Improvement in both exercise tolerance and symptoms of dyspnoea and fatigue. Evidence to show reduce exacerbations and hospital admissions.,BTS & GOLD,Pulmonary Rehabilitation,Ideally Comprises of: Exercise Empowerment Diet Psychological well-being,PR & Exercise,Supervised training 2 - 5 times per week Minimum 20 - 30 minutes each time (may take a time to reach this level) Course duration of 4 - 12 weeks It should involve both upper & lower limb exercises both for endurance and strength,Components of Exercise Prescription,Mode (Type of exercise) Intensity Duration Frequency Progression of Exercise Programme,PR & Exercise,STRETCHING of the major muscle groups of both upper and lower extremities. AEROBIC EXERCISES e.g. walking, cycling, rowing, swimming, etc. FREQUENCY - is 2 to 5 times per week with aim of daily routine. INTENSITY- “maximum limit tolerated by symptoms” or to 60 to 75% of maximal heart rate DURATION - 20 to 30 min of continuous exercise OR if this is not possible, interval training = two to three min of high-intensity training alternating with equal periods of rest.,PR & Diet,COPD can be adversely affected if the patient is malnourished or overweight. The former leads to muscle bulk loss (diaphragm & accessory muscles of respiration) and the latter an extra burden on the cardio-respiratory system,SPIRIVA demonstrates superior improvements in breathlessness post rehab,Combined rehab with SPIRIVA results in extended, superior outcomes in breathlessness compared with rehab alone,Casaburi, et al Chest 2005,物理治療方法,EIA in Children: Scope of the Problem,EIB may interfere with physical activity and personal morale.,Adapted from American Lung Association.
