Table 4 EMG median frequencies

From: Muscle activation patterns during walking from transtibial amputees recorded within the residual limb-prosthetic interface

  Maximum voluntary activation Treadmill walking (1.0 m/s)
Controls mean (sd) Amputees mean (sd) Controls mean (sd) Amputees mean (sd)
Tibialis Anterior 153 (14) *° 127 (23) * 115 (22) ° 121 (18)
Gastrocnemius Medial Head 174 (23) *° 137 (26) * 131 (18) ° 124 (49)
Gastrocnemius Lateral Head 166 (23) *° 124 (34) * 122 (14) ° 119 (40)
Vastus Lateralis    97 (24) 88 (17)
Rectus Femoris    156 (62) 123 (42)
Biceps Femoris    113 (18) 101 (15)
Gluteus Medius    102 (18) 109 (30)
  1. *p < 0.001 for controls vs. amputees; °p < 0.001 for maximum voluntary activation vs. treadmill walking.
