(Herman & Siegel, 2008) However, the tails of most vertebrates have more function than human’s tail, including maintaining of the center of gravity and balance when walking. Our motivation for the study is whether the human coccyx has any influence on performance of human balance or not. Purpose: Fist, whether coccydynia influences the performance of human balance. Second, if the ice packing therapy for patients with coccydynia improves the performance of human balance or not. Methods: We recruited 59 college students (age 19 to 25-year-old) who were all assessed by the same doctor and checked by the questionnaire of pelvic floor syndrome. There were 20 participants with coccydynia and 30 participants without coccydynia. Smart Balance Master System is used to test the balance performance, and MicroFET3 is used to measure the range of lumbar motion. First, we collect the assessing results of all participants. Second, we collect the assessing results of participants with coccydynia after ice packing for 15 minute. Results: To compare the balance performance and range of lumbar motion of participants with and without coccydynia, there are significant differences in condition 4 of Sensory Organization Test and ankle strategy 1 and 4, but no significant difference in Center Of Gravity, Limits Of Stability, Rhythmic Weight Shifting and ROM. Before and after ice packing for participants with coccydynia, significant differences are showed in condition 4 and 6 of Sensory Organization Test, ankle strategy 1, and forward Reation Test/Endpoint Excursions/Directional Control, left-side EPE and right-side DCL in LOS; not in COG and RWS. Conclusion: Our study shows that participants without coccydynia have better performance in some assessments of the static balance tests than those with coccydynia. Coccyx can cooperate with surrounding muscles and ligaments to help people to maintain dynamic balance. Ice packing to coccyx and surrounding tissues can relieve coccygeal pain and inflammation. So that, participants with coccydynia have better performance in forward reaction time, direction control and end point excursion after ice packing. Therefore, ice packing may improve some balance ability related with coccyx.
