Far-Infrared Therapy Promotes Nerve Repair following End-to-End Neurorrhaphy in Rat Models of Sciatic Nerve Injury

Table 1

Weight-change percentage of all rats during the experimental period.

Implantation time	NI/sham	NI/FIR	Normal
2 weeks	14.87 ± 4.10	15.58 ± 2.60	16.57 ± 1.41
4 weeks	16.92 ± 3.99	20.50 ± 1.38	20.52 ± 2.38
6 weeks	23.36 ± 4.90	29.13 ± 2.98	30.15 ± 3.65^*
8 weeks	28.38 ± 3.24	36.88 ± 3.96^*	36.29 ± 4.85^*

Significantly (P < 0.05) greater than NI/sham group at the same surgical time.
