Hypoglossal nerve palsy or paralysis is an occasional but clinically serious disorder that results from affecting the hypoglossal nerve (cranial nerve XII). The tongue’s intrinsic and extrinsic muscles, which are mostly supplied by this nerve, are essential for speaking, swallowing, and keeping the airway’s purity. These abilities can be severely impaired by damage to the hypoglossal nerve….
Sural neuritis, also known as sural neuralgia, is a painful disorder caused by irritation or damage to the sural nerve. The most common description of the pain is a burning feeling on the outside of the foot and ankle. It can happen after surgery on the feet and ankles or if there is a nerve injury. Using an…
Introduction Of Abnormal Posturing: Definition of Abnormal Posturing Abnormal posturing refers to involuntary and rigid body movements or positions that are often indicative of severe brain injury or neurological disorders. These postures result from disrupted communication between the brain and the muscles, typically due to damage in the central nervous system. There are mainly two…
An obturator nerve injury is damage to the obturator nerve, which originates in the lower back from the lumbar plexus. In the groin is where the obturator nerve is situated. Through the pelvis and into the inner thigh, the obturator nerve provides motor function and sensation to the muscles that aid adducting (bringing the legs together). This…
Our walking pattern is referred to as our gait. Our bodies are normally upright, not falling forward or backward, with arms swinging to the sides and an even stride. Our center of gravity is stabilized when we stand up straight, which helps us to keep our balance. A Parkinsonian gait: what is it? Parkinsonian gait…
Radiculopathy is caused by the compression or irritation of a nerve root located in the spinal column. In the case of “Thoracic Radiculopathy,” the symptoms are caused by a disease process that occurs within the thoracic spine. What is a Thoracic Radiculopathy? Thoracic radiculopathy refers to a condition where the nerve roots in the thoracic (mid-back) region…
Spinal Accessory Nerve Palsy, also known as Accessory Nerve Palsy, is a neurological condition characterized by the dysfunction of the spinal accessory nerve (cranial nerve XI). This nerve is primarily responsible for innervating the sternocleidomastoid and trapezius muscles, which are essential for head rotation, shoulder elevation, and certain movements of the neck and scapula. Damage…
Glossopharyngeal neuralgia (GPN) is an uncommon disorder that can produce shooting, stabbing, or intense pain in the back of the tongue, the tonsils, or the middle ear. The path that the discomfort follows is the glossopharyngeal nerve, which runs deep in the neck. It supports the eustachian tube, middle ear, parotid gland (one of the salivary…
What is Rigidity? Rigidity refers to a condition characterized by an increased resistance to passive movement, which remains constant regardless of the position or velocity of the movement. This type of muscular hypertonia is distinct from other forms of muscle stiffness, such as spasticity, where resistance varies with the speed of motion. Many authors use…
Lumbar radiculopathy refers to a condition where the spinal nerve roots in the lower back, specifically the lumbar region, are compressed or irritated. This compression can result from various factors, such as herniated discs, bone spurs, degenerative disc disease, or spinal stenosis. Definition The condition known as lumbar radiculopathy is an inflammation of a nerve root in…
