Abstract Objective While there is evidence on the short-term effects of unilateral balance training (BT) on bipedal balance performance, less is known on the acute effects of unilateral BT on unilateral (i.e., ipsi- and contralateral) balance performance. Thus, the present study examined the acute effects of a single unilateral BT session conducted with the non-dominant, left leg or the dominant, right leg on ipsilateral (i.e. retention) and contralateral (i.e., inter-limb transfer) balance performance in healthy young adults (N = 28). Results Irrespective of practice condition, significant improvements (p < 0.001, d = 1.27) in balance performance following a single session of unilateral BT were observed for both legs. Further, significant performance differences at the pretest (p = 0.002, d = 0.44) to the detriment of the non-dominant, left leg diminished immediately and 30 min after the single unilateral BT session but occurred again 24 h following training (p = 0.030, d = 0.36). These findings indicate that a single session of unilateral BT is effective to reduced side-to-side differences in balance performance, but this impact is only temporary.

Rationale Restoration of adequate standing balance after stroke is of major importance for functional recovery. POstural feedback ThErapy combined with Non-invasive TranscranIAL direct current stimulation (tDCS) in patients with stroke (POTENTIAL) aims to establish if cerebellar tDCS has added value in improving standing balance performance early post-stroke. Methods Forty-six patients with a first-ever ischemic stroke will be enrolled in this double-blind controlled trial within five weeks post-stroke. All patients will receive 15 sessions of virtual reality-based postural feedback training (VR-PFT) in addition to usual care. VR-PFT will be given five days per week for 1 h, starting within five weeks post-stroke. During VR-PFT, 23 patients will receive 25 min of cerebellar anodal tDCS (cb_tDCS), and 23 patients will receive sham stimulation. Study outcome Clinical, posturographic, and neurophysiological measurements will be performed at baseline, directly post-intervention, two weeks post-intervention and at 15 weeks post-stroke. The primary outcome measure will be the Berg Balance Scale (BBS) for which a clinical meaningful difference of six points needs to be established between the intervention and control group at 15 weeks post-stroke. Discussion POTENTIAL will be the first proof-of-concept randomized controlled trial to assess the effects of VR-PFT combined with cerebellar tDCS in terms of standing balance performance in patients early post-stroke. Due to the combined clinical, posturographical and neurophysiological measurements, this trial may give more insights in underlying post-stroke recovery processes and whether these can be influenced by tDCS.

Introduction: The current pilot study aimed to examine the short-term effects of ankle Elastic Therapeutic Taping (ETT) on static and dynamic balance. Methods: Twenty-Four individuals with chronic stroke were assigned to an experimental or control group (n=12/group); they both received Conventional Physical Therapy (CT) for 3 weeks, 3 times per week. The experimental group additionally underwent taping to the ankle of the paretic side continuously for 3 weeks. Standardized measures for static and dynamic balance were administered at pre-test and post-test and analyzed using Wilcoxon and Analysis of Covariance (ANCOVA). Results: The experimental group significantly improved on two measures, Biodex anterior-posterior static (P=0.03) and medial-lateral dynamic (P=0.04) balance indices, compared to the controls. Both groups improved within their respective groups for Berg Balance Scale and Functional Reach (P<0.05). Static balance consistently improved across measures with the experimental intervention with large effect sizes. Conclusion: Ankle ETT, combined with CT, may be effective in the short-term for improving static and dynamic balance in stroke, compared to CT alone. A future larger randomized trial with longer follow-up is required to establish this method’s effectiveness.
