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.
What is the Social Security Retirement Age? Social Security's full-benefit retirement age is increasing gradually because of legislation passed by Congress in 1983. Traditionally, the full benefit age was 65, and early retirement benefits were first available at age 62, with a permanent reduction to 80 percent of the full benefit amount. Currently, the full benefit age is 66 for people born in 1943-1954, and it will gradually rise to 67 for those born in 1960 or later.
