“…Moreover, there is no study investigating the normative values of trunk strength and endurance in Turkish society, so we have referenced studies involving healthy individuals with similar characteristics to our population to demonstrate trunk strength and endurance change in our SSc patients. In the literature, reference values of trunk extensor and flexor muscle endurance tests in older (41‐65 years), inactive, asymptomatic and healthy women are indicated as 82.5 ± 19.7 and 105.9 ± 22.7 seconds, respectively 25 . The trunk extensor and flexor endurance test results of the SSc patients in our study were lower than the stated reference values and the test results of healthy individuals in other studies 8,25,26 .…”

In SSc, changes in the osteomyoarticular system, movement limitations and postural changes may occur due to skin stiffness resulting from excessive collagen accumulation in connective tissue, chronicity of the disease and side effects of treatment 27 .…”

Association between core stability and physical function, functional performance in patients with systemic sclerosis

Objective To investigate the association of core stability with physical function and functional performance in patients with systemic sclerosis (SSc). Methods Forty patients who met the American College of Rheumatology / European League Against Rheumatism 2013 classification criteria for SSc were included in the cross‐sectional study. For evaluation of core stability, trunk muscle endurance and trunk muscle strength were assessed. Trunk extensor and trunk flexor endurance tests were used for assessment of trunk muscle endurance. Trunk muscle strength was measured with a hand‐held dynamometer and modified sit‐up test. To measure physical function the Health Assessment Questionnaire Disability Index (HAQ‐DI) and to measure functional performance 6‐minute walking test (6MWT) and sit‐to‐stand test (STS) were used. Results Patients with SSc had lower mean trunk extensor and flexor endurance test times (49.87 ± 30.81 and 32.17 ± 15.42 seconds, respectively), modified sit‐up test repetition (17.42 ± 7.81) and trunk extensor and flexor muscle strength (7.48 ± 2.29 kg and 6.20 ± 1.68 kg, respectively) when compared to the reference values in healthy individuals. All measurements were used to evaluate core stability associated with HAQ‐DI score, 6DMWT walking distance and STS test duration (all P < .05). Conclusion Patients with SSc have markedly reduced core stability and this negatively affects the physical function and functional performance. Therefore, this study highlights the importance of trunk muscle in patients with SSc. We suggest that not only upper‐lower extremity muscles, but also trunk muscle strength and endurance should be measured and core stability exercises can be added to the training programs to maintain and/or improve physical functions and functional performance in SSc patients.

“…The PBFS device has also proven to be reliable in healthy individuals, but also patients with chronic low back pain or other non-specific musculoskeletal conditions. 30 A moderate to good reproducibility (intra-class correlation coefficients from 0.47 to 0.82) and acceptable construct validity (intra-class correlation coefficients from 0.48 to 0.90) was found in previous systematic review. 31 During the examination, the patient is in a prone position, the head remains in the middle line of the body, and the face faces the ground.…”

Purpose: Post-stroke hemiparesis has a significant impact on postural stability. The transversus abdominis (TrA) muscle contributes to the stability of the spine. The aim was to assess both the postural stability and the activity of the TrA muscle in overweight post-stroke patients. Methods: A group of 56 participants (61.12 ± 11.5 years) was divided into the study group (n=28 post-stroke patients, 63.7 ± 10.9 years) and control group (n= 23 healthy participants (58.5 ± 12.2 years). The Berg Balance Scale (BBS) and the Timed Up and Go Test (TUG) were used to evaluate postural stability and risk of falls. The Pressure Bio-Feedback Stabilizer (PBFS) device was used to assess functional stability. Results: Stroke had a significantly negative effect on the BBS (p < 0.001) and TUG (p = 0.001). The older age negatively affected the BBS (p = 0.001), TUG (p = 0.017), and the TrA muscle activity (p = 0.017). Higher values of body mass index (BMI) negatively affected the BBS (p = 0.028), however there were no changes of TUG results (p = 0.141), and the TrA muscle activity (p = 0.808). Also, BBS and TUG results were not associated with TrA muscle activity (p = 0.541 and p = 0.411, respectively). The results of the BBS, TUG, and PBFS did not differ according to gender (p < 0.05). Time from stroke negatively affected the TUG (p = 0.001), but had no effect on the TrA muscle activity (p < 0.05). The side of hemiparesis did not affect the postural stability (p < 0.05). Conclusion: The consequences of a stroke have an essential negative effect on postural stability. Factors such as age, gender, time from stroke, and the side of the hemiparesis have not negatively affected postural stability in overweight post-stroke patients.

“…The sample characteristics may also have influenced our findings. At baseline, both groups Injuries in treadmill runners had lower flexor, extensor, and abductor force output than 37 . Another point is that uninjured runners were overweight and injured runners were at the limit of normal BMI.…”

To determine the incidence of injuries in exclusive treadmill runners and the main associated factors in 24 weeks. Methods: The incidence of injuries was investigated every two weeks by an electronic form. To analyze the associated factors, muscle force output, range of motion, and flexibility were investigated. To perform a descriptive analysis (baseline) and injury predictive factors (regression), we divided runners into two groups, injured and uninjured. Comparisons between groups were assessed evaluated by Student's t-test, Mann-Whitney, or Chi-square test. The relationship between associated factors and incidence of injuries was estimated by Logistic regression analysis. The model's accuracy was assessed by the receiver-operating characteristic curve (ROC). Thirty-seven runners completed the study. Results: The incidence of injuries was 6.8 per 1,000 hours of exposure. Among the associated factors, we highlight that runners with higher hip flexor force output were 4 times more likely not to injure (OR 4.0; CI 95% 1.03-16.23) and lower knee extensor force output was related to a greater chance of injury (OR .24; 95% CI .65-.93). The area under the ROC curve was 0.84. Conclusion: The incidence of injuries in treadmill runners was high. The factors associated with the injuries were the output of the flexor strength of the hip and the extensor force of the knee.
