Back cracking for cramps? study tests spinal therapy for period pain

This study looked at whether spinal manipulation combined with connective tissue massage can reduce pain, menstrual symptoms, depression, and sleep problems in women with primary dysmenorrhea (painful periods). Seventy-five women were split into three groups: one received both treatments, one got massage with a fake spinal manipulation, and one had no treatment. Over six weeks, researchers measured pain, symptoms, mood, and sleep quality to see if the combo approach helps.
