Background: Both of transcranial direct current electrical stimulation (tDCS) and neuromuscular training (NMT) have used to relive motor deficits in neurological disease.Aim: We decided to investigate augmenting effect of tDCS and NMT to improve static and dynamic balance and gait parameter in autism spectrum disorder (ASD).Materials and Methods: 24 children with ASD aged 6-10 years old were randomly assigned to one of three groups: NMT+ sham, anodal tDCS, and NMT + tDCS. NMT consisted of 10 sessions motor training (each for 40 min). tDCS training was performed with 1.5 mA on left primary motor cortex for 20 min. Pre-test and post-test evaluations included static and dynamic balance and gait parameters (length and width of stepping and speed of gait).Results: Although improvement of variables were seen in all groups, but in post intervention comparison, combined group was better in static and dynamic balance and gait parameters than two other groups. NMT was more effective than tDCS only in dynamic balance.Conclusion: Our findings were indicated tDCS enhance NMT effect on neuromuscular function in ASD, so regarding the augmented effect in combination of NMT and tDCS, it can be considered in rehabilitation of motor deficits in these children.

Background: Losing a limb can negatively impact balance and gait, leading to reduced quality of life.Aim: This study aimed to examine correlations between spatiotemporal gait and balance with scores of the Quality of Life questionnaire.Materials and Methods: 30 veterans with unilateral below-knee amputations underwent gait analysis to measure step length, stride length, stance time, cadence, velocity, and walking symmetry index by step length. Static balance was assessed via the center of pressure path length by Wii Balance Board during standing. The Timed Up and Go test evaluated dynamic balance. The QoL scores were recorded using the Quality of Life questionnaire for amputees, Trinity Amputation, and Prosthesis Experience Scales (TAPES). Pearson’s correlation coefficients were calculated between spatiotemporal of gait, balance scores, and TAPES domain outcomes.Results: Stride length (r=0.660), prosthetic step length (r=0.648) and intact step length (r=0.618) showed significant moderate positive correlations with psychosocial adjustment, while amputation limb stance time (r=-0.409) correlated weakly. Activity limitations negatively correlated with step/stride lengths (r range -0.781 to -0.784) and cadence (r=-0.538). Moreover, prosthesis satisfaction was associated with improved walking symmetry (r=0.445) and prosthetic stance time (r=0.388).Conclusion: Optimizing gait and balance in below-knee amputation can improve quality of life. Biomechanical factors should be targeted in rehab programs to enhance well-being.
