Table 7 Mean values and standard error (SE) variables of spatiotemporal gait parameters in the FS in the DG and WG groups at the PRE and POST intervention moments; and the difference (p) regarding group, time and group*time interaction, Effect Size and Confidence Interval (IC)

From: Can Samba and Forró Brazilian rhythmic dance be more effective than walking in improving functional mobility and spatiotemporal gait parameters in patients with Parkinson’s disease?
