Overview

This multiphasic study develops and validates a biofeedback device for measuring thoracic expansion, enhancing clinical assessments.

Key Points

  • The aim is to develop a biofeedback integrated device to accurately measure thoracic expansion and improve lung volume assessment.
  • Conducted a multiphasic study with three phases: prototype development, reliability/validity testing, and effectiveness evaluation.
  • Assessed device reliability using the ICC test in a test-retest method.
  • Evaluated concurrent validity against a measuring tape using Spearman correlation.
  • The device demonstrated excellent reliability with a high ICC score.
  • Found strong agreement with traditional measurement methods, as confirmed by Spearman correlation.
  • Statistically significant differences (<0.05) in thoracic expansion were noted before and after interventions.
