What muscle group would you lengthen to release or decrease mild extension at the wrist?

To decrease mild extension at the wrist, lengthening the extensors is the appropriate approach. The extensors are the muscles located on the posterior aspect of the forearm and are responsible for extending the wrist and fingers. When the wrist is in a position of extension, these muscles are contracted. By lengthening them through stretching or other techniques, you can help facilitate a more neutral position of the wrist, thus reducing the degree of extension.

Understanding the role of muscle groups is essential in therapeutic contexts. The flexors, found on the anterior aspect of the forearm, primarily function to flex the wrist and fingers, which would not directly aid in decreasing extension. The rotators are associated with movements such as pronation and supination of the forearm rather than wrist extension, and the adductors primarily refer to muscles responsible for moving limbs toward the midline of the body, which is not relevant in the context of wrist extension.
