Normative Values of the Berg Balance Scale and Timed Up and Go Test

Falls are a significant public health concern for older adults; early identification of people at high risk for falling facilitates the provision of rehabilitation treatment to reduce future fall risk. Berg balance scale is a reliable, valid and widely used tool to measure balance. Normal values of BBS declines with increasing age above 70 at a rate of 0.75 points per year. Timed up and go test Assess mobility, balance, falls risk. Normative data on both these test for our population is not established. Therefore this study aimed at finding normal scores of both these in our community-dwelling elderly females. For this purpose, data will be calculated from community-dwelling elderly females. BBS and TUG would be performed on each subject meeting our inclusion criteria after their consent. Data will be recorded and analyzed using Statistical Package for the Social Sciences (SPSS) version 23. We will find the mean and standard deviation. Thus this study will provide normal reference values of BBS and TUG in our community

Balance deficits in elderly adults can arise from the process of ageing, such as age-related changes associated with the sensory system (vestibular, visual, somatosensory) or diseases such as cerebrovascular accident, arthritis, peripheral neuropathies, or disuse due to immobility. Balance is maintained when all the forces acting on the body are balanced so that one's centre of gravity is controlled within the base of support in static postures, during movement, and when responding to external disturbances. Normative data are important when interpreting any balance tool. the knowledge that a person or group of people Have worse balance than a healthy person of the same age may assist the identification and effective management of balance problem.

The BBS is a performance-based measure consisting of 14 items and a maximum score of 56. Originally developed to assess balance in older adults, it was subsequently adopted as a falls-risk prediction tool for older adults (although studies have differed in the recommended cut off score for falls risk. The BBS consists of 14 functional tasks of increasing difficulty, each scored from 0 to 4 (0¼unable to perform the task; 4¼task performed independently). The maximum score of 56 indicates no identifiable balance difficulties.

The 'timed up and go' test (TUG) is a simple, quick and widely used clinical performance-based measure of lower extremity function, mobility and fall risk. The TUG has been studied in elderly populations Women) the test procedure for the TUG is relatively simple. Subjects are asked to stand up from a standard chair (seat height between 44 and 47 cm), walk a distance of 3 m (marked on the floor) at a comfortable pace, turn, walk back and sit down. Subjects are permitted to use routine walking aids and are instructed not to use their arms to stand up. No physical assistance is given. The time to complete the task is measured with a stopwatch. Timing commences on the command 'go' and stops when the subject's back is positioned against the back of the chair after sitting down.

Use of local normative data of the specific population is recommended for more meaningful interpretation of TUG result Therefore, the aim of this study was to identify the normative data of TUG test and berg balance scale among community-dwelling older adults.the research was conducted in 2014 on normative scores on berg balance scale declines after age 70 in healthy community-dwelling people. it was a systematic review. purpose of this study was to find What is the mean Berg Balance Scale score of healthy elderly people living in the community and how does it vary with age? Group of healthy community-dwelling people with a mean age of 70 years or greater that has undergone assessment using the Berg Balance Scale were included. Mean and standard deviations of Berg Balance Scale scores within cohorts of elderly people of known mean age were measured. The mean Berg Balance Scale scores ranged from 37 to 55 out of a possible maximum score of 56. Although participants aged around 70 years had very close to normal Berg Balance Scale scores, there was a significant decline in balance with age at a rate of 0.7 points on the 56-point Berg Balance Scale per year. It was concluded that Healthy community-dwelling elderly people have modest balance deficits, as measured by the Berg Balance Scale, although balance scores deteriorate and become more variable with age.

the study was conducted on 'Timed Up and Go' test: Age, gender and cognitive impairment stratified normative values of older adults' in 2017. The aim of this study was to establish 'Timed up and Go' test (TUG) normative data among community-dwelling older adults stratified based on cognitive status, gender and age groups. A total of 2084 community-dwelling older adults from wave I and II were recruited through a multistage random sampling method. TUG was performed using the standard protocol and scores were then stratified based on with and without mild cognitive impairment (MCI), gender and in 5-year age groups ranging from ages of the '60s to '80s. 529(16%) participants were identified to have MCI. descriptive analysis showed, participants with MCI, women and older in age took a longer time to complete TUG, as compared to men with MCI across all age groups with exceptions for some age groups. These results suggested that MCI needs to be taken into consideration when testing older adults using TUG, besides age and gender factors.

a study on "Berg balance scale" and "timed up and go" Discriminates between fallers and non-fallers, in people with Multiple S. Different cut-offs have been used for BBS. With a cut-off at \>44; high specificity (90%) but low sensitivity (40%) were found. Using ≤55 as cut-off yielded high sensitivity (94%) but low specificity (32%).TUG has not shown discriminant ability. The aim was to examine discriminant validity for BBS and TUG; fallers vs. non-fallers and predictive properties using previously suggested cut-offs. Data from three samples of PwMS (n=220) with imbalance was used. Testing was conducted by experienced research physiotherapists. Participants were classified as fallers or non-fallers. Mann-Whitney U test and ROC were used. BBS median for fallers was 45 points (n:108) and for non-fallers 50 points (n:99). TUG median was 17.5 seconds (n=108) for fallers and 13.2 seconds (n=99) for non-fallers.BBs: Using \>44 points as cut-off correctly identified 51% of the fallers and 37% of the non-fallers. Using ≤55 correctly identified 96% fallers and 15% non-fallers.TUG: A cut-off (19.34 seconds) was chosen by maximizing the sum of sensitivity and specificity resulting in sensitivity at 70% and specificity at 43%.

Susan W Muir et al. conducted a study in 2008 on Use of the Berg Balance Scale for Predicting Multiple Falls in Community-Dwelling Elderly People. it was A Prospective Study. The objective of this study was to examine the predictive validity of the Berg Balance Scale (BBS) for 3 types of outcomes-any fall (1 fall), multiple falls (2 falls), and injurious falls-by use of sensitivity, specificity, receiver operating characteristic (ROC) curves, area under the curve, and likelihood ratios. A sample of 210 community-dwelling older adults received a comprehensive geriatric assessment at baseline, which included the BBS to measure balance. Data on prospective falls were collected monthly for a year. They concluded that the use of the BBS as a dichotomous scale to identify people at high risk for falling should be discouraged because it fails to identify the majority of such people. The predictive validity of this scale for multiple falls is superior to that for other types of falls.
