Muscular and neuromuscular control following soccer-specific exercise in male youth: Changes in injury risk mechanisms.

Poor neuromuscular control has been proposed as a risk factor for non-contact injuries, thus this study aimed to explore the effects of soccer-specific fatigue on leg muscle activation, reactive strength, leg stiffness, and functional hamstring/quadriceps ratio (H/QFUNC ) in elite male youth soccer players. Outcome measures were determined in 18 youth players (age 14.4 ± 0.5 years; stature 169.4 ± 9.9 cm; mass 59.3 ± 8.9 kg; maturity offset 0.86 ± 0.88 years) pre and post simulated soccer match play (SAFT90 ). There was no fatigue-related change in the H/QFUNC ; however, reactive strength and leg stiffness were both compromised (P < 0.001) after soccer-specific fatigue. Muscle activation was also locally compromised (P < 0.001) in the medial hamstring and quadriceps but not in the lateral muscles. Where statistically significant changes were observed, the effect sizes ranged from small to large (0.33-0.97). Compromised stiffness when fatigue is present suggests an increased yielding action, greater ground contact times, greater center of mass displacement, and less efficient movement when the limb comes into contact with the ground. This combined with a reduction in medial quadriceps muscle activation may reflect poor kinetic chain control at the hip and an increase in knee injury risk.

A cross-sectional study which measures the prevalence and characteristics of prisoners who report a family history of epilepsy.

Epilepsy is often a familial disorder, although it is not known if relatives of an epileptic proband suffer from any psychological disorders, even without a clinical manifestation of epilepsy. The present study considers this concept in the setting of the largest male prison in Europe, HMP Liverpool. The study formed part of the National Prison Needs Assessment Survey, and consisted of a cross-sectional, questionnaire study. There was a high response rate, and the results indicate that prisoners have a high prevalence of a family history of epilepsy. The study also showed that prisoners who report such a history have significantly more psychological symptoms than those prisoners without such a family history. The conclusion is that the psychological health of relatives of those with epilepsy requires further investigation because the morbidity is higher than expected and may be associated with offending behaviour.

Intermediate care. A suitable case for treatment?

A study of emergency referrals to GPs and hospital accident and emergency departments from nursing homes found that most were appropriate. The most usual reasons for referral were chest infections and changes in medication. Referrals were fewer than five a month per nursing home. Protocols for emergency referrals could improve consistency of care.
