C.J. Allen Upper Extremity & Hand Therapy provides occupational therapy across Suffolk County from offices in Hauppauge and Smithtown. Unlike general occupational therapy practices, ours is confined to one area of the body — the hand, wrist, elbow and shoulder — which is what allows the depth of specialization our patients come for.
Occupational Therapy for the Upper Extremity
Occupational therapy is concerned with participation: whether you can carry out the activities that make up your day. For upper-extremity patients that means dressing, cooking, writing, driving, working and caring for family. Restoring range of motion is a means to those ends rather than the end itself.
Who We Treat
- Post-surgical patients — tendon repairs, fracture fixation, joint reconstruction, nerve procedures.
- Injury patients — fractures, lacerations, crush injuries, sprains.
- Arthritis of the hand, thumb and wrist.
- Nerve compression — carpal tunnel, cubital tunnel.
- Work-related injuries and return-to-work planning.
- Neurological patients regaining hand function after stroke.
- Overuse and repetitive strain conditions.
Two Locations Across the County
Our Hauppauge office at 2108 Joshuas Path serves central and western Suffolk — Islandia, Central Islip, Brentwood, Ronkonkoma, Holbrook, Bohemia and surrounding areas. Our Smithtown office at 290 E Main St serves the North Shore — St. James, Kings Park, Nesconset, Commack, Lake Grove and the Smithtown township. Patients may use whichever is more convenient, and can switch between them.
Certified Hand Therapists
Our therapists hold or are working toward the Certified Hand Therapist credential, which requires a minimum of three years' clinical experience, at least 4,000 hours of direct upper-extremity practice, a comprehensive examination, and recertification every five years. It is a demanding credential and comparatively rare, and it is the clearest indicator that the person treating your hand has spent years doing exactly that.
One-on-One Treatment
You work with the same therapist for your full session, every visit. Progress in upper-extremity rehabilitation is measured in small increments, and consistent attention is what identifies a plateau early enough to change course.
Custom Orthoses Made On Site
Splints are fabricated in the clinic and molded to your hand rather than selected from a shelf. Because they are made here, adjustments happen during your appointment as swelling and motion change.
Coordinating With Surgeons Across Long Island
A significant portion of our caseload arrives by direct referral from hand surgeons throughout Suffolk and Nassau. We follow protocols precisely, document and report progress, and flag concerns early rather than at discharge.
What Your First Visit Involves
A thorough evaluation of motion, strength, sensation, swelling and function, plus a specific account of the activities you are unable to perform. Those tasks become the measurable goals, which keeps treatment anchored to something that matters to you rather than to numbers alone. You leave with a plan, a realistic timeline and a home program.
Do I Need a Referral?
Bring your prescription, surgeon’s protocol, or referral to your first visit and we’ll build your treatment plan from there. If you’re not sure whether you need a referral, give us a call and we’ll sort it out with you.
Your Home Program
Most of the progress happens between appointments. We prescribe a short, specific program rather than a long handout, verify technique in the clinic, and advance it as you improve. Done consistently it is usually the single largest factor in how quickly you finish.
Insurance and Scheduling
Most insurance accepted — our team will assist with insurance verification and help coordinate your care. Call (631) 761-6996 or request an appointment online — most new patients are seen within a few days.
Conditions We See Most Often
Most of what arrives at an upper-extremity practice falls into a handful of categories, and the category shapes the plan more than the diagnosis label does.
- After surgery — tendon repairs, fracture fixation, joint reconstruction, nerve decompression and release procedures, where the surgeon's protocol sets the boundaries.
- Fractures of the fingers, hand, wrist and forearm, including the stiffness that follows a period in a cast.
- Tendon problems — tendonitis at the wrist and thumb, trigger finger, and overuse conditions that build gradually rather than starting with an injury.
- Nerve conditions including carpal tunnel and cubital tunnel, both before and after surgical treatment.
- Arthritis in the thumb base, fingers and wrist, where the aim is protecting function rather than reversing the condition.
- Traumatic injuries — crush injuries, lacerations, amputations and the complex cases that follow them.
What a Certified Hand Therapist Is
CHT is a post-professional certification. It requires an occupational or physical therapy licence, several thousand hours of direct practice specifically in the upper extremity, and a comprehensive examination, with recertification at intervals rather than once for life.
The practical difference is narrowness. A therapist who works only on the shoulder, elbow, wrist and hand sees the uncommon presentations often enough to recognise them — and knows which ones need a surgeon's opinion rather than another week of therapy.
When the Condition Is Ongoing
Not everything is an injury that resolves. Arthritis, chronic tendon conditions and long-standing nerve compression are managed rather than cured, and the honest goal is keeping function and comfort as high as possible for as long as possible.
That usually means a combination: joint protection technique so daily tasks load the hand differently, orthoses worn at specific times rather than constantly, activity pacing, and adaptations to the tools and tasks that cause the most trouble. It is less dramatic than post-surgical rehabilitation and often makes more difference to daily life.
Pain, and What Actually Helps
Pain in the hand and wrist has causes that respond to different things, which is why a single approach rarely works. Inflammatory pain often settles with rest from the aggravating activity, an orthosis that stops the provocative movement, and graded reintroduction. Stiffness-related pain frequently improves as motion returns. Nerve pain behaves differently again and can worsen with the exercise that helps other problems.
Getting that wrong is common and costly — pushing through nerve pain tends to make it louder. Part of the first assessment is working out which kind of pain you have.
