The effect of internal and external visualization of rotation on postural stability

Frontiers in Cognition
IntroductionDuring mental rotation tasks, it is assumed that participants visualize a rotation of objects in their minds (internal visualization), but mental rotation has also been linked to the visible rotation of objects on a screen (external ...

Shoulder Magnetic Resonance Arthrography with the Internal and External Rotation Positions of the Humeral Head in the Evaluation of SLAP Lesions

Diagnostics, 2022
We aimed to evaluate the diagnostic performance of shoulder MR arthrography (MRA) acquired in the neutral (N), internal rotation (IR), and external rotation (ER) positions of the shoulder to detect SLAP lesions.

Clinical results of reverse shoulder arthroplasty for comminuted proximal humerus fractures in elderly patients: a comparison between nonporous stems versus trabecular metal stems

JSES International, 2020
Background: This study compared the clinical results for nonporous stems vs. trabecular metal (TM) stems used in reverse shoulder arthroplasty (RSA) for comminuted proximal humeral fractures (CPHFs) in elderly patients.

Moderate External Rotation of Tibial Component Generates More Natural Kinematics Than Internal Rotation After Total Knee Arthroplasty

Frontiers in Bioengineering and Biotechnology, 2022
This study aimed to investigate the influence of tibial malrotation on knee kinematics after total knee arthroplasty (TKA). A symmetric fixed-bearing posterior-stabilized prosthesis was implanted in the validated knee model with different rotational ...

Is subscapularis repair correlated with better outcome compared to non-repair in reverse total shoulder arthroplasty? A systematic review of comparative trials

Orthopedic Reviews, 2019
We aimed to investigate whether combined reverse total shoulder arthroplasty (RTSA) and subscapularis repair leads to improved clinical and functional outcome in comparison with RTSA alone.

In‐vivo assessment of meniscal movement in the knee joint during internal and external rotation under load

Journal of Experimental Orthopaedics, 2022
Purpose The menisci transmit load between femur and tibia and thus play a crucial role in the functionality of the knee joint. Knee joint movements have a major impact on the position of the menisci.

Investigation of effective standing posture for increasing activity of pelvic floor muscles: a cross-sectional study

Journal of Physical Fitness and Sports Medicine, 2023
Pelvic floor muscle (PFM) exercises have been shown to strengthen PFM function and improve urinary incontinence (UI) symptoms. Several studies have focused on voluntary PFM activity changes among various supine postures.

Limitation of the external glenohumeral joint rotation is associated with subacromial impingement syndrome, especially pain

JSES International, 2021
Background: Subacromial impingement syndrome is a common disorder associated with functional impairment and disability of the shoulder. Internal/external glenohumeral rotation is important for shoulder function.
