OBJECTIVE To determine the minimum detectable change at 95% confidence for the Berg Balance Scale in a group of elderly people, undergoing physiotherapy rehabilitation. DESIGN Multi-centre, test-retest design. SUBJECTS Cross-sectional sample of convenience of people over 65 years (n = 118) without a previous history of stroke, Parkinson's disease or recent hip arthroplasty. RATERS: Physiotherapists working with elderly people, drawn from the Physiotherapy Research into Older People group… 

Figures and Tables from this paper

Minimal clinically important difference of the Berg Balance Scale score in older adults with hip fractures.
TLDR
The effectiveness of meaningful rehabilitation is possible to determine by clarifying the minimal clinically important difference in balance function, which is important for the acquisition of gait, by calculating the MCID of the Berg Balance Scale in older adults with hip fractures.
Sensitivity to Change and Responsiveness of Four Balance Measures for Community-Dwelling Older Adults
TLDR
Important limitations, including ceiling effects and relatively low sensitivity to change and responsiveness, were noted across all balance measures, highlighting their limited utility across the full spectrum of the community-dwelling elderly population.
A comparison of the ceiling effect between Berg Balance Scale and Mini-BESTest in a group of balance trained community-dwelling older adults
TLDR
The MBT presents a significantly smaller ceiling effect and is therefore more suitable for assessing balance even for balance trained older adults and may be used as a short screening tool.
Impairments in balance discriminate fallers from non-fallers in COPD.
Measurement properties of the Motor Evaluation Scale for Upper Extremity in Stroke patients (MESUPES)
TLDR
The Motor Evaluation Scale for Upper Extremity in Stroke patients (MESUPES) has high absolute and relative reliability and is suggested to be a useful tool to evaluate quality of movement in the upper extremity of stroke patients.
Applying the Minimal Detectable Change of a Static and Dynamic Balance Test Using a Portable Stabilometric Platform to Individually Assess Patients with Balance Disorders
TLDR
It is concluded that certain variables were sufficiently sensitive to detect changes linked to balance progression, intended to improve decision making and individualized patient monitoring.
Minimal detectable change for mobility and patient-reported tools in people with osteoarthritis awaiting arthroplasty
TLDR
The 6MWT demonstrates the smallest measurement error amongst a range of tools commonly used to assess disease severity, thus, has the capacity to detect the smallest real change above measurement error in everyday clinical practice.
Effect on Gait Speed, Balance, Motor Symptom Rating, and Quality of Life in Those with Stage I Parkinson's Disease Utilizing LSVT BIG®
TLDR
Assessment of functional improvement at a level of minimal clinically important difference (MCID) in one of four outcome measures: Gait Speed, Berg Balance Assessment, Functional Gait Assessment, and Unified Parkinson's Disease Rating Scale Motor Section indicated improvement based on criteria.
Efficacy of Education with Balance Exercise Program in improving balance and reducing the fear of falls in elderly: A Randomized Clinical trial. -
TLDR
To determine the efficacy of education with Balance Exercise in improving balance and reducing the fear of falls in elderly, there was statistically more significant improvement in Experimental group than Conventional group.

Measuring balance in the elderly: preliminary development of an instrument
TLDR
The goal for this study was to develop a measure of balance appropriate for elderly individuals and there was a high degree of internal consistency, a Cronbach's alpha of .96, which indicates the movements reflect a single underlying dimension.

TLDR
The Dynamic Gait Index appears to be a more sensitive assessment tool in identifying people with vestibular disorders who are at increased risk for falling, based on currently published criteria.
Analysis and Comparison of the Psychometric Properties of Three Balance Measures for Stroke Patients
TLDR
The Postural Assessment Scale for Stroke Patients showed slightly better psychometric characteristics than the other 2 measures, and showed very acceptable levels of reliability, validity, and responsiveness for both clinicians and researchers.
Clinical and laboratory measures of postural balance in an elderly population.
TLDR
The Balance Scale was the most efficient measure to statistically discriminate between subjects according to their use of each type of mobility aide (walker, cane, no aids) and supports the validity of the Balance Scale in this geriatric population.
Defining the minimum level of detectable change for the Roland-Morris questionnaire.
TLDR
The magnitude of CSEMs is sufficiently small to detect change in patients with initial scores in the central portion of the scale (4-20 RMQ points); however, the magnitude is too large to detect improvement in Patients with scores of less than 4 and deterioration in patients who have scores greater than 20.
Berg Balance Scale: Intrarater Test-Retest Reliability Among Older People Dependent in Activities of Daily Living and Living in Residential Care Facilities
TLDR
Investigation of the absolute and relative intrarater test-retest reliability of data obtained with the Berg Balance Scale found that a change of 8 BBS points is required to reveal a genuine change in function among older people who are dependent in activities of daily living and living in residential care facilities.
Testing functional performance in people with Parkinson disease.
TLDR
Because the BBS scores correlate both with UPDRS scores and with scores of all other tests of functional performance, the B BS appears to be a good overall measure of function in this population of people with PD.
The Balance Scale: reliability assessment with elderly residents and patients with an acute stroke.
TLDR
The results support the use of the Balance Scale in these groups and show strong internal consistency within the same rater at two points in time.
