Quantitative clinical assessment of motor function during and following LSVT-BIG® therapy

"TiC-TUG": technology in clinical practice using the instrumented timed up and go test-a scoping review

Digitized assessments have a considerable potential to guide clinicial decision making and monitor progress and disease trajectories. The Timed Up and Go test (TUG) has been long established for assessment in geriatric medicine and instrumented versions (iTUG) have been developed and validated. This scoping review includes studies that applied the iTUG and aims to identify use cases to show where and how iTUG assessment could guide interventions and clinical management. The literature search was limited to peer-reviewed studies that performed pre- and post-intervention measurements with a 3-meter TUG instrumented with body-worn technology in samples of at least 20 subjects aged 60+ years. Of 3018 identified articles 20 were included. Four clinical use cases were identified: stratification for subsequent therapy, monitoring of disease or treatment-associated changes and evaluation of interventions in patients with idiopathic normal pressure hydrocephalus (1), and patients with Parkinson's disease (2); monitoring after joint replacement surgery (3), and evaluation after different exercise and rehabilitation interventions (4). The included studies show diversity in terms of iTUG technology and procedures. The identified use cases highlight clinical relevance and high potential for the clinical application of the iTUG. A consensual approach as well as comprehensive reporting would help to further exploit the potential of the iTUG to support clinical management. Future studies should investigate the benefits of segmental iTUG analysis, responsiveness and participants' perspectives on clinically meaningful changes in iTUG.

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.

A review of combined neuromodulation and physical therapy interventions for enhanced neurorehabilitation

Rehabilitation approaches for individuals with neurologic conditions have increasingly shifted toward promoting neuroplasticity for enhanced recovery and restoration of function. This review focuses on exercise strategies and non-invasive neuromodulation techniques that target neuroplasticity, including transcranial magnetic stimulation (TMS), vagus nerve stimulation (VNS), and peripheral nerve stimulation (PNS). We have chosen to focus on non-invasive neuromodulation techniques due to their greater potential for integration into routine clinical practice. We explore and discuss the application of these interventional strategies in four neurological conditions that are frequently encountered in rehabilitation settings: Parkinson's Disease (PD), Traumatic Brain Injury (TBI), stroke, and Spinal Cord Injury (SCI). Additionally, we discuss the potential benefits of combining non-invasive neuromodulation with rehabilitation, which has shown promise in accelerating recovery. Our review identifies studies that demonstrate enhanced recovery through combined exercise and non-invasive neuromodulation in the selected patient populations. We primarily focus on the motor aspects of rehabilitation, but also briefly address non-motor impacts of these conditions. Additionally, we identify the gaps in current literature and barriers to implementation of combined approaches into clinical practice. We highlight areas needing further research and suggest avenues for future investigation, aiming to enhance the personalization of the unique neuroplastic responses associated with each condition. This review serves as a resource for rehabilitation professionals and researchers seeking a comprehensive understanding of neuroplastic exercise interventions and non-invasive neuromodulation techniques tailored for specific diseases and diagnoses.

Effect of the Lee Silverman Voice Treatment BIG® on motor symptoms in a participant with progressive supranuclear palsy: A case report

BACKGROUND

Although the Lee Silverman Voice Treatment BIG® (LSVT BIG®) improves motor symptoms in patients with Parkinson's Disease, no reports exist for patients with Progressive Supranuclear Palsy (PSP).

OBJECTIVE

To describe the effect of LSVT BIG® on the motor symptoms of a participant with PSP.

CASE DESCRIPTION

The participant was a 74-year-old man with PSP. His goals were to improve limb movement, balance ability, and festinating gait over the 4-week LSVT BIG® program.

OUTCOMES

All assessments of limb movement and balance ability showed improvements after intervention for the limb and gait subsections of the PSP rating scale. Scores improved from 9 to 5, and 8 to 6, respectively for the Unified Parkinson's Disease Rating Scale (UPDRS) Part 3, from 30 to 21 and for the Berg balance scale (BBS), from 45 to 50 points. The improvements in UPDRS Part 3 and BBS exceeded the minimum detectable change values (7-8 and 2 points, respectively). After intervention, improvements in festinating gait and rapid walking pace were noted on the UPDRS Part 3 (2 to 1 point) and 10-meter walk test (1.65 m/s to 1.10 m/s).

