Does your gait change as you age? Understanding the shifts in your stride

An estimated 15% of people over 60 have a gait disorder, and this number increases with age. This statistic underscores a critical aspect of healthy aging: a noticeable change in your gait is a common but not always harmless development. Understanding whether your gait change is a result of normal aging or a sign of an underlying medical condition is essential for maintaining your mobility and independence.

Quick Summary

Yes, gait does change with age due to a combination of factors, including both normal physiological adaptations and potential underlying medical conditions. These changes often involve a slower pace, shorter steps, and a wider stance, but significant alterations like shuffling or loss of balance can indicate more serious health issues.

Key Points

• Normal vs. Pathological: Normal age-related gait changes include slower speed, shorter steps, and a wider stance, while shuffling, unsteady, or freezing gaits often indicate an underlying medical condition.

• Not Inevitable: Significant gait disorders are not an unavoidable part of aging; many are linked to treatable health issues and can be managed effectively.

• Exercise is Key: Regular physical activity, including strengthening exercises and balance training, is the most effective preventative measure for age-related gait decline.

• Know the Red Flags: Sudden or significant changes, like frequent falls, shuffling, or marked unsteadiness, warrant immediate medical evaluation.

• Safety First: Making simple home modifications, such as removing clutter and adding grab bars, can significantly reduce the risk of falls associated with altered gait.

• Assess and Adapt: A physical therapist can provide a professional gait analysis and recommend appropriate interventions, including corrective footwear or assistive devices.

Normal age-related gait changes

As the body ages, certain subtle and natural physiological changes can influence the way a person walks. These are not considered pathological but rather adaptive strategies to maintain stability as strength and sensation shift.

• Decreased Gait Velocity: Walking speed naturally declines after the age of 70, a change primarily attributed to taking shorter steps rather than fewer steps per minute. This is a natural consequence of age-related muscle loss (sarcopenia) and a decreased ability to generate force.
• Increased Double Stance Time: The time a person spends with both feet on the ground during a walking cycle increases with age. This is an adaptive, cautious strategy to increase stability and reduce the risk of falling.
• Wider Stance: A slight increase in the width of the walking base is common. This widens the base of support, offering better balance, especially on uneven surfaces.
• Postural Adjustments: Changes in posture, such as a slight forward stoop, can occur due to factors like weak abdominal muscles and increased abdominal fat. This is different from the more pronounced stooped posture seen in certain diseases.
• Reduced Joint Motion: There can be minor changes in the range of motion in the pelvis, hips, and ankles. For instance, ankle push-off force tends to decrease, impacting the length and vigor of strides.
• Reduced Arm Swing: While not a definitive marker of aging alone, a reduction in the natural arm swing can occur. This may be part of an overall more cautious walking pattern.

Pathological gait changes to watch for

Not all gait changes are benign. Many significant alterations in gait are not an inevitable part of aging but are linked to underlying medical conditions. These pathological gaits can often serve as early indicators of disease.

Gait changes associated with neurological conditions

• Shuffling Gait: Often associated with Parkinson's disease, this involves taking small, shuffling steps with reduced arm swing and a forward-leaning posture.
• Ataxic Gait: Characterized by uncoordinated, unsteady, and wide-based walking, often due to cerebellar disorders.
• Frontal Gait Disorder (Gait Apraxia): Involves difficulty initiating or continuing to walk, with the feet appearing "magnetized" to the floor. It is linked to frontal lobe dysfunction, which can be seen in dementia or normal-pressure hydrocephalus.

Gait changes linked to musculoskeletal issues

• Antalgic Gait: A limp caused by pain, resulting in a shortened stance phase on the affected side. This is commonly caused by arthritis or injury.
• Trendelenburg Gait (Waddling): A side-to-side lurching motion where the pelvis drops on the side of the swinging leg. This indicates weakness in the hip muscles, often due to conditions like osteoarthritis.

Comparing normal vs. pathological gait changes

To distinguish between normal age-related adaptations and potential health issues, it is helpful to compare the characteristics. The distinction is crucial for proper assessment and intervention.

Feature	Normal Age-Related Change	Pathological Change
Walking Speed	Gradual, subtle decline.	Significant, often rapid, and disproportionate slowing.
Step Length	Shorter steps.	Variable or very short, shuffling steps.
Stance	Slightly wider base for cautious walking.	Can be very wide and unstable (ataxic) or narrow and shuffling (Parkinsonian).
Symmetry	Generally symmetrical motion.	Noticeable asymmetry, such as favoring one leg due to pain.
Initiation	No trouble starting to walk.	Hesitation or freezing upon initiation.
Balance	Minor increase in body sway.	Marked unsteadiness and frequent stumbling or falling.

Strategies for preventing and managing gait changes

An active and preventative approach is key to mitigating negative gait changes and maintaining mobility. Many gait issues can be improved or managed with the right interventions.

Exercise and physical therapy

• Strengthening Exercises: Focus on building lower body strength through activities like squats, leg presses, and heel raises.
• Balance Training: Incorporate activities such as Tai Chi, tandem walking, and single-leg stands to improve coordination and postural control.
• Gait Retraining: A physical therapist can use gait analysis to identify specific mechanical issues and create a personalized plan.

Lifestyle and safety adjustments

• Appropriate Footwear: Wear supportive shoes with non-slip soles. Avoid high heels and slippers that can increase the risk of trips and falls.
• Home Modifications: Remove tripping hazards like rugs and clutter. Install handrails on stairs and grab bars in bathrooms.
• Regular Medical Checkups: This is crucial for early detection of underlying conditions. A doctor can review medications for side effects that affect balance.

Using assistive devices

• For some, devices like canes or walkers can be necessary to enhance stability. A physical therapist can ensure the device is properly fitted and used correctly.

When to see a doctor

While some changes are normal, it's vital to know when to seek professional medical advice. Consult a healthcare provider if you notice any sudden or significant changes in your walking pattern.

• Frequent or unexplained falls.
• Persistent pain when walking.
• Noticeable shuffling, dragging of feet, or difficulty starting to walk.
• Unsteadiness or a constant feeling of being off-balance.
• Any sudden change, which could signal a more serious condition like a stroke.

Conclusion

While a change in gait is common with age, it is not always benign. Distinguishing between normal, slow adaptations and potentially pathological issues is a critical step for maintaining mobility and preventing falls. By remaining active, making home safety adjustments, and seeking medical attention for concerning symptoms, seniors can proactively manage their gait health. Regular exercise, especially focusing on strength and balance, and consulting a healthcare professional are the most effective ways to preserve walking ability and independence for years to come. Remember, preserving a steady stride is a vital part of healthy aging.
