Community-based exercise and wellness program for people diagnosed with Parkinson disease: experiences from a 10-month trial

Regular Exercise, Quality of Life, and Mobility in Parkinson's Disease: A Longitudinal Analysis of National Parkinson Foundation Quality Improvement Initiative Data

BACKGROUND

Research-based exercise interventions improve health-related quality of life (HRQL) and mobility in people with Parkinson's disease (PD).

OBJECTIVE

To examine whether exercise habits were associated with changes in HRQL and mobility over two years.

METHODS

We identified a cohort of National Parkinson Foundation Quality Improvement Initiative (NPF-QII) participants with three visits. HRQL and mobility were measured with the Parkinson's Disease Questionnaire (PDQ-39) and Timed Up and Go (TUG). We compared self-reported regular exercisers (≥2.5 hours/week) with people who did not exercise 2.5 hours/week. Then we quantified changes in HRQL and mobility associated with 30-minute increases in exercise, across PD severity, using mixed effects regression models.

RESULTS

Participants with three observational study visits (n = 3408) were younger, with milder PD, than participants with fewer visits. After 2 years, consistent exercisers and people who started to exercise regularly after their baseline visit had smaller declines in HRQL and mobility than non-exercisers (p < 0.05). Non-exercisers worsened by 1.37 points on the PDQ-39 and a 0.47 seconds on the TUG per year. Increasing exercise by 30 minutes/week was associated with slower declines in HRQL (-0.16 points) and mobility (-0.04 sec). The benefit of exercise on HRQL was greater in advanced PD (-0.41 points) than mild PD (-0.14 points; p < 0.02).

CONCLUSIONS

Consistently exercising and starting regular exercise after baseline were associated with small but significant positive effects on HRQL and mobility changes over two years. The greater association of exercise with HRQL in advanced PD supports improving encouragement and facilitation of exercise in advanced PD.

Physical Functioning After 1, 3, and 5 Years of Exercise Among People With Parkinson's Disease: A Longitudinal Observational Study

BACKGROUND AND PURPOSE

Regular physical activity is thought to be crucial to maintaining optimal physical function in people with Parkinson's disease (PWP), and it may have neuroprotective effects. As with many medical treatments, exercise is most effective when performed consistently over a period of years. The primary aim of this study was to examine multiyear adherence to a community-based group exercise program for PWP. A secondary aim was to document how physical functioning progressed after 1, 3, and 5 years for participants who consistently attended a community-based, group, exercise program.

METHODS

Forty-six individuals with idiopathic Parkinson's disease, who were at modified Hoehn and Yahr stage I, II, or III and were community ambulators, were recruited on a rolling basis between 2008 and 2013. Each provided yearly medical clearance to exercise. Participants engaged in a free, community-based, group exercise program offered 2 days per week, 1 hour per day, for three 10-week sessions per year. The program included supervised floor exercises for balance, coordination, strength, and flexibility along with resistance training on dual-action exercise machines. Participants who attended more than half the classes for 1, 3, or 5 years (n = 27, n = 14, n = 7, respectively) were considered to have completed the fitness program (consistent exercisers) and were included in the longitudinal data analysis; participants who either dropped out or attended less than half the classes (n = 19) were not included. Physical functioning was evaluated at baseline for all participants and yearly thereafter for consistent exercisers. Wilcoxon signed rank tests were used to compare baseline data with data collected after 1, 3, and 5 years of consistent exercise.

RESULTS AND DISCUSSION

Over half of the participants initially evaluated completed at least 1 year of the fitness program (27 of the 46 = 59%) and a proportion completed 3 years (14 of the 39 = 39%), and 5 years (7 of the 24 = 29%). At baseline, consistent exercisers were younger than those who dropped out (63.9 vs 69.9 years, P < .05), but had similar modified Hoehn and Yahr medians (2.0 vs 2.3), and similar time since diagnosis (8.0 vs 5.6 years). Consistent exercisers showed small statistically significant improvements in grip strength (8.9% change), Berg Balance scores (5.1% change), and 6-minute walk test (11% change) from baseline to year 1. No significant differences were found in these variables after 3 or 5 years, or for gait speed and timed up and go after 1, 3, or 5 years.

