Objective: Traditional measures of cognitive abilities most used by neuropsychologists are generally low in ecological validity and only capture a small proportion of the variance of a person's true functional capacity. This study evaluates the association between clinic-based performance and parallel real-world completion of an everyday planning test, the Overnight Trip Task (OTT).

Method: A cross-sectional cohort of 65 community-dwelling older adults completed a battery of cognitive assessments and two formats of the OTT: the paper-and-pencil clinic OTT, which was completed remotely through video conferencing (Zoom), and the parallel real-world OTT (RW-OTT), which was completed at home between sessions.

Article Synopsis
  • Wearing a cloth face mask during exercise significantly reduces exercise performance metrics like duration and peak oxygen uptake in young adults.
  • The study involved 35 participants undergoing maximal cardiopulmonary exercise tests with and without masks while also performing a cognitive task.
  • Despite the negative impact on physical performance, the use of a cloth face mask did not affect cognitive performance during the tests.

A 23-year-old male competitive athlete performed a maximal cardiopulmonary exercise test on a cycle ergometer with a concurrent cognitive test on an iPad 6 days before and 19 weeks after a nonhospitalized COVID-19 illness. Results indicated reductions in time to exhaustion (-3.25 min), peak oxygen consumption (-1.

Following a traumatic coronary artery dissection and subsequent myocardial infarction from a nonpenetrating strike to the chest by an airborne metal pipe, a 33-year-old male police officer completed 12 weeks of high-intensity, symptom-limited cardiac rehabilitation in order to return to active duty. Physiological and perceptual responses to exercise were used to progress the patient through high-intensity activities that challenged the musculoskeletal and cardiorespiratory systems while simulating real work activities. In addition to substantial improvements in functional capacity (8.

A 29-year-old woman with a left ventricular assist device (LVAD) completed a progressive, symptom-limited cardiac rehabilitation program consisting of boxing, weight-lifting, and aerobic exercise, where she improved her exercise capacity by 2.7 metabolic equivalents ( < 0.001) and demonstrated significant myocardial recovery, allowing for successful LVAD explant 9 months after implantation.

A 56-year-old man with end-stage heart failure performed a 4-week, symptom-limited, progressive inpatient cardiac prehabilitation program while confined to the cardiovascular intensive care unit awaiting heart transplantation. Mobility was limited by an acute gout flare and multiple central venous access lines. He received a tailored prescription of intermittent boxing, supervised hallway ambulation, stair training, and golfing on a putting green on four consecutive weekdays and was encouraged to mobilize with nursing on the remaining days.

A 53-year-old male mountain biker received a total artificial heart and remained in the cardiovascular intensive care unit for 56 days. To reduce functional decline caused by inactivity, he performed a six-session cycle ergometer exercise program in his hospital room. Traditional cardiac responses for exercise prescription were not applicable; therefore, a symptom-limited, monitored progression scheme in conjunction with recommendations for the artificial heart was implemented to modify duration and intensity.

The purpose of this study was to investigate the maximum rate-pressure product of cardiac rehabilitation participants after myocardial infarction, percutaneous coronary intervention, or both during high-intensity resistance training (HI-RT) using continuous blood pressure monitoring. Thirty-four individuals exercised on the leg press machine while being monitored with a continuous blood pressure monitor. The maximum rate-pressure product was significantly lower than the established safety threshold of 36,000 ( < 0.

: Planning, a higher order executive functioning ability important for accomplishing complex everyday tasks, can be differentiated into initial and concurrent (online) planning. In this study, initial plans were codified to assess their impact on task execution. Cognitive correlates of initial planning and task execution were also examined.

There is currently a need to identify feasible and effective interventions to help older individuals suffering from memory loss maintain functional independence and quality of life. To improve upon paper and pencil memory notebook interventions, the Digital Memory Notebook (DMN) application (app) was developed iteratively with persons with cognitive impairment. In this paper we detail a manual-based intervention for training use of the DMN app.

The Cognistat is a widely used neurobehavioral screening instrument that addresses functioning across multiple domains. Unlike many popular neuropsychological tests, the Cognistat does not currently assess learning efficiency for verbal material. The purpose of this study was to develop a screening method for assessing verbal learning efficiency with the Cognistat, investigate the effects of two demographic variables (age and gender) on performance, and to establish cutoff scores for impairment.

The Cognistat is a widely used screening instrument for assessing cognitive functioning. However, the manualized scoring guidelines for one of the questions in the Judgment subtest appear insensitive to responses when examinees answer in light of current societal attitudes. Penalization of examinees is likely to lead to an underestimation of functional ability and a decrease in test validity.
