Exercises do not open the carpal tunnel. Nothing you do with your hand makes the tunnel bigger. What glides can do is help the median nerve move more freely through a space that has become tight, and that helps some people considerably and others not at all.
Which is why the question worth answering is not “what are the exercises” but “am I still at the stage where exercises are the right tool.”
The two that are actually worth doing
Median nerve glides. Start with the arm by your side, elbow bent, palm facing up, fingers and thumb curled loosely. Straighten the fingers and thumb, then straighten the elbow so the arm extends out to the side, palm still up. Finally tilt the head gently away from that arm. Hold two to three seconds, return. Five to ten repetitions, three to five times a day.
Tendon glides. From a flat hand, move through four positions: hook fist (knuckles straight, other two joints bent), full fist, tabletop (knuckles bent, fingers straight), straight fist. Hold each two seconds. Ten cycles, three times a day. These keep the flexor tendons moving independently inside the tunnel rather than as a block.
The rule that matters more than the technique
A nerve glide is not a stretch. You are moving the nerve, not lengthening it, and nerves respond badly to being pulled.
Stop at the first hint of tingling, not at the point of tingling. If the exercise produces symptoms, you have already gone too far.
The honest test is what happens that night. If your night symptoms are worse after a day of glides, you overdid it — halve the repetitions and shorten the range. If they are worse after three consecutive nights, stop and get it assessed rather than pushing through.
What makes it worse
- Wrist flexion stretches. The praying-hands stretch and its reverse both raise pressure inside the tunnel. They are the most commonly shared carpal tunnel exercise online and one of the least appropriate
- Grip strengthening. Putty, grippers, stress balls. The tendons that have to pass through the tunnel get thicker with training. Strengthening is for after the symptoms settle, not during
- Doing them all day. More is not better with a nerve. Five short sessions beat one long one, every time
- Exercises instead of the splint. A neutral wrist splint worn at night is the higher-yield intervention for most people, and glides work better alongside it than instead of it. See which splint, and how long to wear it
When exercises are the wrong tool entirely
This is the part that decides outcomes, and it is the part most exercise articles leave out.
- Numbness that has stopped coming and going. Intermittent numbness means an irritated nerve. Constant numbness means a nerve that is being damaged, and that is a different clinical situation with a shorter runway
- The muscle at the base of your thumb looks flatter than the other side. Compare both palms in good light. Wasting there means motor fibres are already affected
- You drop things, or you cannot feel what you are holding. Not clumsiness. Sensory loss
- Six to eight weeks of consistent splinting and glides with no change. That is a fair trial. Continuing a ninth and tenth week rarely changes the answer
Any of those, and the conversation moves to injection or decompression rather than more repetitions. Nerve recovery after release is reliable when it is done while symptoms are still intermittent, and becomes much less predictable once the numbness has been constant for months.
A realistic timeline
- Week 1 to 2. Nothing much. Night splint may improve sleep before the glides do anything
- Week 3 to 6. If it is going to work, night symptoms reduce in frequency here. Fewer wake-ups before less intensity
- Week 6 to 8. Decision point. Better, hold the course and add load gradually. Unchanged, get reassessed
Background on the condition itself, including what causes it and how it progresses, is in carpal tunnel syndrome: symptoms, treatment and timeline. If surgery is already on the table, carpal tunnel release recovery covers what the months afterwards look like.