CONCLUSION

The intervention was effective for the participant but further studies with diverse populations are needed.

Waist-What? Can a single sensor positioned at the waist detect parameters of gait at a speed and distance reflective of older adults' activity?

One of the problems facing an ageing population is functional decline associated with reduced levels of physical activity (PA). Traditionally researcher or clinician input is necessary to capture parameters of gait or PA. Enabling older adults to monitor their activity independently could raise their awareness of their activitiy levels, promote self-care and potentially mitigate the risks associated with ageing. The ankle is accepted as the optimum position for sensor placement to capture parameters of gait however, the waist is proposed as a more accessible body-location for older adults. This study aimed to compare step-count measurements obtained from a single inertial sensor positioned at the ankle and at the waist to that of a criterion measure of step-count, and to compare gait parameters obtained from the sensors positioned at the two different body-locations. Step-count from the waist-mounted inertial sensor was compared with that from the ankle-mounted sensor, and with a criterion measure of direct observation in healthy young and healthy older adults during a three-minute treadmill walk test. Parameters of gait obtained from the sensors at both body-locations were also compared. Results indicated there was a strong positive correlation between step-count measured by both the ankle and waist sensors and the criterion measure, and between ankle and waist sensor step-count, mean step time and mean stride time (r = .802-1.0). There was a moderate correlation between the step time variability measures at the waist and ankle (r = .405). This study demonstrates that a single sensor positioned at the waist is an appropriate method for the capture of important measures of gait and physical activity among older adults.

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.

Postural control of Parkinson's disease: A visualized analysis based on Citespace knowledge graph

Postural control impairment is one of the primary motor symptoms in patients with Parkinson's disease, leading to an increased risk of falling. Several studies have been conducted on postural control disorders in Parkinson's disease patients, but no relevant bibliometric analysis has been found. In this paper, the Web of Science Core Collection database was searched for 1,295 relevant papers on postural control in Parkinson's disease patients from December 2011 to December 2021. Based on the Citespace knowledge graph, these relevant papers over the last decade were analyzed from the perspectives of annual publication volume, countries and institutes cooperation, authors cooperation, dual-map overlay of journals, co-citation literature, and keywords. The purpose of this study was to explore the current research status, research hotspots, and frontiers in this field, and to provide a reference for further promoting the research on postural control in Parkinson's disease patients.

Effects of LSVT-BIG via telerehabilitation on non-motor and motor symptoms and quality of life in Parkinson's disease

BACKGROUND

Parkinson's disease (PD) is a neurodegenerative disease with motor and non-motor symptoms affecting the quality of life. This study aimed to investigate the effects of the Lee Silverman Voice Therapy (LSVT)-BIG rehabilitation program via telerehabilitation on quality of life, motor and non-motor symptoms in people with Parkinson's disease (PwPD), and their correlation with each other.

METHODS

Fifteen patients with mild-to-moderate PD (Hoehn and Yahr stages 1-3) were included in the LSVT-BIG exercise program with remote access for 16 sessions over four weeks. Motor and non-motor experiences before and after the program were evaluated with MDS-UPDRS parts 1, 2, and 3 and quality of life with PDQ-39. The correlation between MDS-UPDRS parts and PDQ-39 subgroups was examined.

RESULTS

Following the application of the LSVT-BIG rehabilitation program with remote access, MDS-UPDRS parts 1, 2, and 3 scores and PDQ-39 summary index (PDQ-39 SI) and subgroup scores (excluding social support) were improved. A moderate-strong correlation was determined between MDS-UPDRS parts 1 and 2 and the PDQ-39 parameters of the patients.

CONCLUSION

Both motor and non-motor symptoms may be associated with the quality of life in PD. We have concluded that LSVT-BIG treatment via telerehabilitation can improve motor and non-motor symptoms along with the quality of life in PwPD.

