The Elderly Mobility Scale (EMS) is a 7-item performance test that scores mobility in older adults from 0 to 20. It covers bed mobility, sit-to-stand, standing, gait, a timed 6-metre walk and functional reach. Below 10 means dependent in mobility and daily activities, 10 to 13 is borderline, and 14 or more suggests independence. It was published by R. Smith in Physiotherapy in 1994 and was designed for older people in hospital, especially those who are frail.
Use the calculator above to score the seven items you observed. This guide gives the exact item wording and points, the cutoffs and where sources disagree on them, reliability and validity data, how to run the test, and how to document it. Every figure is tied to a source at the end of the page.
Elderly Mobility Scale at a glance

EMS scoring: all 7 items and their points
The table follows the Chartered Society of Physiotherapy (CSP) scoring form. Score what the person actually does during testing, not what they report.
| Item | Scoring options | Points |
|---|---|---|
| 1. Lying to sitting | Independent / needs help of 1 person / needs help of 2 or more people | 2 / 1 / 0 |
| 2. Sitting to lying | Independent / needs help of 1 person / needs help of 2 or more people | 2 / 1 / 0 |
| 3. Sitting to standing | Independent in under 3 seconds / independent but over 3 seconds / needs help of 1 person (verbal or physical) / needs help of 2 or more people | 3 / 2 / 1 / 0 |
| 4. Standing | Stands without support and can reach forward / without support but needs support to reach / stands but needs support / stands only with the physical support of another person | 3 / 2 / 1 / 0 |
| 5. Gait | Independent, with or without a stick / independent with a frame / mobile with an aid but turning is erratic or unsafe / needs physical help or supervision | 3 / 2 / 1 / 0 |
| 6. Timed walk (6 m) | Under 15 seconds / 16 to 30 seconds / over 30 seconds / unable to cover 6 metres | 3 / 2 / 1 / 0 |
| 7. Functional reach | Over 20 cm / 10 to 20 cm / under 10 cm | 4 / 2 / 0 |
Two details to watch. The CSP form leaves exactly 15 seconds unassigned in the timed walk, so decide a local rule and document it. An NHS hip fracture audit form prints the reach distances as over 16 cm, 8 to 16 cm and under 8 cm, so the thresholds on some local forms differ from the CSP form. Use the version your service has approved and record which one you used.
EMS calculator: how the total is calculated
Add the seven item scores. The maximum is 2 + 2 + 3 + 3 + 3 + 3 + 4 = 20. The calculator at the top of this page does this and shows the band. Because the items have different maximums, the functional reach item carries the most weight, and a person who cannot reach 10 cm loses up to 4 of the 20 points.
EMS score interpretation
| Total score | Interpretation | What to do with it |
|---|---|---|
| Below 10 | High dependency in mobility and daily activities | Plan for help with transfers and walking, and look for rehabilitation potential. Reassess as the person changes. |
| 10 to 13 | Borderline. Needs some help with mobility | Look at which items cost points. Targeted work on transfers, standing balance or gait often fits. |
| 14 or more | Independent in mobility and ADL, relatively safe | Check balance and falls risk with a more sensitive test, because the EMS has a ceiling effect. |
The score of 14. Most summaries (Medbridge, Theraplatform, Physiopedia) treat 14 or more as independent. The CSP form prints 10 to 14 as borderline and above 14 as independent. Write the version you used so the next clinician reads the score the same way.
Does the EMS predict falls?
The evidence is mixed. One summary says the EMS did not predict future falls or discharge destination, while another reports that scores below 15 were seen in multiple fallers. Do not use the EMS alone to estimate fall risk. Pair it with a balance measure such as the Berg Balance Scale calculator or the Berg Balance Scale test guide, and with gait and strength tests such as the 10-Meter Walk Test, 6-Minute Walk Test and 30-Second Sit-to-Stand Test.
How to administer the EMS
- Set up. You need a metre rule, a stopwatch, a bed and a chair, and the person's usual walking aid. Mark a 6-metre walkway.
- Test in order. Lying to sitting, sitting to lying, sitting to standing, standing, gait, timed walk, then functional reach. Allow rests, and have a second person nearby if the patient is unsteady.
- Score what you see. Record each item straight after it is done. If help is needed, score the amount of help actually given.
- Time the walk. Time over 6 metres with the usual aid and note the aid used.
- Measure reach. Standing, measure how far the person reaches forward without stepping.
- Add up and record. Total the seven scores, note the version of the form, the aid used and the date, then repeat at set points.