CONCLUSION

Despite the progressive nature of Parkinson's disease, many PWP can sustain a regular program of varied modes of community-based, group exercise over a period of years. Participants who did so maintained initial performance levels on key measures of physical functioning. By working with an interprofessional team in a supportive community-based exercise program, physical therapists can help many PWP engage in consistent and sustained exercise activity over multiyear periods.

Development of a community-based exercise program for people diagnosed and at-risk for Huntington's disease: A clinical report

BACKGROUND

Given the neurodegenerative nature of Huntington's disease (HD), community-based exercise programs that meet the ongoing needs of those living with HD are needed. The genetic nature of HD warrants the inclusion of those at-risk for HD. The purpose of this clinical report is to describe an evidence-based approach to the design of a community-based exercise program to improve gait, balance, and fatigue for individuals diagnosed with and at-risk for HD.

PROGRAM DESIGN

Based on the literature, clinical expertise and patient values, the program was designed to include four key features: (1) community-based group format for individuals with HD, caregivers, and those at-risk for HD; (2) individualized prescription within the group; (3) circuit training; and (4) use of outcome measures. PROGRAM IMPLEMENTATION AND OUTCOMES: The group met once weekly for 8 weeks for balance, strength, and cardiovascular fitness exercises. Three individuals participated, two diagnosed with HD and 1 considered "at-risk" for HD. Pre- and post- outcome measures included the 10 meter walk test, Berg Balance Scale, Fatigue Impact Scale, and the Timed Up and Go. Participants demonstrated improvement or maintenance of abilities in all measures with no adverse events.

DISCUSSION

This clinical report describes the integration of the evidence, clinical expertise, and patient values to develop and implement individualized, community-based exercise groups, aimed to improve balance, gait speed, and fatigue measures for persons with HD and those at-risk. Post-program reflections and recommendations for those who are interested in developing similar programs in other communities are described.

Are the effects of community-based dance on Parkinson disease severity, balance, and functional mobility reduced with time? A 2-year prospective pilot study

OBJECTIVE

To determine the effects of participation in a 2-year community-based dance class on disease severity and functional mobility in people with Parkinson disease (PD).

DESIGN

Randomized controlled trial.

SETTINGS/LOCATION

Dance classes took place in a community-based location. Outcome measures were collected in a university laboratory.

PATIENTS

Ten individuals with PD were randomly assigned to the Argentine tango (AT) group (n=5 [4 men]; mean age±standard deviation, 69.6±6.6 years) or the control group (n=5 [4 men]; mean age±standard deviation, 66±11.0 years).

INTERVENTIONS

The AT group participated in a community-based AT class for 1 hour twice weekly for 2 years. Control group participants were given no prescribed exercise. Blinded assessments occurred at baseline and 12 and 24 months.

OUTCOME MEASURES

Movement Disorder Society-Unified Parkinson Disease Rating Scale (MDS-UPDRS) III, Mini-Balance Evaluation Systems Test (Mini-BESTest), gait velocity (forward and backward), Timed Up and Go and dual-task Timed Up and Go, Six-Minute Walk Test (6MWT), MDS-UPDRS II, MDS-UPDRS I, and Freezing of Gait Questionnaire.

RESULTS

There were no differences between groups at baseline. A significant group-by-time interaction (F [2,8]=17.59; p<0.0001) was noted for the MDS-UPDRS III, with the AT group having lower scores at 12 and 24 months than the controls. Significant interactions were also noted for the Mini-BESTest, MDS-UPDRS II and I, and 6MWT.

CONCLUSION

This is believed to be one of the longest-duration studies to examine the effects of exercise on PD. Participation in community-based dance classes over 2 years was associated with improvements in motor and nonmotor symptom severity, performance on activities of daily living, and balance in a small group of people with PD. This is noteworthy given the progressive nature of PD and the fact that the control group declined on some outcome measures over 2 years.

