Impact of social functioning and vitality on preference for life in patients with Parkinson's disease

High satisfaction and improved quality of life with Rock Steady Boxing in Parkinson's disease: results of a large-scale survey

PURPOSE

To compare demographics, self-reported symptom burden, Health-Related Quality of Life (HRQL), and Self-Efficacy for Exercise (SEE) between participants and non-participants of Rock Steady Boxing (RSB), a non-contact boxing program for individuals with Parkinson's disease (PD) that focuses on agility, balance, and speed training.

MATERIALS AND METHODS

Adults with PD who had heard of RSB completed a 20 min, 61-question electronic survey including the Parkinson's Disease Questionnaire-39 (PDQ-39) and the Self-Efficacy for Exercise (SEE) scale. Differences between participants and never-participants were analyzed using chi-squared test, fisher's exact test and Wilcoxon test.

RESULTS

Of 2054 individuals enrolled in the survey, 1709 were eligible for analysis. 1333 were current participants, 166 previous-participants, and 210 never-participants. RSB participants were median age 69, 59% male, and 97% Caucasian. The majority of current participants reported that RSB improved their social life (70%), fatigue (63%), fear of falling (62%), depression (60%), and anxiety (59%). Compared to previous and never-participants, current participants had better median PDQ-39 scores (36 and 32 vs 25, p < 0.01) and SEE scores (43 and 48 vs 54, p < 0.01).

CONCLUSIONS

This is the largest survey of RSB use in PD. RSB participants report improvement in non-motor impairments and have significantly better HRQL and ESE compared to never-participants.IMPLICATIONS FOR REHABILITATIONParkinson's disease (PD) is a slowly progressive neurodegenerative condition that affects motor function and subsequently, quality of life.Exercise is increasingly recognized as an important treatment for motor and non-motor symptoms of PD.Rock Steady Boxing (RSB) is a specific non-contact boxing program for PD that is growing and increasing in popularity, though there is limited data on its effect on PD symptoms and quality of life.

Health-related quality of life as a predictor of recurrent falling in Parkinson's disease: 1-year follow-up study

OBJECTIVE

The aim of this study was to assess whether various domains related to health-related quality of life could be predictive of recurrent falls among persons with Parkinson's disease (PD) during a 1-year follow-up study.

METHODS

A total of 120 consecutive persons with PD who had denied falling in past 6 months were recruited at regular check-ups at the Department of Movement Disorders, Neurology Clinic, Clinical Center of Serbia in Belgrade, from 15 August 2011 to 15 December 2012. At baseline, study participants were clinically assessed. Health-related quality of life was evaluated with the generic 36-item Short Form Health Survey. Participants were prospectively followed for 1 year, and occurrence of falls was registered.

RESULTS

The median age of subjects was 60.0 years, with a median disease duration of 4.0 years. Of 120 persons with PD, 42 (35%) experienced falls during the 12-month study period, including 23 (19.2%) who fell repeatedly. After adjustment for gender, age, PD duration, levodopa dosage, Hoehn and Yahr stage, Unified Parkinson's Disease Rating Scale I-IV, Hamilton Depression Rating Scale, and Hamilton Anxiety Rating Scales, we identified the 36-item Short Form Health Survey domains of role physical (P = 0.033) and vitality (P = 0.019) as being associated with recurrent falls of persons with PD within the 1-year follow-up period.

CONCLUSION

Baseline 36-item Short Form Health Survey scores regarding both the physical and mental components of overall health may be related to recurrent falling among persons with PD. These HRQoL domains could be considered as potential markers for persons with PD who are prone to recurrent falls.

