Neuromuscular massage is applied to specific muscles and helps release tension and knots, relieve pain and release pressure on nerves, and increase blood flow.AAH Yes!TractionThe pulling or stretching of the musculoskeletal system UsesCreate and maintain bone alignmentReduce and prevent joint stiffeningCorrect deformitiesReduce and relieve muscle spasmsTraction (cont.)ManualGentle pull on muscles and jointsImproves motion and decreases stiffeningStaticHarness and weightsUsed to relieve muscle spasmsTraction (cont.)Skeletal – performed for injuries requiring long traction time and heavy weightsMechanical – device that intermittently pulls and relaxes Apply Your KnowledgeTrue or False:___ Static traction uses a harness and weights to induce  muscle spasms. ___ Manual traction stretches muscles and separates joints by  gently pulling on them.___ Skeletal traction uses pulleys and weights to provide  continuous traction.___ Mechanical traction maintains constant tension on the extremity.FTTFANSWER:FANTASTIC!Mobility AidsDevices to improve patients’ ability to ambulate or move aboutMobility aid chosen depends onPatient’s disabilityMuscle coordinationStrength Age CanesStandard – provide small amount of supportTripod and quad-base Correct heightElbow bent 20-25 degreesShould not lean on canefor supportWalkersUsed by patients whoCannot walk unassistedHave balance problems Provides a sense of stabilityAdjust to proper height for patientCrutchesTransfers weight to the armsTypes Axillary Ground to axillaShort-term useLofstrand, or CanadianGround to forearmLong-term useCrutches (cont.)Measure to fitToo long Crutch palsyBack pain Too short Back painImbalanceCrutches (cont.)Crutch gaitsTripod or standing positionDetermine proper gaitSlow or fast gaitsCrutches (cont.)Four-point gaitSlow gaitBear weight on both legsStable and saveCrutches (cont.)Three-point Cannot bear weight on one legMust have good muscle coordination and arm strengthCrutches (cont.)Two-point Swing gaitSwing-to Swing-through WheelchairsType of chairDepends on patient’s disability Length of time wheelchair neededAlways ensure patient safety during transfersUse appropriate lifting techniquesReferral to a Physical TherapistReferrals Provide physician’s orderProvide patient informationTherapists Independent practitionersHospital or clinicHome health Apply Your KnowledgeWhen would a walker be an appropriate mobility device for use by your patient? ANSWER: Walkers are usually used by patients who are too weak to walk unassisted or who have balance problems.Hurray!What is the role of the medical assistant related to referrals for physical therapy ANSWER: The medical assistant may be asked to contact the therapist directly or to give the patient a written order and information about contacting the therapist. The referral must also be documented in the patient’schartIn Summary54.1 Physical therapy is a medical specialty for the treatment of musculoskeletal, nervous, and cardiopulmonary disorders using a variety of treatments, including cold, heat, water, exercise, massage, and traction. In Summary54.2 There are various types of cold and heat therapies, including dry and wet cold and heat applications. Cold and heat therapy promote healing and increase patient comfort. Contraindications to cold and heat therapies include circulation problems, pain, and hemorrhageIn Summary (cont.)54.3 Various types of hydrotherapy used to treat physical problems include whirlpools, contrast baths, and underwater exercises. 54.4 There are several methods of exercise therapy, including active mobility, passive mobility, aided mobility, and active resistance. In Summary (cont.)54.5 The two major types of massage used in rehabilitation therapy are Swedish and neuromuscular. Swedish massage uses 5 basic strokes to manipulate soft tissues. Neuromuscular massage is applied to specific muscles and helps release tension and knots, relieve pain and release pressure on nerves, and increase blood flow. In Summary (cont.)54.6 The different methods of traction used to treat physical problems include manual, static, skeletal, and mechanical54.7 The various mobility aids include 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. In Summary (cont.)54.8 You may be asked to contact the specialist directly or to give the patient a written order and information about contacting the specialist. Keep a file with information about the therapists your office uses, noting the forms and information each therapist requiresEnd of Chapter 54Disability is a matter of perception.
