What Is a Hand Therapist and What Do They Treat?

A hand therapist is an occupational therapist or physical therapist who specializes in treating injuries and conditions of the hand, wrist, elbow, and forearm. To earn the Certified Hand Therapist (CHT) credential, a clinician needs at least five years of clinical experience, a minimum of 4,000 hours of direct practice in hand therapy, and a passing score on a national certification exam.1Journal of Hand Therapy. Thirty years of hand therapy: The 2014 practice analysis The scope of what these specialists treat is surprisingly broad, stretching from broken fingers and severed tendons to chronic arthritis, nerve damage, and conditions most people have never heard of.

What Makes a Hand Therapist Different from a Regular Therapist

Any occupational or physical therapist can legally treat your hand. The difference with a certified hand therapist is depth of training. The 4,000-hour requirement translates to roughly two full years of nothing but hand and upper-extremity work before the clinician even sits for the certification exam.1Journal of Hand Therapy. Thirty years of hand therapy: The 2014 practice analysis That concentrated experience matters because the hand is an unusually dense piece of anatomy. Tendons, nerves, small joints, and delicate ligaments are packed tightly together, and a few millimeters of scar tissue in the wrong spot can mean the difference between a finger that bends normally and one that does not.

One of the defining competencies of hand therapists is fabricating and fitting orthoses, the technical term for splints and braces. A practice analysis of certified hand therapists found that fabricating custom orthoses and issuing pre-made ones is considered one of the most critical tasks in the profession.2Journal of Hand Therapy. The 2019 practice analysis of hand therapy and the use of orthoses by certified hand therapists These are not off-the-shelf wrist braces from a pharmacy. Hand therapists heat sheets of thermoplastic material, mold them directly on your hand, and trim and adjust the fit so the splint holds damaged structures in exactly the position they need to heal while still allowing whatever movement is safe.

Carpal Tunnel Syndrome and Nerve Compression

Carpal tunnel syndrome is probably the single most common reason someone ends up in a hand therapist’s clinic without having had surgery first. The condition involves pressure on the median nerve as it passes through the wrist, causing numbness, tingling, and eventually weakness in the thumb and fingers. Hand therapy for carpal tunnel typically combines splinting with specific exercises.

Splinting works in part by reducing swelling inside the nerve itself. An MRI study showed that after one week of splinting and exercise, fluid buildup within the median nerve dropped by about 11%, which was accompanied by improvements in symptoms and hand function. Patients who only received advice to stay active did not show the same reduction in nerve swelling.3PubMed. Effect of splinting and exercise on intraneural edema of the median nerve in carpal tunnel syndrome–an MRI study to reveal therapeutic mechanisms A randomized trial further found that a splint supporting both the wrist and the finger joints in a neutral position may outperform the standard wrist-only splint in reducing symptoms.4PubMed. Efficacy of a fabricated customized splint and tendon and nerve gliding exercises for the treatment of carpal tunnel syndrome: a randomized controlled trial

Beyond splinting, hand therapists prescribe gliding exercises designed to help tendons and nerves slide more freely through the carpal tunnel. Research comparing tendon gliding exercises with nerve gliding exercises found that while both approaches improved symptom severity and pain, tendon gliding combined with conventional treatment led to broader improvements in hand function and quality of life.5American Journal of Physical Medicine & Rehabilitation. The Comparative Effectiveness of Tendon and Nerve Gliding Exercises in Patients with Carpal Tunnel Syndrome Hand therapists use this kind of evidence to decide which combination of exercises and splints to start with before anyone considers a surgical referral.

Tendon Injuries and the Delicate Balance of Early Movement

Flexor tendon injuries in the fingers are one of the most technically demanding problems in hand therapy. When a tendon is surgically repaired, the hand therapist has to walk a tightrope: too much movement too soon risks snapping the repair, but too little movement lets scar tissue glue the tendon to surrounding structures, leaving the finger stiff. The timing and type of post-surgical exercise protocol can make or break the outcome.

