“…However, our results show few differences in stepping patterns according to turn direction; a finding that has also been reported in previous studies [5][6][7]. Given that the direction and extent of step asymmetry has been shown to vary according to age, motor recovery level and walking speed [26][27][28], systematic differences in stepping patterns according to the direction of the turn may be obscured by the complexity of relationships between these variables.…”

“…It has therefore been hypothesized [5] that falls during turning after stroke may not be due to an inability to produce movement patterns necessary to achieve a turn but due to cognitive-motor interference [12] (an inappropriate utilization of limited cognitive resources) which causes an exacerbation of motor impairments when additional cognitive demands are made.…”

Background:Although there is evidence that stroke survivors have reduced gait adaptability, the underlying mechanisms and the relationship to functional recovery are largely unknown. We explored the relationships between walking adaptability and clinical measures of balance, motor recovery and functional ability in stroke survivors. Methods:Stroke survivors (n=42) stepped to targets, on a 6m walkway, placed to elicit step lengthening, shortening and narrowing. The number of targets missed during six walks (3 targeting with paretic limb and 3 with non-paretic) and target stepping speed was recorded. Fugl-Meyer scores (FM), Berg Balance Scale (BBS), self-selected walking speed (SWWS) and single support (SS) and step length (SL) symmetry (using GaitRite when not walking to targets) were also assessed. Stepwise multiple-linear regression was used to model the relationships between: total targets missed, number missed with paretic and non-paretic legs, target stepping speed, and each clinical measure. Results:Regression revealed a significant model for each outcome variable that included only one independent variable. Targets missed by the paretic limb, was a significant predictor of FM(F(1,40)=6.54, p=0.014,). Speed of target stepping was a significant predictor of each of BBS(F(1,40)=26.36, p<0.0001), SSWS(F(1,40)=37.00, p<0.0001) and SS asymmetry (F(1,38)=5.57, p=.006). No variables were significant predictors of SL asymmetry. Discussion: Speed of target stepping was significantly predictive of SS symmetry, BBS and SSWS and paretic targets missed predicted FM, suggesting that fast target stepping requires good balance and temporal symmetry of gait and accurate stepping demands good paretic leg function. The relationships between these parameters indicate gait adaptability is a clinically meaningful target for measurement and treatment of functionally adaptive walking ability in stroke survivors.

“…Multiple steps were used as a turning strategy to increase both stability and balance during the turn. Stroke survivors do not use pivot strategy during 180̊ turn because they move in an "en bloc" pattern, which the body turns into one block in one direction (Hollands et al, 2010). The "en bloc" occurs as one block of body with their neck and trunk rigid, involving in multiple small steps to accomplish a turn rather than the usual twisting of the neck, trunk and pivoting on the toes (Verheyden, Willems, Ooms, & Nieuwboer, 2007).…”

Turning is an attentionally demanding task for stroke survivors especially when it involves challenging environments. The aim of this study was to investigate turning characteristics under dual-task conditions (dual motor and dual cognitive) in stroke survivors and healthy controls. We compared the turning characteristics based on the following: (1) staggering, (2) number of steps, (3) time was taken, and (4) strategy used to complete a 180º turn. We found that stroke survivors presented with turning difficulty, especially under dual cognitive task. Forthcoming research is needed to investigate further the social impact of stroke survival in their current environment.

Kinematics of Turning 180° During the Timed Up and Go in Stroke Survivors With and Without Falls History

Abstract: These results indicate incidences of falls during turning following stroke may not be due to impaired movement patterns but due to the many other factors that are associated with falls, such as deficits in cognitive processes--attention or central integration--and/or sensory deficits.
