Outcome measures
Primary outcome
* Movement time (seconds) during single and dual movements in different
conditions.
* Precision (distance in centimetres with respect to the centre of the target)
during single and dual conditions.
* Movement rate (coefficient of temporal variation between events, %) during
repetitive single and dual task conditions.
* Number of digits in a series recalled during single cognitive and dual task
conditions.
Secondary outcome
Muscle activation patterns (timing and peak activity) as measured with surface
EMG at the affected arm and hand (m. Deltoideus, m. Biceps en m. Triceps)
during the tasks.
Movement excursion (in degrees) of the thorax, shoulder, elbow, wrist during
the functional movement
Background summary
Dual tasks are affected after a stroke. They have been widely investigated in
gait, however research about dual tasks in activities involving the upper limb
is scarce. Upper limb impairments have a great impact in activities of daily
living and some of them need dual tasking. In a previous study, we have shown
that people who have had a stroke and have upper limb impairments, showed
cognitive motor-interferences during repetitive dual tasks with arm support.
Interestingly, we saw that the cognitive task served as a strategy to pace
movements. Since arm support and cueing during repetitive movement have
demonstrated to be effective to decrease attentional demands and increase
automaticity of movements, respectively, it would be interesting to know the
magnitude of cognitive-interferences during dual tasks taking into account
those variables.
Study objective
To determine the magnitude of the cognitive-motor interference during a
repetitive dual tapping task with arm support comparing with a single
condition, without arm support and with a non-repetitive dual task. Also, to
explore how segment kinematics changes in a single or a dual task compared with
a similar functional movement in people who have suffered a stroke.
Study design
Exploratorive cross-sectional study with one measurement session
Intervention
De tapping tasks will be performed with and without receiving gravity support
from an arm support system
Study burden and risks
The burden and risk associated with participation is low, as participants are
asked to perform movements that are likely to occur during daily life. Periods
of rest can be taken during the measurement in case of fatigue. Participants
will not benefit from participation,
