Improvements of pliability (a), pain (b), pruritus (c) and paresthesia (d) as scored by the UNC4P before and after AFCL and AFCL+PRP treatment. After 6 months treatment, the pliability (a), pain (b), pruritus (c) and paresthesia (d) scores on the UNC4P in the AFCL+PRP group were reduced by 0.81 ± 0.07, 1.61 ± 0.12, 1.97 ± 0.10 and 1.26 ± 0.10, respectively, resulting in significantly lower scores than that in the AFCL group (0.21 ± 0.10, 0.95 ± 0.14, 1.26 ± 0.15 and 0.63 ± 0.14, respectively; p < 0.05). ^*p < 0.05, MannWhitney U test.
