Only the body louse is known to spread disease. Lice infestations (pediculosis and pthiriasis) are spread most commonly by close person-to-person contact. Dogs, cats, and other pets do not play a role in the transmission of human lice. Lice move by crawling; they cannot hop or fly.
Physical therapists also work with children who have major injuries or health conditions, such as cerebral palsy. They address the usual issues of range of motion, strength, endurance, and mobility. Also, the therapist considers the child's special growth and developmental needs.
A physical therapist works with a patient. People who have been in accidents or have disabling conditions such as low-back pain, arthritis, heart disease, fractures, head injuries and cerebral palsy turn to physical therapists, commonly called PTs, for help.
