Thumb Mobility

Muscles worked

Setup

1. Sit comfortably next to a flat bench or table.
2. Place your forearm flat on the surface with your palm facing upward.
3. Ensure your wrist is in a neutral, relaxed position and your fingers are loose.

How to do it

1. Slowly move your thumb across your palm to touch the base of your pinky finger, exhaling as you reach.
2. Extend the thumb as far back and away from the palm as possible, inhaling as you open the hand.
3. Perform slow, controlled circles with the thumb in both directions, ensuring the movement comes from the base of the thumb.
4. Maintain a slow, deliberate tempo, spending 3-5 seconds on each full rotation or stretch.

Form checklist

• Keep your wrist and other four fingers completely still and relaxed.
• Move only through a pain-free range of motion.
• Focus the movement at the CMC joint, located at the very base of the thumb near the wrist.
• Avoid shrugging your shoulders or tensing your forearm during the movement.

Pro tips

• Imagine drawing the largest circle possible with the tip of your thumb to maximize joint lubrication and capsule space.
• For the opposition phase, try to touch the tip of the thumb to the tip of each finger sequentially to improve fine motor control.

Make it harder

• Loop a small elastic therapy band around your thumb and the back of your hand to add resistance during the extension and abduction phases.
• Perform the movements while lightly gripping a tennis ball with your other four fingers to increase the stability demand.
