Neglected Achilles Tendon Ruptures are commonly seen by orthopaedic surgeons. In cases resistant to conservative treatment, a variety of surgical procedures have been utilized in the past. The senior -surgeon at our institution has utilized a technique -employing two turndown fascia flaps fashioned from the proximal Achilles tendon augmented by a tenomyodesis of the flexor hallucis longus and p...

BACKGROUND Analysis of electromyographic (EMG) activities in the back during dynamic exercise is needed because more complex loading on the spine is created in comparison with that during static exercise. The purpose of this study is to investigate the difference in bilateral midback and low-back paraspinal muscle (PSM) activities during performance of different resistance isokinetic exercises ...

This study proposes a method for estimating force loss during fatiguing maximal isokinetic knee extension contractions using a set of features from surface EMG signals recorded from multiple locations over the quadriceps muscle. Nine healthy participants performed fatiguing tests which consisted of 50 and 75 isokinetic leg extensions at a speed of 30 degrees /s and 80 degrees /s in two experime...

BACKGROUND The free fibula flap has become popular for mandibular reconstruction. The purpose of this study was to propose comprehensive functional assessments of the donor site. METHODS Thirty free fibula flaps for mandible reconstruction were prospectively enrolled in the study. Objective assessments included isokinetic testing of the ankle joint, electromyographic examination of the superf...

Few studies have investigated peripheral muscle strength and quality in patients with cystic fibrosis (CF). The present study tested the isometric and isokinetic strength of the quadriceps and hamstrings using an isokinetic dynamometer and a strength-testing chair in 25 CF adults and 25 controls. Total body and leg muscle mass were determined by dual-energy X-ray absorptiometry, and bone minera...

The isokinetic strength of the elbow and knee extensors and flexors was measured in 200 healthy 45- to 78-yr-old men and women to examine the relationship between muscle strength, age, and body composition. Peak torque was measured at 60 and 240 degrees/s in the knee and at 60 and 180 degrees/s in the elbow by use of a Cybex II isokinetic dynamometer. Fat-free mass (FFM) was estimated by hydros...

Background Recent evidence shows a delayed return to sport in children and delayed quadriceps recovery in both adults and children who have undergone anterior cruciate ligament (ACL) reconstruction with concomitant femoral nerve blockade (FNB) compared with those who had no blockade. We evaluated the use of adductor canal blockade (ACB), as an alternative to FNB, at the time of ACL reconstructi...

The importance of the menisci for transmitting workloads in the knee joint to protect the articular cartilage is widely acknowledged. Therefore various techniques have been introduced to repair the damaged meniscus.We performed an arthroscopic meniscus repair with a modified outside-in technique on 29 patients (average 25 years) between 2/91 and 10/94. The average time between trauma and operat...

CONTEXT There is limited information on fatigue of the evertors on frontal plane joint position sense (JPS). OBJECTIVE To examine the effects of isokinetic concentric-eccentric fatigue of the evertors on frontal plane JPS of the ankle. DESIGN A2 x 4 factorial design. SETTING Research Laboratory. PATIENTS OR OTHER PARTICIPANTS 40 male and female healthy subjects. INTERVENTIONS JPS was ...
