Article Abstract
Purpose: Scapular protraction strength can be evaluated using a hand-held dynamometer (HHD). However, it is necessary to measure the reliability of HHD in individuals with shoulder pain and to minimize the limitations related to the evaluator and the low methodological quality cited in previous studies. This study assessed, with methodological enhancement, the intra- and interrater reliability of belt-stabilized HHD in the assessment of scapular protraction strength in individuals with shoulder pain.
Method: Fifty individuals with unilateral symptoms of subacromial pain syndrome (20 men, aged 40.5 ± 15.3 years) were evaluated in two sessions using the belt-stabilized HHD for maximum isometric strength of scapular protraction with the individual in the sitting and supine positions. Reliability values were obtained using the intraclass correlation coefficient with the standard error of measurement (SEM and %SEM) and the minimal detectable change (MDC).
Results: The intra- and interrater HHD reliability were excellent for all measurements ranging from 0.88 to 0.96 (SEM = 2.0-4.0 kg; %SEM 12 to 17; MDC = 6-11 kg).
Conclusion: Belt-stabilized HHD is reliable for the assessment of scapular protraction strength in individuals with subacromial pain syndrome in both the sitting and supine positions.

Biscapular Protraction Force and Excursion in Adult Patients With Traumatic Brachial Plexus Injuries: A Comparative Study.

Purpose: Traditional body-powered upper limb prostheses use a Bowden cable to translate shoulder and residual upper limb movements into forces that control the terminal device. The necessary force and excursion required to use a traditional body-powered prosthesis in patients with traumatic brachial plexus injuries (BPI) has yet to be ascertained. This study compared the force and excursion generated during biscapular protraction in adults with traumatic BPI compared to healthy volunteers.

Background: Acromioclavicular joint (ACJ) dislocations have been linked to altered scapulothoracic orientation and scapula dyskinesis, but research on three-dimensional (3D) changes in scapulothoracic orientation after such injury in vivo has not been described before. The aim of our pilot study was to analyze scapulothoracic orientation changes in patients with ACJ dislocations using three-dimensional computed tomographic (CT) image reconstruction.
Methods: Patients with ACJ dislocations who underwent CT imaging were included retrospectively and consecutively.
Impact of scapula anatomical landmark positioning on scapular orientation using CT-based 3-dimensional models: an intraobserver repeatability and interobserver reproducibility study.

Hypothesis: The primary objective of this study was to assess intraobserver repeatability and interobserver reproducibility of the 3-dimensional (3D) coordinates of a set of scapula anatomical landmarks obtained by manual positioning on conventional supine computed tomography (CT) scan-based scapula surface models. The secondary objective was to assess intraobserver repeatability and interobserver reproducibility of the resulting 3D scapular orientation. It was hypothesized that the 3D scapular orientation reliability would be better or similar than established reliability of intraoperative baseplate positioning (ie, version and inclination) in reverse total shoulder arthroplasty.

: Many patients evaluated by shoulder specialists suffer from intractable pain, neuropathy, and weakness. The pectoralis minor (PM) remains the only scapula muscle to receive lower trunk (C8-T1) input. We propose a novel syndrome: the Human Disharmony Loop.

Cerebellar ataxia is characterized by a variety of motor and non-motor manifestations. This case report aims to present a case of cerebellar ataxia secondary to cerebellar infarct and the pivotal role of physiotherapy in gaining patients' functional recovery, thereby improving their dynamic trunk balance and quality of life. We glance at the case of a 50-year-old man, complaining of bilateral upper and lower limb weakness with clumsy balance while sitting and walking.
