A therapy assistant is an aide for a physical therapist. You assist the therapist as they help patients with physical injuries or illnesses recover through treatment and occupational therapy. You work under the supervision of physical therapists in an office or hospital setting. Your job duties include setting up equipment, collecting patient data, observing exercises and care plans, and using massage or stretching techniques to treat patients. Interpersonal skills are vital in this career, as are first-aid and CPR experience. Aides must be compassionate, detail oriented, and able to stand on their feet for long periods of time.
