OBJECTIVE: There are extremely limited data on minority populations, especially Hispanics, describing the clinical epidemiology of acute coronary disease. The aim of this study is to examine the incidence rate of acute myocardial infarction (AMI), in-hospital case-fatality rate (CFR), and management practices among residents of greater San Juan (Puerto Rico) who were hospitalized with an initial AMI. METHODS: Our trained study staff reviewed and independently validated the medical records of patients who had been hospitalized with possible AMI at any of the twelve hospitals located in greater San Juan during calendar year 2007. RESULTS: The incidence rate (# per 100,000 …

Feedback Regulation Of Temporal Muscle Activation Patterns For Postural Control Before And After Peripheral Neuropathy, L Ting, D Lockhart, P Stapley, J Macpherson
Dr Paul J Stapley
Introduction: Neural mechanislllS determining temporal pattcl1ls of muscle activity during poshlral responses are not understood. Fulluwing pyridoxine inuuced somatosensory loss in cats, unset latencies of automatic poshu-al responses are delayed, and balance is impaired. We introduce a new method for correlating temporal patterns of muscle activation with task-level variahles in the context of postural responses to perturbation. Methods: We measured postmal responses to support smface tronslations before and after loss of group I afferents indnced by pyridoxine intoxication. We reconstructed temporal EMG patterns llsing a feedback loop with delays, on CoM acceleration. velocity, and displacement. Resnlts: Prior to lesion, temporal …
Neck Muscle Fatigue And Postural Control In Patients With Whiplash Injury, Paul Stapley, Maria Beretta, Elena Toffola, Marco Schieppati
Neck Muscle Fatigue And Postural Control In Patients With Whiplash Injury, Paul Stapley, Maria Beretta, Elena Toffola, Marco Schieppati
Dr Paul J Stapley
Objectives: To examine if patients with whiplash injury show identifiable increases in neck muscle fatigability and associated increase in postural body sway after contractions of dorsal neck muscles, and if physiotherapy treatment reduces these effects. Methods: Sway was measured during stance in 13 patients before and after 5 min of isometric dorsal neck muscle contractions and after recovery, pre- and post-physiotherapy, using a force platform. Amplitude and median frequency of neck muscle EMG were calculated during the contracting period. After each stance trial, patients gave a subjective score of sway. Results: Pre-treatment, seven patients showed EMG signs of fatigue (increases …

A Common Neural Substrate For The Control Of Anticipatory And Compensatory Postural Responses, Paul Stapley, Benedicte Schepens, Trevor Drew
Dr Paul J Stapley
We have shown previously that reticulospinal neurones (RSNs) in the brainstem pontomedullary reticular formation (PMRF) contribute to the production of the anticipatory postural adjustments (APAs) that precede reaching movements executed in a standing pOSition (Schepens and Drew, 2004, 2006; Schepens, Stapley and Drew, 2008). More recently (Stapley and Drew, 2009), we have also shown that cells in the PMRF contribute to the production of the compensatory responses that are produced by unexpected perturbations (drops) of the support surface from under one paw during quiet stance. In this poster we address the question of whether the same cells in the PMRF …
Posture Control During Online Corrections Of Arm Movements Is Predictive, Julia Leonard, Paul Stapley
Posture Control During Online Corrections Of Arm Movements Is Predictive, Julia Leonard, Paul Stapley
Dr Paul J Stapley
The control of reaching to a target in standing involves the feed-forward programming of associated postural adjustments (a PAs) that decelerate the body and arm toward the target (Leonard et ai, 2009). However, little is known about the control of aPAs in situations where the final position of the target goal shifts after the reach movement has been initiated. We hypothesized that a predictive reprogramming of the aPA would occur prior to the adjustment of the arm movement to ensure correct execution of the reaching movement. Using a double step paradigm, we investigated the postural adjustments in standing humans exposed …
Independent Control Of Limb Force Underlies Stability During Voluntary Head Movements In Standing Humans, Paul Stapley, Alicia Hilderley, Julia Leonard
Independent Control Of Limb Force Underlies Stability During Voluntary Head Movements In Standing Humans, Paul Stapley, Alicia Hilderley, Julia Leonard
Dr Paul J Stapley
Postural stability during voluntary head movements is maintained through the integration of vestibular and neck afferent inputs. These inputs combine to accurately estimate trunk position in space, relative to a turning head. In animals, a loss of vestibular information leads to an active destabilization of balance as neck afferent information is interpreted as a movement of the trunk under a stable head (Stapley et al. 2006).
Neuromuscular Control And Exercise-Related Leg Pain In Triathletes, Andrew Chapman, Paul Hodges, Andrew Briggs, Paul Stapley, Bill Vicenzino
Neuromuscular Control And Exercise-Related Leg Pain In Triathletes, Andrew Chapman, Paul Hodges, Andrew Briggs, Paul Stapley, Bill Vicenzino
Dr Paul J Stapley
Previous studies have shown that cycling can directly influence neuromuscular control during subsequent running in some highly trained triathletes. A relationship between this altered neuromuscular control of running and musculoskeletal pain and injury has been proposed; however, this link has not been investigated. PURPOSE: This study aimed to evaluate the influence of cycling on neuromuscular control during subsequent running in highly trained triathletes with and without exercise-related leg pain (ERLP). METHODS: Participants were 34 highly trained triathletes: 10 triathletes with a history of ERLP and 24 training-matched control triathletes with no history of ERLP. Knee and ankle kinematics and leg …

Involving Providers And Patients In Cancer Control And Prevention Efforts. Barriers To Overcome, Donald Iverson
Involving Providers And Patients In Cancer Control And Prevention Efforts. Barriers To Overcome, Donald Iverson
Don C. Iverson
Although progress has been made in providing cancer prevention and control services to the population, there remain sizeable segments of the population that are either uninvolved or underinvolved with national and state efforts. One method of reaching most of the population, including those segments currently not involved or underinvolved, is through primary care clinicians. Effective, albeit imperfect, strategies to increase the involvement of primary care clinicians in cancer prevention and control are available, and there is emerging evidence that these strategies are making a difference. Unfortunately, the progress made to date is at risk of being lost because of economic …

Don C. Iverson
"This paper examined whether work-to-family interference (WFI) and work-to-family enhancement (WFE) mediated the association between job demands/control and self-reported mental and physical health. Data were from the Household, Income and Labor Dynamics in Australia survey and included 1,404 Australian adults aged 18-64 years at baseline; 820 participants provided data at three time points (baseline, 12-month follow-up, and 24-month follow-up). Self-report questionnaires assessed mental and physical health, WFI and WFE, and job demands/control. Mediation analyzes performed on the longitudinal data indicated that WFI mediated the relationships between job demands/control and self-reported mental and physical health. The findings have implications for improving …