Impact of LSVT-BIG ® on functional mobility, walking, dexterity, and quality of life in Parkinson's disease

Purpose: The aim of this study was to evaluate the impact of the LSVT-BIG ® (Lee Silverman Voice Treatment Big) technique on functional mobility, dexterity, and quality of life in Parkinson's disease (PD). Materials and Methods: Fifteen patients with Parkinson's disease (9 males, and 6 females, aged 40-75 years; Hoehn & Yahr Stages I-III) completed a 4-week LSVT-BIG training program for 1 hour/session, 4 sessions per week. Parkinson's Disease Quality of Life Questionnaire-39 (PDQ-39) was used in measuring patients' quality of life at the beginning (t0) and at the end (t1) of the rehabilitation program. Nine-Hole Peg Test (NHPT) was used for dexterity. 10 Meter Walking Test (10MWT), Timed-Up-and-Go Test (TUG), and Five-Times Sit-to-Stand Test (5XSST) were used for assessing functional mobility. After 4 weeks, all participants were retested. Results: After 4 weeks of LSVT-BIG therapy, a statistically significant improvement was found in PDQ-39 mobility, activities of daily living, emotional state, stigma, cognition, communication, physical discomfort, and general scores after exercise compared to before. There was no statistically significant change in the PDQ-39 social support score after exercise compared to before. In addition, functional mobility improved as indicated by the TUG test, 5XSST, 10MWT (and dexterity by NHPT on the left. Conclusion: LSVT-BIG training may be a new therapeutic option for better walking, functional mobility, and manual capability performance and for enhancing the quality of life in PD. Randomized controlled trials with bigger sizes are needed to evaluate the effect of the LSVT-BIG rehabilitation program on reducing motor and non-motor impairments in patients with PD.

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

Previous studies have demonstrated that the Lee Silverman Voice Treatment-BIG (LSVT-BIG) program can improve motor functions such as balance and gait in Parkinson’s disease (PD) patients. However, no study has investigated the effects of a task-based LSVT-BIG intervention on hand function, psychological function, and quality of life in PD patients. Herein, we investigate the effects of a task-based LSVT-BIG intervention, which reflects the needs of PD patients, on hand function, activity of daily living (ADL), psychological function, and quality of life. A total of 14 PD patients were enrolled and randomly assigned to the experimental or control group. The experimental group performed 30 minutes of conventional occupational therapy and 40 minutes of the task-based LSVT-BIG program. The control group performed 30 minutes of conventional occupational therapy and 40 minutes of relaxation and stretching. Both groups underwent the respective interventions once a day 5 times a week for 4 weeks. As a result of the study, the experimental group showed improvement in hand function in both the dominant and nondominant hand, and the control group showed improvement only in the nondominant hand ( $p<.05$ ). ADL was significantly improved in both groups, but the experimental group showed a more statistically significant difference than the control group ( $p<.05$ ). Depression and anxiety were significantly decreased in both the experimental group and the control group, and in particular, in the case of anxiety, there was a more statistically significant difference in the experimental group ( $p<.05$ ). In the case of the experimental group, there was a significant improvement in quality of life in all items, and in the control group, except for the social function item ( $p>.05$ ), there was a significant improvement in other items ( $p<.05$ ). The results of this study suggest that the task-based LSVT-BIG program, which consists of activities desired by the participants, may be an effective intervention to improve hand function, ADL, psychological function, and quality of life in PD patients.

Occupational Therapy Practice Guidelines for People With Parkinson's Disease

IMPORTANCE

Occupational therapy practitioners address the occupational performance and participation needs of people with Parkinson's disease (PD) and their care partners.

OBJECTIVE

This Practice Guideline is informed by systematic reviews on the use of occupational therapy interventions to promote participation in occupations for people with PD and to facilitate their caregivers' participation in the caregiver role. This guideline is meant to support practitioners' clinical decision making when working with people with PD and their care partners.

METHOD

We examined and synthesized the results of four systematic reviews and integrated those results into clinical recommendations for practice.

RESULTS

Thirty-three articles from the systematic reviews served as the basis for the clinical recommendations in this Practice Guideline. Clinical recommendations are provided for interventions that have strong or moderate supporting evidence.

CONCLUSION AND RECOMMENDATIONS

Multidisciplinary, tailored, goal-oriented intervention is recommended for people with PD. Various forms of exercise can be used to improve activities of daily living and instrumental activities of daily living performance and social participation, and interventions should incorporate health behavior change techniques to support adequate physical activity levels in daily life. Mindfulness meditation and exercise can be used to support sleep, and task-oriented training can be used to improve performance of specific tasks. Occupational therapy practitioners should incorporate self-management, coaching, compensatory, cognitive-behavioral, and other approaches into multicomponent treatment plans depending on the client's needs and goals. Additional potentially appropriate intervention approaches or areas to address are discussed on the basis of existing or emerging evidence and expert opinion. What This Article Adds: This Practice Guideline provides a summary and applications of the current evidence supporting occupational therapy intervention for people with PD. It includes case examples and suggested decision-making algorithms to support practitioners in addressing client goals.

