While they often can be used to indicate the same thing, strictly speaking, "atrophy" means a loss of function due to disuse. "Dystrophy" is more general, meaning "other than normal". The distinction usually comes down to this: something that was originally normal will waste away via atrophy, while something that was never normal to begin with may suffer dystrophy.
atrophy
No, generally these are two separate issues. In flaccid paralysis, the muscles may be intact, but unable to contract due to chemical or electrical problems. Atrophy refers to the loss of muscle strength, tone, and size often due to disuse. Over time, paralysis could lead to atrophy from the disuse.
Good muscle tone reduces the risk of injury during any lifting or moving, including athletics and exercise. It also reduces the effect of age-induce muscular atrophy. Finally, it reduces the risk of being bullied or teased for being weak or flabby!
Bodybuilding is for people to tone up their body and not for muscle.
Hypotonia is low muscle tone and underdevelopment of the muscles. Other terms for the condition include: Low Muscle Tone Benign Congenital Hypotonia Congenital Hypotonia Congenital Muscle Hypotonia Congenital Muscle Weakness Amyotonia Congenita Floppy Baby Syndrome Infantile Hypotonia
People who have casts, splints, or braces on their arms or legs will generally spend several weeks not using the injured arm or leg. This lack of use can result in decreased muscle tone and shrinkage of the muscle (atrophy).

Tone is used to convey or suggest attitude.
The Pitch
A loss of tone does not mean muscle wastage, which many people may think, but it can lead to muscle wastage if it is due to the muscle not being able to contract/function anymore. Muscle wastage is known as atrophy. Low tone is known as hypotonia (the opposite being hypertonia [spasticity]). A muscle with low tone is generally weak against resistance, where as a muscle with high tone has a lot of resistance against a force. Tone is set unconsciously so that we can move fluently, so unless it is loss of tone due to some kind of neurological disorder, then it just means that the muscle is not in a contracted state in any way.
A Muscle Tone .
Disuse atrophy is degeneration and loss of muscle mass. The size, shape, tone, and strength of muscles (including the heart) are maintained with mild exercise and increased with strenuous exercise. Promoting exercise to maintain a patient's muscle tone, joint mobility, and cardiovascular function is an important nursing function.
