Abstract: The effect of physical exercise performed on a physical function of a subject with an irreversibly reduced physical function is promoted. Bone marrow mononuclear cells, CD34-positive cells, CD133-positive cells, or stem cells are contained. The central and peripheral nerves communicate intimately with each other. When these cells are administered to a subject, and the subject performs an appropriate physical exercise, the reduced physical function can be dramatically improved. The physical exercise .is, for example, physical exercise that stimulates both of brain and peripheral nerves based on the interactive biofeedback theory. Thus, for example, when bone marrow mononuclear cells are administered to a patient with a sequela of cerebral infarction, and the patient performs an appropriate physical exercise, the effect of functional recovery from the sequela of the cerebral infarction is promoted.
