Assessment of arousal recovery after cardiac arrest using diffusion kurtosis MRI with higher b-values: a pilot study.

Objective: Comatose survivors of cardiac arrest (CA) pose a complex challenge for physicians reliant on imperfect studies to determine the extent of neurologic injury. Clinically available imaging is frequently relied upon despite limited sensitivity. We conducted a prospective pilot study comparing diffusion kurtosis imaging (DKI)-MRI and somatosensory evoked potentials (SSEPs) in comatose survivors of CA to investigate the benefit of utilizing higher diffusion b-values to enhance prediction of arousal recovery.

Role of joint interactions in upper limb joint movements: a disability simulation study using wearable inertial sensors for 3D motion capture.

Background: Restriction of movement at a joint due to disease or dysfunction can alter the range of motion (ROM) at other joints due to joint interactions. In this paper, we quantify the extent to which joint restrictions impact upper limb joint movements by conducting a disability simulation study that used wearable inertial sensors for three-dimensional (3D) motion capture.

Methods: We employed the Wearable Inertial Sensors for Exergames (WISE) system for assessing the ROM at the shoulder (flexion-extension, abduction-adduction, and internal-external rotation), elbow (flexion-extension), and forearm (pronation-supination).