Effect of Exercise and Rehabilitation Therapy on Risk of Hospitalization in Parkinson's Disease

Background

Exercise and physical therapy (PT) can improve motor function and quality of life in individuals with Parkinson's disease (PD), but their role in hospitalization avoidance is not well-studied.

Objectives

To determine the longitudinal and temporal association of exercise and PT use with hospital encounter.

Methods

Longitudinal regression and χ2 analyses were performed on Parkinson's Foundation Parkinson's Outcome Project exercise and PT use data from 4674 and 9259 persons with PD, respectively.

Results

Greater exercise duration and intensity were associated with reduced odds of hospital encounter, whereas both PT and occupational therapy use were associated with increased odds. In the 2 years before a hospital encounter, there was an increased frequency of PT use, but not reductions in exercise.

Conclusions

Consistent exercise may reduce hospitalization risk whereas PT referral may identify at-risk individuals without preventing this outcome. Further work to incentivize consistent exercise in PD may reduce healthcare use.

The Cost of Gait Slowness: Can Persons with Parkinson's Disease Save Energy by Walking Faster?

BACKGROUND

Gait slowing is a common feature of Parkinson's disease (PD). Many therapies aim to improve gait speed in persons with PD, but goals are often imprecise. How fast should each patient walk? And how do persons with PD benefit from walking faster? There is an important need to understand how walking speed affects fundamental aspects of gait-including energy cost and stability-that could guide individualized therapy decisions in persons with PD.

OBJECTIVE

We investigated how changes in walking speed affected energy cost and spatiotemporal gait parameters in persons with PD. We compared these effects between dopaminergic medication states and to those observed in age-matched control participants.

METHODS

Twelve persons with PD and twelve control participants performed treadmill walking trials spanning at least five different speeds (seven speeds were desired, but not all participants could walk at the fastest speeds). Persons with PD participated in two walking sessions on separate days (once while optimally medicated, once after 12-hour withdrawal from dopaminergic medication). We measured kinematic and metabolic data across all trials.

RESULTS

Persons with PD significantly reduced energy cost by walking faster than their preferred speeds. This held true across medication conditions and was not observed in control participants. The patient-specific walking speeds that reduced energy cost did not significantly affect gait variability metrics (used as proxies for gait stability).

CONCLUSION

The gait slowing that occurs with PD results in energetically suboptimal walking. Rehabilitation strategies that target patient-specific increases in walking speed could result in a less effortful gait.

Effect of LSVT® BIG on standing balance in a Parkinson's patient: A case report

BACKGROUND AND PURPOSE

There are no reports regarding the effect of Lee Silverman Voice Treatment® BIG (LSVT® BIG) on standing balance ability evaluated using quantitative assessment. This case report aimed to describe and evaluate the influence of LSVT® BIG on the center of pressure (COP) trajectory in a patient with Parkinson's disease (PD).

METHODS

Although this paper focused on one case, quantitative assessment on the effect of LSVT® BIG on standing balance ability was performed. A 67-year-old woman patient diagnosed with PD at age 59, with a Hoehn and Yahr stage 3 disability severity, underwent a 4-weeks supervised LSVT® BIG program. The total distances of the COP trajectory (two-dimensional [2D] horizontal plane, anterior-posterior [AP] direction, and medial-lateral [ML] direction), and the mean COP velocity for each direction, postural stability, and posture subsections of the Unified Parkinson's Disease Rating Scale (UPDRS) Part 3 were assessed at pre- and post-intervention.

RESULTS

The total distances of the COP trajectory, mean COP velocities, and scores of postural stability and posture subsections of the UPDRS Part 3 improved after intervention (from 124.6 to 76.6 cm [2D], 89.4 to 57.7 cm [AP], 77.4 to 38.5 cm [ML]; 4.0 to 2.6 cm/s [2D], 3.0 to 1.9 cm/s [AP], 2.6 to 1.3 cm/s [ML]; and 3 to 0, and 3 to 2, respectively).

DISCUSSION

LSVT® BIG may be effective in improving the total distance of the COP trajectory, mean COP velocity, and both postural stability and posture subsections of the UPDRS Part 3 in the presented PD case.
