Assessment & Research

Comparison of forward and backward gait in males with and without intellectual disabilities.

Gimunová et al. (2021) · Journal of intellectual disability research : JIDR 2021
★ The Verdict

Backward walking speed drops below the elderly fall-risk line in adults with moderate ID or Down syndrome.

✓ Read this if BCBAs working with adults who have moderate ID or Down syndrome in day programs or group homes.
✗ Skip if Clinicians serving only typically developing clients or very young children.

01Research in Context

01

What this study did

Higgins et al. (2021) watched men walk forward and backward on a lab treadmill.

Some men had intellectual disability or Down syndrome. Others were neurotypical.

The team timed how fast each man walked in both directions.

02

What they found

Backward walking slowed twice as much in men with moderate ID or Down syndrome.

Their speed dropped below 2.16 km/h, a fall-risk line usually seen in frail elders.

Men with mild ID stayed above that line.

03

How this fits with other research

Fleury et al. (2019) tracked real-world falls in 46 % of adults with ID over six months. M et al. give a lab reason: slow backward gait flags the same high-risk group.

Boxum et al. (2018) saw wobblier balance in youth with ASD and lower IQ. Both papers link lower IQ to poorer motor control, just in different tasks.

Brugnaro et al. (2025) found that active kids with Down syndrome move better. Their data in children echo M et al.’s adult finding: Down syndrome plus low activity equals weak mobility.

04

Why it matters

If you serve adults with moderate ID or Down syndrome, test backward gait speed. A simple hallway walk-back can spot fall risk in under a minute. Add balance drills or strength games to their plan.

03Original abstract

BACKGROUND: Intellectual disabilities (ID) affect both cognitive and motor functions. The backward gait is a daily activity and its assessment is used for fall risk estimation and training in the general population. For proper use of backward gait as a rehabilitation tool and in fall prevention programmes for people with ID, it is necessary to determine the backward gait characteristics in the ID population. The aim of this study was to compare the differences between forward and backward gait in persons with nonsyndromic mild and moderate ID, persons with Down syndrome (DS) and a control group of healthy adults. METHODS: Fifty males divided into four groups (mild ID: n = 15, moderate ID: n = 19, DS: n = 6, controls: n = 10) participated in this study. All participants were asked to walk both forward and backward, barefooted and at their natural velocity on a Zebris FDM platform. The Kruskal-Wallis H test was used to compare differences between the analysed groups in forward and backward gait. The Mann-Whitney U test was used to compare the differences between forward and backward gait within each group. RESULTS: The velocity was significantly slower in moderate ID and DS compared to controls in forward and backward gait. When comparing forward and backward gait within each group, the gait velocity decreased in backward gait compared with forward gait by 21.80% in controls, by 33.89% in mild ID, by 34.45% in moderate ID, and by 40.32% in DS. In both moderate ID and DS, the mean backward velocity was slower than 2.16 km/h, the velocity used to identify elderly fallers in the general population. CONCLUSIONS: Gait velocity was especially affected in DS and moderate ID compared with controls. In both mentioned groups, the backward gait velocity suggests an increased risk of falling. Future studies are necessary to examine the possibility of improving balance control and leg muscle strength by backward walking training in the ID population.
