There are many reasons your legs will appear to be different lengths. Depending on the reasons for the difference will determine whether you should do anything about it or not.
Structural differences are due to congenital, post-surgical or traumatic reasons that the skeleton is physically different right to left. Anything less than ¼ is considered within normal and intervention is necessary only if there is discomfort associated with the difference. Using lifts for this type of difference is usually very successful if the body have good range of motion in the pelvis and lower back.
Functional differences are much more common and are often due to postural or muscular problems. The spine and pelvis can not stay straight because the posture and muscles hold the spine in a curved position. Often, functional differences are best treated with physiotherapy, chiropractic care or postural re-training. Using lifts or inserts must be closely monitored and are treated very conservatively.If you have any questions about lifts, talk to your doctor, then talk to us!
