There is an ongoing trial of a new medical device for carpal tunnel sufferers.

It's at beth israel hospital in nyc. The device is called carpal-ease.

The infortaion is as folows:

painful conditions of the wrist
irb #092-05 a study of the effectiveness and safety of the carpal-ease unit for the treatment of wrist pain

principal investigators: peter homel, phd
contact: ella dvorkin, msw, csw, (212) 844-1483
status: open for enrollment
design: this is a research study of an experimental device called carpal-ease as a therapy in the management of painful conditions of the wrist. The carpal-ease unit is investigational, which means that it has not received marketing approval from the u.S. Food and drug administration (fda).
This research study is being done to see if the carpal-ease unit is an effective treatment for wrist pain due to carpal tunnel syndrome, wrist arthritis or wrist repetitive stress syndrome. The study will compare the active treatment, when the carpal-ease unit is turned on, to a placebo (when the unit is turned off).

The carpal-ease unit is a newly designed system that uses a low voltage electrical energy to encourage the flow of excess fluid (swelling) inside the carpal tunnel to flow outward. The result relieves pressure on the median nerve, which in turn leads to reduction in pain and greater ease of movement.

The study will take place over four weeks.
