Immediate Effects of Calf Tissue Flossing on Ankle Joint Torque and Dorsiflexion Range of Motion in Healthy Individuals: A Randomized Controlled Crossover Trial.

Tissue flossing involves wrapping a rubber band around a muscle group for a few minutes while performing joint motion, enhancing ankle joint torque and range of motion. As limited ankle dorsiflexion range of motion and plantar flexion muscle weakness are risk factors for sports injury, assessing the therapeutic effects of tissue flossing is important. This study aimed to evaluate the immediate effects of calf tissue flossing on enhancing ankle joint torque and dorsiflexion range of motion.

Clinical Outcomes and Return to Play in Dynamic Anterior Glenohumeral Capsular Ligament Tensioning Procedure for Overhead-throwing Athletes with Traumatic Shoulder Dislocation on the Throwing Side.

Background: Although arthroscopic Bankart repair for shoulder instability after a traumatic shoulder dislocation is a standard procedure, return-to-play rates for overhead-throwing athletes with shoulder instability on the throwing side have been reported to be lower than those in non-overhead athletes or in non-throwing shoulders. A recent technical report showed that the dynamic anterior glenohumeral capsular ligament tensioning (DAGHT) procedure in abducted external rotation, which mimics the late cocking phase of the throwing motion during surgery, may provide optimal tensioning of the anterior glenohumeral ligament. This study compared clinical outcomes and return to play after arthroscopic Bankart repair between DAGHT and a conventional procedure for overhead-throwing athletes with traumatic dislocation on the throwing side.

Clinical characteristics and results after conservative treatment or interfascicular neurolysis of 100 limbs with spontaneous anterior interosseous nerve palsy: A prospective Japanese multicenter study.

Background: Spontaneous anterior interosseous nerve (AIN) palsy is characterized by the sudden onset of upper limb pain followed by weakness of muscles mainly innervated by the AIN. Although this palsy is conventionally treated conservatively, interfascicular neurolysis to release hourglass-like fascicular constrictions has been recommended. The present study aimed to establish the clinical characteristics and treatment strategy for this condition.

Dynamic Anterior Glenohumeral Capsular Ligament Tensioning During Arthroscopic Shoulder Stabilization in Overhead-Throwing Athletes.

Although the most common surgical treatment for traumatic anterior shoulder instability is arthroscopic Bankart repair (ABR), which has shown good postoperative results, a potential risk of postoperative external rotation deficit exists. For overhead-throwing athletes, recovery of postoperative range of motion during abduction and external rotation is essential to return to preinjury performance levels. We consider that the key to returning to play after ABR on the dominant side in overhead-throwing athletes is to simultaneously gain anterior stability and mobility of the shoulder.
