Abstract
Frequently, clinical balance outcome measures are limited by floor or ceiling effects and provide insufficient resolution to determine subtle deficits. Detailed assessment of postural control obtained through posturography may be cost-prohibitive or logistically infeasible in some clinical settings. Two-dimensional (2D) motion analysis may provide a clinically feasible means of obtaining detailed quantification of balance deficits. Forty-five participants aged 18-80 years, with and without Parkinson disease, performed the Push and Release (PR) test, sit-to-stand (STS), and timed single leg stance (SLS). Performance was captured simultaneously using a three-dimensional (3D) (10-camera laboratory-based 3D motion capture system and 3D motion analysis software) and 2D (two commercially available video cameras and 2D motion analysis software) system. Agreement was excellent between 2D and 3D systems for all outcomes of the PR and SLS (intraclass correlation coefficients [ICC2,1 ] 0.96-0.99, 95% CIs 0.92-0.98 to 0.99-1.0), and ranged from fair to excellent for STS outcomes (ICC2,1 0.59-0.93, 95% CIs 0.36-0.75 to 0.87-0.96). Test-retest reliability (ICC3,1 0.89-1.0, 95% CIs 0.76-0.96 to 1.0-1.0) and inter-rater reliability (ICC2,1 0.77-1.0, 95% CIs 0.61-0.87 to 1.0-1.0) of the 2D obtained outcomes were excellent. A technology package of commonly available video cameras and 2D motion analysis software was a valid and reliable method for quantifying outcomes of postural control tasks in people with a range of balance abilities. Two-dimensional analysis can be used in clinical practice to provide balance assessments as a cost-effective alternative to 3D motion capture.

This perspective article will discuss the potential role of body-worn movement monitors for balance and gait assessment and treatment in rehabilitation. Recent advances in inexpensive, wireless sensor technology and smart devices are resulting in an explosion of miniature, portable sensors that can quickly and accurately quantify body motion. Practical and useful movement monitoring systems are now becoming available. It is critical that therapists understand the potential advantages and limitat...

Decreased reactive postural responses in elderly adults may place them at increased risk for falls and related injuries. The first step in addressing the high rate of falls in the elderly population is to determine a baseline for postural response in healthy young and healthy elderly individuals. To determine these age-related differences in reactive postural responses during recovery from posterior and anterior perturbations, we used the tether-release method in conjunction with a motion analys...

Background The Balance Evaluation Systems Test (BESTest) is a new clinical balance assessment tool, but it has never been validated in patients with subacute stroke. Objective The purpose of this study was to examine the reliability and validity of the BESTest in patients with subacute stroke. Design This was an observational reliability and validity study. Methods Twelve patients participated in the interrater and intrarater reliability study. Convergent validity was investigated in 70 patients...

Background Patients with Parkinson's disease (PD) suffer from a high fall risk. Previous approaches for evaluating fall risk are based on self-report or testing at a given time point and may, therefore, be insufficient to optimally capture fall risk. We tested, for the first time, whether metrics derived from 3 day continuous recordings are associated with fall risk in PD. Methods and Materials 107 patients (Hoehn & Yahr Stage: 2.6±0.7) wore a small, body-fixed sensor (3D accelerometer) on lower...

In order to investigate the effects of speed and slope on kinematic parameters, we studied the step parameters of 12 elite race walkers on a treadmill at different speeds (3.61, 3.89, and 4.17 m·s-1) and slopes (0, 2, and 7%). A high-speed digital camera (210 Hz) was used to record motion, and 2D data were analyzed with Dartfish 5.5Pro. The parameters studied were step length (SL), step frequency (SF), and contact time (CT). The results showed that the increases in SL were linearly related to in...

The aim of this study was to verify the influence of the combination of different running speeds and slopes based on main kinematic parameters in both groups of elite (RE) and amateur (RA) marathon runners. All subjects performed various tests on a treadmill at 0, 2, and 7% slopes at different speeds: 3.89, 4.17, 4.44, 4.72, and 5.00 m·s-1. A high speed digital camera, 210 Hz, has been used to record; Dartfish 5.5Pro has been used to perform a 2D video analysis. Step length (SL), step frequency ...

Abstract While balance and gait limitations are hallmarks of multiple sclerosis (MS), standard stopwatch-timed measures practical for use in the clinic are insensitive in minimally affected patients. This prevents early detection and intervention for mobility problems. The study sought to determine if body-worn sensors could detect differences in balance and gait between people with MS with normal walking speeds and healthy controls. Thirty-one MS and twenty-eight age- and sex-matched control su...

Many research designs require the assessment of inter-rater reliability (IRR) to demonstrate consistency among observational ratings provided by multiple coders. However, many studies use incorrect statistical procedures, fail to fully report the information necessary to interpret their results, or do not address how IRR affects the power of their subsequent analyses for hypothesis testing. This paper provides an overview of methodological issues related to the assessment of IRR with a focus on ...

Objective. The purpose of this study was to explore the usefulness of the Mini-BESTest compared to the Berg Balance Scale in evaluating balance in people with PD of varying severity. We evaluated (1) the distribution of patients scores to look for ceiling effects, (2) concurrent validity with severity of disease, and (3) the sensitivity/specificity of separating people with or without postural response deficits. Subjects. Ninety-seven people with PD were tested for balance deficits using the Ber...

Background Walking for people with Parkinson’s disease (PD) degrades during motor-cognitive interplay (i.e., dual task conditions). Declining gait mechanics and turning ability result in more frequent falls and an interruption of daily activities in persons with PD.

Motor imagery (MI) is increasingly used in neurorehabilitation to facilitate motor performance. Our previous study results demonstrated significantly improved walking after rhythmic-cued MI in people with multiple sclerosis (pwMS). The present feasibility study was aimed to obtain preliminary information of changes in walking, fatigue, quality of life (QoL) and MI ability following cued and non-cued MI in pwMS. The study further investigated the feasibility of a larger study and examined the rel...
