UPPER GLUTEUS MAXIMUS, GLUTEUS MEDIUS, TFL
– Side Lying with Hip Flexed @45º and Knee Flexed @90º
Which Exercises Target the Gluteal Muscles While Minimizing Activation of the Tensor Fascia Lata? – 2013
Procedure
– determine which exercises are best for activating the gluteus medius and the superior portion of the gluteus maximus, while minimizing activity of the tensor fascia lata (TFL).
Fine Wire Electrodes
– SUP-GMAX: superior and lateral to midpoint of a line drawn b/n the posterior superior iliac spine and posterior greater trochanter.
– GMED: inserted 2.5 cm distal to the midpoint of the iliac crest (ie, middle portion).
– TFL: inserted distal and slightly lateral to the anterior superior iliac spine and medial and superior to the greater trochanter.
| Hip abduction in side lying | Starting position was lying on a treatment table, on the side opposite the tested limb. The table was placed along a wall. The lower extremity on the table was flexed to 45° at the hip and 90° at the knee. The subject’s back and plantar foot were against the wall for control of position and movement. The subject then abducted the tested hip to approximately 30° and then returned the limb to the table. To control for the correct movement, the subject kept the heel in light contact with the wall (via a towel) while sliding it along the wall, with the toes pointed horizontally away from the wall. |
