Review Case ReportsDeep peroneal nerve paresis in a runner caused by ganglion at capitulum peronei. Case report and review of the literature.
Although lateral popliteal sciatic nerve damage is not one of the commonest diseases in the general population, it is quite frequent among athletes. Several physiopathologic mechanisms have been thought to bring about this damage in athletes. Soft tissue ganglions with neurological involvement of the lateral popliteal sciatic nerve or its terminal rami are in differential diagnosis with several lesions of this area, as direct or indirect trauma, subcutaneous rupture of anterior tibialis muscle and long peroneal muscle, disc hernia, intraspinal tumor, anterior tarsal tunnel syndrome, cysts, neurofibroma, baker's cyst, vascular claudication, stenosing or inflammatory pathology of 2(nd) motoneuron, antimicrobial agents for urinary tract infection (nitrofurnantoin). ⋯ The patient underwent surgery to excise the cyst, which led to the rapid resolution of the nerve deficit shown by clinical and electromyographical tests. A meticulous anamnesis and accurate objective examination, followed by specific tests (radiographs, sonography, and possibly CT scan) generally enable a correct diagnosis to be made. If diagnosis and therapy are carried out correctly, and without delay, symptoms quickly resolve and the nerve deficit progressively regresses.

It has been reported that rhythmic gymnasts are at risk of suffering from low back injuries, because of repetitive lumbar hyperextensions. On the other hand, this sport requires features of leanness, muscular strength and flexibility that should represent protective factors for back pain. ⋯ Competitive, club-level rhythmic gymnasts show a reduced prevalence of low back-pain. Being younger in age, having greater leanness, not smoking, displaying less anxious/depressive behaviour, and developing increased muscle strength and flexibility, all can represent preventive factors for low back pain. This study suggests that rhythmic gymnastics is not a discipline at increased risk of low back pain.

Comparative Study Clinical TrialUltrasound changes to intramuscular architecture of the quadriceps following intramedullary nailing.
Disuse atrophy is the basis for profound physiological changes of the muscles of immobilised limbs. The aim of this study was to use high resolution real-time ultrasonography (HRRTU) to assess the quadriceps musculature and to try and measure atrophy. ⋯ These simple, reproducible, non-invasive ultrasound measurements can easily demonstrate differences in the quadriceps morphology in the nailed and unnailed limb, which could allow individual exercise programme prescription.

Soccer reportedly places participants at risk for neuropsychological impairment, although it is unknown if the risk is associated primarily with concussion, subconcussive blows from heading the ball, or some combination thereof. Moreover, the extent to which younger versus older athletes are at risk for soccer-related cognitive impairment is unclear. We hypothesized that soccer athletes, especially older ones, would show poorer neuropsychological test performance than comparable swimmers. ⋯ Results provide additional evidence that participation in soccer may be associated with poorer neuropsychological performance, although the observed pattern of findings does not specifically implicate heading as the cause. Although deficits were most apparent among older soccer players, serial neuropsychological testing for early detection of impairment is recommended for younger players as well.

The benefits of aerobic dance toward the contribution to overall wellness have been studied in a skewed manner. Numerous studies in the past have examined the cardiorespiratory benefits of aerobic dance. Fewer studies have reported the effects on agility, flexibility and coordination. Moreover even fewer studies have used aerobic dance instructors as subjects. ⋯ On the basis of the present data we conclude that extended participation in aerobic dance does not contribute to better sit and reach flexibility, trunk flexibility, dynamic rotational flexibility or agility and that aerobic dance teachers should participate in general flexibility stretching activities and secondary activities to improve and/or maintain agility and general coordination.
