| Cardiac Disorders | Limitation of out-door activities | (Notes) 1. In case a person has two impairments listed in the same grade, his grade is to be one grade severer, except that two impairments are specifically described as double 2. In the categories of upper and lower limb, the person who has two impairments in grade 7 is considered as grade 6. 3. In case a person has two impairments in different grades, his grade is to be decided. 4. “Amputation of finger” means amputation above IP joint of thumb, and above PIP joint of other fingers. 5. “Function loss of finger” means the impairment below MP joint, and in case of thumb, opponent motion is included. 6. The length of amputated stump is the practical length measured from underarm in upper limb, and from sciatic tuberous in lower limb.
7. The length of lower limb is to be measured from spine iliaca anterior superior to medical maleolus. |