A randomized trial compared an “active place-and-hold” approach, where patients gently hold their fingers in a bent position, against a purely passive motion approach where the therapist or the other hand moves the fingers. At final follow-up, the active group had significantly more finger motion (averaging about 156 degrees of total finger-joint movement versus 128 degrees) and higher satisfaction scores, without an increased risk of the tendon re-rupturing.6Journal of Bone and Joint Surgery. Zone-II Flexor Tendon Repair: A Randomized Prospective Trial of Active Place-and-Hold Therapy Compared with Passive Motion Therapy A systematic review and meta-analysis confirmed this pattern: early passive motion protocols carried a lower rupture risk but resulted in more stiffness, while early active motion protocols achieved better range of motion with a somewhat higher chance of rupture.7PubMed. Flexor tendon repair rehabilitation protocols: a systematic review A second meta-analysis found that the place-and-hold method specifically did not significantly increase rupture rates compared to passive motion, making it an appealing middle ground.8PubMed. Outcome of Surgical Repair and Rehabilitation of Flexor Tendon Injuries in Zone II of the Hand: Systematic Review and Meta-Analysis

This is a good example of why the hand therapist’s judgment matters. These protocols require constant adjustment. The therapist monitors healing week by week, decides when to allow more active movement, and fabricates protective splints that change as the tendon strengthens. Getting it right demands familiarity with the surgical repair, the specific tendon involved, and the patient’s healing trajectory.

Wrist and Hand Fractures

Distal radius fractures, the kind of broken wrist you get from catching yourself during a fall, are one of the most common fractures in adults. After surgical fixation, hand therapists guide recovery through exercises aimed at restoring wrist motion, forearm rotation, and grip strength. An interesting question in this space is whether you actually need to go to the clinic regularly or whether a well-designed home program is just as effective.

A randomized trial compared patients who attended supervised sessions with a certified hand therapist against patients who received a home exercise program that was designed and periodically monitored by a CHT. At 12 weeks, there was no significant difference between the groups in pain, wrist motion, forearm motion, or grip strength, and both groups experienced large improvements.9PubMed. Therapist-supervised hand therapy versus home therapy with therapist instruction following distal radius fracture The takeaway is not that hand therapy is unnecessary for fractures. Both groups still relied on a hand therapist’s expertise for the program design and monitoring. Rather, it suggests that for straightforward fractures in motivated patients, frequent in-clinic visits may not always be needed once the program is set up properly.

Thumb and Finger Arthritis

Osteoarthritis at the base of the thumb is extremely common, especially in women over 50, and it can make everyday tasks like opening jars or turning keys painful. Hand therapists play a central role in managing this condition conservatively, using a combination of splinting, exercise, and joint protection education.

A randomized controlled trial found that patients with early-stage thumb arthritis who wore a splint had significantly less pain, stiffness, and disability compared to a non-splint group, along with measurable gains in grip and pinch strength.10PubMed Central. The effects of hand splinting in patients with early-stage thumb carpometacarpal joint osteoarthritis: a randomized, controlled study A separate study with one-year follow-up found that adding splinting and exercise to a joint protection program produced greater improvements in pain, stiffness, grip force, and daily activities than the joint protection program alone.11PubMed. Effects of a hand-joint protection programme with an addition of splinting and exercise: one year follow-up

Not all splints are equal, though. A recent network meta-analysis that compared different non-surgical treatments for thumb arthritis found that a rigid splint immobilizing both the thumb base joint and the adjacent knuckle joint was the only intervention that showed a clinically meaningful reduction in both pain and disability at medium-term follow-up.12PubMed Central. What Are the Most Clinically Effective Nonoperative Interventions for Thumb Carpometacarpal Osteoarthritis? An Up-to-date Systematic Review and Network Meta-analysis This is exactly the sort of detail a hand therapist tracks: which splint design, covering which joints, for which type and stage of arthritis.

