Hvordan påvirkes muskelaktiviteten ved bruk av ankelortose i tidlig fase etter hjerneslag?
Sammanfattning
Intention: To develop knowledge on how emg. activity in musculus tibialis anterior is affected in
swing phases during walking when using ankle foot orthosis.
Design: Causal experimental.
Participants: Nine stroke survivors and five healthy subjects.
Methods: Emg. of m.tibialis anterior on the paretic side was measured. Foot-switches were attached
to the heels to record the transitions between swing- and stand phases. In addition, the test persons
answered a simple questionnaire, registering the test subjects’ experiences during walking.
Results and conclusion: Group: Walking with orthosis showed small, but insignificant, reduction in
emg. activity in the stroke survivors, as well as for healthy subjects walking with their preferred
speed. Increased variability in emg.-responses were present in stroke survivors, especially when
walking without orthosis.
Individuals: The emg. activity showed large differences between stroke survivors. Emg. activity was
significantly reduced in 4 of 9 stroke survivors when walking with orthosis.
