Figure 3: Effects of massage on zALFF values in a peripheral nerve injury rat. zALFF values in rat cortex were analyzed by one-way analysis of variance followed by post hoc two-sample t-test. Normal: Naïve rats without intervention; Model: right sciatic nerve transection and immediate repair; Sham massage: right sciatic nerve transection and repair and 4-week sham-massage intervention; Massage: right sciatic nerve transection and immediate repair and 4-week massage over the right gastrocnemius muscle. Values are expressed as the mean. Error bars are the SD. zALFF: Fisher's z transformation amplitude of low-frequency fluctuations.
