Electromyographic data of this study demonstrate that gluteus medius and tensor fascia latae, who behaved in a similar way considering muscle activation, showed significant difference at time IR between the evaluated sessions for DG and HG, and at time FR for DG.
With the difference in muscle activation at time IR between the evaluated sessions, it was verified an increase in stimulation with 10 hippotherapy sessions, regardless of whether they were conducted once or twice a week, which was significant for the muscles gluteus medius, tensor fascia latae, rectus femoris and gastrocnemius in DG, and gluteus medius and tensor fascia latae in HG.
During the midstance phase of the gait cycle, contraction of the tensor fascia latae
and gluteus maximus muscles create a compressive force that is transmitted through the length of the entire femur that prevents it from bending with the application of ground-reactive forces during midstance.
The bursa at the greater trochanter comes between the bone and a small muscle known as the tensor fascia latae
Other common causes of trochanteric bursitis include osteoarthritis of the hip or lumbosacral spine, scoliosis, or a pathologically tight tensor fascia latae
caused by running.
During SHA, the tensor fascia latae electrodes were placed at the mid-point of an imaginary line between the greater trochanter and the anterior superior iliac spine (ASIS).
When asymptomatic individuals performed SHA, the gluteus medius and tensor fascia latae were clinically observed to become active prior to the ipsilateral erector spinae, with the GM firing first (Greenman, 2003).
The left iliotibial band (ITB), tensor fascia latae
(TFL), and gluteus medius were short compared to the right.
Tightness in the iliotibial band and weakness in the gluteusmedius cause compression of the bursa between the tensor fascia latae
and the greater trochanter.
Palpable tissue tension was discovered in the complex of the tensor fascia latae, iliotibial band, lateral aspect of gluteus maximus, as well as the fascia latae along the lateral aspect of the right femur.
12) The structure originates proximally from the iliac crest; it is then joined by the collective fascia of the gluteus maximus posteriorly, the tensor fascia latae anteriorly, and indirectly from the fascia of the gluteus medius (see figure 3).
The tensor fascia latae
and the iliotibial tract are located on the lateral thigh and they medially rotate and abduct the hip.
