Low-level Laser Therapy
Low-level laser therapy (LLLT), cold laser therapy or photobiomodulation (PBM) is a medical treatment approach that applies low-level (low-power) lasers or light-emitting diodes (LEDs) to the surface of the body. Whereas high-power lasers are used in laser medicine to cut or destroy tissue, it is claimed that application of low-power lasers stimulates healing, relieves pain, and enhances cell function. Described sometimes as Low-level Red-light Therapy (LLRL), has effects that appear to be limited to a specified set of wavelengths. The effectiveness of red light therapy for treating various conditions is still under investigation. Repeated low level red light therapy may be effective for controlling myopia in children. Several such devices are cleared by the United States Food and Drug Administration (FDA), and low level red light therapy is being tested for treating a range of medical problems including rheumatoid arthritis and oral mucositis.

Power (physics)
Power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. Power is a Scalar (physics), scalar quantity. Specifying power in particular systems may require attention to other quantities; for example, the power involved in moving a ground vehicle is the product of the aerodynamic drag plus traction (engineering), traction force on the wheels, and the velocity of the vehicle. The output power of a Engine, motor is the product of the torque that the motor generates and the angular velocity of its output shaft. Likewise, the power dissipated in an electrical element of a electrical circuit, circuit is the product of the electric current, current flowing through the element and of the voltage across the element. Definition Power is the Rate (mathematics), rate with respect to time at which work is done or, more generally, the rate of change of total mechanical energy. It is ...

Wound Healing
Wound healing refers to a living organism's replacement of destroyed or damaged tissue by newly produced tissue. In undamaged skin, the epidermis (surface, epithelial layer) and dermis (deeper, connective layer) form a protective barrier against the external environment. When the barrier is broken, a regulated sequence of biochemical events is set into motion to repair the damage. This process is divided into predictable phases: blood clotting (hemostasis), inflammation, tissue growth ( cell proliferation), and tissue remodeling (maturation and cell differentiation). Blood clotting may be considered to be part of the inflammation stage instead of a separate stage. The wound-healing process is not only complex but fragile, and it is susceptible to interruption or failure leading to the formation of non-healing chronic wounds. Factors that contribute to non-healing chronic wounds are diabetes, venous or arterial disease, infection, and metabolic deficiencies of old age.Enoch, ...

Smallpox
Smallpox was an infectious disease caused by Variola virus (often called Smallpox virus), which belongs to the genus '' Orthopoxvirus''. The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, making smallpox the only human disease to have been eradicated to date. The initial symptoms of the disease included fever and vomiting. This was followed by formation of ulcers in the mouth and a skin rash. Over a number of days, the skin rash turned into the characteristic fluid-filled blisters with a dent in the center. The bumps then scabbed over and fell off, leaving scars. The disease was transmitted from one person to another primarily through prolonged face-to-face contact with an infected person or rarely via contaminated objects. Prevention was achieved mainly through the smallpox vaccine. Once the disease had developed, certain antiviral medications could poten ...

Light Therapy
Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, neonatal jaundice, and skin wound infections. Treating skin conditions such as neurodermatitis, psoriasis, acne vulgaris, and eczema with ultraviolet light is called ultraviolet light therapy. Medical uses Nutrient deficiency Vitamin D deficiency Exposure to UV-B light at wavelengths of 290-300 nanometers enables the body to produce vitamin D3 to treat vitamin D3 deficiency. Skin conditions Light therapy treatments for the skin usually involve exposure to ultraviolet light. The exposures can be to a small area of the skin or over the whole body surface, as in a tanning bed. The most common treatment is with narrowband UVB, which has a wavelength of approximately 311–313 nan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niels Ryberg Finsen
Niels Ryberg Finsen (15 December 1860 – 24 September 1904) was a physician and scientist. In 1903, he was awarded the Nobel Prize in Medicine and Physiology "in recognition of his contribution to the treatment of diseases, especially lupus vulgaris, with concentrated light radiation, whereby he has opened a new avenue for medical science." Biography Niels Finsen was born in Tórshavn, Faroe Islands, as the second-oldest of four children. His father was , who belonged to an Icelandic family with traditions reaching back to the 10th century, and his mother was Johanne Formann from Falster, Denmark. The family moved to Tórshavn from Iceland in 1858 when his father was given the position of Landfoged. When Niels was four years old his mother died, and his father married her cousin Birgitte Kirstine Formann, with whom he had six children. In 1871 his father was made ''Amtmand'' of the Faroe Islands. His father was a member of the Faroese parliament for 12 years, and his older b ...

