Trial Outcomes & Findings for Investigating Botulinum Toxin A to Treat Acute Neck/Upper Shoulder Pain Following a New Spinal Cord Injury. (NCT NCT00320281)

NCT ID: NCT00320281

Last Updated: 2020-10-14

Results Overview

The Numerical Rating Scale (NRS) is a numerical scale from 0-10 used to rate pain. Participants were asked to assess the worst pain experienced in the past 5 days and rate it on a numerical scale from 0-10, with 10 being the "worst possible pain" they have experienced and 0 being "no pain."

Outcome measures

Outcome measures
Measure
Group 1-Botox A Group
n=10 Participants
Those randomized to this treatment group received injections based on treatment plan designed by PI and study physical therapist. Botulism toxin A was diluted in 25 cc of saline for the injections. Multiple injections may have occured during a single clinic visit based on pain/stiffness upon assesment by the study treatment team.
Group 2-saline Group
n=9 Participants
Those randomized to this treatment group received injections based on treatment plan devised by study PI and study physical therapist. 25 cc of saline were used for these injections. Multiple injections may have occured during a single clinic visit based on pain/stiffness upon assesment by the study treatment team.

SECONDARY outcome

Timeframe: 6 months post-injection

Interference in daily activities was measured with the Brief Pain Inventory (BPI) Interference Score. Participants rated the extent to which pain interfered with their participation in six general activities during the past week, using a scale of 0 (does not interfere) to 10 (completely interferes). Note that for the purposes of this study, the question regarding walking was removed from the original scale which has seven items). Mean score across the 6 items was calculated (range could be 0 - 10) with higher score indicating more pain interference.
