New JAB research shows that windup and stretch deliveries share more similarities than differences, though the windup produces higher trunk and arm velocities. The stretch delivery may slightly reduce shoulder loading.

New JAB research shows that IMUs detect slip perturbations at amplitudes far below conscious perception, with EMG revealing reflex‑level responses as well. These thresholds support future screening for instability in clinical and real‑world settings.

🚶♀️🧠 New JAB research shows that dual‑task walking alters step length, width, and stability, but these changes do not align with Dynamic Gait Index scores. Dual‑task cost appears more sensitive to subtle cognitive–motor changes.

New JAB research shows that people with knee OA who walk with symmetrical knee loading report worse function and display gait patterns linked to more severe OA. Symmetry may signal reduced compensatory capacity rather than recovery.

New JAB research shows that a constrained hallway markerless setup produces joint‑angle estimates highly comparable to a traditional lab, especially for standing and walking. Even sit‑to‑stand remained reliable across sites!

New JAB research shows that force production is still not fully recovered 48 hours after intense knee exercise, with vastus lateralis motor unit behavior closely tied to force loss and recovery. 🦵💪🏋️

We'd like to introduce you to Kári Árnason, an emerging researcher & Asst Prof at the University of Iceland.
His recently published JAB article highlights the contribution of pelvis rotation & hip kinematics to the shoulder kinematics during a handball jump throw.
