Introduction: Dual tasking is common in activities of daily living (ADLs) and the ability to perform them usually declines with age. While cognitive aspects influence dual task (DT) performance, most DT-cost (DT-C) related metrics include only time- or speed- delta without weighting the accuracy of cognitive replies involved in the task.Objectives: The primary study goal was to weight the accuracy of cognitive replies as a contributing factor when estimating DT-C using a new index of DT-C that considers the accuracy of cognitive replies (P-index) in the instrumented timed up and go test (iTUG). Secondarily, to correlate the novel P-index with domains of the Mini-Mental State Examination (MMSE).Methods: Sixty-three participants (≥85 years old) took part in this study. The single task (ST) and DT iTUG tests were performed in a semi-random order. Both the time taken to complete the task measured utilizing an inertial measurement unit (IMU), and the accuracy of the cognitive replies were used to create the novel P-index. Clinical and sociodemographic data were collected.Results: The accuracy of the cognitive replies changed across the iTUG phases, particularly between the walk 1 and walk 2 phases. Moreover, weighting 0.6 for delta-time (W1) and 0.4 for cognitive replies (W2) into the P-index enhanced the prediction of the MMSE score. The novel P-index was able to explain 37% of the scores obtained by the fallers in the “spatial orientation” and “attention” domains of the MMSE. The ability of the P-index to predict MMSE scores was not significantly influenced by age, schooling, and number of medicines in use. The Bland-Altman analysis indicated a substantial difference between the time-delta-based DT-C and P-index methods, which was within the limits of agreement.Conclusions: The P-index incorporates the accuracy of cognitive replies when calculating the DT-C and better reflects the variance of the MMSE in comparison with the traditional time- or speed-delta approaches, thus providing an improved method to estimate the DT-C.

ABSTRACTBackground:The purpose of the study was to investigate the relationship between dual task walking, cognition, and depression in oldest old people living in the community.Methods:We conducted an observational cross-sectional study at Federal University of São Carlos (Brazil). We assessed 67 community-dwelling older adults aged 80 years and over, who were able to walk alone and did not present with a risk of dementia (assessed by Mini-Mental State Examination, MMSE). The assessment consisted of anamnesis, dual task using the Timed Up and Go test associated with a motor task (TUGT-motor) and a cognitive task (TUGT-cognitive); cognitive measures using MMSE, Montreal Cognitive Assessment (MoCA), Clock Drawing test (CDT) and verbal fluency, and depressive measures by the Geriatric Depression Scale (GDS).Results:There was a correlation with higher magnitude between cognitive tests and TUGT-cognitive, compared to TUGT-motor. For TUGT-motor, the highest correlations with cognitive tests were found between time and MMSE, MoCA (total score), and MoCA visuospatial/executive domain. For TUGT-cognitive, the highest correlations with cognitive tests were between number of steps and MMSE and between time and MMSE. GDS showed a significant weak correlation with number of steps taken in TUGT-motor, wrong words, and correct/time of TUGT-cognitive.Conclusions:Dual task performances are associated with cognition in oldest old. Furthermore, dual task tests have less influence of educational level, are functional, fast, and easily applicable in clinical practice. Future studies are needed to confirm if dual task test is useful for cognitive screening in oldest old.

