What is it?
Carpal tunnel syndrome occurs when the median nerve is compressed as it passes through a narrow canal in the wrist. Numbness and tingling in the thumb, index and middle fingers, often worse at night, may be felt.
Diagnosis uses examination and, if needed, a nerve conduction study (EMG). Mild cases may be managed with night splints, activity changes and exercises; for advanced cases, surgical release is considered.
The duration and severity of symptoms differ between people; the suitable approach is determined by reading the examination and test results together.
Who is it assessed for?
- People with numbness and tingling in the fingers
- People woken at night by hand numbness
- People who have started dropping things
- People working with keyboards, tools or repetitive hand movements

Questions
Is an EMG necessary?
Not always. Your doctor decides based on findings and how long the symptoms have lasted.
What does a night splint do?
It keeps the wrist in a neutral position to reduce pressure on the nerve during the night.
Can it occur during pregnancy?
Yes, fluid retention in pregnancy can cause it. The approach is then planned separately.
