Fifty healthy subjects will execute a reaching movement in sitting. They will reach to a cone at a distance of little more than armlength.

Electromyogram (EMG) and kinematics will be the outcome measures. Secondary outcome measures are: sex, dexterity, skillfulness, Fifty first time stroke patients will execute the same movements. Primery outcome is EMG and kinematics; secundary outcome measures are: side of hemiplegia, arm recuperation.

Inclusion Criteria:

• BMI < 30
• no orthopedic, neurologic disorder that can influence the reaching
• age between 18 and 70 yrs

Exclusion Criteria:
