Can nerve entrapment cause weight loss, muscle wasting and muscle weakness.

Can nerve entrapment cause weight loss,  muscle wasting and muscle weakness.

No and Yes: Motor nerve entrapment can definitely cause muscle wasting & weakness - but only of a particular muscle or muscle group innervated by that nerve. It's unlikely to cause weight loss except if you lose a large amount of muscle mass.If generalized weight loss &/or generalized muscle weakness is occurring, you need a proper medical evaluation to determine cause; it's unlikely to be nerve entrapment. ...Read more

Could shoulder atrophy cause neck muscle weakness?

Could shoulder atrophy cause neck muscle weakness?

very unusual: They are likely related to a similar cause. The potential list of causes can range from; poor postural mechanics, nerve root dysfunction from the neck region, muscular dystrophy and even some types of arthritis.

Differentiate between duchenne and spinal muscular atrophy?

Differentiate between duchenne and spinal muscular atrophy?

Muscle vs motor neur: Duchenne muscular dystrophy is a disease of the muscles wherein the muscles degenerate and are replaced by fibrous and fatty tissue. Spinal muscular atrophy may look similar, but it is not a dystrophy. It is a disease of motor neurons. It is an inherited recessive disease. ...Read more

What is loss of normal lumbar lordosis paraspinal muscle spasm?

What is loss of normal lumbar lordosis paraspinal muscle spasm?

Lumbar lordosis: Lumbar lordosis is a normal inward curve of our lower spine. Our natural spinal curvature functions as a cushioning effect during movement. When the muscles that lie along the sides of the spine become tense with spasm, they pull the spine straighter than usual. This results in discomfort. ...Read more

Can cervical spondylosis cause muscle weakness in extremities?

Can cervical spondylosis cause muscle weakness in extremities?

Yes: In some cases, cervical spondylosis results in a narrowing of the space needed for the spinal cord or nerve roots. If this occurs, your symptoms may include numbness and weakness in the arms, hands, and fingers. Trouble walking, loss of balance, or weakness in the hands or legs. Muscle spasms in the neck and shoulders. ...Read more

What are the symptoms of neurogenic atrophy in thenar muscle from nerve injury?

Thenar atrophy: Thenar muscle weakness results in thumb abduction weakness. This movement is holding the thumb straight up when the back of your hand is turned down (not shown in the picture). It should be able to overcome some resistance to adopt this position. You may also see a dimple in the muscle area at the base of your thumb. ...Read more

What different between muscle weakness and muscle atrophy?

One is observed: Generally speaking, muscle weakness is something a patient perceives and something that we can test for in physical examination by doing a manual muscle test, etc. Atrophy is something we observe or visualize. In some cases they can be caused by the same thing (ex. nerve injury, immobilization, joint trauma), sometimes they are separate issues. ...Read more

Can a slipped disk cause generalized muscle fasciculations?

Can a slipped disk cause generalized muscle fasciculations?

Fasciculations: Fasciculations are muscle contractions easily seen by the naked eye. This condition usually is secondary to degeneration of parts of the spinal cord. They can be seen with als, spinal dystrophies, polio, and dilations of the central fluid canal within the spinal cord (syrinx). They are not typically seen with "slipped discs.". ...Read more
