The relationship between retinula and eccentric cells in the lateral eye of Limulus polyphemus was studied using a double electrode technique which permitted simultaneous recording of light-initiated responses in two sense cells and the labeling of the cells for subsequent histological examination and identification. The following results were obtained: (a) light-initiated slow responses with a...

This study investigated the chronology of neural and morphological adaptations to knee extensor eccentric training and their contribution to strength gains in isometric, concentric and eccentric muscle actions. 20 male healthy subjects performed a 12-week eccentric training program on an isokinetic dynamometer, and neuromuscular evaluations of knee extensors were performed every 4 weeks. After ...

BACKGROUND AND AIM Eccentric training has become a popular treatment for patellar tendinopathy. Our purpose was to review the evolution of eccentric strength training programmes for patellar tendinopathy with a focus on the exercise prescriptions used, to help clinicians make appropriate choices and identify areas needing further research. METHODS A computerised search of the entire MEDLINE d...

BACKGROUND Ankle sprain is the most common sports-related injury with a high rate of recurrence and associated costs. Recent studies have emphasised the effectiveness of both neuromuscular training and bracing for the secondary prevention of ankle sprains. AIM To evaluate the effectiveness of combined bracing and neuromuscular training, or bracing alone, against the use of neuromuscular train...

BACKGROUND Corrective bracing for adolescent idiopathic scoliosis (AIS) has favourable outcomes when patients are compliant. However, bracing may be a stressful and traumatic experience and compliance with a bracing protocol is likely to be dependent upon patients' physical, emotional and social wellbeing. The Brace Questionnaire (BrQ), a recently-developed, condition-specific tool to measure q...

BACKGROUND The role of knee bracing in anterior cruciate ligament reconstructions is controversial. HYPOTHESIS Functional bracing will have an effect on subsequent knee injury in skiers with anterior cruciate ligament reconstruction. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS From 1991 to 1997, 11606 skiers at a major destination ski resort underwent preseason knee screening...

AIM Rehabilitation of adolescent idiopathic scoliosis (AIS) requires a careful choice from among the possible treatments, such as bracing and exercises, according to the patient's needs. According to the literature, there is little evidence regarding the efficacy of these rehabilitation instruments. During the past few years, a full series of studies has been carried out to investigate their ef...

Abstract Upon entering the tidal sphere of a supermassive black hole, star is ripped apart by tides and transformed into stream debris. The ultimate fate that debris, properties bright flare produced observed, depends on number parameters, including energy center mass original star. Here we present results set smoothed particle hydrodynamics simulations in which 1 M ⊙ , γ = 5/3 polytrope disrup...
