Upper part, left side: Fahn-Tolosa-Marin Tremor Rating Scale (FTMTRS) scores at T1 (June 2015), T2 (December 2020, before SARS-CoV-2 infection), and T3 (July 2021, after SARS-CoV-2 infection). Diamonds indicate total FTMTRS scores; triangles indicate section A subscores; squares indicate section B subscores; circles indicate section C subscores. Upper part, right side: postural tremor amplitude (average from the right and left upper limbs), expressed in terms of root mean square (RMS) of the acceleration traces of the reference marker in 3D space (GRMS^2), as kinematically assessed at T1, T2, and T3, during posture 1 (P1) (arms outstretched, represented by diamonds) and posture 2 (P2) (“wing beating,” represented by squares). Triangles indicate mean tremor amplitude values recorded during P1 and P2. Middle part: spiral drawing at T1, T2, and T3. Lower part: kinematic acceleration frames on the y-axis (15-s duration) recorded from the reflective marker placed on the left index finger of the patient while maintaining P1. Black solid lines represent kinematic recordings performed at T1. Black dashed lines and light gray lines represent kinematic recordings performed at T2 and T3 respectively
