Better improvements of balance and complex gait were observed in elderly participants in tango lessons compared with a walking group. Beneficial effect of Argentine tango was also suggested, compared to traditional exercise for improving balance and functional mobility in patients with PD. Furthermore, a positron emission tomography (PET) study has shown increased activity in the basal ganglia when tango movements were performed with a metered and predictable beat. Tango requires particular motor skills, including frequent initiation and cessation, a variety of movement speeds, rhythmic variation, and spontaneous multidirectional perturbations. These features target motor impairments with movement initiation, turning, and bradykinesia. Interesting, tango could also effectively address freezing of gait (FOG), because some step patterns mimic the rehabilitation exercises designed for those with FOG. Visual cues, such as a foot to step over, can improve FOG. Tango technique which involve stepping over a partner's foot, tapping a partner's foot, or crossing one foot over another, are steps similar to conventional rehabilitation for FOG. In addition, tango involves rhythmic rocking, or alternating shift of center of mass from foot to foot, which can be another good strategy for freezing. Tango appeared to have a larger effect on freezing compared to other styles of dancing (waltz/foxtrot). Tango involves the practicing of control of movement speed and size, which may improve walking velocity and stride length. It also adds slow and quick steps of varying lengths and requires continual adjustment of these features. Tango may be especially beneficial for addressing backward walking, a critical area given the tendency for falls in the backward direction in PD6. Surprisingly in a recent study, tango even significantly improved upper extremity function, which it may be reflective of a global impact of exercise on bradykinesia. Better improvements of balance and complex gait were observed in elderly participants in tango lessons compared with a walking group. No studies have examined the effect of tango on cognitive function, mood and motivation in patients with PD.
