Brief Summary

Exercises that involve increasing the speed of movements are beneficial for individuals with Parkinson's disease (PD) and have the potential to reduce bradykinesia and improve mobility. High-speed bodyweight resistance training is a treatment that involves increasing speed considered accessible and viable as it can be performed at any time and place, including at home. This treatment has already shown benefits in the elderly individuals, however no studies were found in individuals with PD. Therefore, the primary aim of this study will be to investigate the effects of home-based and remotely supervised high-speed bodyweight resistance training in reducing bradykinesia in individuals with PD. The secondary aim will be to investigate the effects of home-based and remotely supervised high-speed bodyweight resistance training in improving mobility, muscle power, dynamic balance, and quality of life in this population. A randomized controlled trial will be carried out with concealed allocation, blinded assessments, and intention-to-treat analysis. Altogether, 46 individuals with PD (age ≥ 50 years old, who are bradykinetics and sedentary or insufficiently active will be included. Participants will be randomly assigned to either an experimental group (high-speed bodyweight resistance training) or a control group (bodyweight intervention, usual speed). Both groups will perform a home-based and remotely supervised intervention, consisting of 60-min individual sessions, three times per week over 12 weeks, with a trained physiotherapist. Primary outcomes are bradykinesia of the lower limbs and mobility. Secondary outcomes are muscle power, dynamic balance, and quality of life. Between-group differences will be measured by two-way repeated measures ANOVA, considering the baseline, post-training, and 4-week follow-up. The findings of this trial have the potential to provide important insights regarding the effects of high-speed bodyweight resistance training in reducing bradykinesia and improving mobility in individuals with PD. High-speed bodyweight resistance training does not use any type of external resistance and can be performed anywhere and at any time. In addition, it can be performed at home through telemonitoring, reducing time and costs of transport, making it quite feasible and accessible for individuals from different social and economic backgrounds which increases the feasibility of reproducing their findings in clinical practice.

Detailed Description

The sample size calculation was performed considering the primary outcome measures bradykinesia (assessed using items 3.8, 3.9, 3.10, and 3.14 of the motor examination of the MDS-UPDRS) based on data provided by previous similar randomized controlled trial. The effect size for bradykinesia was derived from a previous study. In that study, the groups showed a difference in means of -2.3 (treatment effect), using a standard deviation of 2.5, a significance level (α) of 5% and a power of 0.80, a sample size of 40 participants are required. Assuming a dropout rate of 15%, a total of 46 participants will be recruited (23 per group).

All statistical analyses will be performed by an independent examiner, blinded to the group allocation. All data analyses will be performed using SPSS for Windows (SPSS, Chicago, IL, USA). Descriptive statistics will be calculated for all outcomes. The effects of the interventions will be analyzed from the collected data using intention-to-treat. For dropouts, data from the last available assessment will be used for missed sessions. Two-way ANOVA with repeated measures will be used to evaluate the differences between groups, considering the time factor (pre-intervention, post-intervention, and follow-up), followed by post hoc test selected based on final sample size and in the assumption of equal of variance. If necessary, a similar nonparametric test will be used. The level of significance will be set at 5%.

Study Groups

High-speed bodyweight resistance training

The participants of the experimental group (high-speed bodyweight resistance training) will receive a home-based intervention that will include 5 minutes of warm-up (free active movements of trunk and lower limbs), followed by 50 min of exercises more targeted to the lower limb muscles, and by 5 minutes of cool-down (lower limb muscle stretching and relaxation breathing exercise).

The experimental intervention will be performed at maximum speed. During the initial home visit, the speed at which the participant can perform one set of each exercise at maximum speed will be timed. Speed-based progression will be determined every four weeks by increasing the number of repetitions in each set of exercises performed during subsequent home visits.

Group Type: EXPERIMENTAL

High-speed bodyweight resistance training

Intervention Type: OTHER

The participants of the experimental group (high-speed bodyweight resistance training) will receive a home-based intervention that will include 5 minutes of warm-up (free active movements of trunk and lower limbs), followed by 50 min of exercises more targeted to the lower limb muscles, and by 5 minutes of cool-down (lower limb muscle stretching and relaxation breathing exercise).

The experimental intervention will be performed at maximum speed. During the initial home visit, the speed at which the participant can perform one set of each exercise at maximum speed will be timed. Speed-based progression will be determined every four weeks by increasing the number of repetitions in each set of exercises performed during subsequent home visits.

Control group (Bodyweight intervention, usual speed)

The participants of the control group (Bodyweight intervention, usual speed) will also receive a home-based intervention that will include 5 minutes of warm-up (free active movements of trunk and lower limbs), followed by 50 min of exercises more targeted to the lower limb muscles, and by 5 minutes of cool-down (lower limb muscle stretching and relaxation breathing exercise).

The control intervention will be performed at the usual speed. The same procedures that will be carried out to determine the maximum speed in the experimental group will be used to determine the usual speed in the control group. There will be no progression in the speed of performing the exercises. However, participants in the control group will also receive a home visit from the main researcher every four weeks to avoid bias related to the amount of attention given to participants in the experimental group.
