Scale (NRS) 0 to 10 taken on post-operative day 1, day 7, 30 days, 90 days, 6 months, and 1 year (+/- 3 days at each time point). 0 means no pain and 10 means the worst pain ever. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The amount of pain medication used. | 1 year | The sixth outcomes will be the amount of Morphine milligram equivalents. The amount taken on post-operative day 1, Day 1 to day 7, day 8 to 30 days, 31 days to 90 days, 91 days to 6 months, and from 6 months to 1 year (+/- 3 days at each time point). |
| Using NRS to rate phantom limb pain change in severity | 1 year | The secondary outcomes will be phantom limb pain severity as rated on NRS. 0 to 10 taken on post-operative day 1, day 7, 30 days, 90 days, 6 months, and 1 year (+/- 3 days at each time point). 0 means no pain and 10 means the worst pain ever. |
| Using NRS to rate severity of change in pain | 1 year | The third outcomes will be Residual limb (stump) pain as rated on NRS. 0 to 10 taken on post-operative day 1, day 7, 30 days, 90 days, 6 months, and 1 year (+/- 3 days at each time point). 0 means no pain and 10 means the worst pain ever. |
| Using NRS to rate of change in severity of Phantom limb sensations. | 1 year | The fourth outcomes will be phantom limb sensations. 0 to 10 taken on post-operative day 1, day 7, 30 days, 90 days, 6 months, and 1 year (+/- 3 days at each time point). 0 means no sensation and 10 means the worst feeling ever. |
| Using NRS to rate Pain Disabiliy | 1 year | The Fifth outcomes will be Pain Disability Index scores. 0 to 10 taken on post-operative day 1, day 7, 30 days, 90 days, 6 months, and 1 year (+/- 3 days at each time point). of 0 means no disability at all, and a score of 10 signifies that all of the activities in which you would normally be involved have been totally disrupted or prevented by your pain. |
