These include dry and wet, cold, and heat applications.42.6 The general steps to applying cold and heat therapies include checking the physician’s order, positioning and draping the patient, applying the pack, and monitoring the patient.42.7 Various types of hydrotherapy used to treat physical problems include whirlpools, contrast baths, and underwater exercises.42-*In Summary (cont.)42.8 There are several methods of exercise therapy, including active mobility, passive mobility, aided mobility, and active resistance.42.9 The different methods of traction used to treat physical problems include manual, static, skeletal, and mechanical.42.10 There are various mobility aids, including canes, walkers, crutches, and wheelchairs. Specific instructions for each of these aids must be followed to reduce the possibility of patient injury during their use.42-*End of Chapter 42Disability is a matter of perception.