Резюме. Правильний і обґрунтований вибір інструментальних методів оцінювання функціо-нального стану пацієнта є обов’язковою умовою адекватної фізичної терапії. Особливе місце цей аспект займає в системі нейрореабілітації пацієнтів з хворобою Паркінсона в Україні, оскільки на сьогодні кількість осіб, що потребують систематичної фізичної терапії, сягає 23 900 тис. Наростаюча маніфестація моторних і немоторних симптомів при хворобі Паркін-сона, від яких часто вирішальною мірою залежить тяжкість стану пацієнта, негативно впливає на якість його життя. Наявні функціональні порушення, які є самостійними проявами хвороби Паркінсона, вимагають специфічного підходу до комплексного інструментального досліджен-ня цих порушень для визначення диференційно-діагностичних критеріїв та оцінювання впливу фізіотерапевтичного втручання. Мета. Проаналізувати наявні інструменти оцінювання впливу фізичної терапії на осіб з хворобою Паркінсона. Методи. Теоретичний аналіз та узагальнення зарубіжних даних спеціальної науково-методичної літератури з питань застосування інстру-ментів оцінювання при хворобі Паркінсона та їх інформативності і надійності у фізичній терапії. Результати. Представлені дані свідчать, що ефективність запроваджених заходів фізичної терапії при хворобі Паркінсона залежить від правильно підібраних інструментів оцінювання, які дозволяють оцінити моторні і немоторні проблеми через призму життєдіяльності і якості життя пацієнта. Основним інструментом оцінювання для вирішення цього питання вважаєть-ся Уніфікована рейтингова шкала хвороби Паркінсона MDS-UPDRS, яка дозволяє об’єктивно оцінити моторні і немоторні аспекти життя пацієнта і його рухову активність. Оскільки наявні моторні й аксіальні рухові порушення негативно впливають на повсякденну функціональну активність пацієнта, для верифікації цих порушень пропонують використовувати тест для оці-нювання часу підйому і ходьби (Timed Up and Go (TUG)); тест з подвійним завданням (Dual-Task TUG (TUG-DT)) та шкалу рівноваги Берга (Berg Balance Scale (BBS)). Але виходячи з того, що ці тести недостатньо чутливі до невеликих змін у рухливості при хворобі Паркінсона, особливо на середніх і пізніх стадіях захворювання, їх доцільно поєднувати з одним із кількісних тестів для оцінювання ходьби: 10-метровим тестом ходьби (10 Meter Walk Test (10MW)) та 6-хвилинним тестом ходьби (Six Minute Walk Distance (6MWT)). Поняття «життєдіяльність» включає в себе не тільки переміщення, її оцінювання має бути доповнено аналізом ступеня впливу наявних по-рушень на повсякденну діяльність, тобто на якість життя пацієнта. Найбільш інформативними інструментами для проведення цього аналізу є універсальні і специфічні при хворобі Паркінсо-на опитувальники з метою оцінювання стану здоров’я SF-36, EuroQOL (EQ-5D) і PDQ-39 (The Parkinson’s Disease Questionnaire). Результати аналізу та узагальнення даних науково-мето-дичної літератури дають підставу встановити, що маніфестація порушень та їх варіабельність при хворобі Паркінсона стають серйозною проблемою у досягненні кінцевого результату за-проваджених заходів фізичної терапії на всіх стадіях захворювання. Використання в комплексі стандартної експертно-реабілітаційної діагностики спеціальних інструментів оцінювання дозволяє об’єктивізувати оцінювання клінічної інформації та стимулює розроблення особисто-орієнтованих реабілітаційних стратегій із застосуванням заходів фізичної терапії, спрямованих на покращення якості життя пацієнтів з хворобою Паркінсона. Ключові слова: хвороба Паркінсона, фізична терапія, якість життя, інструменти оцінювання, достовірність, надійність, валідність.

Abstract Background: The aim of this study was to evaluate the effects of cognitive and physical loads on dynamic and static balance of older adults under single, dual and multi-task conditions. Methods: The effects of single versus combined (dual-task and multi-task) cognitive (to speak out the name of the weekdays in a reverse order) and physical (with three levels including handling weights of 1kg, 2kg and 3kg in each hand) loads on dynamic and static balance of 42 older adults (21 males and 21 females), aged ≥ 60 years were studied. Dynamic and static balance measures were evaluated using the Timed Up and Go (TUG) and stabilometer (sway index) tests, respectively. Results: The TUG speed of female participants was generally slower than that of male participants. Cognitive task influenced the participants’ dynamic balance during the dual-task conditions, while the static balance was not affected in this phase. The dynamic and static balance measures were more influenced when performing the multi-tasks than when doing the dual-tasks. The effects of various levels of physical demand on the dynamic balance varied greatly under dual- and multi-task conditions. Conclusions: The findings add to the understanding of the factors influencing the elderly balance and control under cognitive and physical functioning.

Abstract Aim To elucidate the association between the occurrence of falls and timed “up and go” (TUG) test score in a dual-task condition among community-dwelling older adults by age group. Methods This longitudinal observation study included 987 community-dwelling older adults at baseline. A TUG test (single-TUG) and a TUG test while counting aloud backward from 100 (dual-TUG) were conducted at baseline. The dual-task cost (DTC) value was computed from these results. Data on fall history were obtained using a self-administered questionnaire at the 1-year follow-up. At follow-up, 322 participants had dropped out and six participants had missing data for falls. The final analysis included 658 individuals (follow-up rate: 658/987, 67%) divided into a young-older adult group (aged 60–74 years) and an old-older adult group (aged 75 years or older). Associations between the occurrence of falls and TUG-related values were analyzed by age group using multivariate logistic regression models. Results For old-older adults, there were significant associations between the occurrence of falls and DTC value (odds ratio [OR] 0.981, 95% confidence interval [CI]: 0.963–0.999, p = 0.040) and single-TUG score (OR 1.129, 95% CI: 1.006–1.268, p = 0.039). However, no significant associations were observed for young-older adults. Conclusions Slower single-TUG test score and lower DTC value are associated with the occurrence of falls among old-older adults but not among young-older adults. Dual task assessment is useful for predicting falls in TUG fall assessment for old-older adults.

