The most effective type of massage therapy for lower back pain is neuromuscular therapy. Neuromuscular therapy is also called trigger point myotherapy. The American Academy of Pain Management recognizes this form of massage therapy as an effective treatment for back pain caused by soft tissue injury (such as a muscle strain).
Neuromuscular massage therapy technique

Neuromuscular therapy consists of alternating levels of concentrated pressure on the areas of muscle spasm. The massage therapy pressure is usually applied with the fingers, knuckles, or elbow. Once applied to a muscle spasm, the pressure should not vary for ten to thirty seconds.
