Abstract:

Objective To evaluate the reliability of Foot Posture Index (FPI-6) for Chinese adolescent idiopathic scoliosis (AIS) patients.

Methods From July, 2021 to April, 2022, 35 AIS patients were recruited from Guangdong Second Hospital of Traditional Chinese Medicine and non-specially. They were evaluated with FPI-6 by two raters on the same days, and by one of the raters a week later. The intra-class correlation coefficient (ICC) of inter-rater and test-retest was calculated and Bland-Altman diagram was drawn; the correlation among the items score and total score was analyzed with Spearman correlation coefficient.

Results The ICCs were above 0.75 except talar head palpation, and eversion and inversion of the calcaneus. There was no significant difference in foot posture classification among the three evaluation results (χ2 = 4.000, P >0.05). There was a significant positive correlation between each item score and total score (r > 0.3, P < 0.01).

Conclusion FPI-6 is reliable for people with mild AIS.
