Titre : Effect of single-session dual-tDCS before physical therapy on lower-limb performance in sub-acute stroke patients: A randomized sham-controlled crossover study Type de document : texte imprimé Auteurs : Wanalee Klomjai ; Benchaporn Aneksan ; Anuchai Pheungphrarattanatrai ; Thanwarat Chantanachai ; Nattha Choowong ; Soontaree Bunleukhet ; Paradee Auvichayapat ; Yongchai Nilanon ; Vimonwan Heingkaew Année de publication : 2018 Article en page(s) : p. 286-291 Note générale : Doi : 10.1016/j.rehab.2018.04.005 Langues : Anglais (eng) Mots-clés : tDCS Lower limb Stroke Physical therapy Rehabilitation Résumé : Anodal stimulation increases cortical excitably, whereas cathodal stimulation decreases cortical excitability. Dual transcranial direct current stimulation (tDCS; anodal over the lesioned hemisphere, cathodal over the non-lesioned hemisphere) was found to enhance motor learning. The corresponding tDCS-induced changes were reported to reduce the inhibition exerted by the unaffected hemisphere on the affected hemisphere and restore the normal balance of the interhemispheric inhibition. Most studies were devoted to the possible modification of upper-limb motor function after tDCS; however, almost no study has demonstrated its effects on lower-limb function and gait, which are also commonly disordered in stroke patients with motor deficits. In this randomized sham-controlled crossover study, we included 19 patients with sub-acute stroke. Participants were randomly allocated to receive real or sham dual-tDCS followed by conventional physical therapy with an intervention interval of at least 1 week. Dual-tDCS was applied over the lower-limb M1 at 2-mA intensity for 20min. Lower-limb performance was assessed by the Timed Up and Go (TUG) and Five-Times-Sit-To-Stand (FTSTS) tests and muscle strength was assessed by peak knee torque of extension. We found a significant increase in time to perform the FTSST for the real group, with improvements significantly greater than for the sham group; the TUG score was significantly increased but not higher than for the sham group. An after-effect on FTSTS was found at approximately 1 week after the real intervention. Muscle strength was unchanged in both limbs for both real and sham groups. Our results suggest that a single session of dual-tDCS before conventional physical therapy could improve sit-to-stand performance, which appeared to be improved over conventional physical therapy alone. However, strength performance was not increased after the combination treatment. Permalink : ./index.php?lvl=notice_display&id=80617

[article]
Titre : Rehabilitation improves walking kinematics in children with a knee varus: Randomized controlled trial Type de document : texte imprimé Auteurs : Amir Ali Jafarnezhadgero ; Mahdi Majlesi ; Hojat Etemadi ; D.G.E. Robertson Année de publication : 2018 Article en page(s) : p. 125-134 Note générale : Doi : 10.1016/j.rehab.2018.01.007 Langues : Anglais (eng) Mots-clés : Genu varus Gait Lower limb Joint angle Résumé : Background
Previous studies have demonstrated increased medial stresses in knee varus alignment. Selecting a suitable treatment strategy for individuals with knee malalignment should be a priority.
Objectives
We aimed to investigate the effects of a 16-week corrective exercise continuum (CEC) program on 3-D joint angles of the dominant and non-dominant lower limbs in children with genu varus during walking.
Methods
Overall, 28 male children with genu varus (age range 9–14 years) volunteered to participate in this study. They were randomly divided into 2 equal groups (experimental and control). The participants of the experimental group received CEC for 16 weeks. 3-D gait analysis involved using a Vicon Motion System. Paired and independent sample t-tests were used for within- and between-group comparisons, respectively.
Results
For the experimental group, comparison of pre- and post-test joint kinematics of the dominant lower limb revealed that CEC decreased the peak ankle dorsiflexion angle by 26% (P=0.020), peak foot internal rotation angle by 53% (P=0.001), peak knee internal rotation angle by 40% (P=0.011), peak hip abduction by 47% (P=0.010), and peak hip external rotation angle by 60% (P=0.001). In contrast, peak knee external rotation angle of the dominant limb was increased after the training program by 46% (P=0.044). For the non-dominant lower limb, CEC decreased the peak ankle inversion by 63% (P<0.01), peak ankle eversion by 91% (P<0.01), peak foot internal rotation by 50% (P<0.01), peak knee internal rotation by 29%; P=0.042), peak hip abduction angle by 38% (P<0.01), and peak hip external rotation angle by 60% (P<0.01).
Conclusions
CEC therapy reduced excessive foot and knee internal rotations as well as excessive hip external rotation during walking in children with genu varus.Permalink : ./index.php?lvl=notice_display&id=80459
