Balance Stability

Individuals with incomplete spinal cord injuries (iSCI) often experience impairments in motor control of lower-limb muscles, causing a lack of balance when standing. These individuals are usually heavily dependent on others, reducing their self-sufficiency and quality of life. Our previous study has shown that visual feedback training (VFT) of tracking an individual’s center of pressure (COP) can improve balance stability of those with iSCI (1). Another of our previous studies demonstrated that functional electrical stimulation (FES) augments therapeutic effects in general (2-8). Thus, VFT in combination with FES is hypothesized to improve the standing balance ability of individuals with iSCI more effectively than a VFT or FES system. The purpose of this study was to develop a novel therapeutic system by combining VFT with FES. We developed this system by utilizing LabVIEW (17.0, National Instruments Corp., Austin, USA). The system hardware consisted of a force plate, an electrical stimulator, and a computer. The COP was calculated using the force plate signals, which was displayed in the monitor in front of the participant. We developed four COP-based games, each forcing the participant to shift their COP in various movement patterns. FES will provide electrical stimulation to participant plantarflexors and dorsiflexors to assist with movements, in which stimulus intensity will be modulated through a proportionalderivative (PD) feedback controller that mimics the physiological control system for standing (9,10). In this study, we tested the practicality of our VFT games with seven able-bodied participants (age 19-24 years). Each participant performed a balance assessment before playing the VFT games to determine their balance ability. Our focus was on developing effective VFT games and assessing each participant’s balance ability against their VFT game scores. Three out of four games showed a significant bivariate correlation between balance ability and VFT scores (r > 0.754 for n=7), indicating that the games were appropriately designed. The validity of the FES controller was demonstrated in another study to be effective. The parameters of the PD controller were optimized so that the stimulation intensity would match the natural muscle contraction of the plantarflexors and dorsiflexors, acquired through electromyography (EMG) signals. It is expected that rehabilitation combining VFT with FES will improve static and dynamic balance stability in a more effective way than isolated therapy techniques. Since this study has shown the validity of our VFT games, we would like to integrate the VFT and FES systems and run clinical trials on patients with iSCI, with the goal of improving their balance ability in the future. Through visual feedback training, the brain improves spatial awareness by visualizing their body displacement and orientation. Applying stimulation to the muscles re-trains the central nervous system and, over time, allows patients with iSCI to partially regain motor control. Thus, the proposed system will help individuals with iSCI improve their balance ability and increase their quality of life.

Purpose Among the best strategies to address inadequate speech monitoring skills and other parameters of communication in people with cluttering (PWC) is the relatively new but very promising auditory–visual feedback (AVF) training ( van Zaalen & Reichel, 2015 ). This study examines the effects of AVF training on articulatory accuracy, pause duration, frequency, and type of disfluencies of PWC, as well as on the emotional and cognitive aspects that may be present in clients with this communication disorder ( Reichel, 2010 ; van Zaalen & Reichel, 2015 ). Methods In this study, 12 male adolescents and adults—6 with phonological and 6 with syntactic cluttering—were provided with weekly AVF training for 12 weeks, with a 3-month follow-up. Data was gathered on baseline (T0), Week 6 (T1), Week 12 (T2), and after follow-up (T3). Spontaneous speech was recorded and analyzed by using digital audio-recording and speech analysis software known as Praat ( Boersma & Weenink, 2017 ). Results The results of this study indicated that PWC demonstrated significant improvements in articulatory rate measurements and in pause duration following the AVF training. In addition, the PWC in the study reported positive effects on their ability to retell a story and to speak in more complete sentences. PWC felt better about formulating their ideas and were more satisfied with their interactions with people around them. Conclusions The AVF training was found to be an effective approach for improving monitoring skills of PWC with both quantitative and qualitative benefits in the behavioral, cognitive, emotional, and social domains of communication.

Background and Objectives: The purpose of this study was to investigate the correlation between the Korean version of the trunk control measurement scale (K-TCMS) and the selective control assessment of the lower extremity (SCALE). Through this, we tried to find out the effect of proximal stabilization on distal motor development. Materials and Methods: Fifty-one children with gross motor function classification system level I–III, diagnosed with cerebral palsy (CP), were studied. The K-TCMS was used to evaluate the body control ability of the children. SCALE was used to quantify selective voluntary motor control (SVMC). Results: Analysis of SCALE and K-TCMS showed a significant positive correlation in all items. Multiple regression analysis showed that the SCALE score decreased as age increased, and that it increased as the static sitting balance ability score and the dynamic sitting balance ability score of the K-TCMS increased significantly (p < 0.05). Conclusions: In children with cerebral palsy, there was a close correlation between trunk control and selective voluntary motor control of the lower extremities. Therefore, when trying to improve the lower extremity function of a child with cerebral palsy, a trunk control intervention should be considered.
