It is performed by physical therapists (known as physiotherapists in many countries).Physical therapists also practise in the non-patient care roles such as health policy, health insurance, health care administration and as health care executives. Physical therapists are involved in the medical-legal field serving as experts, performing peer review and independent medical examinations.. Treatments focus mainly on improving gross and fine motor skills, balance and coordination, strength and endurance as well as cognitive and sensory processing/integration.Education varies greatly by country. The span of education ranges from some countries having little formal education to others having doctoral degrees and post doctoral residencies and fellowships.
