Utilizing the modified scale of 0–12, with 12 indicating full strength, it is notable that full strength was not found for any of the selected movements in children or adults with GSD IIIa. As noted in Table 3, a score of 7 (red line) indicates the movement is completed in full range against gravity, but the muscle group is unable to tolerate any additional resistance. A score of 10 (green line) indicates the muscle group can tolerate moderate, but not full, resistance.
