Is multidimensional motor sequence learning impaired in older but not younger or middle-aged adults?
Our data suggest that, when younger and middle-aged adults practice sequences containing multiple dimensions of movement, the motor element is most important for motor learning. The absence of sequence-specific change demonstrated by an older adult group that was healthy suggests an age-related impairment in motor learning that may have profound implications for rehabilitation.
W-d HCCs were clinically demonstrated not to be early cancer, because there was no significant difference in disease free survival between the patients with w-d and l-d HCCs.
