Causes. Leg length discrepancies can be caused by poor alignment of the pelvis or simply because one leg is structurally longer than the other. Regardless of the reason, your body wants to be symmetrical and will do its best to compensate for the length difference.
Date of Onset. When the Social Security Administration (SSA) refers to a disability applicant's Date of Onset, they are referring to the date that a Social Security Disability applicant became disabled. When you fill out your Social Security Disability claim forms, you will be asked to provide the date your disability began.
(For some claims that go through the appeal process to a hearing in front of an administrative law judge, it can take one to two years to get a disability decision.) However, your onset date for payment purposes can only be 17 months before your application dateâthat's because Social Security allows a maximum of 12 months of retroactive benefits.
