Aim: Balance disorders, postural dysfunctions, and speech disorders are common after stroke. This study aims to investigate whether there is a connection between language and speech function and posture and balance in paralyzed patients and to which speech area function the connection is related.Methods: Eighteen stroke patients with speech impairment and no cognitive impairment were included in the study. Balance and postures of stroke patients were evaluated using the Berg Balance Test (BBT) and Postural Assessment Scale for Stroke Patients (PASS-T), while their quality of life was evaluated using the Stroke and Aphasia Quality of Life-39 Test (SAQOL-39). Patients’ speech functions were evaluated using the Gülhane Aphasia Test-2 (GAT-2), voice-related assessments were made with the Voice-Related Quality of Life Scale (V-RQOL), and objective voice analysis.Results: The mean age of the participants was 59.10±14.72 years, the mean score of the Mini-Mental Test was 26.16±2.00. According to statistical analysis, there was a significant relationship between BBT score and GAT-2 (r: 0.552, p=0.017), and BBT score and SAQOL-39 mean score (r: 0.589, p=0.010), there was no significant relationship between BBT and V-RQOL (r: -0.075, p=0.768). While there was a significant relationship between PASS-T (r: 0.499, p=0.035) and SAQOL-39, no significant relationship was found with GAT-2 (r: 0.388, p=0.112). In addition, a significant correlation was found between the SAQOL-39 mean score and the GAT-2 total score (r: 0,606, p=0.008).Conclusion: It was observed that there is a significant relationship between balance functions and speech function and quality of life, and patients with good balance have better functional independence and speech functions. However, it was found that posture did not change speech function. Due to the importance of evaluation in treatment, it is thought that the evaluation of stroke patients who will receive speech and language therapy in terms of balance and postural functions will contribute to the speech functions of patients.
