Objective To translate the Water Orientation Test of Alyn 2 (WOTA2) into Chinese, and to study its reliability and validity for patients with spinal cord injury. Methods After authorizing, the English version WOTA2 scale and its training package were translated into Chinese. From January to September, 2018, 137 patients with spinal cord injury were evaluated with the Chinese version WOTA2 by two evaluators independently, and evaluated again three days later by one of the evaluators. The Cronbach's α, Spearman-Brown coefficient, intra-group correlation coefficient (ICC) and Kappa coefficient were calculated to evaluate the reliability. Content Validity Index (CVI) of items (I-CVI) and scale (S-CVI) were used to evaluate the content validity, and factors analysis was used to evaluate the structure validity. Results The Cronbach's α was 0.947 in all items of the scale, 0.890 in mental adjustment items and 0.954 in aquatic skills items. Pearson correlation coefficient of the half scales separated by odd and even items was 0.948, and the Spearman-Brown coefficient was 0.973. The ICC of test-retest was 0.965 in total score, 0.965 in centesimal system total score, 0.847 in mental adjustment score and 0.970 in aquatic skills score. The ICC of inter-testers was 0.964 in total score, 0.965 in centesimal system total score, 0.847 in mental adjustment score and 0.970 in aquatic skills score. The Kappa coefficient was 0.528 to 0.927 in test-retest and 0.528 to 0.927 in inter-testers. The I-CVI was 0.8 to 1.0 and S-CVI was 0.63. Factors analysis extracted four factors, which met the theory, and contributed 67% of cumulative variance. Conclusion The Chinese version WOTA2 is good in reliability and validity for patients with spinal cord injury, and can be used in the clinical practice of aquatic therapeutic exercise in China.

Objective To observe the effects of Traditional Chinese Medicine bubble bath on the children with spastic diplegia cerebral palsy. Methods 13 children with spastic diplegia cerebral palsy received routine rehabilitation and bubble bath (control group), while 14 children received routine rehabilitation and Traditional Chinese Medicine bubble bath (experimental group). All the children were assessed with Gross Motor Function Measure (GMFM-66) and Modified Ashworth Scale (MAS) of triceps surae muscle before and 10 weeks after treatment.Results The total score of GMFM-66 increased (P<0.001) and the MAS score decreased in both groups (P<0.01) after treatment. The dimensions B, D, and E of GMFM-66 only increased in the experimental group (P<0.05). The MAS score decreased more in the experimental group than in the control group after treatment (P<0.05). Conclusion Traditional Chinese Medicine bubble bath can improve gross motor function and reduce triceps surae muscle tension of the children with spastic diplegia cerebral palsy.
