Summary

Hereditary neurodegenerative diagnosis of Huntington's disease (HD) is associated with a progressive deterioration of the respiratory system function . This fact contributes strongly to the increased risk of aspiration pneumonia as a primary cause of death in people with HD. But regularly objective monitoring of the airway system condition is in common clinical practice almost impossible for high time requirements and the need for specialized expensive devices . This drives the need for a simpler and more cost-effective screening tool. In recent years published studies, working with all ages and genders, show correlation between hand grip strength (HGS) and respiratory parameters. As a second simple screening tool, we chose a short questionnaire called the Index of pulmonary dysfunction.

Detailed description

Goal: To identify a simple method for screening respiratory muscle and cough weakness in Huntington\'s Disease (HD) patients, suitable for clinical practice. Hypothesis 1: Maximal inspiratory pressure, maximal expiratory pressure, and voluntary peak cough flow will be significantly correlated with maximal hand grip strength in HD patients. Hypothesis 2: Maximal inspiratory pressure, maximal expiratory pressure, and voluntary peak cough flow will be significantly correlated with the Index of pulmonary dysfunction in HD patients.

Conditions

• Huntington Disease

Interventions

Type	Name	Description
OTHER	Assessment of respiratory paramenters (Maximal inspiratory pressure, maximal expiratory pressure, and voluntary peak cough flow))	The voluntary peak cough flow is measured using a pneumotachograph (BTL cardiopoint Spiro, BTL industries), which meets the recommendations of the American Thoracic Society and the European Respiratory Society for range and accuracy in forced expiratory maneuvers. Maximal expiratory and inspiratory pressures assessments were performed using a flanged rubber mouthpiece connected to a pressure manometer (Micro RPM, Vyaire Medical). Assessments are conducted according to the statements on respiratory muscle testing of the American Thoracic Society and the European Respiratory Society. Hand grip strength Grip strength is measured using DHD-1 digital hand dynamometer (SAEHAN®,Seahan Corporation), assessment follows recommendation of The American Society of Hand Therapists.
