Physical therapy helps develop the strength and range of motion children need to move through their environment easily and effectively. Physical therapy goals often include help with developmental milestones like sitting, standing, crawling and walking. Physical therapists also assess the need for orthotics (such as splints and braces), and evaluate and provide treatment for children who have difficulties with motor skills. Pediatric physical therapy assists in early management of infants, children, and adolescents with a variety of injuries, disorders and diseases that affect the muscles, bones, and joints. Treatments focus on improving gross and fine motor skills, balance, coordination, strength, and endurance.
