Transversal Study

UNSTRUCTURED The physical and cognitive loads during exergaming may differ from more conventional cognitive-motor dual-task trainings. The aim of this pilot transversal study was to compare exercise intensity during exergame, cognitive-motor dual-task and single-task training sessions. We recruited healthy young adults who carried out one session of each t type of training: exergaming, cognitive-motor dual-tasking and single-tasking. We used a custom-made exergame as support. The sessions lasted 30 minutes, were spaced at least 24 hours, and took place in random order for each group of 4 participants. We used heart rates to assess exercise intensity, and the modified Borg scale to assess their perception of intensity. Sixteen healthy young participants carried out all sessions. There was no difference between the different types of training in mean heart rates (p = 0.3), peak heart rates (p = 0.5) or Borg scale scores (p = 0.4). Our custom-made exergames measured and perceived physical load did not differ between cognitive-motor dual-task and single-task training. As a result, our exergame can be considered as intense as more traditional physical training. Future studies should be conducted in seniors with or without cognitive impairments and should incorporate an assessment of cognitive performance.

Performance Gains

Transcranial direct current stimulation (tDCS) has been shown to improve single- and dual-task performance in healthy participants and enhance transferable training gains following multiple sessions of combined stimulation and task-practice. However, it has yet to be determined what the optimal stimulation dose is for facilitating such outcomes. We aimed to test the effects of different tDCS intensities, with a commonly used electrode montage, on performance outcomes in a multi-session single/dual-task training and transfer protocol. In a pre-registered study, 123 participants, who were pseudorandomised across four groups, each completed six sessions (pre- and post-training sessions and four combined tDCS and training sessions) and received 20 minutes of prefrontal anodal tDCS at 0.7 mA, 1.0 mA, 2.0 mA, or 15-second sham stimulation. Response time and accuracy were assessed in trained and untrained tasks. The 1.0 mA group showed substantial improvements in single-task reaction time and dual-task accuracy, with additional evidence for improvements in dual-task reaction times, relative to sham performance. This group also showed near transfer to the single-task component of an untrained multitasking paradigm. The 0.7 mA and 2.0 mA intensities varied in which performance measures they improved on the trained task, but in sum, the effects were less robust than for the 1.0 mA group and there was no evidence for the transfer of performance. Our study highlights that training performance gains are augmented by tDCS, but their magnitude and nature are not uniform across stimulation intensity.

Background and Purpose. Traditionally, rehabilitation programs emphasize training balance under single-task conditions to improve balance and reduce risk for falls. The purpose of this case report is to describe 3 balance training approaches in older adults with impaired balance. Case Descriptions. Three patients were randomly assigned to 1 of 3 interventions: (1) single-task balance training, (2) dual-task training under a fixed-priority instructional set, and (3) dual-task training under a variable-priority instructional set. Outcomes. The patients who received balance training under dual-task conditions showed dual-task training benefits; these training benefits were maintained for 3 months. The patient who received variable-priority training showed improvement on novel dual tasks. Discussion. Older adults may be able to improve their balance under dual-task conditions only following specific types of balance training. This case report gives insight on how this intervention might be combined with more traditional physical therapy intervention. [Silsupadol P, Siu KC, Shumway-Cook A, Woollacott MH.

Task Training

A one-dimensional compensatory tracking task and a digit-processing, reaction-time task were combined to assess three aspects of training under time–sharing conditions: (1) Manipulation of desired performance levels for dual-task performance comparing performance under single-task demands vs. adjustment to dual-task demands; (2) training under equal and unequal task priorities in time-sharings; (3) reveated sequence of single-dual task presentations. Six groups of 10 subjects participated in the experiment. Larger performance improvements under time–sharing conditions were observed when performance demands were based on dual–task performances than on single-task performances. Training under unequal task priorities revealed that tracking was more sensitive to priority differences than the digit-processing task. Whereas tracking performances improved during single-task training, digit-processing improved only in the time-sharing conditions, suggesting that improvement on the tracking task is in the specific skill of tracking, while digit-processing improvement results from improved time-sharing ability.

Abstract Objective This study aimed to investigate the effects of dual-task gait training using a treadmill on gait ability, dual-task interference, and fall efficacy in people with stroke. Methods Patients with chronic stroke (N = 34) were recruited and randomly allocated to the experimental or control group. Both groups underwent gait training on a treadmill and a cognitive task. In the experimental group, gait training was conducted in conjunction with the cognitive task, whereas in the control group, the training and the cognitive task were conducted separately. Each intervention was provided for 60 minutes, twice a week, for a period of 6 weeks for both groups. The primary outcomes were as follows: gait parameters (speed, stride, variability, and cadence) under single-task and dual-task conditions, correct response rate (CRR) under single-task and dual-task conditions, and dual-task cost (DTC) in gait parameters and CRR. The secondary outcome was the fall efficacy scale. Results Dual-task gait training using a treadmill improved all gait parameters in the dual-task condition, speed, stride, and variability in the single-task condition, and CRR in both conditions. Difference between the groups was observed in speed, stride, and variability in the dual-task condition. Furthermore, dual-task gait training on a treadmill improved DTC in speed, variability, and cadence along with that in CRR, indicating true improvement of DTC, which led to significant improvement in DTC in speed and variability compared with single-task training. Conclusions Dual-task gait treadmill training was more effective in improving gait ability in dual-task training and DTI than single-task training involving gait and cognitive task separately in people with chronic stroke.

