The interlocking finger test is a method used to test the strength and flexibility of the wrists and wrists and can also be used to measure motor coordination. This test involves two people, each with their hands interlocking the fingers of the other hand. The person on the bottom should try to pull their fingers away from the other person's hold while the top person should resist the pull.
If the person on top can easily break the grip and the person on the bottom cannot move their fingers away from the grip, this indicates low strength and flexibility in the wrists and in the muscles surrounding the wrists. On the other hand, if the grip is strong and the person on the bottom can easily pull away from the grip, this indicates strong wrists and good muscle coordination.
The interlocking finger test is not a definitive way to determine the strength and flexibility of the wrists, but can provide a general overview of the wrist's capabilities. To get a more comprehensive view, it is recommended to consult with a physical therapist or occupational therapist who can conduct more comprehensive wrist evaluations.
