Sitting is a basic action and resting position in which the body weight is supported primarily by the bony ischial tuberosities with the buttocks in contact with the ground or a horizontal surface such as a chair seat, instead of by the lower limbs as in standing, squatting or kneeling. When sitting, the torso is more or less upright, although sometimes it can lean against other objects for a more relaxed posture.
Exercise is physical activity that enhances or maintains fitness and overall health. It is performed for various reasons, including weight loss or maintenance, to aid growth and improve strength, develop muscles and the cardiovascular system, hone athletic skills, improve health, or simply for enjoyment. Many individuals choose to exercise outdoors where they can congregate in groups, socialize, and improve well-being as well as mental health.
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, elbow, wrist, hip, knee, or ankle.
Humanity+ is a non-profit international educational organization that advocates the ethical use of technologies and evidence-based science to improve the human condition.
Strength training, also known as weight training or resistance training, involves the performance of physical exercises that are designed to improve strength and endurance. It is often associated with the lifting of weights. It can also incorporate a variety of training techniques such as bodyweight exercises, isometrics, and plyometrics.
Sports medicine is a branch of medicine that deals with physical fitness and the treatment and prevention of injuries related to sports and exercise. Although most sports teams have employed team physicians for many years, it is only since the late 20th century that sports medicine emerged as a distinct field of health care. In many countries, now over 50, sports medicine is a recognized medical specialty. In the majority of countries where sports medicine is recognized and practiced, it is a physician (non-surgical) specialty, but in some, it can equally be a surgical or non-surgical medical specialty, and also a specialty field within primary care. In other contexts, the field of sports medicine encompasses the scope of both medical specialists as well as allied health practitioners who work in the field of sport, such as physiotherapists, athletic trainers, podiatrists and exercise physiologists.
A hip fracture is a break that occurs in the upper part of the femur, at the femoral neck or (rarely) the femoral head. Symptoms may include pain around the hip, particularly with movement, and shortening of the leg. Usually the person cannot walk.
Fall prevention includes any action taken to help reduce the number of accidental falls suffered by susceptible individuals, such as the elderly (idiopathic) and people with neurological or orthopedic indications.
Cardiac rehabilitation (CR) is defined by the World Health Organization (WHO) as "the sum of activity and interventions required to ensure the best possible physical, mental, and social conditions so that patients with chronic or post-acute cardiovascular disease may, by their own efforts, preserve or resume their proper place in society and lead an active life". CR is a comprehensive model of care delivering established core components, including structured exercise, patient education, psychosocial counselling, risk factor reduction and behaviour modification, with a goal of optimizing patient's quality of life and reducing the risk of future heart problems.
Balance in biomechanics, is an ability to maintain the line of gravity of a body within the base of support with minimal postural sway. Sway is the horizontal movement of the centre of gravity even when a person is standing still. A certain amount of sway is essential and inevitable due to small perturbations within the body or from external triggers. An increase in sway is not necessarily an indicator of dysfunctional balance so much as it is an indicator of decreased sensorimotor control.
Falls in older adults are a significant cause of morbidity and mortality and are a major class of preventable injuries. Falling is one of the most common accidents that cause a loss in the quality of life for older adults, and is usually precipitated by a loss of balance and weakness in the legs. The cause of falling in old age is often multifactorial and may require a multidisciplinary approach both to treat any injuries sustained and to prevent future falls. Falls include dropping from a standing position or from exposed positions such as those on ladders or stepladders. The severity of injury is generally related to the height of the fall. The state of the ground surface onto which the victim falls is also important, harder surfaces causing more severe injury. Falls can be prevented by ensuring that carpets are tacked down, that objects like electric cords are not in one's path, that hearing and vision are optimized, dizziness is minimized, alcohol intake is moderated and that shoes have low heels or rubber soles.
Falling is the action of a person or animal losing stability and ending up in a lower position, often on the ground. It is the second-leading cause of accidental death worldwide and a major cause of personal injury, especially for the elderly. Falls in older adults are a major class of preventable injuries. Construction workers, electricians, miners, and painters are occupations with high rates of fall injuries.

Femoroacetabular impingement (FAI) is a condition involving one or more anatomical abnormalities of the hip joint, which is a ball and socket joint. It is a common cause of hip pain and discomfort in young and middle-aged adults. It occurs when the ball shaped femoral head contacts the acetabulum abnormally or does not permit a normal range of motion in the acetabular socket. Damage can occur to the articular cartilage, or labral cartilage, or both. The condition may be symptomatic or asymptomatic. It may cause osteoarthritis of the hip. Treatment options range from conservative management to surgery.
Kinesiophobia is the fear of pain due to movement.
Blood flow restriction training / Occlusion Training or Occlusion Training or KAATSU is an exercise and rehabilitation modality where resistance exercise, aerobic exercise or physical therapy movements are performed while using an Occlusion Cuff which is applied to the proximal aspect of the muscle on either the arms or legs. In this novel training method developed in Japan by Dr. Yoshiaki Sato in 1966, limb venous blood flow is restricted via the occlusion cuff throughout the contraction cycle and rest period. This result is partial restriction of arterial inflow to muscle, but, most significantly, it restricts venous outflow from the muscle. Given the light-load and strengthening capacity of BFR training, it can provide an effective clinical rehabilitation stimulus without the high levels of joint stress and cardiovascular risk associated with heavy-load training.
non-pharmacological intervention (NPI) is any type of healthcare intervention which is not primarily based on medication. Some examples include exercise, sleep improvement, and dietary habits.
A pediatric concussion, also known as pediatric mild traumatic brain injury (mTBI), is a head trauma that impacts the brain capacity. Concussion can affect functional, emotional, cognitive and physical factors and can occur in people of all ages. Symptoms following after the concussion vary and may include confusion, disorientation, lightheadedness, nausea, vomiting, blurred vision, loss of consciousness (LOC) and environment sensitivity. Concussion symptoms may vary based on the type, severity and location of the head injury. Concussion symptoms in infants, children, and adolescents often appear immediately after the injury, however, some symptoms may arise multiple days following the injury leading to a concussion. The majority of pediatric patients recover from the symptoms within one month following the injury. 10-30% of children and adolescents have a higher risk of a delayed recovery or of experiencing concussion symptoms that are persisting.
Exercise medicine is a branch of medicine that deals with physical fitness and the prevention and treatment of injuries and illness with exercise. In some countries, Sport and Exercise Medicine (SEM) is a recognized medical specialty. Exercise medicine is therefore an emerging physician (non-surgical) specialty, but there is also a belief that exercise is treatment of such fundamental benefit that it should be incorporated into all medical specialties. Allied health practitioners also can specialize in exercise such as exercise physiologists, physiotherapists, athletic trainers and podiatrists.
