INTRODUCTION: Gait asymmetry can become very pronounced in patients who have suffered a stroke. The impairment of trunk function in some stroke patients can restrict thorax mobility and cause respiratory muscle weakness. Trunk and neck dysfunction are believed to affect the gait in stroke patients. OBJECTIVE: This study aimed to investigate the relationship between gait asymmetry and respiratory function in stroke patients by measuring the step time and trunk acceleration. METHODS: This study employed a cross-sec- tional design. Thirty stroke patients participated in this study. The symmetry index (SI) and Lissajous index (LI) were used to evaluate asymmetry during walking. The respiratory function and respiratory muscle strength were evaluated by spirometry. We examined the relation between SI or LI and the respiratory function/respiratory muscle strength in patients with stroke. RE- SULTS: The results of our analysis demonstrated that the SI was significantly correlated with the inspiratory and expiratory muscle strength and the LI was significantly correlated with the percentage of the predicted vital capacity (respectively, r = ﹣0.386, r = ﹣0.392, r = ﹣0.446; p < 0.05). CONCLUSION: The present study is the first to indicate a relationship between gait asymmetry and respiratory function in stroke patients.
