“…[ 7 , 8 ] Similar to the study of Giacomini et al,[ 7 ] we observed a significant difference in postural balance between the SSc and control groups. Contrary to our study results, Lima et al[ 8 ] stated that they did not find any significant difference in any of the variables of postural balance in SSc and control groups. We think that the results may be inconsistent because the average age of the mentioned study was younger than our participants and also the exclusion criteria and the methods used in balance assessment were different from ours.…”

“…To obtain a power of 85% with a probability of a two-tailed Type I error of 0.05, a sample of 30 subjects was required in each group to demonstrate a significant difference on the BBS score. [ 8 ] Power analysis was calculated by the G*Power 3.1 program (Heinrich-Heine-Universität Düsseldorf, Düsseldorf, Germany). A p value <0.05 was considered statistically significant.…”

“…Moreover, the possible mechanisms that may lead to postural balance impairment are still unknown. 7,8 Postural balance is a complex mechanism that entails any stimulus and/or response interaction from the vestibular, visual, musculoskeletal, and somatosensory systems and the effector portion is related to postural control motor reactions. Any deterioration in these balance-related systems compromises the control of the postural balance through impaired integration and accuracy of sensory information and/or motor responses.…”

Postural balance and fall risk in patients with systemic sclerosis: A cross-sectional study

Objectives: This study aims to assess postural balance, fall risk, and the relationship of these parameters with disease-related factors in patients with systemic sclerosis (SSc). Patients and methods: Thirty patients with SSc (6 males, 24 females; mean age 51.1±10.6 years; range 35 to 65) and 30 healthy subjects (6 males, 24 females, mean age 52.4±8.7 years; range 35 to 65) matched for age, sex and body mass index were included in this cross-sectional study conducted between September 2018 and November 2019. Postural balance was measured with Biodex Balance System™ (Biodex-BS), Berg Balance Scale (BBS), and Timed Up and Go (TUG) test. Individuals' history of falls in the past year, functional capacity, lower limb muscles strength, pulmonary function, respiratory muscle strength, diffusion capacity, and dyspnea severity were evaluated. Results: The SSc group had postural balance impairment and a higher fall frequency than the control group. The SSc group had significantly higher sway index on postural stability (0.6±0.5), lower directional control score (42.1±8.0), and longer test duration (51.8±11.8) on limit of stability of Biodex-BS, lower BBS score (51.5±4.9), and longer test duration on TUG test (8.3±2.7) than control group (all p<0.05). Also, SSc group exhibited significantly lower functional capacity, limb muscles strength, pulmonary function, respiratory muscles strength, diffusion capacity, and higher dyspnea severity than control group (all p<0.05). The postural balance and fall frequency of SSc patients were significantly associated with functional capacity, lower limb muscles strength, pulmonary function, respiratory muscle strength, diffusion capacity, and dyspnea severity. Conclusion:Our results suggest that postural balance impairment and fall risk should be assessed as they appear to be important problems in patients with SSc. Furthermore, assessment of functional capacity, lower limb muscles strength, and lung involvement may highlight those with postural balance impairment and higher fall risk.
