With the strap crossing the palm to the volar side of the hand, the thumb is placed in a functional position. This W-220 OPP variation introduces thumb opposition, in addition to abduction. In this case, the strap stretches dorsally toward the ulnar side of the hand. The W-220 ABD style splint primarily place the thumb in functional mid palmar/radial abduction. W-220 Product Instructions W-220 ABD - Thumb Abduction The addition of thermoplastic is available to provide more control, such as a thumb web space. Possible indications for either style include CMC dysfunction, osteoarthritis and rheumatoid arthritis, low median nerve injury and some UCL/RCL injuries. Improved functional use of the hand is possible by stabilizing, but not fully immobilizing the CMC joint, while allowing flexion of the thumb IP joint for tip to tip and tripod pinch.

This is an excellent article, and I encourage you to read it for more details.Benik's W-220 Series Thumb Abduction and Opposition Supports are simple thumb sleeves with wrist straps that provide dynamic support to the thumb CMC and MP joints. Shortcomings of the study include a small number of participants, even though it was adequately powered. The IMD is a more accurate way to track clinical changes. Therapists play an important role in managing CMC arthritis specifically thumb CMC adduction contractures. CMC arthritis can cause changes in the joint(s) that lead to loss of palmar and radial abduction and other problems that significantly impact hand function.

RATING: This article was well written and can change the standard of practice for measuring thumb abduction. Making this IMD a great choice for measuring thumb abduction. (21)00041-7/fulltextīRINING IT HOMEL: Through statistical analysis is was determined IMC for measuring radial and palmar abduction had excellent reliability, and the precision was found acceptable to excellent.

Figure 3Radial Abduction IMD Measurement. There were a total of 22 subjects and 28 thumbs.

A digital caliper was used to measure the distance (mm) between these two points. The therapist located and marked the 1st and 2nd metacarpal heads at the dorsal midpoints of the joints. IN THE WEEDS: Two certified hand therapists of differing clinical and educational backgrounds measured the IMD in patients with a confirmed CMC arthritis diagnosis. The purpose of the study was to determine the inter-rater reliability and precision of using an inter-metacarpal distance method test (IMD) on individuals with CMC arthritis A common practice for measuring these contracture(s) is to use goniometric measurements to measure radial and palmar abduction, which has been shown not to have the best reliability. The thumb joint, in particular, is susceptible to arthritis, and these arthritic changes can lead to contractures of the first webspace, known as a thumb adduction contracture. THE SKINNY: Hand osteoarthritis is a common condition seen by hand therapists.
