Effects of Task-Based LSVT-BIG Intervention on Hand Function, Activity of Daily Living, Psychological Function, and Quality of Life in Parkinson’s Disease: A Randomized Control Trial

Physical Exercise for Treating the Anxiety and Depression Symptoms of Parkinson's Disease: Systematic Review and Meta-Analysis

BACKGROUND

Depression and anxiety are non-motor symptoms of Parkinson's disease (PD). Physical exercise is a promising approach to reducing neuropsychological burden. We aimed to comprehensively synthesize evidence regarding the use of exercise for treating depression and anxiety symptoms in PD.

METHODS

Systematic review and meta-analysis following PRISMA recommendations. Searches on PubMed, Cochrane Library, Scopus, Web of Science, Embase, and Physiotherapy Evidence Database (PEDro) was conducted. The random-effects model was employed for all analyses with the standardized mean difference as the effect estimate.

RESULTS

Fifty records were retrieved, but only 17 studies met the criteria for the meta-analyses. A moderate to large effect was observed for depression (-.71 [95% CI = -.96 to -.46], 11 studies, 728 individuals), and a small to moderate effect for anxiety (-.39 [95% CI = -.65 to -.14], 6 studies, 241 individuals), when comparing exercise to non-exercise controls. Subgroup analysis revealed significant effects from aerobic (-.95 [95% CI = -1.60, -.31]), mind-body (-1.85 [95% CI = -2.63, -1.07]), and resistance modalities (-1.61 [95% CI = -2.40, -.83]) for depression, and from mind-body (-.67 [95% CI = -1.19 to -.15]) and resistance exercises (-1.00 [95% CI = -1.70 to -.30]) for anxiety.

CONCLUSION

Physical exercise has a relevant clinical impact on depression and anxiety in PD. We discuss the level of the evidence, the methodological limitations of the studies, and give recommendations.

Developing SSC program for disabled elderly to promote ADL independence in nursing home using MRC framework for complex interventions

OBJECTIVE

To develop SSC program for promoting the independence of disabled elderly in Activities of Daily Living (ADL) care in nursing homes.

METHODS

This intervention aligns with the Medical Research Council (MRC) Framework for complex interventions. The following three steps were undertaken: (1) identifying the evidence base; (2) identifying/developing theory; (3) modeling processes and outcomes.

RESULTS

We successfully developed the complex intervention program of self-supporting care (SSC). The program comprises two integral parts: (1) self-supporting care interventions (SSC-i); (2) self-supporting care implementation interventions (SSC-ii).

CONCLUSIONS

Through adherence to the MRC framework, an evidence-based SSC program for managing ADL among disabled elderly individuals in nursing homes was developed. These findings offer a detailed specification of the SSC intervention protocol, which can serve as a valuable resource for healthcare professionals and researchers in subsequent phases, particularly in pilot testing the efficacy of the intervention and promote independence among disabled elderly individuals.

Practitioner perspectives on the implementation of the Lee Silverman Voice Treatment BIG® program

Background

The Lee Silverman Voice Treatment BIG® (LSVT BIG®) intervention, originally designed for the patients with Parkinson's disease, is a high amplitude, high repetition therapy protocol that encourages bigger, more quality movements. The purpose of this study was to understand practitioner utilization and perspectives of the LSVT BIG® intervention as there is no published work in this area.

Methods

An electronic survey with optional debriefings was distributed to LSVT BIG® certified practitioners via the Facebook page run by parent company, LSVT Global Inc.

Results

Forty-seven practitioners engaged in this study. Practitioners were largely in the outpatient setting. Forty-seven percent reported utilizing the LSVT BIG® intervention for patient populations outside of the Parkinson's disease diagnosis. Sixty-one percent of respondents reported using the same assessment tools and ninety-five percent reported billing insurance for their services. Twenty-three percent reported offering the LSVT BIG® intervention via telehealth. Debriefings identified barriers to implementation.

Conclusion

Practitioners are implementing the LSVT BIG® intervention across settings and are most likely to be in the outpatient setting, serving patients who possess a neurological diagnosis, and focus their assessment on lower extremity, gait, and balance. When billing insurance, practitioners routinely select the three CPT® codes: Neuromuscular Re-Education, Therapeutic Activity, and Therapeutic Procedure/Exercise. Practitioners identified several barriers to implementing the LSVT BIG® program, such as the high frequency of in-clinic visits. Practitioners are currently unsystematically modifying the program to meet patient and practitioner needs. Further research should continue to explore the practitioner perspectives on implementation of the LSVT BIG® intervention.

The impact of fatigue severity and depression level on the quality of life in individuals with Parkinson's disease in Taiwan

Background

Patients diagnosed with Parkinson's disease undergo alterations in physical, psychological, and social functionality, with the psychological domain being particularly predisposed to inducing fatigue and depressive symptoms. Understanding the alterations occurring within a patient's body and mind and how these influence their overall quality of life is crucial.

Purpose

This study sought to explore the predictive capacity of fatigue severity, the presence of depressive symptoms, and diverse demographic factors on the quality of life among individuals with Parkinson's disease.

