Abstract
People with spina bifida have hypoactive lifestyles that are the consequence of lower extremity functional limitations. However, several secondary conditions, such as scoliosis, pneumonia, and obesity may affect activity performance. Even socio-demographic factors, such as lack of accessible transportation to fitness facilities or having low income may affect activity performance as well. Few studies have investigated pulmonary function in people with spina bifida. In the present study, pulmonary function tests (PFTs) and graded arm ergometry exercise stress tests were conducted among adolescents and adults with spina bifida (n = 29). The primary aim of this study was to investigate the relationship between pulmonary function and exercise capacity among people with spina bifida. Another aim of this study was to develop and to validate a newly developed perceived exertion scale (the WHEEL Scale) for regulating exercise intensity for people with spina bifida. Socio-demographic information, body composition measurements, and medical record information were collected in this study and were used as predictors for PFTs and peak oxygen consumption (peak VO2). The results showed that more than 65% of participants met the criteria of pulmonary restriction and 90% of the people who were not able to achieve a maximal exercise test had pulmonary restriction. Significant models for predicting PFTs and peak VO2 were found and established in this study. The concurrent validity and construct validity of the newly developed WHEEL Scale were established by using relative heart rate (HR) and relative peak VO2 from the graded arm ergometry exercise stress test. Concurrent validity of the WHEEL Scale was established by the finding that the WHEEL scale significantly correlated with relative VO2 and relative HR. Construct validity of the WHEEL Scale was established by the finding that the WHEEL scale significantly correlated with the Borg Scale. Future studies in a large cohort of individuals with spina bifida are needed to confirm the results and establish the inter-rater and intra-rater reliability of the WHEEL Scale.