Long-term exercise training for an individual with mixed corticobasal degeneration and progressive supranuclear palsy features: 10-year case report follow-up

BACKGROUND AND PURPOSE

This case report describes the effects of long-term (10-year) participation in a community exercise program for a client with mixed features of corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP). The effects of exercise participation on both functional status and brain volume are described.

CASE DESCRIPTION

A 60-year-old male dentist initially reported changes in gait and limb coordination. He received a diagnosis of atypical CBD at age 66 years; PSP was added at age 72 years. At age 70 years, the client began a therapist-led community group exercise program for people with Parkinson disease (PD). The program included trunk and lower extremity stretching and strengthening, upright balance and strengthening, and both forward and backward treadmill walking. The client participated twice weekly for 1 hour for 10 years and was reassessed in years 9 to 10.

OUTCOMES

Falls (self-reported weekly over the 10-year period of the study by the client and his wife) decreased from 1.9 falls per month in year 1 to 0.3 falls per month in year 10. Balance, walking endurance, and general mobility declined slightly. Gait speed (both comfortable and fast) declined; the client was unable to vary gait speed. Quantitative brain measurements indicated a slow rate of whole brain volume loss and ventricular expansion compared with clients with autopsy-proven CBD or PSP.

DISCUSSION

This client has participated consistently in a regular group exercise program for 10 years. He has reduced fall frequency, maintained balance and endurance, and retained community ambulation using a walker. Combined with the slow rate of brain volume loss, this evidence supports the efficacy of a regular exercise program to prolong longevity and maintain function in people with CBD or PSP.

The Effect of Parkinson Drug Timing on Cardiovascular Response during Treadmill Exercise in a Person with Parkinson Disease and Freezing of Gait

PURPOSE

To examine the response of cerebral oxygenation during treadmill walking in a person with Parkinson disease (PD) who experiences freezing of gait (FOG) and to determine whether the oxygen response was related to the timing of his PD medication. Client Description: A 61-year-old man with PD performed two bouts of treadmill testing on the same day, during the on- and off-phases of his PD medication. Measures and Outcome: The client experienced two FOG episodes during the first testing session (on-phase with hypokinetic movement session). Cerebral oxygen response (measured by near-infrared spectroscopy) was stable until the FOG episodes occurred, at which point it decreased until the FOG episode was over. No electrocardiogram (ECG) changes or lightheadedness were noted; blood pressure (BP) remained stable. During the second exercise testing session (off-phase with dyskinetic movement session), the client did not experience any FOG episodes, and his cerebral oxygen response remained stable. Toward the end of the second testing session, he experienced lightheadedness and a drop in BP of approximately 30 mmHg, along with significant ST segment depression on his ECG.

IMPLICATIONS

Haemodynamic and cerebral oxygen changes occurred that were specific to the timing of the client's PD medication and to his FOG episodes. This case study shows a person with PD demonstrating decreased cerebral oxygenation during FOG, which may be based on his variable response to levodopa medication or may be attributable to as yet unidentified physiologic mechanisms.

Therapeutic effects of tai chi in patients with Parkinson's disease

Objective. The purpose of the study was to investigate the effects of a 12-week program of therapeutic Tai Chi on the motor function and physical function of idiopathic Parkinson's disease patients (PDs). Methods. The participants were 22 clinically stable PDs in Hoehn-Yahr stages 1-2 randomly assigned to a therapeutic Tai Chi group (TTC, N = 11) or a control group (CON, N = 9). Two subjects in control group did not complete the study for personal reasons. TTC was performed three days a week (60 min/session). Motor symptoms by the UPDRS were assessed, and tests of physical function were administered before and after the 12-week trial. Results. The TTC group, as compared to the CON group, showed changes in the mentation, behavior, mood, and motor scales of the UPDRS (P < 0.05, P < 0.01, resp.), with no significant main effects on the activities of daily living scale (ADL). However, there was a significant interaction between the time and intervention group on ADL (P < 0.05). There were no significant main effects for any of the physical function variables. There were significant interaction effects in balance and agility (P < 0.05, resp.). Conclusions. This study showed that TTC training had modest positive effects on the functional status of Parkinson's disease patients.
