Are there ways to reverse muscular atrophy if you have muscular dystrophy?

Usually not

Muscular_dystrophy
There are some experimental compounds that may prevent or delay atrophy in muscular dystrophy but nothing that uasually brings back muscles that have atrophied already. One should discuss preventative measures as well as possible treatmenst with a neuromuscular neurologist.

How might gene therapy be used to treat muscular dystrophies?

In hopes to cure

Genetic
Gene therapy is targeted at replacing the damaged segments of DNA with more normal copies so that the body can produce adequate dystrophin--the protein missing in duchenne. So far no one has found a method that successfully delivers the gene, largely because it is very big. But there is still a lot of work in this area being done.

What is the difference between spinal & progressive muscular atrophy?

Muscle vs motor neur

Open-uri20120721-23221-141oe0s
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 an dystrophy. It is a disease of motor neurons. It is an inherited recessive disease.

Difference between myalgia and muscular dystrophy?

Muscular Dystrophy

Muscular_dystrophy
Duchenne muscular dystrophy (DMD) is a genetic disorder characterized by progressive muscle degeneration and weakness. It is one of nine types of muscular dystrophy. DMD is caused by an absence of dystrophin, a protein that helps keep muscle cells intact. Symptom onset is in early childhood, usually between ages 3 and 5. Myalgia is a term to indicate muscle pain.
