Objective: Given the prognostic significance of gait speed, there is insufficient evidence about possible functional determinants of gait speed in patients with heart failure with reduced ejection fraction (HFrEF). Therefore, the objective of this study was to investigate the functional determinants of gait speed in patients with HFrEF.
Methods: Fifty-nine patients with HFrEF participated in this cross-sectional study. Demographic and clinical characteristics were recorded. The gait speed was determined with a 4-meter walking test. Dyspnea perception was assessed with the modified medical research council (mMRC) scale. Functional capacity was evaluated with a 6-minute walk test (6MWT). The five times sit-to-stand (5-STS) test and the Berg Balance Scale (BBS) were used to measure functional mobility and balance. Physical activity was evaluated with the International Physical Activity Questionnaire (IPAQ) Short-Form.
Results: Gait speed was correlated with age (r=-0.368, p=0.004), NYHA functional class (r=-0.438, p=0.001), mMRC score (r=-0.422, p=0.001), 6MWT (r=0.650, p<0.001), 5STS (r=-0.506, p<0.001), BBS (r=0.586, p<0.001), IPAQ (r=0.305, p=0.019) and IPAQ-Sitting time (r=-0.327, p=0.011). On multiple linear regression analysis, the 6MWT distance and BBS were independent determinants of the usual gait speed in patients with HFrEF, accounting for 44.4% of the variance.
Conclusion: This study indicates that functional capacity and balance are independent functional determinants of gait speed in patients with HFrEF.

Background: Assessing human movement is essential for diagnosing and monitoring movement-related conditions like neuromuscular disorders. Timed function tests (TFTs) are among the most widespread types of assessments due to their speed and simplicity, but they cannot capture disease-specific movement patterns. Conversely, biomechanical analysis can produce sensitive disease-specific biomarkers, but it is traditionally confined to laboratory settings.

Background: The effect of supplementation of essential amino acids (EAAs) in knee osteoarthritis (OA) remains unclear. This study aimed to evaluate whether supplementation with EAA improves pain, patient-reported outcome measures, gait function, and quadriceps muscle volume in patients undergoing conservative treatment for knee OA.
Methods: A retrospective cohort study was conducted on outpatients undergoing physical therapy from April 2024 to March 2025.

Background: Parkinson's disease (PD) is characterized by motor symptoms altering gait domains such as slow walking speed, reduced step and stride length, and increased double support time. Gait disturbances occur in the early, mild to moderate, and advanced stages of the disease in both backward walking (BW) and forward walking (FW), but are more pronounced in BW. At this point, however, no information is available about BW performance and disease stages specified using the Hoehn and Yahr (H&Y) scale.

Background: While the plantar fat pad is known for its role in shock absorption and plantar force distribution during weight-bearing activities, its impact on running biomechanics is not well understood.
Research Question: Does plantar fat pad thickness affect lower limb biomechanics and plantar pressure distribution during running in healthy adults?
Methods: This cross-sectional observational study involved fourteen participants (18-50 years) who ran at their preferred speed on a 10-meter walkway while lower limb kinematics and ground reaction forces were recorded using a motion capture system. Plantar pressure and force on the right foot were measured using a pressure platform.

Background: Knee osteoarthritis (OA) causes pain and diminishes quality of life. Backward walking exercise (BWE) has been shown to improve lower muscle strength and reduce knee adduction moment, making it a recommended intervention for knee OA rehabilitation. This study aims to evaluate the effectiveness of BWE combined with conventional rehabilitation programs on pain intensity and disability among individuals with knee OA.
