In a nutshell
This study investigated if postural perturbations during treadmill training (PPTT) improved gait in patients with Parkinson's disease (PD). Researchers suggested that PPTT improves the movement symptoms of these patients.
Parkinson's disease (PD) affects the brain cells causing symptoms such as muscle weakness, impaired balance and abnormal gait (walking). The drugs available to treat these symptoms are only of limited effectiveness. Therefore, physical training therapies are being more used.
PPTT includes walking on the treadmill (non-stop moving belt on which to walk or run) while things being put in your way to disturb the walking. Prior studies showed how this can improve the gait and balance of patients. Even though treadmill training is commonly used, PPTT has never been studied in patients with PD.
Methods & findings
The objective of this study was to investigate the effectiveness of PPTT in treating gait disorders in patients with PD.
This study included 38 patients. Of these, 18 received PPTT and 20 received standard treadmill training. These patients were followed-up for 3 months. Movement disability, postural and gait stability were assessed.
Treadmill training improved the symptoms of both groups of patients. These effects were greater in the PPTT group. The PPTT showed 38% fewer symptoms while the standard group showed 22% fewer symptoms.
In the PPTT group, 50% fewer gait disorder symptoms and 40% fewer postural symptoms were seen. These were compared to 22% fewer gait symptoms and 33% fewer postural symptoms in the standard group. Positive effects lasted after 3 months.
The bottom line
This study concluded that PPTT is associated with improved gait and balance in patients with Parkinson's disease.
The fine print
This study had a limited number of participants. Larger studies are needed for stronger evidence.
