You can do several exercises to stretch and strengthen your arm muscles. Ask your doctor or a physical therapist for more information and suggestions. Here are a few samples to get you started:

Finger stretch:

Touch your fingers to your thumb and put a rubber band around them, including your thumb

Slowly open your thumb and fingers all the way, then close them

Repeat up to 25 times

Do this stretch up to three times a day. If it gets too easy, try two rubber bands.

Wrist flexor stretch:

Hold your arm straight out so your elbow isn’t bent and your palm faces up

Use your other hand to hold the fingers of your outstretched hand and bend it back toward your body until you can feel it in your inner forearm

Hold for 15 seconds

Repeat three to five times

Do this two to three times a day. You can hold it for up to 30 seconds and work your way up to repeat five to 10 times instead of three to five.

Wrist flexor/extensor strengthening:

Grab a 1-pound dumbbell -- or a can of beans -- and take a seat

Support your forearm on your thigh or the edge of a table so that your wrist hangs over the edge

Hold the weight in your hand with your palm facing up

Raise your hand slowly, then lower it slowly -- your arm stays on your thigh as your hand bends up and down at the wrist

Repeat 10 times
