Hip passive stiffness is associated with hip kinematics during single-leg squat.

Introduction: Single-leg squat (SLS) is a test commonly used to assess lower limb function in rehabilitation. Increased hip adduction and internal rotation (IR) is associated with dynamic knee valgus, which is related to hip and knee overload. Proximal and distal factors, such as hip passive stiffness, poor hip muscle strength and excessive foot misalignment may influence hip movement.

Correlation between goniometric and photogrammetric assessment of shank-forefoot alignment in athletes.

Background: The shank-forefoot alignment (SFA) measurement has been previously developed to enhance the applicability of foot alignment measurement in sports preseason assessment because it is reliable and less time consuming. The use of SFA measurements in the clinical context, usually done with photogrammetry, may be simplified by using the universal goniometer and no longer requiring the image processing step that takes additional time and equipment.

Objective: Investigate the correlation between the goniometric and photogrammetric assessment of shank-forefoot alignment in athletes.

Correlation between indexes of autonomic maneuvers and heart rate variability in hemodialysis patients.

Purpose: The autonomic maneuvers are simple methods to evaluate autonomic balance, but the association between autonomic maneuvers and heart rate variability (HRV) in hemodialysis patients remains unknown. This study aimed to evaluate the correlation between HRV and respiratory sinus arrhythmia (RSA) and Valsalva maneuver (VM) indexes in hemodialysis patients and to compare two methods for RSA indexes acquisitions.

Methods: Forty-eight volunteers on hemodialysis (66.
