Objective. To compare effects of ultrasound- (US-) guided percutaneous electrolysis combined with an eccentric exercise program of the rotator cuff muscles in subacromial pain syndrome. Methods. Thirty-six patients were randomized and assigned into US-guided percutaneous electrolysis (n = 17) group or exercise (n = 19) group. Patients were asked to perform an eccentric exercise program of the r...

The purpose of this study was to compare kinematics and muscle activity between chin-ups and lat-pull down exercises and between muscle groups during the two exercises. Normalized electromyography (EMG) of biceps brachii (BB), triceps brachii (TB), pectoralis major (PM), latissimus dorsi (LD), rectus abdominus (RA), and erector spinae (ES) and kinematics of back, shoulder, and seventh cervical ...

purpose there is a decrease in quadriceps muscle strength in subjects with patellofemoral pain syndrome. various types of strengthening exercises of the quadriceps are done as part of its management, but the effect of isotonic eccentric quadriceps muscle exercises on patellofemoral pain syndrome has not been studied. hence the aim of this exploratory pilot study was to evaluate the effect of ec...

This study aimed to compare the effects of different velocities of eccentric muscle actions on acute blood lactate and serum growth hormone (GH) concentrations following free weight bench press exercises performed by resistance-trained men. Sixteen healthy men were divided into two groups: slow eccentric velocity (SEV; n = 8) and fast eccentric velocity (FEV; n = 8). Both groups performed four ...

Purpose: Many patients with Achilles Tendinopathy do not respond to eccentric training. The aim of the present case report is to find out the effect of eccentric concentric training of gastrocnemius and soleus combined with isometric contraction of gastrocnemius and static stretching exercises of gastrocnemius and soleus on pain and disability in a patient experiencing Achilles Tendinopathy. Me...

Background: The amount of anterior tibial translation during rehabilitation exercises is a key factor in organizing exercise regimen after anterior cruciate ligament injury. Excessive anterior tibial translation could increase the magnitude of tension imposed on injured and reconstructed anterior cruciate ligament knees. Forward lunge and open-kinetic knee extension exercises are commonly used ...

Background and Objectives: The aim of the present study was to investigate effectsof a single sessionof eccentric or concentric resistance exercise on relative expression of BDNF, PAX7 and IGF-1 in healthy participants. Materials and Methods: In a field trial, ten healthy young men were randomly assigned into two equal groupsof concentric and eccentric contractions. Isokinetic contraction prot...

Most common preventive eccentric-based exercises, such as Nordic hamstring do not include any hip flexion. So, the elongation stress reached is lower than during the late swing phase of sprinting. The aim of this study was to assess the evolution of hamstring architectural (fascicle length and pennation angle) and functional (concentric and eccentric optimum angles and concentric and eccentric ...

Objective To evaluate if a specific exercise strategy, targeting the rotator cuff and scapula stabilisers, improves shoulder function and pain more than unspecific exercises in patients with subacromial impingement syndrome, thereby decreasing the need for arthroscopic subacromial decompression. DesignRandomised, participant and single assessor blinded, controlled study. Setting Department of o...
