Carpal Tunnel Syndrome (CTS) is a common form of median nerve compression that typically results in tingling, numbness and pain in the hand and fingers. Multiple treatments ranging from conservative interventions of orthotic fabrication and exercises to surgery can be tried to alleviate these symptoms.
The Journal of Hand Therapy recently featured a randomized clinical trial that tested the effectiveness of several conservative treatments for CTS. The Turkish researchers evaluated the following treatments for patients diagnosed with mild to moderate carpal tunnel syndrome:
- Wrist orthoses
Conservative treatments put to the test
The study was conducted on a group of 110 female patients. These patients were evaluated using nerve conduction studies and ultrasonography. Clinical testing also included:
- Hand grip and finger pinch measures
- The Visual Analogue Scale (VAS) for pain
- The Boston Carpal Tunnel Syndrome Questionnaire for symptoms and function.
The patients were randomly assigned to either treatment with:
- A volar based wrist orthosis
- Kinesiotaping and a wrist orthosis
- Paraffin treatments and a wrist orthosis
See full article for details of these techniques and how they were applied.
Evaluations were performed at 3 weeks, 3 months and (for some patients) at a 6-month follow-up.
Results of the study showed improvements in clinical, ultrasonographical and electrophysiological areas in all three treatment groups. The improvements were seen at the 3 week and 3 month evaluations and even lasted through to 6 months.
The group that was treated with orthotic wear and kinesiotaping appears to have statistically better results in terms of pain reduction and grip strength, especially for those patients with mild carpal tunnel syndrome.
All treatment groups showed evidence of clinical improvements as well as improved motor and sensory latency scores on electrodiagnostic testing. The researchers also noted improved results in ultrasonographic data, i.e. a decrease in the median nerve cross-sectional area.
The role of orthotic fabrication
The use of an orthosis continues to be an effective conservative treatment for patients with mild CTS and can also be helpful at reducing symptoms for those with moderate CTS. It may be useful to look into combining the orthosis with additional treatment techniques such as kinesiotaping (once the techniques of application have been mastered).
Orthotic fabrication ideas for carpal tunnel syndrome
Volar based orthosis
Learn how to fabricate a comfortable and effective volar wrist orthosis for the treatment of carpal tunnel syndrome. Discover our orthotic fabrication tips or watch our instructional video for a visual guide of the Volar Wrist Cock-Up Orthosis:
A volar wrist orthosis can be fabricated from many different materials, depending on the therapist’s and the patient’s preferences.
For most adults, 3 mm (1/8″) is the appropriate thickness for this design. However, for some individuals, 2 mm (1/12″) might offer enough support. If that’s the case, you can choose Orfit Colors NS.
Try Orfilight for a lightweight orthosis that will not add extra weight to the patient’s extremity.
Dorsal based orthosis
A dorsal based design can also be a suitable option for carpal tunnel syndrome and is ideal for patients who want to leave their palms free.
