Protection phase. Clinical Signs Inflammation Pain BEFORE tissue resistance (due to mm guarding) PT Goals Control inflammation and effects Prevent adverse effects of rest Management Educate on protective measures Control pain, edema, spasm (modalities) Maintain soft tissue integrity (gentle isometrics, PROM, etc)

Reactive assessments

Push and release test: the patient leans back pressing on the hands of the examiner; the examiner then suddenly removes their hands. Scores are based on the patient's correctional response when trying to regain balance. Scoring criteria are as follows: 0= recovers independently with 1 step of normal length and width 1= two to three small steps backward, but recovers independently 2= 4 or more steps backward, but recovers independently 3= steps but needs to be assisted to prevent a fall 4= falls without attempting a step or unable to stand without assistance Pull test: subject stands in a comfortable stance with eyes open (have feet shoulder width apart if they assume an unusually wide or narrow stance.) examiner stands behind the subject. The suject is instructed to do whatever it takes to not fall and are told that the examiner will catch them if the do fall. The examiner gives a sudden, brief backward pull to the shoulders with sufficient force to cause the subject to have to regain their balance. The subject should not know exactly when the pull is coming. Scoring is from 0 to 4 with 0= recovers independently may take 1 or 2 steps or an ankle reaction; 1= three steps or more backward but recovers independently; 2= retropulsion, needs to be assisted to prevent fall; 3= very unstable, tends to lose balance spontaneously; 4= unable to stand without assistance (UPDRS method) Interventions: Standing perturbations (all directions, small/large, fast/slow). Catching a ball (vary size/weight). Balance beam. SLS while looking or reaching in different directions.

Joint Mobilization Application

All joint mobilizations follow the convex-concave rule •Patient should be relaxed & comfortable •Explain purpose & expectations (how will it feel?) •Evaluate motion BEFORE, & pt response AFTER treatment •Stop the treatment if it is too painful for the patient •Use proper body mechanics •Use gravity to assist the technique if possible •Begin & end treatments with Grade I or II oscillations

Motor Strategies:

Activates primarily hip muscles. Also can activate ankle muscles Suspension strategy (sagittal plane): used to lower the COM to allow greater control. Important when both mobility and stability are required. Hip strategy (sagittal plane): elicited by greater (larger range, faster) perturbations. Muscles contract proximal to distal Stepping strategy (all planes): elicited through: unexpected perturbations in static standing, perturbation that puts COM outside BOS. Includes stepping and/or reaching to widen/move BOS or regain new BOS

Bony block Unhealed fracture Acute inflammation or infection Sharp pain with movement Hematoma Hypermobility Hypomobility is desired. Improves function and provides needed stability

Acute physiologic response to exercise:

Cardiovascular Increased HR (increased freq. of SA node depolarization) Increased myocardial contractility Increased cardiac output Increased systolic blood pressure Decreased total peripheral resistan Respiratory Increased alveolar ventilation TV and RR increase (minute ventilation)

Chronic physiologic adaptations to exercise:

Cardiovascular: Decreased resting HR and BP Increased blood volume and hemoglobin Decreased VO2 at submax (only if efficiency of motion improves) Increased VO2 max Muscle: Increased myoglobin and capillary density Increased number and size of mitochondria Increased concentration of enzymes that help speed ATP formation via oxidative metabolism (Changes above all help increase O2 use by muscle) Respiratory: In a person with healthy lungs, respiratory ability should not limit aerobic exercise. We can all move plenty of air. Lack of blood flow to both the lungs and the muscles is usually the limiting factor, Larger lung capacity (no not really, TLC is based on height/rib cage diameter which don't change) Greater diffusion capacity (more alveolar surface area) (the # of alveoli doesn't change, we breathe more deeply so we use more of the alveoli we always had and most importantly we can send more blood to lungs to pick up more O2 and drop off more CO2) Increased maximal ventilation capacity- respiratory muscles (diaphragm, intercostals) can contract more efficiently and rapidly to move larger volumes of air per minute
