Interlocking Thumb Stretch for the Thenar Webspace
This one-page client handout teaches a gentle stretch for the thenar webspace, the web of skin and muscle between the thumb and index finger. The client interlocks both thumbs in front of the body, rests the arms on the abdomen, and holds a light stretch for 2–3 minutes.
Use it when a client needs a simple, low-effort stretch they can do at home. The handout also presents the position as a way to rest the hands between tasks, or as a calming option when the hands are uncomfortable or painful.
The handout was created with Rachel Egan, OTR/L, MS, CHT, COMT-UE.

This handout works well as part of a home exercise program for clients working on thumb and hand mobility. Since the stretch is done with the arms resting on the abdomen, clients can do it sitting or lying down, and it doesn’t need any equipment.
The handout offers two ways to use the position: as a stretch held for 2–3 minutes, and as a resting position for the hands when they’re not in use. That second use gives clients an easy way to fit it into the day, for example while watching TV or reading.
Instructions and Tips
Show the stretch in session before you send the handout home. The handout tells clients to keep their hands relaxed and to apply light inward pressure from the elbows, not by squeezing with the hands. Clients often push too hard at first, so watch their first few tries and coach them toward a gentle stretch.
Before the client leaves, tell them how often to do the stretch and what to do if it brings on pain or makes pain worse. The handout gives a hold time but no frequency, so this is a good place to add your own instructions.
