Balance Performance of Post-Call Medical Residents

Background: Fatigue is thought of as a leading cause of iatrogenic accidents. A significant deterioration in qualitative balance function has been shown in sleep deprived individuals. Aim/Objectives: To quantify the degree to which balance is impaired by sleep deprivation (SD) in post-call medical residents. Methods: Medical residents voluntarily underwent computed dynamic posturography (CDP) before and after an on-call night, at an identical time of the day. Order of test performance was random to avoid behavioral learning. Each participant served as his or her own control. Results: Seventeen residents were enrolled (median age 32years). Average sleeping duration the night before and during the night shift was 6.5 and 1 hour, respectively. The average response times difference between alert and fatigued was 10.15 milliseconds (95% CI: 6.81-13.49 milliseconds), yielding a significantly prolonged response times from 120 milliseconds before to 130 milliseconds after the night shift ( P < .001). Comparison of additional measurements of CDP performance did not differ between test conditions. Conclusion: Medical residents are fatigued due to the effect of on-call nights. Sleep deprivation prolongs response times to vestibular stimuli. This finding probably has an effect on execution of manual skills and may reflect a more generalized slowing of responses and overall performance impairment. Significance: The vestibular system is susceptible to SD.

The Relationship ◽

And Task

Postural sway has been demonstrated to increase following exposure to different types of motion. However, limited prior studies have investigated the relationship between exposure to normative on-road driving conditions and standing balance following the exposure. The purpose of this on-road study was to quantify the effect of vehicle motion and task performance on passengers’ post-drive standing balance performance. In this study, trunk-based kinematic data were captured while participants performed a series of balance exercises before and after an on-road driving session in real-time traffic. Postural sway for all balance exercises increased following the driving session. Performing a series of ecologically relevant visual-based tasks led to increases in most post-drive balance metrics such as sway position and velocity. However, the post-drive changes following the driving session with a task were not significantly different compared to changes observed following the driving session without a task. The post-drive standing balance performance changes observed in this study may increase vulnerable users’ risk of falling. Wearable sensors offer an opportunity to monitor postural sway following in-vehicle exposures.

✓ Nineteen psychiatric patients undergoing bilateral cryogenic cingulate cortex lesions were extensively evaluated pre- and postoperatively with objective measures of intelligence, higher cortical functions, memory, and emotional status. Following surgery the patients as a group revealed no significant deterioration of functions; rather, they demonstrated improvement that could be interpreted as the result of decline in anxiety. Investigations of individual patients revealed that the overall test performance was improved in 13 and substantially unchanged in three, whereas three demonstrated some decline in performance. These results were discussed in terms of the characteristics of the changes across the various tests.

HighlightsThe farming population is at risk of injury due to sleep deprivation.Loss of sleep during previous night affects balance performance in farmers.Objective measures of sleep are more reliable than subjective measures for predicting balance performance.Abstract. This study aimed to investigate the ability of both subjective and objective sleep measures to predict balance difficulty in agricultural workers. Seven male farmers from rural Nebraska were analyzed for static balance performance following a bout of sleep. Actiwatches were used to measure objective sleep hours and subjective questionnaires, including the Epworth Sleepiness Scale and the Pittsburgh Sleep Quality Index, were used to measure subjective hours of sleep and sleep quality. The participants were observed for 12 sessions, with six in planting season and six in harvest season. Static balance testing consisted of measuring the area, total displacement, and maximum range in the anteroposterior and mediolateral directions of the individual’s center of pressure with Tekscan pressure mats. Overall, it was found that objective measures had a higher correlation with the magnitude of balance deviations than subjective measures.

The purpose of this investigation was to examine a single-anagram, a double-anagram, and multi-anagram versions of the Anagram Persistence Task (APT) for factorial validity, reliability, and convergent validity. Additionally, a battery of intelligence tests was administered to examine convergent validity. Based on an unrestricted factor analysis, two factors were uncovered from the 14 anagram (seven very difficult and seven very easy) response times: test-taking persistence and verbal processing speed. The internal consistency reliabilities for the single-anagram, double-anagram, and multi-anagram (seven difficult anagrams) measures were .42, .85, and .86, respectively. Furthermore, all three versions of the APT correlated positively with intelligence test performance ( r ≈ .22). However, the double-anagram and multi-anagram versions also evidenced negative, nonlinear effects with intelligence test performance ( r ≈ −.15), which suggested the possibility of testee adaptation. Taking psychometrics and administration time into consideration, simultaneously, the double-anagram version of the APT may be regarded as preferred.

Grooved Pegboard Test

Abstract Background Motor impairment in patients with normal pressure hydrocephalus (NPH) can extend beyond gait and include deficits in upper extremity functions and psychomotor speed. Evaluation of upper extremity function will be helpful for NPH patients who are unable to ambulate (e.g., wheelchair-bound patients) and may not be able to comply with the gait evaluation. Our study aimed to explore the use of the grooved pegboard test to assess responsiveness to the cerebrospinal fluid (CSF) tap test in patients with NPH. Methods Seventy-seven possible NPH patients were enrolled from 2013 to 2018. All patients underwent detailed neuropsychological and walking assessments, CSF tap tests, and brain magnetic resonance imaging. The grooved pegboard test results before and after the CSF tap test were compared and correlated with the other clinical assessments. In diffusion tensor imaging analysis, the fractional anisotropy (FA) and mean diffusivity (MD) values of periventricular white matter were measured by the region of interest method and were correlated with pegboard test performance.Results The grooved pegboard test scores significantly improved after the CSF tap test and correlated with patient walking ability, cognitive function, and functional scores (P < 0.01). The improvement ratios in the complex visual motor speed index (i.e., the grooved pegboard test performance combined with the Symbol-Digit Modalities Test performance) were significantly different between the CSF tap test responder and nonresponder groups. The grooved pegboard test times were significantly correlated with the FA values in right periventricular lesions (P=0.017).Conclusions The performance on the grooved pegboard test was related to lower extremity motor ability and cognitive function. It can be used as an alternative evaluation tool for patients who are unable to ambulate and may not be able to comply with the gait evaluation.

Increase In Risk

It is well known that sleep deprivation induces fatigue and that fatigue induces impaired cognition. Studies have demonstrated that long work hours, restricted sleep, time pressure and high demands may cause impaired performance in physicians. Some studies have shown through laparoscopic simulation that surgeons, when deprived of sleep, take longer to perform the procedure, make more unnecessary movements with their instruments and significantly more mistakes. Surgeons with an opportunity for sleep of less than 6 hours on the previous on-call night shift had an 83% increase in risk of postoperative complications when working the following day.
