Article Title: Multi-session adaptation to audiovisual and sensorimotor biofeedback is heterogeneous among adolescents with cerebral palsy

doi: 10.1371/journal.pone.0313617

Figure Lengend Snippet: Participants completed a four-day protocol using combined audiovisual and sensorimotor biofeedback. Audiovisual biofeedback on soleus activity was provided unilaterally on the more-affected limb whereas sensorimotor biofeedback was administered bilaterally using a resistive ankle exoskeleton. Each session was separated into baseline (1 minute), biofeedback (2, 10-minute bouts), and washout (1 minute) phases. The nominal torque value of the ankle exoskeleton was set at 0.1 Nm/kg during the first bout of the first session and incrementally adjusted by 0.025 Nm/kg over the subsequent bouts, according to the schedule shown. Overground walking data were collected pre- and post-intervention. A licensed physical therapist also performed a full physical examination at the pre-intervention session. Motion capture data were collected during at the pre- and post-intervention sessions and electromyography (EMG) data were collected bilaterally from the vastus lateralis, semitendinosus, soleus, and tibialis anterior across all sessions.

Article Snippet: Bilateral surface electromyography (EMG) data were recorded for the tibialis anterior (TA), medial gastrocnemius (GAS), vastus lateralis (VL), and semitendinosus (ST) across all sessions (Noraxon; Scottsdale, AZ; 1000 Hz).

(D) Comparison of MFS within and between groups at the time of intensive care unit (ICU) discharge (18.00 ± 10.19 days) from baseline; severity is proportional to high score. P-value and Cohen’s d effect size are noted from time group interaction at each determined time point.

Article Title: Neuromuscular Compensation Strategies Adopted at the Shoulder Following Bilateral Subpectoral Implant Breast Reconstruction

doi: 10.1016/j.jbiomech.2021.110348

Figure Lengend Snippet: Surface electromyography data were obtained from sixteen shoulder muscles while participants generated eight 3D isometric shoulder torques in five two-dimensional arm postures bilaterally. On the dominant arm, only upper trapezius activity differed between the groups (A). On the non-dominant arm, the sternocostal fiber region of the PM and upper trapezius activity differed between the groups (B). Bars represent mean ± standard error. Significant differences are visualized by colored bars and * signifies a significant group difference at p < 0.05.
