Upper Limb Prosthetics: Harness Systems and Amputation Levels
Prosthetic Harness Systems: Control and Function
A **harness system** is a critical component of body-powered prostheses, particularly for upper limb amputees. It enables users to control their prosthetic device through movements of their shoulders, residual limb, or other body parts.
Components of a Harness System
- ***Harness***: A flexible or rigid framework that fits around the user’s body, typically the shoulders, chest, or residual limb.
- ***Cables***: Connect the harness to the prosthetic device,
Amputee Rehabilitation: Stump Shaping, Prosthetics, and Mobility Training
Post-Amputation Care and Rehabilitation
The proper management of the residual limb (stump) following amputation is a critical component of post-operative care. Meticulous bandaging, combined with the appropriate use of prosthetics and orthotics, supports healing, controls swelling, and prepares the limb for functional independence.
Foundational Role of Stump Bandaging
Stump bandaging is not merely a wound care measure; it plays a foundational role in prosthetic success. It helps control edema, shape

Oral Hypoglycemic Agents (OHAs)
Oral Hypoglycemic Agents (OHAs) are medications taken by mouth to help lower blood sugar levels in people with type 2 diabetes. They work by stimulating the pancreas to produce more insulin, improving the body’s sensitivity to insulin, or slowing down the absorption of glucose from the digestive tract.
Types of Oral Hypoglycemic Agents
Sulfonylureas
These stimulate the pancreas to release more insulin (e.g., glipizide, glyburide).
Meglitinides
Similar to sulfonylureas,

What is a Permanent Risk Factor?
A permanent risk factor is defined as any condition hazardous to the health of the worker.
What is a Pollutant?
A pollutant is an energy, a chemical, or a living being that can cause harmful effects on human health when present in sufficient concentration.
Routes of Entry for Pollutants into the Body
- Respiratory
- Digestive
- Dermal (Skin)
- Parenteral (Injection or wound)
Effects of Pollutants on the Human Body
Pollutants can have

Rehabilitation Measures After Neurosurgical Operations
Rehabilitative measures following a neurosurgical operation are critical for promoting recovery, maximizing function, and improving the patient’s quality of life. The specific type and intensity of rehabilitation depend heavily on the nature of the surgery (e.g., tumor removal, trauma, aneurysm repair, or epilepsy surgery), the area of the brain involved, and the patient’s overall health status.
Goals of Post-Neurosurgical Rehabilitation

Hand Orthotics: Anatomy, Splint Types, and Patient Training Protocols
Functional Anatomy of the Hand and Orthotics
Hand orthotics, also known as hand splints or braces, are externally applied devices designed to support, align, correct deformities, or improve the function of the hand. Understanding their function requires examining the anatomical structures they aim to support or manipulate.
Skeletal Structure and Joints
The hand is a complex structure composed of 27 bones, including the carpals, metacarpals, and phalanges, arranged to allow precise and diverse movements.
