A disease that may cause a restricted range of motion is arthritis, osteoarthritis, Cerebral Palsy, Ankylosing spondylitis, stroke, Parkinson's disease, muscle disorders like muscular dystrophy, congenital torticollis and even frozen shoulders, adhesive capsulitis, Legg-Calve-Perthes disease and joint infections.
Major causes of having a restricted range of motion are osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, cerebral palsy and muscular dystrophy.
Cerebral palsy, stroke and Parkinson's disease can cause muscle stiffness and loss of voluntary control.
Even severe injuries like fractures and tears and swelling and tenderness around your joints and muscle stiffness can cause you to have a restricted range of motion.
And even a lack of hip internal rotation can cause someone to have a restricted range of motion.
With a lack of hip internal rotation, you might also have difficulty with your everyday movements, such as getting out of a car or putting on your clothes, which all require the crucial range of motion.
Your lumbar spine may also try to compensate for the lack of hip rotation and cause muscle tension, pain and misalignments.
Your knees are also not designed to rotate, so when your hip rotation is limited, your knees can bear the brunt of the stress and increase your risk of injury.
And you might also notice that your feet or knees are turning inward or caving in during walking or other movements because your body is trying to find a new and less efficient way to move.
And tasks which involve any twisting of your thigh inward, like getting into a car or other vehicle or putting on your clothes can become challenging or uncomfortable.
And limited internal rotation on one side can also result in uneven positioning and contribute to back pain.
A lack of hip internal rotation can occur due to sedentary lifestyles, muscular imbalances etc.
The muscles that are responsible for hip internal rotation might be weak or not working properly and prolonged sitting can also overactivate hip flexors and underactivate other hip muscles, which result in restricted internal rotation.
