Joanne Macza designed and invented the s•weggy specifically to create more mobilization of the sacrum in order to unload joint and soft tissue restrictions of the sacrum and its surrounding joints such as the ilium, lumbar spine and hip. This tool also allows the sacrum to be placed in a neutral position relative to the lumbar spine in order to optimize and train spine, pelvis and hip muscle activation and stabilization which then allows maximum long term benefits with sitting, standing, walking and higher level gym activities of varying degrees as well as providing symptom relief.
