Ulnar Neuropathy, Neuromuscular Disorders
||Oscar Soto, MD, PhD
The purpose of this study is to understand why some patients with nerve entrapment at the elbow do better than others. This study is investigational because it attempts to address the problem comprehensively, using different techniques, something that is not usually done for routine diagnostic purposes.
- Patients with ulnar neuropathy of the elbow
- Known active polyneuropathy(PN)
- Co-morbid disorders frequents associated with PN (i.e. diabetes, chronic renal failure, chemotherapy in the past 6 months)
- Coincidental neuropathy at the arm or wrist
All the procedures will be performed in a single day, and the process will take about one hour to complete.
- Complete a set of questions regarding your symptoms, even if you do not have any.
- Record the strength of your hand muscles, both by hand and with the use of a force recording device.
- Perform a tests called nerve conduction studies. This test involves electrical stimulation of different nerves in one or both arms. There is some discomfort in regards to the electrical stimulation, but most people tolerate it without any problems.
- Ultrasound of the nerves in the upper extremity, a painless procedure which allows us to determine the nerve size.
- We would like to contact you via telephone or email one year later to get information in regards to your potential symptoms or absence of any symptoms.
All the procedures described above are standard nerve care for peripheral nerve problems, and none of them is an experimental procedure.
