The correlation analysis showed significant positive correlation only between the music ΔPU and ΔTUG (r = 0.63, p = 0.007) suggesting that when the patients reported less PU, they were also faster at the TUG task for functional mobility (Figure (Figure4).4). There were also significant positive correlations between age and music: ΔPI (r = 0.61, p = 0.007) and ΔPU (r = 0.61, p = 0.009). This means that the older the patient the higher analgesic effect reported. Interestingly, there was no correlation between “age” and control ΔPI nor ΔPU.
