Prognostic value of cortically induced motor evoked activity by TMS in chronic stroke: Caveats from a revealing single clinical case

Table 2 Frequency and NIV of different diadochokinetic movements measured using a 3D ultrasound movement analysing device

Task	Pronation/Supination (PS)	Hand Tapping (HT)	Finger Tapping (FT)
Frequency Affected (FREQ)	1.5 (0.4)	3 (0.3)	2.4 (0.1)
Frequency Unaffected (FREQ)	3.4 (0.5)	2.9 (0.2)	3.6 (0.3)
Δ FREQ	1.9	−0.1	1.2
NIV Affected	1.2 (0.2)	1.6 (0.2)	1.1 (0.02)
NIV Unaffected	1.2 (0.3)	1 (0)	1 (0)
Δ NIV	0	0.6	0.1

Absolute differences (Δ FREQ, Δ NIV) in both parameters for each task between the affected (Right) and the unaffected (Left) hand are shown. Values are showed as mean (std). Slight differences for FREQ in HT and for the NIV in FT and PS indicate the good performance of the motor tasks with the affected hand compared with the unaffected.
