Kaplan, B. M., Akyuz, G., Kokar, S., & Yagci, I. (2018). Comparison of the effectiveness of orthotic intervention, kinesiotaping, and paraffin treatments in patients with carpal tunnel syndrome: A single-blind and randomized controlled study. Journal of Hand Therapy, 32, 297-304.
The authors completed a randomized control trial with three groups to test the effectiveness of kinesiotape and paraffin for carpal tunnel syndrome (paraffin hand therapy). There were three groups in this study:
CON group (n = 36) – Control group with a fabricated nighttime orthosis which holds the wrist in a neutral position.
KIN group (n = 37) – This group was fabricated a nighttime orthosis which holds the wrist in neutral position AND kinesiotape was applied 2 times per week for a 3-week period.
PARA group (n = 37) – This group was fabricated a nighttime orthosis which holds with wrist in a neutral position AND paraffin treatment 3 times a week for a 3-week period.
In the Weeds
110 patients were selected for this study based on the inclusion criteria which included symptoms for less than a year, no previous carpal tunnel injections or surgery, no therapy that specifically targeted CTS in the past 6 months, no co-morbidities such as diabetes and no trauma to the wrist or its surrounding structures. When comparing hand strength, the KIN group showed a greater improvement than the CON and PARA groups at the 3 month mark. The KIN group also showed a significant decrease in pain through the use of the VAS scale from pre-treatment to the 3 month mark with a decrease from 7.1/10 to 2.1/10. Kinesiotape application: Tape was applied distal to proximal from distal palmar crease at 3rd, 4th, and 5th metacarpals to 5 cm short of medial epicondyle with paper off tension. Tape was applied across the wrist with 20% tension across the carpal tunnel with 0% tension on the ends of the tape.
Bringing it Home
The results found that the use of kinesiotape and a nighttime orthotic proved most effective in reducing pain scores in patients with CTS. This gives therapists an evidence based treatment option for conservative management of CTS with the use of the kinesiotaping and splinting. The daytime kinesiotaping allows for functional use of the involved hand without having to wear an orthosis during the day. It is worth noting that kinesiotape tends to stick differently to different clients and usually needs to be reapplied every 3-5 days. That makes this a short-term solution and an adjunct to the treatment rather than the primary method of management.
The treatment provided was very detailed, giving therapists the tools to re-create these methods in a clinical setting. When reporting their results, authors state an improvement in grip strength, but do not include these numbers in their article.. This may be an important statistical number to this particular population as many individuals who have CTS deal with a lack of grip strength. Overall this is a very well written article giving therapists another tool for their toolbox when treating individuals with CTS.

Hand therapists may feel they are in a constant battle with scar tissue. It can limit ROM, cause pain, impede other structures, and leave a less than desirable appearance. Scar tissue starts forming as early as 2 weeks after an injury and can continue forming for up to 2 years. The earlier action is taken…Read More
