Table 1 Placement of electrodes for quadriceps, hamstring and gastrocnemius muscle

From: Muscle activation patterns around knee following neuromuscular training in patients with knee osteoarthritis: secondary analysis of a randomized clinical trial

Muscles

Placement of electrodes

Biceps femoris (LH)

35% of the distance from the ischial tuberosity to the lateral side of the popliteus cavity, starting from the ischial tuberosity.

Semitendinosus (MH)

36% of the distance from the ischial tuberosity to the medial side of the popliteus cavity, starting from the ischial tuberosity

Vastus lateralis (LQ)

94 mm of the distance (mm) along a line from the superior lateral side of the patella to the anterior superior iliac spine, starting from the patella.

Vastus medialis (MQ)

52 mm of the distance from superior medial side of the patella along a line medially oriented at an angle of 50 degree with respect to the anterior superior iliac spine.

Gastrocnemius medialis (MG)

50% of the distance from the medial side of the popliteus cavity to the medial side of the achilles tendon insertion, starting from the achilles tendon.

Gastrocnemius lateralis (LG)

60% of the distance from the lateral side of the popliteus cavity to the lateral side of the Achilles tendon insertion, starting from the achilles tendon

  1. LH lateral hamstring, MH medial hamstring, LQ lateral quadriceps, MQ medial quadriceps, MG medial gastrocnemius, LG lateral gastrocnemius
