Why High-Intensity Gait Training Matters After Stroke

Approximately two-thirds of stroke survivors experience some level of gait impairment—that is, difficulty walking. For rehab professionals, improving walking post-stroke isn’t just important—it’s essential.

For years, physical therapy focused heavily on the mechanics of walking: making each step look “normal.” But this often led to frustration for both patients and therapists. Sessions became slow, repetitive, and low in volume—meaning fewer steps, less intensity, and ultimately, limited progress in gait quality.

Enter high-intensity gait training.

This approach shifts the focus from aesthetics to function and intensity. It’s about getting in significantly more steps—and doing so at a cardiovascular intensity that challenges the brain and body. Research continues to build around its effectiveness, and here’s how it works:

What Counts as “High-Intensity”?

We start by calculating a patient’s age-predicted maximal heart rate. From there, we set a training target—typically 70–85% of that max.

For example:
If your age-predicted max heart rate is 188 bpm, your high-intensity training zone would be:

• Minimum: 141 bpm (75%)
• Maximum: 160 bpm (85%)

Casual walking won’t get you there. So your physical therapist might:

• Increase treadmill speed
• Add resistance or incline
• Use weighted vests or dynamic cues
  All to help you reach that heart rate threshold and drive neuroplastic change.

Specificity Is Key

Intensity alone isn’t enough. We also need specificity—targeting the exact gait deficits you’re experiencing.

Maybe you struggle with:

• Stance Control (standing on one leg while walking)
• Swing phase (advancing your leg forward)
• Propulsion (your walking speed)
• Postural Stability (your balance while walking)

Your therapist will design interventions that challenge those specific components—because generic walking won’t rewire the brain where you need it most.

Your Role in the Process

You don’t have to choose the interventions—that’s your therapist’s job. But your input matters. You can:

• Share your goals
• Report how you’re tolerating sessions
• Ask what you can practice at home
• Make sure you’re fueling your body before sessions with enough hydration and nutrition to support high-intensity work

Recovery is a partnership. And when intensity meets specificity—and your body is ready to work—real progress happens.
