Hand Passive Mobilization Performed with Robotic Assistance: Acute Effects on Upper Limb Perfusion and Spasticity in Stroke Survivors

Figure 2

Signal analysis of the total haemoglobin (THb) profile. Panel (a) shows the THb profile acquired during a whole treatment session from a representative subject. Time windows corresponding to the duration of each passive movement modality were selected (panel (b)). For each time window, the values corresponding to the largest variation of THb dynamics were averaged (panel (c)) in order to obtain the delta value (ΔTHb) for each of the administered treatment modalities.
