Introduction: Since it is well documented that spatiotemporal gait parameters are affected by body size, it is of limited clinical value to compare individual scores against reference values without taking body size into consideration. For older adults, reference values have been presented in recent reports, but unfortunately the effect of body si...
Article
Background: Symmetry during stair descent can potentially be used as an early functional measure after anterior cruciate ligament reconstruction (ACLR). We have developed a novel application of a single accelerometer-based inertial motion unit (IMU) to identify foot strikes and calculate step times in an ordinary stairway. Purpose: To examine withi...
Article
Background: Stride-to-stride fluctuations, or gait variability, can be captured easily using body worn inertial sensors. Previously, sensor-measured gait variability has been found to be associated with fall risk and central nervous changes. However, further research is needed to clarify the clinical relevance of this method. Objectives: In this...

Introduction: The ability to perform tasks automatically is important for everyday life since it allows for attention to be consciously directed elsewhere. This may be investigated with the dual-task (DT) paradigm by comparing the concurrent performance of two different tasks in relation to the performance of each task separately (i.e. single-task,...
Conference Paper
Background: The ventilatory limitation in patients with COPD is related to expiratory flow limitation (EFL) and static and dynamic lung hyperinflation (DH). Respiratory timing (duty cycle) is the ratio of inspiratory time (Ti) to total time of a breath (Ttot). A shorter duty cycle could compensate for EFL and DH by giving more time for expiration....
Article
The Berg Balance Scale (BBS) has previously shown good measurement properties. However, its ability to detect important change in patients early after stroke is still unknown. The purpose of the present study was to determine the minimal important change (MIC) and its relation to the minimal detectable change (MDC) for BBS in patients early after s...

Background: Restoration of gait is an important goal of rehabilitation after hip fracture. Numerous spatial and temporal gait variables have been reported in the literature, but beyond gait speed, there is little agreement on which gait variables should be reported and which are redundant in describing gait recovery following hip fracture. The aim...
Article
Differences in gait performance can be explained by variations in walking speed, which is a major analytical problem. Some investigators have standardised speed during testing, but this can result in an unnatural control of gait characteristics. Other investigators have developed test procedures where participants walking at their self-selected slo...

Rehabilitating walking in ambulatory patients post-stroke, with training that is safe, task-specific, intensive, and of sufficient duration, can be challenging. Some challenges can be met by using body-weight-supported treadmill training (BWSTT). However, it is not known to what degree walking characteristics are similar during BWSTT and overground...
Article
Full-text available
Rationale: As a result of demographic changes with a presumed rapidly increasing number of older people during the coming decades, a strong increase in the incidence and prevalence of stroke should be expected. Early supported discharge implies that the patients are discharged to their homes as soon as feasible and that rehabilitative treatment is...
Article
Full-text available
Unsupported standing is one of the most important functional tasks involving balance control. Unlike younger people, who have been shown to counteract imbalance preferably with an ankle strategy, older people tend to do so with a hip strategy. These strategies can be described by matching balance measures at floor and hip level, a good match repres...
