- Brief Summary
The purpose of this single-blinded, randomized controlled study aims to establish the effects of functional postural control training on functional performance and FOG in PD individuals with FoG as compared with treadmill training.
- Detailed Description
Background and purpose: Freezing of gait (FoG), is a common sign in patients with Parkinson's disease (PD), especially at the advanced stage. Advanced functional activities, such as dual task walking, turning, or crossing a door often induce the FOG. FoG is a complex phenomenon which pathophysiology is currently unknown. However, previous studies have found that postural instability may be a risk factor for FoG. In addition, previous studies have suggested the interactions between FoG and postural instability. Treadmill training has been shown to be relatively more effective to improve FoG than other interventions. On the other hand, postural control training was demonstrated to improve the severity of FoG and postural control in freezers. However, no study has investigated the effectiveness of functional postural control training on functional performance and FOG. Therefore, this study aims to establish the effects of functional postural control training on functional performance and FOG in PD individuals with FoG as compared with treadmill training.
Methods: This study is a single-blinded randomized controlled trial. Twenty PD people with FoG will be recruited and randomized to the experimental and control group. The experimental group will receive functional postural control training, and the control group will receive treadmill training. Each intervention is 30 minutes/ session, 3 sessions/ weeks, for 4 weeks. The primary outcome is functional performance, which will measure the walking speed, cadence, and step length in the four conditions, including (1) Time up and go test, (2) Dual task Time up and go test, (3) 360º turning in place, and (4) Walking through the door. The secondary outcome is the severity of FoG which is assessed by the New Freezing of Gait Questionnaire (NFOGQ). All outcomes will be assessed before and after the training program. Demographic data at baseline will be analyzed by using Chi-square test or independent T-test. Two-way repeated ANOVA will be performed to analyze the primary and secondary outcomes. The significance level is set at p\<0.05.

Group Intervention Description Treadmill training Treadmill training The subjects in the control group performed a 30-minute walking session on a treadmill at a self-selected speed. Functional postural control training Functional postural control training The training includes (1) Maintaining a stationary posture in a standing position for a total of 10 minutes, (2) Posture control training involving unilateral lower limb stepping movements for a total of 10 minutes, and (3) Advanced walking task training, including sudden stops, turns, ball raises, and obstacle crossing during walking, for a total of 10 minutes.
