To determine the incidence and nature of injuries sustained by elite cricketers during a four-season period in order to identify the evidence of any injury patterns associated with these injuries. Thirty-eight physiotherapists and 14 doctors working with 11 provincial teams and the South African national team completed a questionnaire for each cricketer who presented with an injury during each season.
The objective is to determine the effects of strapping the tendo-Achilles (t-A) on soleus and gastrocnemius electromyographic activities and postural sway. A pre-test, post-test experimental design was used. Ten male university students (mean age 24 years) participated by voluntary consent. Data collection in the physiotherapy research laboratory at the University of Durban-Westville ensured that electromyographic signals were minimally contaminated. Soleus and gastrocnemius electromyographic activities were recorded using 8 mm silver/silver chloride (Ag/AgCI) surface electrodes connected to the Biopac electromyographic (EMG) system.
The International Olympic Committee (IOC) has ruled that 19-norandrosterone should be quantified if present in low concentrations in urine of sport competitors. The question, however, is how stable is 19-norandrosterone in urine. In the light of this IOC ruling it is therefore important to know if the concentration of 19-norandrosterone can change during the transportation process of urine samples to the laboratory or during the handling and storage of the samples in the laboratory.
Avulsion fractures of the pelvis occur predominantly in adolescent athletes. This article reviews the different types of avulsion fractures, their clinical presentation, special investigations in aid of a diagnosis, as well as the treatment of these fractures. It is important for doctors, coaches and the rest of the medical team to understand and treat these injuries correctly.
