Lumbar spasm is a condition where in your back muscle is firmly contracting or moving involuntarily. This usually caused by various factors such as poor posture, muscle overuse, sprains and strains, etc.
A back brace can help reduce the symptoms by supporting the back and keeping the trunk in the ideal position to prevent further damaged.
