Hand Therapy Specialists

What is a Certified Hand Therapist?

A Certified Hand Therapist (CHT) is an occupational/physical therapist who specializes in the treatment of hands.

They must have a minimum of 5 years postgraduate experience with at least 4,000 hours in hand therapy and have successfully challenged the Hand Therapy Certification Commission exam in order to obtain these credentials. CHT’s are dedicated professionals who have a commitment to meet the highest standards of their profession. The hand and arm have extremely intricate anatomy and complexity. Rehabilitation of the hand and arm requires in-depth knowledge and up-to-date techniques. Certified Hand Therapists have the highest level of competence in the rehabilitation of upper extremity injuries.

Certified Hand Therapists are able to initiate treatment immediately following surgery often while stitches are still in place. Early referral to a hand therapist is effective in preventing further surgeries and obtaining an optimal outcome.
