Results of the EMG analysis For the floor walking condition, the pattern of the thigh muscles (Mm. vastus medialis, lateralis, glutues medius)
was comparable during the real and simulated conditions across all subjects. Minimal deviations were a delayed onset and a prolongation of the activation of the Mm. vastus medialis, lateralis during the simulated walking (p < 0.05). Instead of the vastus medialis muscle, two subjects more activated the vastus lateralis on the machine (Figure 4). For the shank muscles, deviations became apparent for two subjects. The tibialis anterior muscleremained rather silent during the real and the simulated floor walking, whereas the activity of the gastrocnemius muscle showed a tonic activation pattern during the real and a phasic, but less intense, activation pattern during the simulated walking on the floor (Figure 5). For the remaining four subjects no clear differences became apparent. Table 1 resumes the relevant data of the activation patterns of the shank and thigh muscles for both floor walking conditions
