This exercise targets your deltoids
, triceps, glutes, core, and latissimus dorsi, and is perfect for giving your butt, stomach and arms the toning they need.
The majority of reported SIRVA cases caused by overpenetration have occurred in individuals weighing <140 lb or those who had little deltoid
After bony fixation, all patients in the present study were found a negative stress test, which may be due to only patients with both a SMM fracture and a potential complete deltoid
ligament being included in the study.
One of the 13 patients in the 2010 case series by Atanasoff et al underwent arthroscopic shoulder repair during which the surgeons explored the deltoid
needle trajectory (as identified by the patient).
For example, when the deltoid
contracts to abduct the humerus, its line of pull would pull the head of the humerus straight up into the acromion (Figure 8A).
Interventions included LC on both the infraspinatus and posterior deltoid
muscles for the LC group, and passive cross-body stretch for the stretching group.
These exercises were chosen because they involve the deltoid
muscle and are commonly used in strength training programs.
It was horrifying to note in our study that 64.2% were not sure about the correct place of injection in the deltoid
muscle, 48.3% did not know the correct site for IMI in the gluteal muscle and an astounding 87.6% were injecting into the wrong muscle in the thigh, 26.9% of our test subjects stated that triceps can be used as a site for IMI which is not recommended as a very favored site for IMI in the literature because of fear of damage to the radial and profunda brachii artery which lie under the triceps muscle.
Abbreviations: AD = anterior deltoid
, BB = biceps brachii, EMG = electromyography, MD = middle deltoid
, ME = mechanical effectiveness, MVC = maximum voluntary isometric contraction, PC = principal component, PCA = principal component analysis, PD = posterior deltoid
, PM = pectoralis major, SCI = spinal cord injury, sEMG = surface electromyography, TB = triceps brachii, UT = upper trapezius.
When the deltoid
is revolved 360 degrees around a perpendicular Z axis while simultaneously twisting 120 degrees, the result becomes a single edge twisted doughnut-shaped solid called a deltoid
In RSR this increases the tension in the deltoid
muscle, which increases its functional strength while decreasing the mechanical torque at the glenoid.
According to current recommendations from the CDC's Advisory Committee on Immunization Practices and the American Academy of Pediatrics, the deltoid
muscle in the arm is the preferred site for intramuscular injections in children older than age 1 year, but those recommendations were based on data from 18-month-old children, and reflected an increased likelihood of discomfort and difficulty with movement of the extremity when thigh injections were used.
