  15. PULMONARY REHABILITATION • CHEST WALL DISORDERS • NEUROMUSCULAR DISEASE

  16. RATIONALS ?

  17. Reduced thoracic wall compliance Positional mechanical disadvantage Respiratory muscle weakness? Restrictive pulmonary function impairment Alveolar hypoventilation + V/Q mismatch HYPOXEMIA + HYPERCAPNIA

  18. Reduced thoracic wall compliance Positional mechanical disadvantage Respiratory muscle weakness ? Restrictive pulmonary function impairment Alveolar hipoventilation + V/Q mismatch SYMPTOMS Rapid shallow breathing Dyspnea Peripheral muscle weakness NIPPV RMT Reduction in exercise tolerance HYPOXEMIA + HYPERCAPNIA

  19. VO2 peak ↑(13.6±2.8, 14.8 ± 2.8) • 6 MWD↑ (399±62, 467±65) Internal medicine 2006

  20. MRC ADL 6 DYT Pulmonary rehabilitation is effective in symptomatic patients with Post TB 6DYT Chest 2003;123:1988-95

  21. Respiratory muscle weakness Peripheral weakness Anatomical changes Reduced tidal volumes Reduced lung compliance Ineffective cough General fatigue Decreased mobility Positioning limitations Possible impaired swallowing and increased risk of aspiration Problems faced Faced Problems

  22. AIMS PR • Reduce work of breathing Increase tidal volumes and maintain lung compliance • Improve secretion clearance and effectiveness of cough • Maximise independence • Optimise quality of life NIMV Breathing exercise

  23. Breathing work rate increase induce reductions in VO2 demand for peripheral muscles • Reduction in work load of respiratory muscles serve for peripheral muscles BORG Harms et al. J Appl Physiol 1997; 1573-1583 Bianchi L, et al, ERJ, 1998 Time

  24. Short-Term Effect of Nasal Intermittent Positive-Pressure Ventilation in Patients with Restrictive Thoracic DiseasePınar Ergün, Gülümser Aydın, Ülkü Yılmaz Turay, Yurdanur Erdoğan, Atalay Çağlar, Çiğdem Biber Respiration 2002;69:303-308 ATS dispnea score: 2.5 ± 0.9’-1.6 ± 0.4 (p < 0.01) 6MWD 320.66 ± 93.56 to 382.41 ± 121.20 m (p < 0.05)

  25. Respiratory Muscle Training Changes in Airway Resistance (?) Changes in Chest Wall Changes in Compliance Changes in muscle length Increased Demands Nutrients and O2 Nutrients and O2 Delivery can be compromised Physiopathology Skoliosis Cyphosis Cyphoskoliosis

  26. Respiratory Muscle Training Chest Wall Deformities & RM Training Rest Training Few studies RM training appears to improve - Lung function, dyspnea & exercise tolerance Effects on the disease time-course: unknown

  27. RESPIRATORY MUSCLE TRAINING Changes in Airway Resistance (?) Changes in Thorax Geometry Changes in Compliance Inefficiency of Muscles Increased Demands Nutrients and O2 Amyotrophic Lateral Sclerosis Multiple Sclerosis Spine Cord injury Miasthenia Gravis Duchenne’s Muscular Dystrophy Post-polio Syndrome Guillain-Barré Syndrome Myotonic Dystrophy (Steinert’s Disease) Nutrients and O2 Delivery can be compromised Physiopathology

  28. RESPIRATORY MUSCLE TRAINING Neuromuscular Diseases & RM Training Rest Training • Few studies • Education, coordination • Insuflation (active and pasive) • RM training: controversial • - Early, Mild disease, Slow evolution • - Balance with rest

  29. Results: Intermittant-RMT is effective in generalized MG patients in improving respiratory muscle force and patern,endurance. Chest 2005;128:1524-30 Chest 2001;120:765-69

  30. PULMONARY REHABILITATION; is indicated in ALL patients with chronic respiratory diseases who is sypmtomatic and whose health related quality of life is impaired

  31. Core Components of PR for the “Non-COPD” Patient • Patient Assessment • Exercise • Education • Psychosocial/Nutritional intervention • Outcomes measurement

  32. Special Considerations in Patient Assessment • CPET: -identify exercise factors contributing to symptoms and limitation -formulate the exercise prescription -Identify pulmonary vascular or cardiac limitations and/or need for supplemental O2 -Incremental exercise to high intensity NOT recommended for known severe pulmonary HTN or degenerative neuromuscular disease • Asses candidacy for inpatient PR

  33. Core Components of PR for the “Non-COPD” Patient • Patient Assessment • Exercise training • Education • Psychosocial/Nutritional intervention • Outcomes measurement

  34. Interstitial lung disease; Pacing and energy conservation techniques Slow and deep breathing Adequete oxygenation DISEASE SPECIFIC CONSEDERATOIN IN EXERCISE TRAINING (I)

  35. Neuromuscular and Chest wall disease Maintain conditioning, avoid fatigue Consultation with neurologist/physiatrist Low intensity aerobic/water-based exercise Shorter, more frequent exercise sessions Emphasis on optimizing functional status Acclimatization to non-invasive ventilation Disease-specific Considerations in Exercise Training (II)

  36. Disease-specific Considerations in Exercise Training (III) • Obesity related respiratory diseases • Strength and endurans exercise training/ Upper and Lower extremity • Consider low-impact water-based exercise • Bariatric equipment may be needed • Cardiac and musculo skeletal intervention before enrollment

  37. EXERCISE TRAINING Aerobic and Strength Training • No evidence-based guidelines for exercise prescription or training • Mode, intensity and duration individualized to patient ability and need using resources available • Age- and interest- specific modes oxygen saturation > 90% • Maintain Meet metabolic needs, avoid anaerobic metabolism and exercise-induced increased PA pressure • Test O2 saturation using patients’ own portable system

  38. Core Components of PR for the “Non-COPD” Patient • Patient Assessment • Exercise • Education • Psychosocial/Nutritional intervention • Outcomes measurement

  39. EDUCATION: • PR program staff: Knowledge of physiologic basis of exercise/functional impairment, symptoms and available therapies for different disorders • PATIENT and FAMILY • Nature and expected course of disease • Physiologic basis of symptoms an exercise limitations • Rational for and proper use of supplemental oxygen • Pulmonary drainage technigues • Nutrition • Recognition of symptoms and sings of secondary infection • Prevention strategies • Coping techniques for assistance in managing anxiety and depression • Training options for and outcomes of mechanical ventilation

  40. DISEASE SPECIFIC PROGRAM MANAGEMENT • Ensure patient safety,individual goals • Individual education sessions may be needed • Written and video educational materials • Assess outcomes acording to goals Individual, disease specific approaches is necessary

  41. AGHH Pulmonary rehabilitation unit documents; 2005- 2007 • 2days in a week / 8 week • Patient number completed the program ;71 • 49 COPD: (Stage I)=5 • ( Stage II)=10 • (Stage III)= 18 • (Stage IV)= 16 • 3 Persistant Asthma • 7 Bronchiectasis • 4 Kyphoscolyosis + restrictive LD • 1 Pneumoconiosis • 1 IPF • 1 Sarcoidosis
