Carpal Tunnel Syndrome (CTS) is a common condition resulting from the compression of the median nerve as it passes through the narrow passageway of the wrist. Symptoms typically involve pain, numbness, and tingling in the hand and fingers, particularly the thumb, index, middle, and half of the ring finger. Carpal tunnel release surgery is performed to relieve this pressure by cutting the transverse carpal ligament, which forms the roof of the tunnel, thereby increasing space for the nerve and tendons. While the surgery addresses the physical compression, a structured rehabilitation program of exercises is necessary to achieve a full recovery and restore strength and function to the hand and wrist.
Understanding the Initial Post-Surgical Phase
The time immediately following carpal tunnel surgery focuses on protection and managing the body’s response to the procedure. Post-operative care involves incision management to prevent infection and promote healing. Swelling is common, and managing it for comfort and recovery is typically done by keeping the hand elevated above the heart and applying ice as directed by the surgeon.
A post-operative splint or bulky dressing is usually worn for the first one to two weeks to protect the surgical site and restrict wrist motion. During this period, avoid lifting objects heavier than one or two pounds or performing strong gripping actions. Gentle movements of the fingers are often permitted and encouraged within one to three days after the operation to prevent stiffness and reduce swelling.
Early Range of Motion and Nerve Gliding
The first phase of active rehabilitation begins with gentle, non-resistive exercises designed to encourage motion and prevent adhesions (tissues sticking together and restricting movement). These movements often start within the first week after surgery, but always follow the surgeon’s specific timeline. Finger tendon gliding exercises are a primary focus, involving a sequence of positions to move the flexor tendons within the carpal tunnel.
A common gliding sequence moves the fingers from a straight position to a hook fist, then to a straight fist, and finally to a full fist, followed by returning to the straight position. These motions are performed slowly and repeatedly to prevent the tendons from scarring down, which can limit the ability to make a complete fist. Gentle wrist range of motion exercises, such as small arcs of flexion and extension, are introduced shortly after within a comfortable range and without causing pain. Median nerve gliding exercises are also performed to help the nerve move freely within the tunnel and minimize scar tissue formation.
Progressive Strengthening and Dexterity Exercises
Once the surgical wound is closed and sufficient healing has occurred (typically around two to four weeks post-surgery), the focus shifts to regaining strength and dexterity. This phase introduces resistance to rebuild the hand and forearm muscles that may have weakened from disuse. Grip strengthening is foundational, often utilizing therapy putty or a soft rubber ball, where the patient squeezes the material before releasing.
Pinch strengthening exercises restore the ability to grasp small objects, involving pressing the thumb tip against the tips of the other fingers (e.g., a tip-to-tip or lateral key pinch). Light resistance is gradually added to wrist movements, such as flexion, extension, and side-to-side movements, using light weights or resistance bands. Fine motor skills, necessary for daily tasks, are practiced by picking up small items like coins or beads, or by practicing buttoning a shirt. Strengthening exercises must be progressed slowly, only moving to higher resistance when the current level can be performed without discomfort.
Recognizing Complications and When to Consult a Therapist
Recognizing signs of potential complications is an important part of post-operative care. Signs of infection, such as increased redness, warmth, discharge from the incision site, or a fever, require immediate medical attention. Persistent or worsening pain that does not respond to medication, or a return of the original numbness and tingling after a period of improvement, should be reported to the surgeon.
Professional guidance from a physical or occupational therapist specializing in hand therapy is often beneficial for a complete recovery. Consultation is advisable if progress stalls, if stiffness or limited range of motion persists, or if the surgical scar remains tender or restricts movement. A therapist provides personalized scar management techniques, advanced exercises, and specialized treatment to ensure the return to full hand function.