In the sport of basketball, it is important to practice shooting the ball to develop the skill of making the shot in the basket at a high efficiency. Making shots at a high efficiency allows the player to succeed at a high level in the sport. The main focus of the paper describes the design and development of an automatic basketball rebound (ABR) system. The developed ABR provides a system that will launch the ball back to the player at any position on the court within a 50-foot radius. This is accomplished by a variable spring loaded launching mechanism that will compress a spring, depending on the players location, to generate the appropriate force required to launch the ball back to the player. The novel launching mechanism developed is mounted to a rotary table that ensures the launching mechanism is in the correct orientation with the player once the ball is launched. The player is outfitted with an inertial measurement unit to track their position using a method known as dead reckoning. This information is relayed back to a microcontroller that determines the system response. The ABR system is made from lightweight materials and is compact such that it is easy to move around compared to its predecessors.

Objective The aim of this study is to examine the effects of cognitive and physical loads on dynamic and static balance performance of healthy older adults under single-, dual-, and multi-task conditions. Background Previous studies on postural control in older adults have generally used dual-task methodology, whereas less attention has been paid to multi-task performance, despite its importance in many daily and occupational activities. Method The effects of single versus combined (dual-task and multi-task) cognitive (to speak out the name of the weekdays in a reverse order) and physical (with three levels including handling weights of 1, 2, and 3 kg in each hand) loads on dynamic and static balance performance of 42 older adults (21 males and 21 females) aged ≥60 years were examined. Dynamic and static balance measures were evaluated using the Timed Up and Go (TUG) and stabilometer (sway index) tests, respectively. Results The TUG speed of female participants was generally slower than that of male participants. Age had no effect on balance performance measures. Under dual-task conditions, cognitive load decreased the dynamic balance performance, while the physical task levels had no effect. The dual-task conditions had no impact on the static balance performance. The effects of cognitive and physical loads on dynamic balance performance varied under dual- and multi-task conditions. Conclusion The findings highlight differences between dual- and multi-task protocols and add to the understanding of balance performance in older adults under cognitive and physical loads. Application The present study highlights differences between dual- and multi-task methodologies that need to be considered in future studies of balance and control in older adults.

Abstract: The activities of standing, walking and sitting performed in association with other tasks (e.g., holding an object) are very common in our everyday lives. The performance of these concurrent tasks may require greater attentional demand. Therefore, the aim of the current study was to evaluate the performance of young healthy adults on the "Timed Up and Go" (TUG) test on the dual task paradigm. Twelve young adults performed the TUG test in four conditions: a) no secondary task; b) with a task of holding a tube with both hands without defined attentional focus; c) holding the tube with internal attentional focus (i.e., minimize the hands motion); and, d) holding the tube with external attentional focus (i.e., minimize the movement of a light from a laser pointer fixed to the tube which reflected on a target placed on the wall). A digital chronometer was used to record the time taken to complete the tests. The time spent in the conditions with secundary task relative to the original TUG test was also analyzed. The movement variability of the tube was assessed by recording the kinematics of markers placed on the lateral side of the tube. Analyses of variance were used to compare the total and relative time and tube variability across conditions. More time was necessary to complete the TUG test when specific instruction about the secondary task was given, mainly when related to the movement of the tube (external focus). However, the variability of the tube was also smallest in that condition. Therefore, the addition of a secondary task (holding a tube) affects the performance of TUG only when specific instructions on the attentional focus are given in particular about external effects of the secondary task.Key Words: Time up and Go test, dual task, attentional focus, secondary tasks.

The aim of this study was to determine whether stroke survivor’s gait performance during dual-task Timed Up and Go (TUG) test is correlated with the level of functional balance and motor impairment. Thirty stroke survivors (22 men, 8 women) were recruited for this study. The level of functional balance (Berg Balance Scale) and motor impairment (Fugl-Meyer assessment lower extremity) were assessed prior to the TUG test. TUG test was conducted under three attentional loading conditions (single, dual motor, and dual-cognitive). The time and number of steps were used to quantify gait parameters. The Spearmen’s rank correlation coefficient was used to evaluate the relationship between these variables. There was moderate to strong negative correlation between functional balance and gait parameters (range −0.53 to −0.73,P<0.05). There was a weak negative correlation observed between the time taken to complete the single task and motor impairment (rs=-0.43;P=0.02) dual motor task and motor impairment (rs=-0.41;P=0.02). However, there were no significant correlations between lower limb motor impairment and the number of steps in all conditions. These findings suggest that functional balance may be an influential domain of successful dual-task TUG in stroke.
