The pulse amplitude for implanted stimulation channels to the quadriceps and erector spinae
was 2 mA, which was sufficient to produce the knee and trunk extension required to stand erect without discomfort.
Muscles Target: quadriceps Synergists gluteus maximus, adductor magnus soleus; Dynamic Stabilizers: hamstrings, gastrocnemius; Stabilizers: erector spinae
, gluteus medius, gluteus minimus Type: Front squat Dumbbells Instructions Stand with dumbbells grasped to sides.
Back extension: Working the erector spinae
muscles of the lower back.
They postulated that this might be because of the contribution of a wide range of muscles including abdominal, psoas, posterior hip group, and erector spinae
and the larger excursion during lumbar flexion which challenges muscles more.
Cervical postural muscle load was measured using EMG of the bilateral cervical erector spinae
and upper trapezii since they are the major stabilizing muscles of the cervical spine (Szeto et al 2005a to d).
These muscles are joined by the following superficial muscles that play a key role in core strength - Rectus Abdominus, Erector Spinae
and External Oblique.
EMG was analyzed on the rectus abdominus, external obliques, latissimus dorsi and erector spinae
. Ultrasound was assessed on these same muscles plus the transverse abdominus.
The core encompasses the abdominal, oblique, erector spinae
and latissimus dorsi muscles (front, sides and back of your trunk).
The gluteal muscles, the quadriceps, calves, anterior deltoids of the shoulders, and erector spinae
are the most important drive phase muscles for acceleration.
Low back - the erector spinae
muscles extend the back and aid in good posture..
The trapezius, latissimus dorsi, rhomboids and erector spinae
are often forgotten about as a way of increasing our metabolism.
(1,2) Injury typically occurs at either the superior lumbar (Grynfeltt-Lesshaft) triangle, which is bordered by the 12th rib superiorly, erector spinae
muscle posteriorly, and internal oblique muscle anteriorly; or the inferior lumbar (Petit's) triangle, which is bordered by the iliac crest inferiorly, external oblique muscle anteriorly, and latissimus dorsi muscle posteriorly.3 However, the injury may occur at other locations.
