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.

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.

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.

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.

The Impact

The motivation of investigation was to discover the impact of motor dual task training (MDTT) vs single task training (STT) on useful parity in post stroke patients. Thirty first beginning of one-sided ischemic “Middle Cerebral Artery (MCA)” domain stroke patients are haphazardly designated into 2 gatherings the STT gathering (n=15) got single task strengthening and balance practices and MDTT (n=11) got strengthening &balance practice alongside an optional engine task. Intercession is provided 45 minutes for every session, once in a day, 5 days of week for about fourteen days. The parity was dissected utilizing Berg Balance Scale (BBS).In 2 groups, balance expressively enhanced in BBS. Compared with STT group; MDTT group reached much statistically important development. The MDTT exercises efficiently promote balance initial in stroke patients. How parity is influenced relies upon a few variables, comprising the degree of sensory system harm, the number and degree of tactile misfortunes, and the accessibility of different faculties for pay. In numerous occurrences, greater than one tactile framework is hindered.

The aim was to compare the effectiveness of dual-task training (DTT) compared to single mobility training (SMT) on dual-task walking, mobility and cognition, in persons with Multiple Sclerosis (pwMS). Forty pwMS were randomly assigned to the DTT or SMT groups. The DTT-group performed dual-task exercises using an interactive tablet-based application, while the SMT-group received conventional walking and balance exercises. Both interventions were supervised and identical in weeks (8) and sessions (20). Nine cognitive-motor dual-task conditions were assessed at baseline, after intervention and at 4-weeks follow-up (FU). The dual-task cost (DTC), percentage change of dual-task performance compared to single-task performance, was the primary outcome. Mobility and cognition were secondarily assessed. Mixed model analyses were done with group, time and the interaction between group and time as fixed factors and participants as random factors. Significant time by group interactions were found for the digit-span walk and subtraction walk dual-task conditions, with a reduction in DTC (gait speed) for the DTT maintained at FU. Further, absolute dual-task gait speed during walking over obstacles only improved after the DTT. Significant improvements were found for both groups in various motor and cognitive measures. However, the DTT led to better dual-task walking compared to the SMT.
