Muscles that Move the Arm
0 Views •

Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles. The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

We developed a real-time mirror robot system for functional recovery of hemiplegic arms using automatic control technology, conducted a clinical study on healthy subjects, and determined tasks through feedback from rehabilitation doctors. This simple mirror robot can be applied effectively to occupational therapy in stroke patients with a hemiplegic arm.

Excess Pressure Inside a Drop and a Bubble

The shape of a small drop of liquid can be considered spherical, neglecting the effect of gravity. This drop can further be considered as two equal hemispherical drops put together due to surface tension. The forces acting on the spherical drop are due to the pressure of the liquid inside the drop, the pressure due to air outside the drop, and the force due to the surface tension acting on the two hemispherical drops. where γ corresponds to the surface tension. Recalling that the force per...

The eight-arm radial water maze is designed to evaluate reference and working memory performance simultaneously by requiring subjects to use extra-maze cues to locate escape platforms and remedies the limitations observed in land based radial arm maze designs.
FAQs
The key challenge is controlled lowering after the arm has been abducted, meaning moved away from the body. This movement requires the patient to maintain strength and control rather than simply hold the arm in position. Difficulty controlling the descent can therefore suggest impaired rotator cuff function, particularly involving the supraspinatus tendon, although it does not establish the exact structural problem.
A sudden drop suggests that the patient cannot control the arm’s descent, while marked pain may also interfere with performance. Either finding can be consistent with rotator cuff dysfunction, including possible supraspinatus tendon injury. These responses should be interpreted as clinical clues rather than proof of a tear, because the test alone cannot confirm structural damage.
Shoulder history provides context for the reported pain and functional problem, while range-of-motion assessment and additional strength tests add information about overall shoulder performance. Considering these findings together helps clinicians judge whether the response is consistent with suspected rotator cuff dysfunction. The combined examination also helps determine whether further evaluation, such as imaging, may be appropriate.
The examiner first abducts the patient’s arm and then asks the patient to lower it slowly and smoothly. During the descent, the examiner observes whether the patient maintains control, experiences significant pain, or allows the arm to drop suddenly. The maneuver is then considered alongside the rest of the shoulder examination rather than interpreted in isolation.
Clinicians may use the maneuver when shoulder pain raises concern for rotator cuff dysfunction, particularly possible supraspinatus tendon involvement. Its main value is as part of a focused physical examination that assesses controlled arm movement and strength. The result can guide the next stage of evaluation, but it cannot independently confirm the presence or extent of injury.
An abnormal response may warrant additional clinical examination and, when structural injury remains a concern, imaging. The test can identify findings that support further assessment, such as weakness, sudden loss of control, or significant pain during lowering. Imaging and other examination results are needed to help confirm whether a rotator cuff tear or another structural problem is present.
