The aim of this observational study was to learn about the characteristics of dysfunctional breathing in individuals with thoracic outlet syndrome. The main question to be answered is:
Is there a dysfunctional breathing pattern in individuals with Thoracic outlet syndrome? These features will be compared with a healthy control group to evaluate the association of Thoracic outlet syndrome with dysfunctional breathing

Primary outcome measure(s)
Nijmegen Questionnaire — Day 1 A cut-off score of ≥20 in Nijmegen will be used to define dysfunctional breathing. The minimum score is 0 and the maximum score is 60 points. Higher scores mean worse outcome.
End tidal CO2 — Day 1 A standard value of \<35 mmHg will be used as the cut-off point for dysfunction
Manual Assessment of Respiratory Motion — 5 minutes This technique is used to assess and measure the distribution of respiratory movement between the upper and lower parts of the rib cage and abdomen
