Phase 2 - propulsion	0.33	0.39	0.19	0.15	0.75	0.56	0.34	0.96	0.72	1.10
Phase 3 - pelvic balance	0.21	0.15	0.05	0.16	0.32	0.10	0.11	0.31	0.25	0.43
Phase 4 - swing	0.46	0.23	0.39	0.14	0.13	0.53	0.50	0.44	0.62	0.56
Phase 5 - support	0.05	0.35	0.08	0.15	0.35	0.42	0.26	0.42	0.63	0.63
Total score	0.29	0.38	0.18	0.19	0.59	0.51	0.36	0.74	0.70	0.89

Coefficients >0.20 and <0.50 indicate low responsiveness, coefficients >0.5 and <0.8 indicate moderate responsiveness, and coefficients >0.8 denote high responsiveness.
