    Electromyographic activity of the (A) vastus lateralis, (B) biceps femoris, (C) tibialis anterior, and (D) soleus muscles during assisted walking with the axillary crutch and ED Walker at 3 different weight-bearing loads. The black horizontal lines at 100% represent electromyographic activity required for normal walking. Abbreviation: EMG, electromyographic activity. ∗ED Walker greater than axillary crutch (P≤.05); †walking with assisted device significantly different from that of normal walking (P≤.05).

    Normalized peak vertical ground reaction force when subjects were instructed to self-select a light and heavy weight-bearing load while ambulating with the assistance of axillary crutches and the ED Walker. The black horizontal lines at 100% represent force recorded during normal walking. ∗ED Walker greater than axillary crutch (P≤.05); †walking with assisted device significantly different from that of normal walking (P≤.05).
