Tenodesis Effect

Wrist extension naturally encourages finger flexion, making flexor tendon gliding easier. Performing differential tendon glides with the wrist flexed is harder because finger flexion must work against the hand's natural extended posture. The tenodesis effect can be used to adjust the difficulty of tendon gliding exercises. Placing the wrist in slight extension can assist a patient struggling to flex their fingers during tendon gliding exercises. Making a fist is easier with the wrist extended due to the tenodesis effect.
