Preventing the Ache: The Correct Way to Position a Weak Arm After a Stroke
How to Support a Weak or Paralyzed Arm While Sitting in a Chair
After a stroke, weakness in your arm can cause shoulder pain. Pain makes it hard to move, which can lead to avoiding using your arm altogether.
Fortunately, proper arm positioning and simple supports can protect your joint, reduce discomfort, and keep you safe at home.
How to Support a Paralyzed or Weak Arm While Sitting in a Chair to Prevent Shoulder Pain
When sitting in a chair, gravity constantly pulls down on a weak arm. Without strong shoulder muscles to hold the joint together, this pull causes pain and stretching.
Follow these step-by-step instructions to properly support your arm while sitting in an armchair or wheelchair:
Sit all the way back: Make sure your hips and back rest firmly against the back of the chair. Keep your feet flat on the floor or on footrests.
Place a pillow on the armrest: Set a firm pillow on top of the chair's armrest (or on a wheelchair lap tray).
Support from elbow to fingertips: Rest your forearm on the pillow with your elbow bent at a comfortable 90-degree angle. The pillow must support your elbow, forearm, wrist, and hand. Do not let your hand dangle off the edge.
Keep arm to the side of your body: Avoid brining your hand towards your stomach for long periods of time. Your hand towards your belly can encourage tightness in your shoulder. An arm trough placed in a wheelchair can help maintain the right position.
Keep your hand open and flat: Let your palm rest flat on the pillow with fingers spread naturally. Avoid resting your hand on your belly for long periods, as this causes joint stiffness in your shoulder and elbow.
Check the height: Look in a mirror or ask a caregiver to check your posture. Your supported shoulder should look level with your other shoulder—not hitched up too high or drooping too low.
Understanding Shoulder Subluxation After a Stroke
After a stroke, the muscles holding your arm bone in its shoulder socket can become weak. When these muscles weaken, gravity pulls the top of the arm bone slightly out of the socket. Occupational therapists call this partial separation shoulder subluxation.
Some people feel sharp pain from subluxation. Others feel no pain at all, but the joint is still at risk for damage. Proper support keeps the joint aligned so the surrounding tissues can rest and heal.
Choosing the Right Slings and Supports
Slings offer additional help, but different slings serve different purposes.
The GivMohr Sling
A common option is the GivMohr Sling. This device wraps around your uninjured shoulder and holds your weak arm in a natural position.
Best for: Standing, transferring, and walking. It prevents gravity from pulling your arm down while you move.
Important note: The GivMohr Sling is designed for standing and walking. When sitting, rely on pillow positioning on an armrest or tray instead.
Shoulder Support Braces
Braces like the Ottobock Omo Neurexa Plus wear under or over clothing. They pull the arm bone up into the joint socket.
Best for: Continuous alignment throughout the day.
Important note: These braces can be tricky to put on with one hand, so you may need help from a caregiver.
Daily Moves to Avoid: Protecting Your Shoulder
Caregivers and family members must take extra care when helping someone move.
Never pull on the weak arm: Never pull on a weak arm to help someone stand, sit up, or turn in bed. Pulling stretches the joint capsule and directly causes subluxation and severe pain.
Lift from the trunk or hips: When helping someone move, hold them around their waist, hips, or trunk. Always guide the weak arm gently so it stays close to the body.
Check for reduced feeling: Weakness often comes with low sensation. The person may not feel if their hand is trapped under their thigh or bent unnaturally. Always visually check where the hand and wrist are placed before moving.