Methods

A cross-sectional correlational study was conducted at a teaching hospital in southern Taiwan. The research utilized a questionnaire survey to interview 133 study participants, focusing on the Quality of Life Scale, Depression Scale, Fatigue Severity Scale, Social Support Scale, and demographic attributes.

Results

A total of 130 valid questionnaires were obtained. The results showed that Hoehn and Yahr stage, fatigue severity, and depression status could predict quality of life, explaining 51.1% of the total variance. These findings suggest that patients at advanced Hoehn and Yahr stages, experiencing more severe fatigue, and exhibiting higher levels of depression, tended to report a lower overall quality of life. Our findings suggest that, in addition to Hoehn and Yahr stage, the severity of fatigue and levels of depression significantly impact the quality of life in individuals with Parkinson's disease.

Conclusion

Nurses need to understand the "stressful life events" and the changes in appearance and physical function that patients with Parkinson's disease face due to chronic degenerative diseases. Hence, apart from addressing patients' physiological needs, healthcare professionals should also offer appropriate care for psychological issues, such as depressive symptoms. Encouraging patients to participate in "counseling groups" can further bolster their social support networks, enhancing their overall well-being and addressing comorbidities associated with chronic degenerative diseases.

Effects of Upper Limb Exercise or Training on Hand Dexterity and Function in People With Parkinson Disease: A Systematic Review and Meta-analysis

OBJECTIVE

This systematic review investigated the effects of exercise and training on hand dexterity and function outcomes in people with Parkinson disease (PD).

DATA SOURCES

We searched 5 databases (MEDLINE Ovid, CINAHL, PEDro, PubMed, Cochrane Database) from inception to October 2022.

STUDY SELECTION

Included studies were randomized controlled trials delivering upper limb exercise or training interventions to people with PD and evaluating 1 or more upper limb activity outcomes. Two independent reviewers screened 668 articles for inclusion.

DATA EXTRACTION

Two reviewers independently extracted data relating to study participants, intervention characteristics, and key outcomes. Cochrane Risk of Bias and GRADE tools assessed methodological quality of included studies, and strength of evidence for 3 outcomes: hand dexterity, self-reported hand function, and handwriting performance. Meta-analyses synthesized results for within-hand dexterity and self-reported function.

RESULTS

Eighteen randomized controlled trials (n=704) with low to unclear risk of bias were identified. Experimental interventions varied considerably in their approach and treatment dose, and 3 studies focused on training handwriting. Meta-analysis showed moderate quality evidence of a small positive effect on within-hand dexterity (SMD=0.26; 95% CI 0.07, 0.44). Very low-quality evidence pointed toward a nonsignificant effect on self-reported hand function (SMD=0.67; 95% CI -0.40, 1.75). A narrative review of handwriting interventions showed low quality evidence for improved performance after training.

CONCLUSIONS

There is moderate certainty of evidence supporting the use of exercise and training to address dexterity problems, but evidence remains unclear for self-reported hand function and handwriting. Our findings suggest that training could employ task-related approaches. Future research should interrogate aspects of clinical practice such as optimal dose and key ingredients for effective interventions.

The effects of standard and modified LSVT BIG therapy protocols on balance and gait in Parkinson's disease: A randomized controlled trial

BACKGROUND

Lee Silverman voice treatment (LSVT) BIG is an exercise program developed for patients with Parkinson's disease (PwPD), consisting of sets of exercises performed for 4 consecutive days a week for 4 weeks. However, the standard protocol suggests a treatment frequency difficult to follow for most patients who have difficulties reaching rehabilitation clinics. Our aim was to compare the standard LSVT BIG protocol with a modified LSVT (m-LSVT) BIG protocol (twice a week in the clinic for 4 weeks and twice a week at home for 4 weeks).

METHODS

In this randomized controlled trial, 16 PwPD (aged 18-80 years, Hoehn and Yahr stages I-III) were recruited into two groups. The LSVT group received standard LSVT BIG training (four times per week for 4 weeks at the clinic). The other group was given m-LSVT BIG exercises, but unlike the LSVT group, the m-LSVT group exercised twice a week at the clinic and twice a week at home for 4 weeks. The Berg Balance Scale was used to assess functional balance. Biodex Balance System was used to assess laboratory balance measures. Timed Up and Go test and G-Walk sensor system were used to assess functional mobility and spatiotemporal gait analysis.

RESULTS

Significant group-by-time interactions on the eyes open-firm surface score of the modified clinical test of sensory integration of balance (F = 10.138, p = .007) and gait cycle symmetry index (F = 10.470, p = .010) were found to be in favor of the LSVT group. Additionally, post hoc analyses revealed that both groups significantly improved postural stability, gait speed, motor symptoms, and functional mobility (p < .05).

CONCLUSION

The results revealed the beneficial effects of the modified protocol on balance and gait in PwPD, as well as the superiority of the standard LSVT BIG protocol. The m-LSVT BIG protocol may be an effective intervention method, especially for PwPD who have difficulty adapting to the treatment frequency of the standard protocol.

