“…Few studies have evaluated the relationship between fear of falling and step length in stroke. Park et al showed that fear of falling was related to step cycle while walking but not to step length in only 12 stroke subjects, which contrasts with the present results [ 43 ]. However, many studies in elderly subjects have also demonstrated a relationship between fear of falling and decreased step length [ 44 , 45 , 46 ].…”

BackgroundThe timed up and go test (TUG) is a functional test which is increasingly used to evaluate patients with stroke. The outcome measured is usually global TUG performance-time. Assessment of spatiotemporal and kinematic parameters during the Oriented gait and Turn sub-tasks of the TUG would provide a better understanding of the mechanisms underlying patients’ performance and therefore may help to guide rehabilitation. The aim of this study was thus to determine the spatiotemporal and kinematic parameters which were most related to the walking and turning sub-tasks of TUG performance in stroke patients.Methods29 stroke patients carried out the TUG test which was recorded using an optoelectronic system in two conditions: spontaneous and standardized condition (standardized foot position and instructed to turn towards the paretic side). They also underwent a clinical assessment. Stepwise regression was used to determine the parameters most related to Oriented gait and Turn sub-tasks. Relationships between explanatory parameters of Oriented gait and Turn performance and clinical scales were evaluated using Spearman correlations.ResultsStep length and cadence explained 82% to 95% of the variance for the walking sub-tasks in both conditions. Percentage single support phase and contralateral swing phase (depending on the condition) respectively explained 27% and 56% of the variance during the turning sub-task in the spontaneous and standardized conditions.Discussion and ConclusionStep length, cadence, percentage of paretic single support phase and non-paretic swing phase, as well as dynamic stability were the main parameters related to TUG performance and they should be targeted in rehabilitation.

“…In a few studies using a treadmill, speed-increase training has been considered a beneficial approach for improving the gait speed on ground to a greater extent than traditional programs that train at slower speeds in patients with stroke16,17,18 ) . Some stroke patients are afraid of falling because of gait and balance impairments19 ) . In addition to the assistive function of the HAL device described above, a walking device (All-In-One Walking Trainer) with a harness would enable performance of high-speed gait training without the risk of falling.…”

Sustained effects of once-a-week gait training with hybrid assistive limb for rehabilitation in chronic stroke: case study

2016

[Purpose] The purpose of this study was to investigate the accumulated and sustained effects of once-a-week gait training with a powered exoskeleton suit, Hybrid Assistive Limb, in a subject with chronic stroke. [Subject and Methods] The subject was a woman in her early sixties who had stroke onset approximately 5 years ago. A single-case ABA design was used. A 2-month baseline period was followed by an 8-week period of weekly gait training and a subsequent 2-month follow-up period. Throughout the study period, she underwent conventional physiotherapy. Outcome measures were the 10-meter walking test, timed up and go test, functional reach test, two-step test, and Berg Balance Scale. [Results] Significant improvements were seen in all outcome measures during the gait training period. Improvements in all outcome measures except walking speed were maintained at follow-up. [Conclusion] Continued gait training with Hybrid Assistive Limb once a week can improve gait and balance performance in patients with chronic stroke, and these improvements are maintained at least for two months.

“…Some of the kinematic differences between participants may be attributed to the effects of walking at a slower speed. Walking at a slower than normal speed has been shown to result in a decrease in peak knee flexion (Kirtley, 2006, Kwon et al, 2014, and is a common characteristic of gait for older adults or stroke survivors who fear they may be at risk for falling (Park andYoo, 2014, Maki, 1997). In this study, participants walked at a selfselected speed, and non-trippers walked faster than trippers (P < .001).…”

Trips are a major cause of falls. Sagittal-plane kinematics affect clearance between the foot and obstacles, however, it is unclear which kinematic measures during obstacle-free walking are associated with avoiding a trip when encountering an obstacle. The purpose of this study was to determine kinematic factors during obstaclefree walking that are related to obstacle avoidance ability. It was expected that successful obstacle avoidance would be associated with greater peak flexion/dorsiflexion and range of motion (ROM), and differences in timing of peak flexion/dorsiflexion during swing of obstacle-free walking for the hip, knee and ankle. Threedimensional kinematics were recorded as 35 participants (young adults age 18-45 (N = 10), older adults age 65+ without a history of falls (N = 10), older adults age 65+ who had fallen in the last six months (N = 10), and individuals who had experienced a stroke more than six months earlier (N = 5)) walked on a treadmill, under obstacle-free walking conditions with kinematic features calculated for each stride. A separate obstacle avoidance task identified trippers (multiple obstacle contact) and non-trippers. Linear discriminant analysis with sequential feature selection classified trippers and non-trippers based on kinematics during obstacle-free walking. Differences in classification performance and selected features (knee ROM and timing of peak knee flexion during swing) were evaluated between trippers and non-trippers. Non-trippers had greater knee ROM (P = .001). There was no significant difference in classification performance (P = .193). Individuals with reduced knee ROM during obstacle-free walking may have greater difficulty avoiding obstacles.
