Automated mechanical peripheral stimulation for gait rehabilitation in Parkinson's disease: A comprehensive review

Background

Automated Mechanical Peripheral Stimulation (AMPS) has emerged as a potential rehabilitative intervention for gait abnormalities in Parkinson's disease (PD). However, the long-term effects and combined therapy with physical exercise remain unclear. This review aimed to explore the effects of automated mechanical peripheral stimulation (AMPS) on gait and motor performance in individuals with Parkinson's disease (PD).

Methods

A research was conducted in relevant databases to identify studies investigating the effects of AMPS on gait and motor outcomes in PD patients. Inclusion criteria were set based on Population, Concept, and Context (PCC) criteria. Data extraction and analysis were performed to synthesize the findings.

Results

Ten studies met the inclusion criteria and were included in the review. The studies collectively demonstrated positive effects of AMPS on gait parameters, such as walking velocity, stride length, and walking stability. Some studies also reported improvements in functional performance and muscle activation during walking.

Conclusions

The findings suggest that AMPS holds promise as a potential intervention to improve gait and motor performance in individuals with PD. However, the evidence is limited, and further well-designed randomized controlled trials are needed to establish the long-term efficacy and optimal protocols for AMPS in PD rehabilitation.

Rising From the Floor in Persons With Parkinson's Disease

Although considerable research has targeted fall prevention among older adults with Parkinson's disease (PD), less is known about their ability to rise from the floor. The aim of the current exploratory study was to examine the relationship between floor rise and physical performance tests. A cross-sectional design was used. Twenty community-dwelling older adults with PD (mean age = 74.8 years, SD = 9.5 years) performed a standardized floor rise test and physical performance assessments in a structured task circuit. Mean time to rise from the floor was 14.9 seconds (SD = 7.6 seconds). Fourteen (70%) participants used a quadruped strategy to rise to stand. Supine-to-stand performance time was significantly correlated with all physical performance measures. Findings serve as a catalyst for nursing and rehabilitation professionals to examine floor rise ability, prevent adverse effects of a critical fall, and instruct fall recovery techniques in clinical settings.

Effects of automatic mechanical peripheral stimulation on gait biomechanics in older adults with Parkinson's disease: a randomized crossover clinical trial

BACKGROUND

Automated mechanical peripheral stimulation (AMPS) is a rehabilitation technique suggested to correct gait abnormalities on Parkinson's disease. Although previous studies have suggested increments in functional performance and gait speed after AMPS intervention, little is known about its effect on gait biomechanics.

OBJECTIVE

To analyze the effect of an AMPS session on functional performance and gait biomechanics in subjects with Parkinson's disease.

METHODS

Twenty-eight subjects aged 67±3 years old participated in this study. Kinematics and muscle activation were recorded during walking at a preferred gait speed before and after AMPS and sham interventions. Footswitches sensors were used to record the kinematic parameters. Electromyographic (EMG) signals of tibialis anterior (TA) and gastrocnemius lateralis (GL) were recorded. Timed up and go (TUG) test and Short Physical Performance Battery (SPPB) were performed to assess functional performance.

RESULTS

GL activation increased after AMPS intervention before and after heel strike (p = 0.04; p < 0.01) and before and after toe-off (p = 0.013; p = 0.038). Also, after AMPS intervention, TA activation increased after heel strike (p = 0.007); and after sham intervention, TA activation reduced before and after heel strike (p = 0.038; and p = 0.007) and before toe-off (p = 0.013). The time of TUG test was shorter after AMPS intervention (p = 0.015).

CONCLUSION

AMPS intervention changed the EMG activation of ankle muscles during walking and functional performance. However, AMPS intervention did not change gait kinematics.

Exercise for Older Adults Improves the Quality of Life in Parkinson's Disease and Potentially Enhances the Immune Response to COVID-19

Parkinson’s disease (PD) is a progressive neurodegenerative disorder brought about due to dopaminergic neuronal cell loss in the midbrain substantia nigra pars compacta region. PD presents most commonly in older adults and is a disorder of both motor and nonmotor dysfunction. The novel SARS-CoV-2 virus is responsible for the recent COVID-19 pandemic, and older individuals, those with preexisting medical conditions, or both have an increased risk of developing COVID-19 with more severe outcomes. People-with-Parkinson’s (PwP) of advanced age can have both immune and autonomic nervous problems that potentially lead to pre-existing pulmonary dysfunction and higher infection risk, increasing the probability of contracting COVID-19. A lifestyle change involving moderate-intensity exercise has the potential to protect against SARS-CoV-2 through strengthening the immune system. In addition to a potential protective measure against SARS-CoV-2, exercise has been shown to improve quality-of-life (QoL) in PD patients. Recent studies provide evidence of exercise as both neuroprotective and neuroplastic. This article is a literature review investigating the role exercise plays in modifying the immune system, improving health outcomes in PwP, and potentially acting as a protective measure against SARS-Cov-2 infection. We conclude that exercise, when correctly performed, improves QoL and outcomes in PwP, and that the enhanced immune response from moderate-intensity exercise could potentially offer additional protection against COVID-19.