Specialized Allied Health Care for Parkinson's Disease: State of the Art and Future Directions

People with Parkinson's disease (PD) experience a range of progressive motor and non-motor symptoms, that negatively affect their daily functioning, social participation and quality of life. Allied health therapies have emerged as an effective treatment approach-complementary to pharmacological and neurosurgical treatments-which reduces the impact of PD in daily life. In this article, we propose criteria for what constitutes specialized allied health care for PD, and we review allied health research in PD in terms of meeting these criteria and its outcomes for monodisciplinary approaches as well as multi- or interdisciplinary allied health interventions. We focus on the three most studied allied health disciplines in PD: physical therapy, occupational therapy and speech-language therapy. Overall, the available evidence underscores the importance and potential benefits of specialized allied health care for people with PD. Our proposed criteria and recommendations for future research might help in further delineating specialized allied health care.

Updates in Parkinson's Disease Integrative Therapies: an Evidence-Based Review

PURPOSE OF REVIEW

This review summarizes recent evidence-based integrative therapies for Parkinson's disease (PD) that may improve motor and non-motor symptoms, enhance quality of life, and alter disease progression.

RECENT FINDINGS

Imaging studies have demonstrated that aerobic exercise changes brain structure and function, while strength training improves posture and balance. Loneliness is associated with worsening PD severity, but social prescribing and cognitive behavioral therapy may effectively foster connections. Ayurvedic and traditional Chinese medicine practices including yoga, meditation, tai chi, and acupuncture may help improve mobility, mood, sleep, and quality of life. Art therapy enhances visuospatial skills, whereas music and dance therapy can alleviate freezing of gait. Several studies demonstrate successful use of these integrative strategies virtually, thereby improving patient accessibility and participation. PD management has broadened to include integrative approaches combining conventional and complementary therapies. Potential benefits of movement, nutrition, sleep, socialization, and mind-body practices have been confirmed with several recent randomized controlled trials.

Pharmacological and Non-Pharmacological Treatments for Depression in Parkinson's Disease: An Updated Review

Depression represents one of the most common non-motor disorders in Parkinson's disease (PD) and it has been related to worse life quality, higher levels of disability, and cognitive impairment, thereby majorly affecting not only the patients but also their caregivers. Available pharmacological therapeutic options for depression in PD mainly include selective serotonin reuptake inhibitors, serotonin and norepinephrine reuptake inhibitors, and tricyclic antidepressants; meanwhile, agents acting on dopaminergic pathways used for motor symptoms, such as levodopa, dopaminergic agonists, and monoamine oxidase B (MAO-B) inhibitors, may also provide beneficial antidepressant effects. Recently, there is a growing interest in non-pharmacological interventions, including cognitive behavioral therapy; physical exercise, including dance and mind-body exercises, such as yoga, tai chi, and qigong; acupuncture; therapeutic massage; music therapy; active therapy; repetitive transcranial magnetic stimulation (rTMS); and electroconvulsive therapy (ECT) for refractory cases. However, the optimal treatment approach for PD depression is uncertain, its management may be challenging, and definite guidelines are also lacking. It is still unclear which of these interventions is the most appropriate and for which PD stage under which circumstances. Herein, we aim to provide an updated comprehensive review of both pharmacological and non-pharmacological treatments for depression in PD, focusing on recent clinical trials, systematic reviews, and meta-analyses. Finally, we discuss the pharmacological agents that are currently under investigation at a clinical level, as well as future approaches based on the pathophysiological mechanisms underlying the onset of depression in PD.

Quantitative assessment of the gait improvement effect of LSVT BIG® using a wearable sensor in patients with Parkinson's disease

Background

The main effects of Lee Silvermann Voice Treatment-BIG® therapy (LSVT-BIG) on gait function are improvements in gait speed and stride length. Considering the mechanism of this improvement, LSVT-BIG may affect joint angles of the lower extremities. Therefore, further investigation of the effect of LSVT-BIG on gait function, especially joint angles, is needed.

Methods

Patients with Parkinson's disease (PD) who were eligible for LSVT-BIG were recruited. We measured the following items pre- and post-LSVT-BIG: MDS-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), Functional Independence Measure (FIM), timed up and go test (TUG), and gait parameters using RehaGait®. Gait parameters included gait speed, stride duration and length, the standard deviation of stride duration and length, cadence, the ratio of the stance/swing phase, and the flexion and extension angles of the hip, knee, and ankle joints. Range of motion (ROM) was calculated as the difference of values between the maximum flexion and extension angles of each joint.

Results

Twenty-four participants completed the LSVT-BIG. Significant improvement was observed in the MDS-UPDRS (mean changes: Part I, -2.4 points; Part II, -3.5 points; Part III -8.9 points), TUG (-0.61 s), gait speed (+0.13 m/s), stride length (+0.12 m), flexion and extension angles and ROM of the hip joints (flexion, +2.0°; extension, +2.0; ROM, +4.0°). Enlargement in ROM of the hip joint was strongly correlated with increase in gait speed and stride length (r = 0.755, r = 0.804, respectively).

Conclusions

LSVT-BIG enlarged flexion and extension angles and ROM of the hip joint significantly. Change of ROM of the hip joint was directly related to the increase in stride length and gait speed observed in patients with PD after LSVT-BIG.
