Comparisons of forward and backward gait between poorer and better attention capabilities in early Parkinson's disease

Loss of gait control assessed by cognitive-motor dual-tasks: pros and cons in detecting people at risk of developing Alzheimer’s and Parkinson’s diseases

“…Such disorders include (i) decreases in gait speed (Fuller et al 2013;Wild et al 2013;Stegemöller et al 2014;Strouwen et al 2016), stride length (O'Shea et al 2002;Rochester et al 2004;Plotnik et al 2011; (Plotnik et al 2009;Tseng et al 2012;Vervoort et al 2016) and (ii) increases in stride time (Panyakaew and Bhidayasiri 2013;Stegemöller et al 2014), cadence (Rochester et al 2014), stance time (Wild et al 2013), stride width (Stegemöller et al 2014), stride length asymmetry (Rochester et al 2014;Vervoort et al 2016), swing time variability (Stegemöller et al 2014), stride time variability, and stride length variability Yogev et al 2007;Plotnik et al 2009Plotnik et al , 2011Yogev-Seligmann et al 2012;Rochester et al 2014;Stegemöller et al 2014). Decreases in arm swing amplitude and increases in both arm swing asymmetry and arm swing variability have also been documented (Mirelman et al 2016).…”

Treadmill Training Improves Forward and Backward Gait in Early Parkinson Disease

“…Backward walking (BW) gait in PD patients compared with healthy elderly subjects is much worse than forward walking (FW) gait. 3,4 When compared with agematched healthy elderly subjects, PD patients walk more slowly in forward and backward directions with shorter stride length, lesser swing phase, and longer double support phase. 3,4 FW and BW cadences may remain unchanged when compared between PD patients and age-matched healthy people.…”

“…3,4 When compared with agematched healthy elderly subjects, PD patients walk more slowly in forward and backward directions with shorter stride length, lesser swing phase, and longer double support phase. 3,4 FW and BW cadences may remain unchanged when compared between PD patients and age-matched healthy people. 3,4 The forward cadence, however, may also be slightly elevated to compensate for a shorter stride length in moderate PD.…”

Dual task performance: a comparison between healthy elderly individuals and those with Parkinson’s disease

“…Therefore, dual tasking is an appropriate strategy to improve gait, while the use of different types of secondary tasks is an alternative that may potentially lead to good results. Tseng and collaborators found similar results when they compared the performance of patients with PD while walking backwards (30). Studies also suggest that the assessment of the ability to perform two tasks simultaneously may be a sensitive indicator of incapacity among individuals with PD, even in the initial phases of the disease.…”
