“…The Timed Up and Go test (Podsiadlo and Richardson 1991) and timed 10 m Walk test were used to assess over-ground walking mobility, speed, and endurance. The Timed Up and Go test, in addition to the extra demand of standing from a seated position, also required unique demands on neural processes involved in the control of medial–lateral stability for the purpose of turning around which are not required for the 10 m Walk test (Chisholm et al 2015). The same individual, to limit inter-rater variability, performed all clinical walking tests.…”

Spasticity of the ankle reduces quality of life by impeding walking and other activities of daily living. Robot-driven continuous passive movement (CPM) is a strategy for lower limb spasticity management but effects on spasticity, walking ability and spinal cord excitability (SCE) are unknown. The objectives of this experiment were to evaluate (1) acute changes in SCE induced by 30 min of CPM at the ankle joint, in individuals without neurological impairment and those with lower limb spasticity; and, (2) the effects of 6 weeks of CPM training on SCE, spasticity and walking ability in those with lower limb spasticity. SCE was assessed using soleus Hoffmann (H-) reflexes, collected prior to and immediately after CPM for acute assessments, whereas a multiple baseline repeated measures design assessed changes following 18 CPM sessions. Spasticity and walking ability were assessed using the Modified Ashworth Scale, the 10 m Walk test, and the Timed Up and Go test. Twenty-one neurologically intact and nine participants with spasticity (various neurological conditions) were recruited. In the neurologically intact group, CPM caused bi-directional modulation of H-reflexes creating ‘facilitation’ and ‘suppression’ groups. In contrast, amongst participants with spasticity, acute CPM facilitated H-reflexes. After CPM training, H-reflex excitability on both the more-affected and less-affected sides was reduced; on the more affected side H@Thres, H@50 and H@100 all significantly decreased following CPM training by 96.5 ± 7.7%, 90.9 ± 9.2%, and 62.9 ± 21.1%, respectively. After training there were modest improvements in walking and clinical measures of spasticity for some participants. We conclude that CPM of the ankle can significantly alter SCE. The use of CPM in those with spasticity can provide a temporary period of improved walking, but efficacy of treatment remains unknown.

“…Nine studies measured turning on the spot[10, 20, 37, 41, 46, 48, 52, 66, 67], three studies were radius circle or semicircle[33, 36, 57]. The maximum and average length of approach path was 7 m and 3.33 m, respectively.…”

“…The maximum and average length of approach path was 7 m and 3.33 m, respectively. Turn direction was set for both sides in 26 studies[9, 10, 27, 33, 34, 36, 37, 39-41, 45-49, 51, 52, 54, 56, 57, 62, 64-66, 68, 69], and 16 studies limited either side[11, 19, 20, 29, 32, 35, 38, 42-44, 59-61, 67, 70, 71]. The formalized task was only TUG with 7 studies[11, 28, 30, 40, 58, 62, 63], 11 studies including instrumented TUG[50, 55, 59, 68].…”

Background: Patients with nervous system and musculoskeletal diseases display gait disturbance that is a leading cause of falls. Identification of disease-specific movement hallmarks is therefore an essential first step in preventing falls. Since turning, a common daily activity, is a unique movement that requires inter-limb spatial coordination, turning may be a suitable observational target for the identification of disease-specific movement disorder. However, to date, few comprehensive systematic review regarding disease-specific alterations in turning movement is available. Research question: This systematic review with meta-analysis summarized the level of knowledge regarding movement disorders during turning in patients with nervous system and musculoskeletal diseases. Methods: A systematic review was conducted of papers throughout 2021 in accordance with PRISMA guideline. Including criteria were (1) were published in a peer-reviewed journal, (2) were written in English, (3) included adult patients who were diagnosed with musculoskeletal or nervous system diseases, (4) had a control group of age-matched healthy adults, and (5) outcomes included turning parameters. Results: Meta-analysis revealed a significantly larger step number, longer turn duration, and shorter step length in patients with Parkinson's disease (PD) than in controls during the 180 degree turn, suggesting that these biomechanical alterations may be, at least in part, movement disorders associated with PD. Notably, this review identified methodological heterogeneity for turning movement assessments, which limited the identification of disease-specific movement disorders. Significance: This work serves as a call to action for the establishment of a standard assessment protocol towards the identification of disease-specific turning movement disorders and effective disease screening.

“…However, a previous study reported that walking along a curved path implies a different spatiotemporal parameter of muscle activation compared with straight walking in humans [16][17][18][19]. After the studies, several researchers have reported on curved walking in hemiparetic individuals [20][21][22].…”

“…Godi et al [20] reported the velocity of curved walking was not significantly smaller in hemiparetic patients compared with linear walking. Two other studies examined the neuromuscular strategies in the paretic leg during curved walking for persons with stroke [21,22]. Indeed, there is a lack of studies comparing linear walking and curved path walking in stroke surivors.…”

The purpose of this study was to compare walking conditions (straight line and curved path) on walking patterns in persons who had experienced hemiplegic stroke and to determine whether if they adapt their walking pattern and performances according to changes in environmental conditions. Design: Cross-sectional study. Methods: Forty-four hemiplegic stroke survivors participated in this study. This study measured walking performance in three different walking conditions, such as straight walking, the more-affected leg in the inner curve walking, and less-affected leg in the inner curve walking conditions, and a 2-dimentional gait analysis system was used as a primary measurement. This study also measured secondary clinical factors including the Timed Up-and-Go Test, the Trunk Impairment Scale, and the Dynamic Gait Index. Results: After analyzing, cadence and step length of the less-affected side, stride length in the more-affected side, and stride length in less-affected side were significantly different among the three different walking conditions in this study (p<0.05), but other temporospatial parameters were not significant. Cadence was the largest in the straight walking condition. Step length in the less-affected side, stride length in the more-affected side, and stride length in less-affected side were also the longest in the straight walking condition. Conclusions: The results of the study suggest that hemiplegic stroke survivors show walking adaptability according to changes in walking demands and conditions, and moreover, cadence and step and stride lengths were significantly different between straight and curved walking conditions.
