Importance of Walking Speed


Recently walking speed has been termed the “Sixth Vital Sign” as it appears to be a strong indicator of health status, a predictor of future events, and is used to help determine outcomes such as; functional status, discharge location and the need for rehabilitation. 

A longitudinal study of 11 years found that people with a slower walking speed in middle age were one and a half times more likely to develop dementia compared to people with faster walking speed.  Other research supports walking speed as a predictor of the post hospital discharge location 78% percent of the time.

In 2009 walking speed was chosen by a panel of experts as the standardized assessment to measure locomotion for the Motor Function Domain category of the NIH Toolbox. The reason for this included the following: walking speed is safe, requires no special equipment, can be administered in less than 2 minutes, is easy to calculate, is highly reliable and has published norms.

While walking speed varies by age, gender and anthropometrics, the range for normal walking speed is 1.2-1.4 meters/second (m/s) or 2.64-3.08 mph.. Small changes in walking speed can greatly affect the functional status patients. In a 2006 study using a diverse group of older participants with varying diagnosis, only 0.05 m/s (0.11 mph) was calculated as the needed change for a meaningful improvement in walking speed. For patients without normal walking speed an improvement of at least 0.1 m/s or 0.2 mph has been shown to be a predictor of future well-being, while a decrease in the same amount is linked with poorer health status, more disability, longer hospital stays, and increased medial costs.

Walking is a complex functional activity with many variables that contribute to and influence walking speed. Research has demonstrated that very small improvements in walking speed are linked to function, independence and health status. Understanding, evaluating and treating the variables that affect your patient’s walking speed can mean the difference between independence and morbidity.

The Restoring Efficient Balance and Gait through Targeted Evaluation and Treatment Strategies is unique as it provides the PT with numerous functional approaches to determine exactly where a gait deficit occurs, why it is happening and whether the dysfunction a structural or neuromuscular dysfunction.  From this information appropriate treatment strategies that are quick and effective can be immediately incorporated into any practice settings with lasting results.

What makes Signature Allied Strategies class different than other Gait classes is the focus on the foot and ankle. The foot provides the primary generator of propulsive force in walking and its efficient function is vital to gait and improvements in walking speed. Additionally the foot is the base of support in walking and deficits in its function can lead to falling, neuropathy, slower walking speed, and painful conditions such as bunions and hammertoes.
