Immediately following carpal tunnel surgery, it is normal to expect a decrease in grip strength and finger dexterity. However, there are specific exercises that can help you regain full function of the hand and fingers. Before beginning an exercise program after surgery, be sure your surgeon has cleared you for rehabilitation. It is likely that a physical therapist will guide you through specific exercises during the rehabilitation process.
Open and Close Fist
Regaining lost grip strength will improve your ability to use your hand to perform everyday activities. Opening and closing your fist will work to both increase your grip strength and to relieve any swelling of your fingers, hand and wrist. To begin this exercise, sit with your elbow supported on a table and your palm up. Slowly extend your fingers and thumb as far and as straight as possible. Hold this position for three seconds. Slowly close your fist as much as possible. Hold the fist for three seconds. Repeat five times, twice per day.
Thumb Opposition
Regaining thumb and finger dexterity is crucial for activities like typing, buttoning a shirt or holding a pen. To begin the opposition exercises, sit with your elbow supported on a table and your palm up. Slowly touch the tip of your thumb to the tip of each finger, starting with your index finger. Be sure to move both the thumb and the finger; do not only bring the finger to the thumb. To isolate just the thumb, practice touching the tip of the thumb to the base of each finger, where it meets the hand. This exercise will also work on redeveloping your pinch grip.
Therapy Putty
Putty is used extensively in hand therapy to develop gross motor strength and control of the hand. Therapy putty comes in a variety of densities, which make them easier or harder to squeeze. Start with a putty of the lowest resistance. Work the putty with all fingers and your thumb. Be versatile; you can roll the putty into a ball, or twist and pull it apart with your hands. Work the therapy putty for three to five minutes, twice per day.
Tennis Ball Squeeze
To increase the intensity of grip-strength exercises, resistance is needed. Using a tennis ball is an excellent way to increase grip strength. Start with your elbow bent and by your side. Hold the tennis ball in the surgical hand. Squeeze the tennis ball tightly in your fist. Hold the squeeze for three to five seconds, and then relax. Repeat this exercise 10 times, twice per day. This exercise may be too difficult if you have just had your carpal tunnel surgery.
