“…The weekly frequency of the physiotherapy sessions ranged from 1 to 6 days/week, and the total duration of the rehabilitative program ranged from 2 to 16 weeks. MRI was always acquired both before and at the end of the rehabilitative cycle, whereas in 5 studies there was also an additional MRI time-point, either within the cycle (Prosperini et al, 2014;Kjolhede et al, 2018), after 4 weeks (Akbar et al, 2020;Prochazkova et al, 2020), or after 3 months (Tavazzi et al, 2018). Among the 17 selected studies, 5 applied structural MRI [4 diffusion tensor imaging (DTI) (Ibrahim et al, 2011;Bonzano et al, 2014;Prosperini et al, 2014;Barghi et al, 2018), 1 volumetric measurements (Kjolhede et al, 2018)], 7 applied functional fMRI [5 task-related fMRI (Rasova et al, 2005;Bonzano et al, 2019;Peran et al, 2020;Prochazkova et al, 2020;Zuber et al, 2020)], 2 resting-state fMRI (Fling et al, 2019;Akbar et al, 2020) whereas the remaining 5 applied both structural and functional imaging (Rasova et al, 2015;Tavazzi et al, 2018;Rocca et al, 2019;Boffa et al, 2020;Stellmann et al, 2020).…”
