“…19 The mechanisms underlying such benefit are likely to be multifactorial. For instance, auditory feedback could have provided external guidance for repositioning, 12 enhanced error feedback, 6 enhanced multisensory integration, 39 strengthened perceptuomotor representations, 40 allowed selective attentional allocation, 41,42 and more 43,44 (for a detailed discussion, see Ref. 19).…”

Our study analyzed the effects of real-time auditory feedback on intermodal learning during a bilateral knee repositioning task. Thirty healthy participants were randomly allocated to control and experimental groups. Participants performed an active knee joint repositioning task for the four target angles (20°, 40°, 60°, and 80°) bilaterally, with or without additional real-time auditory feedback. Here, the frequency of auditory feedback was mapped to the knee's angle range (0-90°). Retention measurements were performed on the same four angles, without auditory feedback, after 15 min and 24 hours. A generalized knee proprioception test was performed after the 24-h retention measurement on three untrained knee angles (15°, 35°, and 55°). Statistical analysis revealed a significant enhancement of knee proprioception, shown as a lower knee repositioning error with auditory feedback. This enhancement of proprioception also persisted in tests performed between the 5th and 6th auditory-motor training blocks (without auditory feedback). Enhancement in proprioception also remained stable during retention measurements (after 15 min and 24 h). Similarly, enhancement in the generalized proprioception on untrained knee angles was evident in the experimental group. This study extends our previous findings and demonstrates the beneficial effects of real-time auditory feedback to facilitate intermodal learning by enhancing knee proprioception in a persisting and generalized manner.

Background Cognitive and postural tasks require common cognitive mechanisms, resulting in conflicts when both tasks are simultaneously performed. The presence of neuromotor dysfunctions, such as Down syndrome, may impair coordination processes required to perform dual-tasks. The objective of this study was to investigate the dual-task effects on postural sway during sit-to-stand movements in typical children and children with Down syndrome in a cross-sectional study. Methods Twenty six typical children (10.2 ± 2.4 years) and 21 with Down syndrome (10.3 ± 2.3 years) performed sit-to-stand in the following conditions: (1) simple task; (2) dual-task bimanual activity (DT-Bim): sit-to-stand while carrying a tray using both hands; (3) dual-task unimanual dominant activity (DT-Uni-Dom): sit-to-stand while holding a plastic cup simulating water using the dominant hand; (4) dual-task unimanual nondominant activity (DT-Uni-Nondom): sit-to-stand movement while holding a plastic cup simulating water. For data analysis, sit-to-stand was divided into three phases: preparation (phase 1), rising (phase 2), and stabilisation (phase 3). The following variables were calculated for each phase: anterior-posterior and medial-lateral amplitude of centre-of-pressure displacement, anterior-posterior and medial-lateral velocity of centre-of-pressure sway and area of centreof-pressure sway. Results Children with Down syndrome showed greater sway than typical children in all sit-to-stand phases. Typical children showed greater anterior-posterior amplitude in phase 2 of sit-to-stand during DT-Uni Nondom compared with DT-Uni Dom. Children with Down syndrome during simple task condition showed greater and faster values sway in phases 2 and 3 of sit-to-stand movement than in DT-Bim activity, DT-Uni Dom activity and DT-Uni Nondom activity. During the condition of DT-Bim activity, these children showed lower anterior-posterior velocity of sway in phase 2 than during DT-Uni Dom activity. Conclusions Children with Down syndrome showed greater postural sway during sit-to-stand than typical children. The addition of a concurrent motor task to sit-to-stand impacted postural sway in different intensities and in different ways across groups. Dualtasks increased body sway in typical children in the DT-Uni Nondom condition compared with dominant one. In children with Down syndrome, dual-tasks decreased body sway, apparently resulting in a postural strategy of stiffness.

“…However, those activities often require simultaneous cognitive and physical demands . In other words, daily life activities need the ability to carry out a primary motor task while attention is focused on an external source of attention (motor, cognitive, or emotional) . This paradigm where two tasks are executed at the same time is called dual task.…”

Regarding physical capacities evaluated under this paradigm, apart from strength and mobility, flexibility results might be limited by pain during the evaluation in fibromyalgia patients.…”

Objective To evaluate the effects of 24‐week exergame intervention in the physical fitness of women with fibromyalgia in both single‐ and dual‐task conditions. Design Single‐blinded, randomized controlled trial. Setting University facilities. Participants Fifty‐five women with fibromyalgia, recruited from the local fibromyalgia association, were randomly assigned to one of the two groups: exercise group and control group. Intervention The exercise group completed 24 weeks of supervised and group‐based exergame protocol, divided into two sessions of 60 minutes. The intervention was focused on mobility, postural control, upper and lower limbs coordination, aerobic fitness, and strength. Main outcome measures The strength of the upper limbs was measured using the arm curl test. The mobility skill was assessed through the timed‐up and go test, and the flexibility of both upper and lower limbs was measured using the back scratch and the sit and reach tests, respectively. Results Fifty participants completed the study. In the single‐task condition, exergame intervention led to significantly higher effects in the arm curl test (P = 0.008), sit and reach test (P = 0.033), and timed‐up and go test (P = 0.021). Moreover, under dual‐task condition, exergames led to significant effects in all the physical fitness tests (arm curl test, timed‐up and go test, back scratch test, and sit and reach test) compared to the control group. Conclusions Exergame is an effective tool to improve the physical fitness in women with fibromyalgia under single or dual‐task conditions.
