'Summer of Sport': the development of a 6-week programme in increasing physical activity to improve public health outcomes.

OBJECTIVES: A population-based physical activity (PA) programme was implemented to increase PA levels and encourage individuals to join the local council leisure facility. STUDY DESIGN: This is a cross-sectional design. METHODS: The 6-week programme Summer of Sport (SOS) involved a total of 487 individuals registered for PA sessions. The sessions were held at three local council leisure facilities included badminton, swimming, table tennis, squash and group cycle. The programme was assessed using a survey based on the Theory of Planned Behaviour. Individuals were asked for their current fitness levels, whether the programme encouraged them to be more active and for their intentions to join the leisure centre after the programme. RESULTS: Of the 487 who originally registered for the programme, there were 161 users of SOS, with 112 not already members of the leisure facility. After the programme, 83% considered themselves already being active, with 78% stating that they partook in at least 30 min of exercise, 3 times per week. Although a large proportion of individuals were already physically active, 78% stated that taking part encouraged them to become more active. More than half suggested that they would not join the leisure facility, 30% said that they had joined after the programme and 17% stated their intention to join. Many individuals highlighted that the programme provided an opportunity to be active with their family. CONCLUSIONS: Public health teams should work with partner organisations to embed robust processes for measuring outcomes that impact on population health.

The neural representation of language in users of American Sign Language.

UNLABELLED: Studies of American Sign Language (ASL) offer unique insights into the fundamental properties of human language. Neurolinguistic studies explore the effects of left and right hemisphere lesions on the production and comprehension of signed language. Following damage to the left hemisphere perisylvian regions, signers, like users of spoken languages, exhibit frank aphasic disturbances. Sign language paraphasia illustrates the linguistic specificity of impairment. A case study involving cortical stimulation mapping (CSM) in a deaf signer provides evidence for the specialization of Broca's area in sign language production. The effects of right hemisphere damage highlight the specialized properties of sign language use. Data from functional magnetic resonance imaging (fMRI) of deaf signers confirm the importance of left hemisphere language structures in the use of signed language, but also reveal the contributions of right hemisphere regions to the processing of ASL. These studies provide new insights into the complementary roles of biology and environment in language representation in the human brain. LEARNING OUTCOMES: As a result of this activity, the participant will read studies of aphasia in users of signed language and a discussion of neurolinguistic studies of paraphasia in ASL. The participant will examine the role of the right hemisphere in language use and findings from a functional imaging study of sentence processing in ASL and English.

Functional roles of Broca's area and SMG: evidence from cortical stimulation mapping in a deaf signer.

The importance of the left hemisphere in language function has been firmly established and current work strives to understand regional specializations within the perisylvian language areas. This paper reports a case study of a deaf user of American Sign Language undergoing an awake cortical stimulation mapping procedure. Patterns of sign errors accompanying electrical stimulation of Broca's area and the supramarginal gyrus (SMG) are reported. Our findings show Broca's area to be involved in the motor execution of sign language. These data demonstrate that the linguistic specificity of Broca's area is not limited to speech behavior. In addition, unusual semantic-phonological errors were observed with stimulation to the SMG; these data may implicate the SMG in the binding of linguistic features in the service of language production. Taken together, these findings provide important insight into the linguistic specificity of Broca's area and the functional role of the supramarginal gyrus in language processing.
