The high frequency chest wall oscillation known as the most effective airway clearance therapy is gradually expanding its indications through active research.

• Effect of the High Frequency Chest Wall Oscillation (HFCWO) on Pulmonary Function and Walking Ability in Stroke Patients

  Effect of the High Frequency Chest Wall Oscillation (HFCWO) on Pulmonary Function and Walking Ability in Stroke Patients

  Conclusion : The TT(threadmill training) and HFCWO effectively improved pulmonary function and walking ability in subjects with stroke. The proposed program can be applied to stroke patients as a useful therapy.

• OUTCOMES OF HIGH FREQUENCY CHEST WALL OSCILLATION (HFCWO) IN COPD PATIENTS WITHOUT BRONCHIECTASIS

  OUTCOMES OF HIGH FREQUENCY CHEST WALL OSCILLATION (HFCWO) IN COPD PATIENTS WITHOUT BRONCHIECTASIS

  Conclusion : This study shows that outcomes in COPD patients without bronchiectasis, as measured by number of hospitalizations, self-reported respiratory health, and the ability to clear secretions, improved substantially after the initiation of HFCWO therapy. These improvements were sustained for at least one year.

• High-Frequency Chest-Wall Compression During the 48 Hours Following Thoracic Surgery

  High-Frequency Chest-Wall Compression During the 48 Hours Following Thoracic Surgery

  Conclusion : HFCWC is a safe, well-tolerated adjunct after thoracic surgery. The observation of hemodynamic stability is especially important, considering that the patients were studied in the early postoperative period, during epidural analgesia.

• Safety and effectiveness of the high-frequency chest wall oscillation vs intrapulmonary percussive ventilation in patients with severe COPD

  Safety and effectiveness of the high-frequency chest wall oscillation vs intrapulmonary percussive ventilation in patients with severe COPD

  Conclusion : The two techniques improved daily life activities and lung function in patients with severe COPD. IPV demonstrated a significantly greater effectiveness in improving some pulmonary function tests linked to the small bronchial airways obstruction and respiratory muscle strength and scores on health status assessment scales (BCSS and CAT) as well as a reduction of sputum inflammatory cells compared with HFCWO.

• Effectiveness of treatment with high-frequency chest wall oscillation in patients with bronchiectasis

  Effectiveness of treatment with high-frequency chest wall oscillation in patients with bronchiectasis

  Conclusion : The HFCWO technique provides an improvement both in pulmonary function and quality of life related parameters in patients with chronic hypersecretive disease. Since those patients need daily airway clearance, this treatment should be included among the principal options in chest physiotherapy. The study was registered as ChiCTR-TRC-12002134 at.

• Short-Term Effects of High-Frequency Chest Compression and Positive Expiratory Pressure in Patients With Cystic Fibrosis

  Short-Term Effects of High-Frequency Chest Compression and Positive Expiratory Pressure in Patients With Cystic Fibrosis

  Conclusion : High-frequency chest compression and positive expiratory pressure mask have comparable short-term effects on expectorated sputum and lung function. Although positive expiratory pressure mask was associated with a lower SpO2, it was better tolerated than high-frequency chest compression.

• The Impact of High-Frequency Chest Wall Oscillation on Healthcare Use in Patients with Neuromuscular Diseases

  The Impact of High-Frequency Chest Wall Oscillation on Healthcare Use in Patients with Neuromuscular Diseases

  Conclusion : Total medical costs, hospitalizations, and pneumonia claims were less after than before initiation of HFCWO in a broad group of patients with neuromuscular disease. Subject to the limitations that administrative data did not capture how HFCWO was used and that HFCWO may be a marker of generally better care, our findings lend support to the routine use of this intervention in the care of patients with neuromuscular diseases.

  High-Frequency Chest Wall Oscillation in Patients with COVID-19: A Pilot Feasibility Study

  Conclusion : This study demonstrated that pulmonary rehabilitation applied with the HFCWO device in patients with COVID-19 in the early period contributed to the improvement of oxygenation by providing significant improvement as observed in the PFTs of the patients.

• The Efficacy of High-frequency Chest Wall Oscillation (HFCWO) for the Improvement of Symptoms in Children with Mycop asma pneumonia

  The Efficacy of High-frequency Chest Wall Oscillation (HFCWO) for the Improvement of Symptoms in Children with Mycop asma pneumonia

  Conclusion : Our findings demonstrate that combination of adjuvant treatmentwith HFCWO may help children withM. pneumoniae pneumonia to achieve clear improvements in clinical symptoms, reduce the length of hospital stays, and reduce costs. Further studies, incorporating multiple centers, are now needed to evaluate clinical efficacy, tolerability, adverse effects, and cost effectiveness.
