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.
Most people think of Social Security as a retirement program, but disability benefits are also a huge part of Social Security. About 8.8 million Americans receive Social Security disability benefits, and another 1.8 million more dependents rely on the program to help make ends meet. One of the most confusing things about Social Security disability is what happens after you reach retirement age. For many disabled Americans, shortened work histories mean that retirement benefits would ordinarily be unavailable or insufficient to meet their financial needs.
