Bimanual coordination deficits in hands following stroke and their relationship with motor and functional performance

Table 3 Comparison of the coefficient of variation (CV) of alternating time and force applied for bimanual grip force coordination control during two conditions among the healthy and stroke groups

Outcome	Condition	Healthy group (n = 16)		Stroke group (n = 22)		Between group
Outcome	Condition	Mean	SD	Mean	SD	t	Sig. (2-tailed)
Alternating time	Condition 1	34.6%	14.5%	30.9%	16.0%	0.735	0.467
Alternating time	Condition 2	15.3%	10.3%	31.5%	16.3%	−3.500	0.001*
Force applied	Condition 1	26.6%	13.6%	32.4%	18.8%	−1.042	0.305
Force applied	Condition 2	14.0%	6.1%	31.2%	19.4%	−3.417	0.002*

Note: Condition 1 was transfer from the non-dominant to the dominant hand in a healthy subject or from the paretic to the non-paretic hand in a stroke patient; Condition 2 was transfer from the dominant to the non-dominant hand in a healthy subject or from the non-paretic to the paretic hand in a stroke patient