Overuse Injuries Like De Quervain’s Tenosynovitis

De Quervain’s tenosynovitis is an inflammation of the tendons on the thumb side of the wrist that causes sharp pain when you grip, twist, or make a fist. It is sometimes called “mommy thumb” because it often strikes new parents from the repetitive motion of lifting a baby, though it can happen to anyone who overuses those tendons. Conservative treatment typically focuses on reducing inflammation and correcting the movement patterns that caused the problem.

A case report documented complete resolution of De Quervain’s symptoms with a conservative approach that included activity modification, soft-tissue mobilization, and a targeted eccentric exercise program. At six-month follow-up, the patient reported no recurrence.13PubMed Central. Conservative management of De Quervain’s stenosing tenosynovitis: a case report While a single case report does not prove a universal treatment plan, it illustrates the hand therapist’s toolkit for overuse injuries: identify the aggravating activity, calm the inflammation with splinting and manual techniques, then rebuild strength so the tendons can handle normal demands again.

Sensory Rehabilitation After Nerve Repair

When a nerve in the hand is cut and surgically repaired, the nerve slowly regrows, but the brain’s map of sensation from that hand gets scrambled in the interim. Hand therapists use sensory re-education programs to help the brain reinterpret signals from the healing nerve. Techniques like mirror therapy, where the patient watches the reflection of their uninjured hand performing movements, can begin early, before the repaired nerve has even started sending signals back to the brain.

A randomized controlled trial of early sensory re-education using mirror therapy after peripheral nerve repair found that the approach takes advantage of the brain’s ability to reorganize itself. After nerve injury, the brain regions that normally process sensation from the injured hand go quiet. Methods like mirror therapy and sensory gloves aim to keep those brain areas active and primed to reconnect with incoming nerve signals once regrowth occurs.14PubMed Central. Early sensory re-education of the hand after peripheral nerve repair based on mirror therapy: a randomized controlled trial This kind of treatment requires patience from both the therapist and the patient, since nerve regrowth is slow and results can take months to materialize.

Complex Regional Pain Syndrome

Complex regional pain syndrome (CRPS) is one of the most challenging conditions a hand therapist encounters. It typically follows an injury or surgery and involves persistent, disproportionate pain accompanied by swelling, skin color changes, stiffness, and temperature differences in the affected hand. The mechanisms behind CRPS are not fully understood, which makes treatment partly a matter of trying multiple approaches and seeing what helps.

Mirror therapy has been widely investigated for CRPS. A literature review concluded that there is a clear indication for including mirror therapy in the treatment of CRPS, with positive effects on both pain and motor function.15PubMed. Mirror therapy for Complex Regional Pain Syndrome (CRPS)-A literature review and an illustrative case report However, the evidence is not perfectly consistent. A randomized controlled study found that mirror therapy added to routine therapy did not provide extra benefit for pain, function, or other clinical outcomes in post-traumatic CRPS.16PubMed Central. Effects of mirror therapy in post-traumatic complex regional pain syndrome type-1: a randomized controlled study This kind of mixed evidence is common with CRPS, and it is one reason hand therapists treating this condition often draw on a broad set of strategies, including desensitization, graded motor imagery, edema management, and gentle range-of-motion work, adjusting the plan based on how the patient responds.

Dupuytren’s Contracture

Dupuytren’s contracture is a condition where thickened tissue in the palm slowly pulls one or more fingers into a bent position. Treatment usually involves surgery or an enzyme injection to release the contracted tissue, followed by hand therapy to maintain the straightened position. A question that comes up often is whether wearing a splint afterward actually helps.

