Most all physical and occupational therapists as well as assistants are familiar with the use and indications for hot packs: increases vasodilation resulting in increased blood flow; reduction of pain and muscle spasms. Seems basic enough – obtain the hot pack, wrap in covering apply to the patient, check at intermittent intervals to ensure patient comfort. Remove after pre-determined time frame. No problem, right? Actually no, problems can arise ~ this “non-skilled” intervention can be the cause of patient injuries. Just because it seems basic, doesn’t mean that we can take the treatment for granted and not pay adequate attention to the application.
