What You Need to Know Before You Apply

What is the purpose of this trial?

This study aims to determine the immediate and short-term effects of treadmill oscillation walking (TOW) exercise on hip and knee neuromechanics and gait characteristics in individuals post-stroke. It was hypothesized that compared to baseline, individuals poststroke (N=15) will show increased hip abductor and knee extensor muscle activity and torque production, and increased limb loading and walking speeds during TOW and following a 6-week TOW intervention, reflecting that TOW can enhance gait function through improved hip and knee neuromechanical activation.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is treadmill oscillation walking safe for humans?

Treadmill training, often with body weight support using a harness, has been used safely in stroke recovery to help patients walk again. The studies suggest it is generally safe for humans, as it is a common method used in rehabilitation. ^{1 2 3 4 5}

How is Treadmill Oscillation Walking different from other stroke recovery treatments?

Treadmill Oscillation Walking is unique because it involves walking on a treadmill with or without body weight support, allowing patients to practice complex walking patterns repetitively, which can lead to more symmetrical walking and less muscle stiffness compared to traditional floor walking. ^{1 2 6 7 8}

What data supports the effectiveness of the treatment Treadmill Oscillation Walking for stroke recovery?

Research shows that treadmill training, often combined with rhythmic auditory stimulation or body weight support, is effective in improving walking ability in stroke patients. It helps patients walk more symmetrically and with better stability, which can lead to improved overall activity levels. ^{1 2 4 7 9}

Are You a Good Fit for This Trial?

This trial is for individuals who had a stroke over 6 months ago, can stand unaided for 5 minutes, walk 10 meters with or without help, and have sufficient cognitive function. They must have more difficulty loading the affected limb during walking. Excluded are those with certain blood pressure or heart rate issues, joint replacements, severe bone/joint problems affecting gait beyond stroke effects, multiple strokes, cerebellar stroke or other major health conditions.

Inclusion Criteria

I have had partial paralysis on one side due to a stroke over 6 months ago.

My affected limb supports over 6% less weight than my unaffected limb when I walk.

I can walk 10 meters by myself or with help.

Exclusion Criteria

A resting blood pressure outside of the range of 90/60 to 170/90 mm Hg

Pregnancy by self-report

I don't have health issues preventing me from exercising, aside from my stroke.

Published Research Related to This Trial

In a study involving 19 chronic stroke patients, those who underwent treadmill walking training with rhythmic auditory stimulation (TRAS) showed significant improvements in various gait parameters compared to those who trained with over ground walking (ORAS).

The TRAS group demonstrated enhanced walking speed, step cycle, step length of the unaffected limb, and overall gait ability, suggesting that treadmill training with rhythmic auditory feedback is an effective rehabilitation method for improving gait in stroke patients.

Comparison between treadmill training with rhythmic auditory stimulation and ground walking with rhythmic auditory stimulation on gait ability in chronic stroke patients: A pilot study. Park, J., Park, SY., Kim, YW., et al.[2018]

Whole-body vibration combined with treadmill training (WBV-TT) significantly improved walking performance in chronic stroke patients, enhancing metrics like walking speed, cadence, and step length over a 6-week intervention involving 30 participants.

WBV-TT was found to be more effective than traditional treadmill training alone, indicating that the addition of vibration therapy can lead to better rehabilitation outcomes for stroke patients.

Treadmill therapy with partial body weight support (BWS) significantly improves gait ability in nonambulatory stroke patients by allowing them to practice complex walking patterns, leading to more symmetrical walking and reduced spasticity.

Clinical studies indicate that treadmill training is as effective as traditional physiotherapy methods for improving gait in both chronic and acute stroke patients, with upcoming multicenter trials expected to further validate its efficacy.

Treadmill training with partial body weight support after stroke. Hesse, S., Werner, C., von Frankenberg, S., et al.[2019]

A systematic review of 11 trials involving 458 participants found no statistically significant differences in walking speed or dependency between treadmill training with or without body weight support and other interventions for stroke rehabilitation.

There was a slight trend suggesting that treadmill training with body weight support may improve walking speed in individuals who can walk independently, but this finding was not strong enough to be conclusive.

A systematic review of 15 trials involving 622 participants found no statistically significant differences in walking speed or dependence between treadmill training with or without body weight support and other interventions for stroke rehabilitation.

While some individual studies suggested potential benefits of treadmill training with body weight support for dependent walkers, the overall evidence is limited, and adverse events were more common in treadmill training groups but not serious.

A randomized controlled trial involving 130 non-ambulatory stroke patients will assess the effectiveness of treadmill walking with partial weight support compared to routine overground walking in helping patients achieve independent walking.

The study aims to determine if the treadmill intervention leads to independent walking more often, earlier, and with better quality, which could enhance long-term health and community participation for stroke survivors.

Supported treadmill training to establish walking in non-ambulatory patients early after stroke. Ada, L., Dean, CM., Morris, ME.[2022]

In a study involving 21 newly ambulatory stroke patients, 10 minutes of treadmill walking led to greater knee extension at heel strike during subsequent overground walking compared to 10 minutes of overground walking, indicating a potential benefit of treadmill practice on walking mechanics.

The effects of treadmill walking were more pronounced in poorer walkers, who showed a greater increase in step length of the non-paretic limb, suggesting that treadmill training may be particularly beneficial for those with more significant walking difficulties.

Treadmill training with or without body weight support does not significantly improve the likelihood of independent walking in stroke patients compared to other physiotherapy interventions, based on a review of 44 trials with 2658 participants.

However, treadmill training does lead to significant improvements in walking speed and endurance, particularly in patients who are already able to walk, with some benefits in endurance lasting beyond the initial training period.

Treadmill training, with or without body weight support, does not significantly improve the likelihood of independent walking in stroke patients compared to other physiotherapy interventions, based on a review of 56 trials with 3105 participants.

However, treadmill training does lead to modest improvements in walking speed and endurance, particularly in stroke patients who are already able to walk, suggesting it may be more beneficial for those with some walking ability rather than those who are completely dependent.