A systematic review and meta-analysis of post-surgical Dupuytren’s cases found that adding a splint to hand therapy offered no additional functional benefit for most patients after fasciotomy. The researchers noted, however, that splinting may still be useful on a case-by-case basis for patients who develop a recurrent bend after surgery.17PubMed Central. Comparison of Hand Therapy with or without Splinting Postfasciectomy for Dupuytren’s Contracture: Systematic Review and Meta-Analysis After enzyme injection, the picture is a bit different. A study found that patients who wore a nighttime extension splint had significantly less residual contracture at four months compared to those who did not, with the biggest improvements seen in the finger joints closest to the fingertip (the PIP joints), where recurrence tends to be worst.18PubMed. Clinical Effectiveness of an Orthosis After Collagenase Clostridium Histolyticum Injection for Dupuytren Contracture Reported compliance with the splint dropped over time, from about 79% wearing it at least most of the time at one month to 52% at four months, which underscores a real-world challenge hand therapists face: getting patients to stick with a nighttime splint for months.

Scar Management and Wound Care

After surgery or a traumatic injury to the hand, scar tissue management is a significant part of hand therapy. Techniques include silicone gel sheeting, massage, compression, and stretching. The goal is to keep scar tissue soft and pliable enough that it does not tether underlying tendons or joints and limit movement. That said, the evidence base for many specific scar management techniques remains thin. A review in hand therapy literature acknowledged that clinical experience and anecdotal evidence continue to drive many scar treatment choices rather than rigorous trials.19The British Journal of Hand Therapy. Scar Management in Hand Therapy – is our Practice Evidence Based? This is an area where the therapist’s hands-on experience genuinely counts, since a lot of clinical decision-making relies on how the scar looks, feels, and responds to treatment week by week.

Children with Congenital Hand Differences

Hand therapy is not exclusively an adult specialty. Children born with hand anomalies, whether extra fingers, fused digits, underdeveloped thumbs, or other structural differences, often work with hand therapists from infancy onward. The therapist’s role changes depending on the child’s age: in infants, it might involve post-surgical splinting after a reconstructive procedure; in toddlers, it shifts toward helping the child learn to use their hands for play and self-care; and in school-age children, the focus broadens to include handwriting, sports, and independence with daily activities.20PubMed. Hand therapy for children with congenital hand differences Supporting families through the emotional adjustment of raising a child with a hand difference is also part of the job.

The Psychological Side of Hand Injuries

Hand injuries carry a psychological burden that is easy to underestimate. Your hands are central to work, self-care, communication, and physical affection, and losing function even temporarily can trigger anxiety, depression, and frustration. Research has found that hand injuries can cause significant psychological difficulties, and that therapists need to recognize when a patient would benefit from a referral to psychosocial services.21PubMed Central. The Use of Psychosocial Services Post Hand and Upper Limb Injury and Trauma: A Pilot Study In practice, hand therapists are often the clinicians who spend the most time with a patient, week after week, and they tend to notice emotional distress before anyone else on the treatment team does. Part of the skill set is knowing when to address coping strategies within sessions and when to connect the patient with a mental health professional.

Assistive Tools and Robotic Devices

For people with lasting hand impairments, hand therapists also work on the adaptive side of things: finding tools, devices, and ergonomic setups that let someone function as independently as possible. Ergonomic solutions and adapted equipment help with grip and pinch tasks, reduce strain and pain, and allow someone with limited dexterity to engage in daily activities they might otherwise need help with.22Journal of Alternative Complementary & Integrative Medicine. Low-Tech and High-Tech Assistive Tools for Occupational Therapy and Hand Rehabilitation in Patients with Upper-Extremity Sensorimotor Impairment and Disability This ranges from low-tech solutions like built-up handles on utensils and button hooks, to custom-fabricated devices tailored to a person’s specific hand shape and needs.

On the higher-tech end, soft robotic gloves and virtual reality systems are being explored as ways to make repetitive hand exercises more engaging and accessible. Robotic devices can guide the hand through movements that a weakened patient cannot perform alone, and virtual reality adds a game-like element that tends to keep people more involved in their exercises.23PubMed Central. Soft robotic devices for hand rehabilitation and assistance: a narrative review These technologies are still evolving and are not yet standard equipment in most hand therapy clinics, but the direction of research suggests they will become increasingly common as costs come down and evidence accumulates.