<p style="text-align: justify;"><strong>Background </strong>and Purpose: Balance is controlled through a complex process involving sensory, visual, vestibular and cerebral functioning which get affected by various neurological disorders such as fall. The purpose of the study was to compare the efficiency of three different balance training strategies in an effort to understand the mechanisms underlying training-related changes in dual task balance performance of older adults with balance impairment.</p> <p style="text-align: justify;"><strong>Methods:</strong> 45 older adults with balance impairment were recruited and randomly assigned to three groups. Group one received single task balance training, group two received dual task training balance training under fixed priority, group three received dual task balance training under variable priority. Subjects received one-hour individualized training sessions, five times in a week for two weeks. Berg balance scale and time up and go test were the outcome measure and their scores for all groups were taken prior and after the training.</p> <p style="text-align: justify;"><strong>Results:</strong> One-way analysis of variance was used to analyse the difference among the balance improvement in Group one, two and three. And the results revealed that post intervention scores were highly significant (p£ 0.05) in group two and group three performed better than group one.</p> <p style="text-align: justify;"><strong>Conclusion:</strong> In conclusion, dual task training is effective in improving balance under dual task context in older adults with balance impairment, and single task training may not generalize to balance performance under dual task conditions.</p>

Background: Parkinson disease (PD) is characterized by motor and non-motor symptoms that affect patients’ functions, especially while performing dual-tasks a critical factor in everyday living. However, many controversies exist about the benefits of dual-task training in patients with PD. Objectives: This study assessed the efficacy of motor and cognitive dual-task training in improving balance and gait parameters in people with idiopathic PD. Materials & Methods: A single-blind controlled trial was conducted on PD patients living in Guilan Province of Iran, in 2018-2019. A total of 30 PD patients (Hoehn and Yahr stage II-III while on medication) were assigned to the cognitive dual-task training group (n=10), motor dual-task training group (n=10), and single-task control group (n=10). All groups received 30 sessions of different exercises for 10 consecutive weeks. The patients’ balance and some spatiotemporal gait parameters were respectively assessed with timed up and go test and HD VideoCam-Kinovea before and after training and then 1 month later. Results: Both dual-task and single-task trainings improved the outcome measures (timed up and go test (F=535.54; P=0.000), stride length (F=87.41; P=0.00), stride time (F=102.11; P=0.00), cadence (F=286.36; P=0.00), swing time (F=48.90; P=0.00), and stance time (F=40.56; P=0.00)). These improvements were maintained at 1-month follow-up, although the effect slightly reduced. No significant differences were found between the study groups (P>0.05). Conclusion: Motor/cognitive dual-task training and single-task training were found to be significantly and equally effective in improving balance and gait parameters in people with PD.

In two experiments we examined the effects of single- and dual-task training on the acquisition and transfer of dual-task skill. Subjects performed two consistently mapped (CM) visual search tasks (word-category search and spatial-pattern search). Experiment 1 demonstrated benefits in both reaction time and accuracy for dual-task practice over comparable single-task practice when the two search tasks were combined. Experiment 2 examined the effects of task timing under single-task, synchronous dual-task, and asynchronous dual-task conditions. Benefits similar to those found in the first experiment were obtained. These results suggest that dual-task training can be more effective than single-task training when two dissimilar CM search tasks need to be performed together.

Objective: To investigate the effects of dual-task balance training on postural performance in patients with multiple sclerosis as compared with single-task balance training. Design: Double-blind, pretest-posttest, randomized controlled pilot trial. Setting: Local Multiple Sclerosis Society. Subjects: A total of 47 patients were randomly assigned to two equal groups labeled as single-task training and dual-task training groups. Interventions: All patients received supervised balance training sessions, 3 times per week for 4 weeks. The patients in the single-task group performed balance activities, alone. However, patients in dual-task group practiced balance activities while simultaneously performing cognitive tasks. Main measures: The 10-Meter Walk Test and Timed Up-and-Go under single-task and dual-task conditions, in addition to Activities-specific Balance Confidence, Berg Balance Scale, and Functional Gait Assessment were assessed pre-, and post intervention and also 6-weeks after the end of intervention. Results: Only 38 patients completed the treatment plan. There was no difference in the amount of improvement seen between the two study groups. In both groups there was a significant effect of time for dual-10 Meter Walk Test (F1, 36=11.33, p=0.002) and dual-Timed Up-and-Go (F1, 36=14.27, p=0.001) but not for their single-tasks. Moreover, there was a significant effect of time for Activities-specific Balance Confidence, Berg Balance Scale, and Functional Gait Assessment ( P<0.01). Conclusions: This pilot study did not show more benefits from undertaking dual-task training than single-task training. A power analysis showed 71 patients per group would be needed to determine whether there was a clinically relevant difference for dual-task gait speed between the groups.
