Figure 1From: Quadriceps arthrogenic muscle inhibition: the effects of experimental knee joint effusion on motor cortex excitabilityDiagram illustrating the study protocol. Maximum effort voluntary contractions (MVC) of the quadriceps were performed prior to the first measurements of the dependent variables. After a 5-minute rest period, transcranial magnetic stimulation was used to measure the dependent variables at baseline 1 (B1), 10Â minutes later at baseline 2 (B2) and then immediately after experimental knee joint infusion (P1). At each measurement interval the dependent variables were measured with the quadriceps at rest (resting condition) and then during a quadriceps contraction at 10% of maximum voluntary contraction (active condition).Back to article page
