Supraspinatus | ARM MOVERS

Supraspinatus | ARM MOVERS | Rotator Cuff

The supraspinatus (plural supraspinati) is a relatively small muscle of the upper back.
Supraspinatus,Infraspinatus, Subscapularis and Teres Minor together This Four Muscle work as rotatory to the Humerus. so also known as Rotator Cuff.

Supraspinatus ORIGIN:

Supraspinatus originates from supraspinous fossa of the scapula.

Supraspinatus INSERTION:

Supraspinatus is inserted at the superior part of greater tubercle of the humerus.

Supraspinatus ACTION:

Supraspinatus stabilizes the shoulder joint.
Supraspinatus helps prevent downward dislocation of the humerus.

Supraspinatus NERVE SUPPLY:

Supraspinatus is innervated by Suprascapular nerve.

What is Anatomical pulley? Example of Anatomical pulley

Understanding the Importance of Anatomical Pulleys in Physiotherapy As a physiotherapy student, it is essential to have a good understanding of the human body's anatomy and how it works. One of the essential structures in the body that plays a significant role in movement and biomechanics is the anatomical pulley. In this article, we will explore what an anatomical pulley is, its types, and its importance in physiotherapy. What is an Anatomical Pulley? A pulley is a simple mechanical machine that consists of a wheel that turns readily on the axle, usually grooved for a rope or a wire cable. In the human body, the pulley is replaced by a bone, cartilage, or ligament, and the cord is replaced by a muscle tendon. The tendon is lubricated by synovial fluid, and the surface of the tendon is covered by a thin visceral synovial membrane. The tendon is lubricated so that it may easily slide over the pulley. Classification of Anatomical Pulleys There are mainly four classes of pulleys ...

Electrotherapy Simplified by Basanta Kumar Nanda PDF Download

Electrotherapy Simplified by Basanta Kumar Nanda The aim of this book is to focus on the electrotherapy simplified. Electrotherapy is one of the important aspects among the various approaches of patient management available to a physiotherapist. Electrotherapy Simplified has tried to give comprehensive knowledge on electrotherapy and actinotherapy, starting from basic electricity and magnetism to the theoretical and clinical aspects of the different modalities applied by physiotherapists. This book consists of 19 chapters, which include an introduction, inflammation, repair, and role of physical agents, electrical fundamentals, magnetic energy, valves, transistors, and rectifiers, electrical measurement systems and distribution of electricity, electrophysiology of nerve transmission, and muscle contraction, low-frequency currents, electrodiagnosis, medium frequency currents, low-intensity laser therapy, ultraviolet radiation, and traction. About 250 objective question ...

Range of Muscle work in Physiotherapy

The degree of the movement done by muscle contraction is known as the Range of muscle work. The range can be measured with the help of a goniometer. Movement is a very complex mechanism, a lot of muscles are working in a group and in synchronized pattern to draw out the perfect desirable movement. As per function we already talked about Agonist, antagonist, Synergist, and fixator muscles.
