Background
The
impact of hand dominance on the expected (motor and functional ability
and daily use) improvement of the affected upper extremity (UE) in
subacute stroke has not yet been investigated.
Objectives
To
compare between the affected dominant and affected nondominant UE (1)
on rehabilitation admission (T1) for motor and sensory abilities,
functional ability, and daily use and (2) 6 weeks poststroke onset (T2)
and the UE recovery between T1 and T2 regarding percent change,
improvement effect size, and percent of participants achieving minimal
clinical important difference (MCID).
Methods
Multicenter longitudinal study.
Results
Thirty-eight
participants with affected dominant and 51 participants with affected
nondominant UE were recruited. On T1 and T2, between-group differences
were not seen for all UE variables. Significant improvement in the motor
and functional ability, daily use, and perceived recovery between T1
and T2 were seen for the affected dominant (z = −3.01 to −4.13, P < .01) and nondominant UEs (z = −4.59 to −5.32, P
< .01). Effect size improvement values were moderate and large in
the affected dominant and nondominant UE (respectively). In addition,
14% to 40% of the participants in both UEs achieved MCID.
Conclusions
Significant
and similar clinical meaningfulness in UE improvement can be expected
during subacute rehabilitation; however, improvement magnitude and
percent improvement is different for the UE domains of the affected
dominant and the affected nondominant UEs. These findings highlight the
distinct roles of the dominant and nondominant hands during bimanual
daily activities, which can guide clinicians during stroke
rehabilitation.
