Dual-task methodology has been increasingly used to assess cognitive motor interference while walking. However, whether the observed dual-task-related gait changes are systematically related to methodological variations remains unclear and researchers still lack knowledge of what cognitive task to use in different groups for clinical purposes or for(More)
INTRODUCTION Transcranial magnetic stimulation (TMS) is an important tool to examine neurological pathologies, movement disorders, and central nervous system responses to exercise, fatigue, and training. The reliability has not been examined in a functional locomotor knee extensor muscle. METHODS Within- (n = 10) and between-day (n = 16) reliability of(More)
Walking models driven by centre of mass (CoM) data obtained from inertial measurement units (IMU) or optical motion capture systems (OMCS) can be used to objectively measure gait. However current models have only been validated within typical developed adults (TDA). The purpose of this study was to compare the projected CoM movement within Parkinson's(More)
Gait in stroke patients is often characterised by slower speeds, which may be exacerbated by situations that combine gait with a cognitive task, leading to difficulties with everyday activities. Interaction between cognitive task performance and gait speed may differ according to walking intensity. This study examines the effects of two cognitive tasks on(More)
OBJECTIVE To test the effects of feedback of information about patients' asthma to primary care teams. DESIGN Patients' reports of morbidity, use of health services, and drug use on questionnaire was given to primary care teams. Randomised controlled trial with general practices as the subject of the intervention was used to test effectiveness of(More)
Groups of male hamsters of different ages were subjected to a weightlifting exercise regimen of five weeks duration. Transverse fresh frozen sections from the biceps brachii, soleus and extensor digitorum longus (EDL) muscles were incubated for succinic dehydrogenase (SDH) activity. The amounts of Nitro BT diformazan deposited in individual muscle fibres(More)

Erythrocytes from dystrophic hamsters and patients with Duchenne muscular dystrophy were examined for structural changes using light microscopical methods. The effects of specimen preparation were also investigated. The proportions present of echinocytes were significantly greater in dystrophic hamsters and humans when compared with their respective(More)
Pre and perinatal malnutrition of rats was effected by means of limiting the mothers' food intake by 50% during pregnancy and lactation. Male offspring were sacrificed at 36 weeks of age and the anterior tibialis (ANTIB) and soleus (SOL) muscles were prepared for histochemical demonstration of Type I, IIA and IIB muslce fibre types using myosin ATPase and(More)
Groups of male dystrophic hamsters of different ages were subjected to a weightlifting and exercise regimen. Frozen sections from the biceps brachii, soleus and extensor digitorum longus muscles were incubated for succinate dehydrogenase activity. The total amount of Nitro BT diformazan deposited in individual muscle fibres was estimated(More)
