Why does shoulder subluxation occur after stroke?
Why does shoulder subluxation occur after stroke?
In the time just after the stroke, a weak or paralyzed arm often hangs down at the side of the body, subjecting the arm to the effects of gravity and stretching tissues to the point of dislocation. Without the support of the shoulder muscles, the joint capsule stretches causing subluxation.
How long does a subluxation of the shoulder take to heal?
A shoulder subluxation is a partial shoulder dislocation involving the ball of the upper arm bone (the humerus) partially popping out of its socket. Shoulder subluxation can take 12 to 16 weeks to fully heal.
What muscles are affected by shoulder subluxation?
The tendons of the supraspinatus, infraspinatus, teres minor and subscapularis reinforce the joint capsule and limit the range of motion. These muscles, known as the rotator cuff, are the primary mechanism for supporting the shoulder joint and limiting its ROM.
How do you prevent shoulder subluxation after a stroke?
In the early rehabilitation phase, passive range of motion exercises has been shown to effectively prevent shoulder subluxation among stroke patients. Range-of-motion exercises for the shoulder joint include flexion-extension, abduction-adduction and external-internal rotation.
How do you strengthen your shoulders after subluxation?
Static shoulder exercises work the muscles in the shoulder without moving the shoulder itself. For all these exercises, your elbow should be bent to a right angle and your arm should not move. Repeat each one 10 times and hold for 5-10 seconds. Repeat 3 times daily.
