Chip on the Shoulder Origin The idiom “chip on the shoulder” originates from a 16th-century practice of challenging someone to a duel by placing a chip of wood on their shoulder. Today, it refers to a person who carries a grudge or feels inferior, leading them to act defensively or hostilely towards others. This sense…

Shoulder adhesive capsulitis MRI is a medical imaging technique that utilizes magnetic resonance imaging (MRI) to examine the shoulder joint for signs of adhesive capsulitis, a condition characterized by inflammation and thickening of the shoulder capsule, the tissue surrounding the joint. MRI provides detailed cross-sectional images of the shoulder, allowing physicians to assess the severity…

In the embrace of physical closeness, a woman’s curves and softness nestle against a man’s strong frame. The shoulder, a point of intimate contact, bears the gentle weight of her body as she is carried with warmth and support. Their intertwined arms create a haven of security, while their combined strength and endurance sustain the…

Taping for subluxed shoulder involves using adhesive tape to provide support and stability to the shoulder joint. The tape is applied in a specific pattern to help keep the shoulder in place and prevent further dislocation. This can be especially helpful in cases of recurrent subluxation or instability. Taping can also help to improve proprioception,…

A shoulder subluxation sling is a medical device designed to provide support and stabilization to the shoulder joint after a subluxation, which is a partial dislocation. It is typically made of a lightweight material and features adjustable straps that allow for a customized fit. The sling helps to keep the shoulder in place, reduce pain,…

Shoulder flexion goniometry is a valuable assessment tool used to evaluate the range of motion of the shoulder joint. It involves using a goniometer to measure the angle formed by the patient’s upper arm and forearm during the flexion movement. Proper understanding of anatomical structures, range of motion terms, and assessment protocols is essential for…

Shoulder muscle imbalance occurs when the various muscle groups surrounding the shoulder are not balanced in strength or flexibility. This can result from factors such as overuse, poor posture, or injury. Symptoms include pain, limited range of motion, and muscle tightness. Untreated imbalances can lead to poor posture, increased injury risk, and impaired daily activities….

Schiff-Sherrington posture is a classic example of how the nervous system uses proprioception to maintain balance. When standing, the body leans slightly forward, causing the head to move forward and the chest to move backward. This movement stimulates muscle spindles in the calf muscles, which send signals to the spinal cord. The spinal cord then…

Forward flexion of the shoulder involves bending the arm forward at the shoulder joint. The shoulder joint, formed by the articulation of the humerus, scapula, and clavicle, is stabilized by ligaments, tendons, and muscles, including the deltoids, pectoralis major, and rotator cuff. During forward flexion, the pectoralis major and anterior deltoid primarily contribute to this…

A shoulder arthrogram procedure involves injecting a contrast dye into the shoulder joint through an arthrogram needle. Fluoroscopy, a live X-ray imaging technique, is then used to guide the needle placement and monitor the dye distribution. The resulting images provide detailed visualization of the joint’s internal structures, including the labrum, cartilage, and ligaments, allowing for…

Multidirectional instability shoulder refers to a condition where the shoulder joint exhibits excessive mobility in multiple directions. This instability arises from compromised structures that normally provide stability, such as the glenoid labrum and inferior and superior glenohumeral ligaments. Contributing factors include joint laxity, muscle imbalances, and altered shoulder mechanics. The instability can manifest as recurrent…

The prime mover for shoulder abduction is the supraspinatus muscle. Situated in the scapular fossa, it originates at the supraspinous fossa and inserts at the greater tuberosity of the humerus. As an innervated part of the suprascapular nerve, it primarily contributes to arm abduction, allowing for the lifting of the arm away from the body…
