Treadmill training and physiotherapy similarly improve dual task gait performance: a randomized-controlled trial in Parkinson's disease.
Featured on Physle Daily · Tuesday, 25 August 2026
Walking while thinking, such as talking or counting while moving, is a common daily challenge for people with Parkinson's disease, and it tends to slow gait and raise fall risk more than walking alone. This trial asked whether treadmill training or individualized physiotherapy, given as an intensive two-week program, could improve walking speed during this kind of dual-task condition. Both groups improved their dual-task gait speed, along with several other gait measures, symptom scores, balance scores, and walking capacity, and the improvements were similar between the two approaches. The interesting part is that neither method proved clearly superior to the other.
This suggests both intensive gait-focused therapy formats can support safer, more independent walking in people with mild to moderate Parkinson's disease, but the study did not identify a group receiving no active training, so it cannot confirm how much of the improvement came from the interventions themselves versus other factors like practice or natural fluctuation.
If you or someone you care for has Parkinson's disease, you may have noticed that walking gets harder when you're also doing something else, like talking or counting backward. This kind of split attention while walking, called dual-task walking, is linked to slower steps and a higher chance of falling.
Researchers wanted to know whether two different types of intensive physical therapy over two weeks, one using a treadmill and one using individualized hands-on physiotherapy, could help with this problem. Both groups of patients improved their walking speed while multitasking, along with other measures of balance, movement symptoms, and walking ability. Importantly, one method wasn't shown to work better than the other, meaning patients and clinicians may have flexibility in choosing an approach that fits their preferences or circumstances. The main limitation is that there wasn't a comparison group who received no training at all, so it's not fully certain how much of the improvement came specifically from these therapies rather than other factors.
This is a summary of research, not medical advice. Talk to your own healthcare provider about anything affecting your care.
This randomized controlled trial compared two structured two-week interventions, individualized physiotherapy versus treadmill training, in 105 patients with mild to moderate Parkinson's disease, using dual-task gait speed as the primary outcome measured via sensor-based gait analysis. Both groups received ten individual 25-minute sessions plus group therapy, with treadmill training producing a 4.2% improvement in dual-task gait speed and physiotherapy producing an 8.3% improvement; both changes were statistically significant within groups.
However, no significant interaction effect was found between group and time, meaning the abstract does not establish that physiotherapy outperformed treadmill training or vice versa. Secondary outcomes, including additional gait parameters, motor symptom severity (UPDRS-III), balance (Berg Balance Scale), and walking capacity, improved significantly and similarly across both arms. This pattern of parallel within-group gains without a significant between-group difference suggests both intervention types may be comparably useful for addressing dual-task gait deficits, though the trial lacked a no-treatment or usual-care control arm, limiting causal inference about intervention-specific effects versus natural improvement or practice effects.
Sample size, while reasonable for a physiotherapy trial, still represents a single study, and replication with control comparison would strengthen confidence in these findings.
Both treadmill training and individualized physiotherapy produced statistically significant within-group improvements in dual-task gait speed (4.2% and 8.3% respectively) after two weeks of intensive therapy.
No significant interaction effect was found between the two intervention types, meaning the trial does not establish that one approach was superior to the other for dual-task walking.
The trial did not include a no-treatment control group, so it cannot fully separate the effects of the interventions from natural improvement, practice, or other non-specific factors over the study period.
