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

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

Outcome Condition Healthy group (n = 16) Stroke group (n = 22) Between group
Mean SD Mean SD t Sig. (2-tailed)
Alternating time Condition 1 34.6% 14.5% 30.9% 16.0% 0.735 0.467
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
Condition 2 14.0% 6.1% 31.2% 19.4% −3.417 0.002*
  1. 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
  2. * Significant difference p < 0.05
