BOTOX® (Onabotulinumtoxin A) Injection(s) as a Treatment for Carpal Tunnel Syndrome

This is a pilot study, to assist with determining appropriate BOTOX® (onabotulinumtoxin A) dosing and injection locations in patients suffering from CTS. Outcome measures will be obtained at follow-up at 6, 12, and 18 weeks post BOTOX® (onabotulinumtoxin A) injection and post saline injection using the same scales and instruments at baseline, namely Levine scale, JAMAR pinch dynamometer, EDX/NCS and NMUS. These measurements will be used to identify the effectiveness of BOTOX® (onabotulinumtoxin A) in decreasing thenar muscle strength, appropriate BOTOX® (onabotulinumtoxin A) injection dosing, and ability to decrease the inflammation, median nerve dysfunction, edema, symptoms of pain, numbness, and tingling often with associated with CTS.
