Table 1: Mobility & Functional Assessment Tools Tool Berg Balance Scale

Administration

Description

Strengths

Limitations

Access / Sources

Physiotherapist

14-item scale designed to assess balance and risk of falling of older people in the community

Easy measure administered in 15-20 minutes

Not practical in acute (needs equipment)

Access tool here:

Good community predictor of falls

20 minutes to administer, not practical in acute

#

Found to have high sensitivity for predicting falls Ability to identify risk for falling and used to identify change in risk following rehabilitation High inter-rater and intra-rater reliability Age-related normative values established Tested across community, acute, post-acute, residential care settings

de Morton Mobility Index (DEMMI) #

Physiotherapist

15 hierarchical mobility challenges

Simple, quick and easy to score and administer by clinician observation No special/expensive equipment required Can be administered at the patient’s bedside or in a community setting. Developed based on the Rasch model and therefore provides

Limited to balance Limited to specific patients, not generic

Does not include measure of gait Despite high intra-class correlation coefficient, absolute reliability showed change of 8 points is required to show change in function among older people who are dependent in activities of daily living (ADLs) New tool (published in August 2008) – limited interdisciplinary awareness A one-dimensional measure of ‘mobility’ so other tools required to measure other domains.

Overcomes limitations of existing instruments such as ceiling and floor effects Extensive clinimetric evaluation – Rasch, reliability, validity, responsiveness to change and minimally clinically important difference (MCID)

Modified Elderly Mobility Scale (MEMS)

Timed Up & Go Test #

Physiotherapy; Once mobility level established, if at safe level can be administered by

7 item test of motor function of elderly patients with a spread of functional levels

Assessment of dynamic balance and mobility skills for older people

Quick and easy to administer Valid and reliable Experience of physiotherapist scoring patient does not greatly impact reliability of scoring Concurrent validity when compared to FIM (Functional Independence Measure)

Functional Reach component only practical in clinical setting Needs controlled environment and stairs No self-care component

Rural/regional areas may find difficult as do not have allied health staff seven days

Quick and easy to administer in less than 3 mins

Need a chair at the right height

Can be used across different settings

Difficult for patients with dementia, Parkinsons, visual impairments

Reliability and validity with

Needs to be administered soon after admission

High inter-rater and test-retest reliability for each item and total score, regardless of experience of rater

Suits bedside

Access tool here:

Still reliable but less so for patients of a low functional level, but this may be due to video scoring method during trial

Only provides information on

a trained nurse or allied health assistant

community dwelling older adults

a few aspects of balance

Normative values established in Steffen et al. (2002) and Hill et al. (1999)

Scores do not have depth of information to discriminate between the various sources of impairment

High inter and intra-rater reliability and sensitivity and specificity

Tinetti Assessment Tool: Balance

Physiotherapist

Test measuring gait and balance

#

Unable to administer if person unable to transfer/mobilise without assistance

Simple and easily administered in 10-15 minutes

Not often used in clinical setting

Shorter than some other balance tests

No gait or self care components

Good inter-rater reliability

Requires therapist interpretation

Access tool here: http://www.bhps.org. uk/falls/documents/Ti nettiBalanceAssessme nt.pdf

Not sensitive enough to pick up some function changes Lengthy Validity not reported

Barthel Index #

Requires team of Physiotherapy, Occupational Therapist & Nursing

15 ADL items; Assesses selfcare and mobility activities of daily living

Widely used in geriatric settings Administered in 5-10 minutes Easy and quick to learn Multidisciplinary Good snap shot of inpatient function and covers personal care, mobility and self-care Reliability, validity and overall utility are rated as good to excellent Compares favourably with other ADL

Community rehabilitation / sub-acute setting focused Does not take cognition into account May give broad brush picture, as its ability to reflect change in function limited by a floor effect and lack of sensitivity to change

scales

Functional Independen ce Measure (FIM) and Functional Assessment Measure (FAM)

Requires trained clinician to administer; Team approach

#

Performance Orientated Mobility Assessment #

Physiotherapist

18 items Measures functional status of people in rehabilitation

Widely used in general rehabilitation settings

May not be translatable to acute

Administration by an trained assessor of any discipline

5 hour training required for administration with annual refresher training (costly)

Includes cognition, language, continence

Cost required for use/accreditation

Can be used as a benchmark

18 item mobility assessment, usually in the evaluation of fall risk or falls.

Quantitative assessment of balance and gait

Some items appear subjective

Can be performed at the bedside in about 5 minutes

Not well known

More reliable in detecting functional change in inpatient setting

http://www.birf.info/h ome/bitools/tests/fam.html

Users need to be certified

Reflects what person usually does rather than what he/she can do

Acceptable reliability for assessing ADLs for adults across a wide variety of settings, raters and patients

Access tool here:

Limited focus on physical health (skin integrity, nutrition, medical conditions, pain etc)

Mobility Assessment only, no functional assessment components Lengthy
