“…An effective treatment for AMI includes biofeedback therapy (34,35). Most of the reports are based on electromyographic biofeedback, which measures the electrical activity of the muscle from the electrodes attached to the skin surface and feeds back the magnitude of the muscle activity visually and auditorily (36)(37)(38)(39)(40)(41).…”

Introduction: Elderly people often exhibit "frailty," and motor dysfunction occurs. Several studies have reported about the relationship between motor dysfunction and frailty in Parkinson's disease (PD). This study aimed to test whether the core exercise using the hybrid assistive limb lumbar type for care support (HAL-CB02) may improve the motor functions in frailty patients with or without PD and to explore the optimal patient selection from the frailty cohort. Materials and Methods: We recruited 16 frailty patients (PD = 8; non-PD = 8). The participants performed core exercise and squats using HAL-CB02 for five sessions a week. Outcome measures were 10-m walking test, step length, timed up-and-go test, 30-s chair stand test, and visual analog scale. Evaluation was conducted at baseline, post-exercise, and 1-and 3-month follow-ups. Results: Both PD and non-PD patients showed significant improvement in all evaluation items post-exercise. Moreover, no significant difference was found in the improvement value between the two groups. Conclusions: Our results suggest that biofeedback exercise with HAL-CB02 is a safe and promising treatment for frailty patients. Motor dysfunction in PD patients may be partly due to physical frailty, and biofeedback exercise with HAL-CB02 is proposed as a treatment option.

Anterior cruciate ligament (ACL) reconstruction is a common and predominantly successful surgical intervention. But are there specific preoperative patient characteristics or intraoperative surgeon decisions that lead to better or worse outcomes? And can understanding brain function changes of patients after ACL reconstruction reveal insights into the ways that postsurgical rehabilitation can be improved to further enhance outcomes? These intriguing and clinically applicable questions are addressed in this webinar titled "Improving ACL Reconstruction Outcomes," hosted jointly by JOSPT and JBJS. The webinar is based on 2 published research articles-one from JBJS and the other from JOSPT. Participants in this continuing education activity are asked to read both articles carefully before watching the webinar. JBJS co-author Kurt Spindler, MD, discusses findings from a longitudinal analysis that identified certain baseline patient characteristics and intraoperative choices that predicted higher and lower SF-36 Physical Component scores after ACL reconstruction. JOSPT co-author Dustin Grooms, PhD, ATC, shares recently published results of a controlled laboratory study that employed functional MRI to investigate brain-activation differences between patients who did and did not undergo ACL reconstruction. Moderated by Kevin Wilk, PT, DPT, FAPTA, a leading authority on rehabilitation of sports injuries, the webinar includes additional insights from expert commentators Eric McCarty, MD, and Karin Grävare Silbernagel, PT, PhD, ATC.

“…Arms with greater overall corticomotor excitability could generate greater maximum moments during isometric elbow extension. Thus, rehabilitative strategies to increase corticomotor excitability, (e.g., repetitive TMS, 20 EMG biofeedback, 21 anodal transcranial direct stimulation 22 ) may be beneficial for elbow extension strength.…”

Background Following biceps transfer to enable elbow extension in individuals with tetraplegia, motor re-education may be facilitated by greater corticomotor excitability. Arm posture modulates corticomotor excitability of the nonimpaired biceps. If arm posture also modulates excitability of the transferred biceps, posture may aid in motor re-education. Objective Our objective was to determine whether multi-joint arm posture affects corticomotor excitability of the transferred biceps similar to the nonimpaired biceps. We also aimed to determine whether corticomotor excitability of the transferred biceps is related to elbow extension strength and muscle length. Methods Corticomotor excitability was assessed in seven arms of individuals with tetraplegia and biceps transfer using transcranial magnetic stimulation (TMS) and compared to biceps excitability of nonimpaired individuals. Single-pulse TMS was delivered to the motor cortex with the arm in functional postures at rest. Motor evoked potential (MEP) amplitude was recorded via surface electromyography. Elbow moment was recorded during maximum isometric extension trials and muscle length was estimated using a biomechanical model. Results Arm posture modulated corticomotor excitability of the transferred biceps differently than the nonimpaired biceps. Elbow extension strength was positively related and muscle length was unrelated, respectively, to MEP amplitude across the arms with biceps transfer. Conclusions Corticomotor excitability of the transferred biceps is modulated by arm posture and may contribute to strength outcomes after tendon transfer. Future work should determine whether modulating corticomotor excitability via posture promotes motor re-education during the rehabilitative period following surgery.
