BACKGROUND Resistive exercise after stroke can improve strength (force-generating capacity) without increasing spasticity (velocity-dependent hypertonicity). However, the effect of resistive load type on muscle activation and co-contraction after stroke is not clear. OBJECTIVE The purpose of this study was to determine the effect of load type (elastic, viscous, or mass) on muscle activation a...

Background. Kinesiotape (K-tape) application can attenuate postural malalignment. However, the effects of K-tape on the changes in the respiratory system in postural problems remain unclear. Objectives. This study investigated the effects of 6-week functional correction with the K-tape on the forward shoulder posture (FSP) and respiratory function. Methods. A randomized clinical trial was per...

This article describes the case of a 77-year-old man with a recurrent posterior shoulder dislocation, treated with humeral hemiarthroplasty and reconstruction of a large posteroinferior glenoid defect with a bone block created from humeral head autograft. On examination, the patient's left arm was held in internal rotation against his stomach, with minimal swelling about the deltoid. His should...

OBJECTIVE The primary goal of this study was to test the hypothesis that wearing the 3.7 kg vest portion of a radiological shielding garment (a "lead") significantly increases lower back and shoulder muscle activity in quasistatic erect and forward-flexed postures. Secondarily, the authors examined the effects of gender and forward-flexed posture as well as their interactions with lead use. B...

OBJECTIVE The Lower Anchor and Tethers for CHildren (LATCH) system was introduced in vehicles made after September 1, 2002 and intended to make installation of rear and forward-facing child safety seats easier. Due to the lack of rear impact testing of RFCRS required per the Federal Motor Vehicle Safety Standards (FMVSS), the purpose of this study was to explore the effects, if any, of installa...

BACKGROUND Suprascapular nerve entrapment with isolated paralysis of the infraspinatus muscle is uncommon. However, this pathology has been reported in volleyball players. Despite a lack of scientific evidence, excessive strain on the nerve is often cited as a possible cause of this syndrome. Previous research has shown a close association between shoulder range of motion and strain on the supr...

Although it is commonly accepted that there is an interrelationship between the temporomandibular joint (TMJ) and head posture, few, if any, previous studies have quantified this effect. The purpose of this study is to quantify the effect of a change in the condyle fossa relationship of symptomatic temporomandibular joints on head posture. Charts of 51 patients (N=10 men and N=41 women) with sy...

Treatment of patients with rotator cuff deficiency and arthritis in the setting of a prior glenohumeral infection (postinfectious arthropathy) is complex, with little evidence to guide treatment. The current authors present their approach to management of these patients and clinical outcomes after reverse shoulder arthroplasty (RSA). All primary RSAs performed for postinfectious arthropathy and...

Some patients with rotator cuff tear have shoulder stiffness preoperatively. Concomitant preoperative shoulder stiffness may affect postoperative outcomes of arthroscopic subacromial decompression (ASD) for rotator cuff tear. The purpose of this study was to compare postoperative outcomes for ASD between rotator cuff tear patients with and without preoperative shoulder stiffness and to analyze ...
