What Causes Hand Dysfunction?

There are many common causes of hand dysfunction:

1)     damage to bones and soft tissues;

2)     vascular or lymphatic disease (such as lymphedema after breast cancer surgery leading to limited upper limb movement);

3)     peripheral nerve and central nervous system damage, etc.

Only by knowing the exact cause of hand dysfunction can doctors and therapists give specific treatment solutions.

Here is analysis on hand dysfunction caused by some common diseases:

1, bone and soft tissue damage

Taking hand fractures as an example, patients with fractures often have sensory and motor dysfunction. Patients will have decreased joint activity, decreased muscle strength and pain, etc., resulting in limited ability of daily life activities.

2, peripheral nervous system damage

Common injuries include brachial plexus injury at birth, radial nerve, ulnar nerve and median nerve injury caused by various reasons. The brachial plexus injury at birth often leads to the hand upper limb dysfunction and the development of the involved limb. The injury of radial nerve, ulnar nerve and median nerve results in the dysfunction of muscle innervation and regional sensory disturbance, resulting in the abnormal posture of the upper limb hand.

3, central nervous system damage

Central nervous system injury is a common cause of hand dysfunction. For common diseases such as stroke, 55% – 75% of patients will leave limb dysfunction after stroke. More than 80% of them have hand dysfunction, of which only 30% can achieve complete recovery of hand function.

4, vascular and lymphatic diseases

5, chronic diseases
