What treatment using specialized soft-tissue manipulation is often used for patients with fibromyalgia?

The treatment using specialized soft-tissue manipulation that is often used for patients with fibromyalgia is myofascial release. Fibromyalgia is a chronic condition characterized by widespread musculoskeletal pain, fatigue, and tenderness in localized areas. Myofascial release is a hands-on technique that involves applying gentle sustained pressure to the myofascial connective tissue to alleviate pain and improve mobility. It aims to release tension and tightness in the fascia, which is the connective tissue that surrounds and supports muscles, bones, and organs.

Tenolysis is a surgical procedure that involves the release of adhesions around a tendon. It is not typically used as a treatment for fibromyalgia.

Fasciotomy is a surgical procedure that involves the incision and release of the fascia to relieve pressure and tension. It is commonly used to treat conditions such as compartment syndrome, but it is not a primary treatment for fibromyalgia.

Myotomy is a surgical procedure that involves the incision or division of a muscle. It is not a treatment commonly used for fibromyalgia.

Therefore, the correct answer is B. myofascial release, as it is the specialized soft-tissue manipulation technique often used for patients with fibromyalgia.