Faroe Islanders
Faroese people or Faroe Islanders (; ) are an ethnic group native to the Faroe Islands. The Faroese are of mixed Norse and Gaelic origins. About 21,000 Faroese live in neighbouring countries, particularly in Denmark, Iceland and Norway. Most Faroese are citizens of the Kingdom of Denmark, in which the Faroe Islands are a constituent nation. The Faroese language is one of the North Germanic languages and is closely related to Icelandic and to western Norwegian varieties. Origins The first known settlers of the Faroe Islands were Gaelic hermits and monks who arrived in the 6th century. The Norse-Gaels started going to the island in the ninth century; they brought Norse culture and language to the islands with them. Little is known about this period, thus giving room for speculation. A single source mentions early settlement, the Icelandic Færeyinga saga. It was written sometime around 1200 and explains events taking place approximately 300 years prior. According to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tendinopathy
Tendinopathy is a type of tendon disorder that results in pain, swelling, and impaired function. The pain is typically worse with movement. It most commonly occurs around the shoulder ( rotator cuff tendinitis, biceps tendinitis), elbow ( tennis elbow, golfer's elbow), wrist, hip, knee ( jumper's knee, popliteus tendinopathy), or ankle ( Achilles tendinitis). Causes may include an injury or repetitive activities. Less common causes include infection, arthritis, gout, thyroid disease, diabetes and the use of quinolone antibiotic medicines. Groups at risk include people who do manual labor, musicians, and athletes. Diagnosis is typically based on symptoms, examination, and occasionally medical imaging. A few weeks following an injury little inflammation remains, with the underlying problem related to weak or disrupted tendon fibrils. Treatment may include rest, NSAIDs, splinting, and physiotherapy. Less commonly steroid injections or surgery may be done. About 80% of over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neck Pain
The neck is the part of the body in many vertebrates that connects the head to the torso. It supports the weight of the head and protects the nerves that transmit sensory and motor information between the brain and the rest of the body. Additionally, the neck is highly flexible, allowing the head to turn and move in all directions. Anatomically, the human neck is divided into four compartments: vertebral, visceral, and two vascular compartments. Within these compartments, the neck houses the cervical vertebrae, the cervical portion of the spinal cord, upper parts of the respiratory and digestive tracts, endocrine glands, nerves, arteries and veins. The muscles of the neck, which are separate from the compartments, form the boundaries of the neck triangles. In anatomy, the neck is also referred to as the or . However, when the term ''cervix'' is used alone, it often refers to the uterine cervix, the neck of the uterus. Therefore, the adjective ''cervical'' c ...

Low Back Pain
Low back pain or wiktionary:lumbago#Etymology, lumbago is a common musculoskeletal disorders, disorder involving the muscles, nerves, and bones of the back, in between the lower edge of the ribs and the lower fold of the buttocks. Pain can vary from a dull constant ache to a sudden sharp feeling. Low back pain may be classified by Pain#Chronic versus acute, duration as acute (pain lasting less than 6 weeks), sub-chronic (6 to 12 weeks), or chronic (more than 12 weeks). The condition may be further classified by the underlying cause as either mechanical, non-mechanical, or referred pain. The symptoms of low back pain usually improve within a few weeks from the time they start, with 40–90% of people recovered by six weeks. In most episodes of low back pain a specific underlying cause is not identified or even looked for, with the pain believed to be due to mechanical problems such as muscle strain, muscle or joint strain. If the pain does not go away with conservative treatmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
