Strokes that cause one-sided weakness often have another frustrating consequence: swelling in the affected arm and hand. In a normally-functioning arm, muscle movement helps “pump” tissue fluid throughout the extremity as it circulates within the body. Weakened arm muscles from a stroke are less able to pump, causing fluid to build up towards the bottom of the limb. This fluid buildup results in arm swelling, which is also known as edema. Early recognition and treatment of edema is vital to prevent pain and improve arm function. (1, 2)
Below are various strategies that can be considered if you are experiencing stroke-related edema:
“Dependent” or downward arm positioning can contribute to edema, as tissue fluid will accumulate towards the bottom of a weakened limb. Elevating the limb throughout the day might help reduce fluid pooling and associated swelling. When in bed at night, you can prop up your arm with pillows, ideally above the level of your heart. During the day, you can try to keep your arm higher than your lap by supporting it with pillows, a padded chair armrest, or with an arm trough or lap tray if you are a wheelchair user.
Compression garments for the hand and arm may help push tissue fluid from the bottom of the limb back into bodily circulation. There are various types of compression gloves and sleeves that can be considered for edema. It is best to seek advice from a healthcare professional before purchasing a compression garment, as they often need to be sized for your body to work correctly.
Edema massage can assist with fluid circulation throughout the affected arm. It is best to consult with a therapist or nurse who is also a certified lymphedema specialist to teach you to perform this technique, as it involves specific pressure, speed, and direction of massage strokes on the swollen limb. Massage is contraindicated with some health conditions, and should not be performed if you have blood clots, heart or kidney failure, or certain cancers.
Exercise is an excellent way to manage edema. Whether you can move the affected arm by itself, or you have to move it with the help of your strong arm, getting your muscles to shorten and lengthen can help reduce swelling. Depending on how strong your affected arm and hand are, you may chose to complete active movement exercises with or without additional weights or passive stretches. Both techniques can pump pooled tissue fluid back towards the heart. Exercise also helps maintain joint flexibility and can improve overall strength and arm function. (1 - 3)
If you have arm swelling that also associated with redness, pain, and skin that is warm to the touch, seek medical advice immediately as this might indicate a blood clot. It is always a good idea to discuss edema management strategies with your medical team to find out which techniques might work best for your particular case before beginning a routine.
