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 therapy and recovery from injury. Physical therapy can help you recover from an injury and avoid future injury. Your physical therapist can help you reduce pain in the soft tissues (muscles, tendons, and ligaments), build muscle strength, and improve flexibility, function, and range of motion.
The work of physical therapists varies by type of patient. For example, a patient experiencing loss of mobility due to stroke needs different care from that given to an athlete recovering from an injury. Some physical therapists specialize in one type of care, such as orthopedics or geriatrics. Many physical therapists also work at preventing loss of mobility by developing fitness and wellness programs to encourage healthier and more active lifestyles.
