[Purpose] The aim of this study was to assess the medical complications in first-time ischemic stroke patients, to identify the factors related to occurrence of complications. [Subjects and Methods] First-time ischemic stroke patients (n=81) admitted to a tertiary level inpatient rehabilitation center during a 5 year period were included in the study. The attending physiatrist noted the presence of specific medical complications and complications that required transfer to the acute care facility from patient records. The Oxfordshire Community Stroke Project classification was used to define the clinical subtypes of the ischemic stroke patients. The Charlson comorbidity index was used to evaluate co-morbid conditions. Functional disability was assessed using the Functional Independence Measure at admission and discharge. [Results] We found that 88.9% of the patients had at least one complication. The five most common complications were urinary tract infection (48.1%), shoulder pain (37.0%), insomnia (37.0%), depression (32.1%), and musculoskeletal pain other than shoulder pain (32.1%) and 11.1% of patients were transferred to acute care facility during rehabilitation period. Functional Independence Measure scores both at admission and discharge were significantly lower in patients with at least one complication than in patients with no complications. [Conclusion] Medical complications are common among patients undergoing stroke rehabilitation. Close interdisciplinary collaboration between physiatrists and other medical specialities is necessary for optimal management.

“…Previous studies have shown that shoulder joint positions could affect muscle activation 25 , 26 , 27 ) around the shoulder and the shoulder’s rotational strength 14 , 15 , 18 ) . The present study also found that the ER and IR strengths of the shoulder changed with the shoulder abduction angles in the scapular plane.…”

[Purpose] This study aimed to investigate the effect of shoulder positions and speeds on internal and external rotation torque of college baseball players and age-matched non-players. [Subjects] Twenty first-level collegiate baseball players and 19 college students were recruited. [Methods] A dynamometer system was used to evaluate the shoulder rotation strength in sitting postures. Three testing positions, namely shoulder abduction of 45°, 70°, and 90° in the scapular plane, were combined with three testing speeds at 60°/s, 120°/s, and 210°/s. [Results] The maximum external and internal rotation torques both occurred at shoulder abduction of 70°. However, only external rotation torque was affected by the speed, with the peak value observed at 60°/s. The internal rotation torque of baseball players was larger than that of the control group under all testing conditions, but the external rotation did not show any difference. The ratio of external to internal rotation torque changed with the testing positions and speeds in both groups. The ratio in the control group was greater than that in the player group. [Conclusion] The shoulder position could affect the rotational strength, and the baseball players could strengthen their external rotators for better performance and injury prevention.

“…The functional length of the SA can change the contraction distance of the muscle, which affects muscle activity. Researchers 16,[31][32][33][34] have examined muscle activity using different hand orientations and at shoulder-flexion angles of 1108, 908, and 708 during the PUP exercise. Lee et al 16 reported larger SA EMG activity during the PUP exercise with the shoulder externally rotated than with it in neutral or internally rotated.…”

Context Whereas the serratus anterior (SA) and the upper trapezius (UT) work as a force couple for scapular motion, weakness of the SA and overactivation of the UT are often present in overhead athletes with shoulder dysfunction. Therefore, researchers addressing an intramuscular imbalance between the SA and UT have focused on finding exercises that target the weak SA and minimally activate the UT. Objective To compare the effectiveness of push-up plus (PUP) exercise variants based on the electromyographic (EMG) activity of the SA and UT. Data Sources A systematic search of PubMed and Scopus between January 1, 2000, and March 31, 2008. Study Selection Studies of PUP exercises that involved EMG analysis. Data Extraction We assessed study quality using the Critical Appraisal Skills Program. For the systematic analysis, the following data were extracted: (1) author, year, and study design; (2) participant characteristics; (3) type of PUP intervention; (4) EMG outcome measures; and (5) main results. For the meta-analysis, the EMG data of the SA and UT were calculated using the mean difference of EMG activity with a 95% confidence interval. Data Synthesis Based on 19 studies with 356 participants, different hand positions (the distance between the hands, shoulder-flexion angle, and elbow-flexion angle) and different lower extremity positions variably affected the activation of the SA and UT during the PUP exercise. Also, when participants performed the PUP on an unstable surface compared with a stable surface, UT activity increased 2.74% (95% confidence interval = 0.07%, 5.41%). Conclusions The standard PUP exercise elicited high EMG activity of the SA. Participants generated higher SA and lower UT EMG activity when they performed the PUP exercise on a stable surface in full elbow extension, with the hands placed shoulder-width apart, shoulder-flexion angles of 110° or 120°, and the ipsilateral lower extremity lifted.