EMS reliability and validity
| Property | Reported finding | Source |
|---|---|---|
| Concurrent validity with the Barthel Index | Spearman's rho 0.962 (n=36, ages 70 to 93) | Physiopedia |
| Concurrent validity with the Functional Independence Measure | Spearman's rho 0.948 | Physiopedia |
| Inter-rater reliability | 0.88 reported; two studies (n=19 and n=15) found no significant rater differences | Medbridge, Physiopedia |
| Intra-rater reliability | No significant differences across 15 physiotherapists | Physiopedia |
| Responsiveness | In 83 older adults (mean age 79), the EMS was significantly more likely to detect improvement than the other measures compared (p below 0.001) | Physiopedia |
| Ceiling effect | Reported in more capable people | Physiopedia |
| Minimal detectable change and MCID | One secondary summary reports an MDC of 4.3 points and an MCID range of 2 to 6.97. Confirm in the primary study before relying on it | Theraplatform |
EMS vs other mobility and balance measures
| Measure | What it captures | How it differs from the EMS |
|---|---|---|
| EMS | Bed mobility, transfers, standing, gait, timed walk and reach in one 20-point score | Broad mobility profile for frail older adults, especially in hospital |
| Berg Balance Scale | 14 balance tasks | Focuses on balance, so it is more sensitive for higher-functioning people |
| Functional Reach Test | Forward reach in standing | One test of dynamic balance. The EMS includes a version as item 7 |
| 10-Meter Walk Test | Walking speed | A single speed measure. The EMS times only 6 metres as one item |
| de Morton Mobility Index (DEMMI) | Mobility on a 100-point interval scale | Reported MDC of 10.5 and MCID of 8.4 points in a geriatric rehabilitation ward (JRM study) |
| Modified EMS (Kuys and Brauer, 2006) | Modified version of the EMS | Adapted to reduce limits of the original. Check its own scoring |
Documenting the EMS and coding
Record the total, each item score, the form version, the walking aid used and the date. Tie the score to function: which transfers or walking tasks limit independence and what the plan changes. Billing rules depend on the payer.
| Code | Description | Note |
|---|---|---|
| R26.2 | Difficulty in walking, not elsewhere classified | SPRY code page for R26.2 |
| R26.81 | Unsteadiness on feet | SPRY code page for R26.81 |
| M62.81 | Muscle weakness (generalized) | SPRY code page for M62.81 |
| R29.6 | Repeated falls | Use when the record supports repeated falls |
| Z91.81 | History of falling | Risk factor code |
| R54 | Age-related physical debility | Use only when documented by the provider |
Confirm each code against the current ICD-10-CM set. For a PT, scoring the EMS is usually part of the evaluation or re-evaluation (CPT 97161 to 97163 and 97164). CPT 97750 (physical performance test or measurement, with a written report, each 15 minutes) is sometimes billed separately, but payer rules vary, so check the policy first. See the ICD-10 code library, the CPT code library and our physical therapy CPT codes reference sheet. To keep scores in the chart and trend them over time, see SPRY documentation and reporting and analytics.
Frequently asked questions
What is the Elderly Mobility Scale?
The Elderly Mobility Scale (EMS) is a 7-item performance test of mobility in older adults, scored 0 to 20. It was published by R. Smith in Physiotherapy in 1994 and was designed for older people in hospital.
How do you score the Elderly Mobility Scale?
Score seven items: lying to sitting (0 to 2), sitting to lying (0 to 2), sitting to standing (0 to 3), standing (0 to 3), gait (0 to 3), timed 6-metre walk (0 to 3) and functional reach (0 to 4). Add them for a total out of 20.
What is a normal EMS score?
A score of 14 or more suggests independence in mobility and daily activities. Scores of 10 to 13 are borderline and scores below 10 suggest dependency.
What does an EMS score below 10 mean?
It suggests high dependency in mobility and daily activities. The person is likely to need help with transfers and walking.
Is a score of 14 independent or borderline?
It depends on the version. Several summaries treat 14 or more as independent. The CSP form prints 10 to 14 as borderline and above 14 as independent. Record which version you used.
Does the EMS predict falls?
The evidence is mixed. One summary says it did not predict future falls or discharge destination, while another reports lower scores in multiple fallers. Use it with a balance test, not alone.
How long does the EMS take?
About 15 minutes according to the CSP, and it needs minimal training and basic equipment: a metre rule, stopwatch, bed, chair and the person's usual walking aid.
What are the limitations of the EMS?
It has a ceiling effect, so capable older adults can score near 20 despite balance problems. Reach cutoffs also differ between local forms, and exactly 15 seconds is not assigned on the CSP timed walk.
Can I use the EMS calculator without clinical training?
The calculator only adds the scores you enter. Scoring the items needs a trained clinician who can observe the person safely, and interpretation belongs in the wider clinical picture.
What is the minimal detectable change for the EMS?
One secondary summary reports 4.3 points, with an MCID range of 2 to 6.97. Check the primary study before using these numbers for clinical or research decisions.
