Intra- and inter-rater reliability in ultrasonographic measurements of coracohumeral distance.

Background: Ultrasonography (US) is a widely used diagnostic tool in physical therapy. One of the US variables often utilized to quantify the dimensions of the subacromial space and its association with shoulder pathology is the coracohumeral distance (CHD), however, this measurement presents diverse evidence in terms of reliability.

Objectives: To assess the intra- and inter-rater reliability of both expert and non-expert raters when measuring CHD through US in asymptomatic subjects.

Hypoxic peripheral chemoreflex stimulation-dependent cardiorespiratory coupling is decreased in swimmer athletes.

Swimmer athletes showed a decreased ventilatory response and reduced sympathetic activation during peripheral hypoxic chemoreflex stimulation. Based on these observations, we hypothesized that swimmers develop a diminished cardiorespiratory coupling due to their decreased hypoxic peripheral response. To resolve this hypothesis, we conducted a study using coherence time-varying analysis to assess the cardiorespiratory coupling in swimmer athletes.

Effects of dominance and vision on unipedal balance tests in futsal players using a triaxial accelerometer.

Optimal postural control improves performance and reduces the risk of injury in futsal. In this context, wearable accelerometers may detect velocity changes of the centre of mass during a task, enabling the analysis of postural control in different environments. This work aimed to determine the influence of vision and dominance on unipodal static postural balance in non-professional athletes.

Identifying neuropathies through time series analysis of postural tests.

Background: In physical therapy, postural tests are frequently used to diagnose neuropathies, particularly in diabetic individuals. This study aims to develop a method based on the analysis of time series that allows discriminating between healthy and diabetic subjects with or without a neuropathic condition.

Research Question: Do features obtained from time series corresponding to postural tests allow us to reliably discriminate between healthy, diabetic and neuropathic patients?

Methods: In this study, 32 people participated in the healthy, diabetic, and neuropathic categories (11, 9, and 12, respectively).

Variability in Normalization Methods of Surface Electromyography Signals in Eccentric Hamstring Contraction.

Context: In human movement analysis, normalization of a surface electromyography signal is a crucial step; therefore, parameter selection for this procedure must be adequately justified. The aim of this research was to determine the variability of electromyography signals in eccentric hamstring contraction under different normalization parameters.

Design: Cross-sectional study.

Role of active joint position sense on the upper extremity functional performance tests in college volleyball players.

Background: It has been well established that proprioception plays a decisive role in shoulder stability and sport performance. Notwithstanding, there is a lack of clear association between active joint position sense (AJPS) and the performance of upper-extremity functional performance tests. The aim of this study was to determine whether the AJPS of the shoulder complex is associated with the performance of college volleyball players with the following functional tests: Y-Balance Test-Upper Quarter (YBT-UQ), Closed Kinetic Chain Upper-Extremity Stability Test (CKCUEST), and Seated Medicine Ball Throw (SMBT).

Postural performance assessment in aging people with diabetes and diabetic peripheral neuropathy using a Wii balance board.

Purpose: To determine the effect of sensory perturbations on static postural control in older people with type 2 diabetes mellitus by comparing postural outcomes of people with and without diabetic neuropathy using a Wii Balance Board (WBB).

Materials And Methods: Static postural balance assessments were performed in 31 participants: nine with type 2 diabetes mellitus; 12 with diabetic neuropathy; and 10 non-diabetic controls. Participants stood on the WBB under sensory perturbations (visual and proprioceptive).

Inter-rater reliability of scapular dyskinesis classification in overhead athletes by entry-level physical therapy students.

Background: Scapular dyskinesis (SD) is a dysfunction associated with shoulder pathologies in overhead athletes and its classification is highly complex, especially in entry-level physical therapy students.

Objective: This research aimed to determine the effect of a video training method on inter-rater reliability of physical therapy entry-level students with no clinical experience while performing SD ratings under 4-type, severity, and 'yes or no' criteria in overhead athletes.

Methods: A total of 49 overhead athletes were evaluated by video recordings in posterior view of lifting tasks.

effects of two shoulder girdle motor control exercises on acromiohumeral and coracohumeral distances in healthy men.

Introduction: Altered motor control and proprioceptive deficits are associated with kinematics dysfunctions and may cause alterations in subacromial space (SAS) that could lead to shoulder pathologies. Dimensions of the subacromial space, as well as interventions aimed at its normal restitution, can be explored by ultrasound (US).

Objective: To describe the effect of two shoulder girdle motor control exercises with cognitive training strategies on SAS dimensions, measured with US.

measurements of glenohumeral distraction technique performed in three different joint positions.

: Distraction techniques are an important part of the manual approach in the glenohumeral joint; however, there is controversy regarding the initial joint position to maximize separation of joint surfaces.: To identify, through an exploration, the behavior of the coracohumeral distance (CHD) during the application of a short lever arm grade III distraction technique on the humeral head, executed in three different glenohumeral positions (zero position (P0), rest position (RP) and 90º abduction position with maximum external rotation (ABD+ER)).: 15 participants were selected.