Impact of Sex on the Nonmotor Symptoms and the Health-Related Quality of Life in Parkinson's Disease

Background. Female Parkinson's disease (PD) patients seem to experience not only more severe motor complications and postural instability but also more pronounced depression, anxiety, pain, and sleep disturbances. Objective. The aim of the present study was to evaluate the role of sex as a possible independent predictor of HRQoL in PD. Methods. In this cross-sectional study, 621 consecutive patients treated at the University of Pécs were enrolled. Severity of PD symptoms was assessed by MDS-UPDRS, UDysRS, Non-Motor Symptoms Scale, PDSS-2, Hamilton Anxiety Scale, Montgomery-Asberg Depression Rating Scale, Lille Apathy Rating Scale, and Addenbrooke Cognitive Examination. HRQoL was assessed by PDQ-39 and EQ-5D. Multiple regression analysis was performed to estimate the PDQ-39 and EQ-5D index values based on various clinical factors. Results. Although females received significantly lower dosage of levodopa, they had significantly more disabling dyskinesia and worse postural instability. Anxiety, pain, sleep disturbances, and orthostatic symptoms were more frequent among females while sexual dysfunction, apathy, and daytime sleepiness were more severe among males. Women had worse HRQoL than men (EQ-5D index value: 0.620 ± 0.240 versus 0.663 ± 0.229, p = 0.025, and PDQ-39 SI: 27.1 ± 17.0 versus 23.5 ± 15.9, p = 0.010). Based on multiple regression analysis, sex was an independent predictor for HRQoL in PD. Conclusions. Based on our results, female sex is an independent predictor for having worse HRQoL in PD.

Valuing Treatments for Parkinson Disease Incorporating Process Utility: Performance of Best-Worst Scaling, Time Trade-Off, and Visual Analogue Scales

OBJECTIVE

The objective of this study was to compare treatment profiles including both health outcomes and process characteristics in Parkinson disease using best-worst scaling (BWS), time trade-off (TTO), and visual analogue scales (VAS).

METHODS

From the model comprising of seven attributes with three levels, six unique profiles were selected representing process-related factors and health outcomes in Parkinson disease. A Web-based survey (N = 613) was conducted in a general population to estimate process-related utilities using profile-based BWS (case 2), multiprofile-based BWS (case 3), TTO, and VAS. The rank order of the six profiles was compared, convergent validity among methods was assessed, and individual analysis focused on the differentiation between pairs of profiles with methods used.

RESULTS

The aggregated health-state utilities for the six treatment profiles were highly comparable for all methods and no rank reversals were identified. On the individual level, the convergent validity between all methods was strong; however, respondents differentiated less in the utility of closely related treatment profiles with a VAS or TTO than with BWS. For TTO and VAS, this resulted in nonsignificant differences in mean utilities for closely related treatment profiles.

CONCLUSIONS

This study suggests that all methods are equally able to measure process-related utility when the aim is to estimate the overall value of treatments. On an individual level, such as in shared decision making, BWS allows for better prioritization of treatment alternatives, especially if they are closely related. The decision-making problem and the need for explicit trade-off between attributes should determine the choice for a method.

The role of social support in anxiety and depression among Parkinson's disease patients

PURPOSE

To explore how social support is associated with anxiety and depression in Parkinson's disease (PD) patients controlling for gender, disease duration and disease severity.

METHODS

The sample consisted of 124 patients (52.4% male; mean age 68.1 ± 8.4 years; mean disease duration 6.3 ± 5.5 years). Anxiety and depression were measured with the Hospital Anxiety and Depression Scale, social support with the Multidimensional Scale of Perceived Social Support and disease severity with the Unified Parkinson Disease Rating Scale. Data were analyzed using linear regression.

RESULTS

Gender, disease duration, disease severity and social support explained 31% of the total variance in anxiety in younger PD patients but did not significantly contribute to the explanation of depression. In the older group, this model explained 41% of the variance in depression but did not significantly contribute to the explanation of anxiety.

CONCLUSION

PD patients experience the positive influence of social support differently according to age. In the younger group, disease duration plays the primary role regarding anxiety. In the older group, poor social support especially from friends is associated with more depression after controlling for the relevant variables. Implications of Rehabilitation PD is a disease of older age with a neurodegenerative character and treatment should focus on increasing quality of life. Anxiety and depression are common co-morbidities in PD patients. The support network should also be screened regularly and involved in enhancing the quality of life.

Determinants of health-related quality of life in Parkinson's disease: a systematic review

This systematic review critically evaluates the literature to identify the demographic and clinical factors that predict the health-related quality of life (HRQOL) of people with Parkinson's disease (PD). Understanding how these factors relate to HRQOL in people with PD may assist clinicians minimise the functional and social impact of the disease by optimising their assessment and clinical decision making processes. A tailored search strategy in six databases identified 29 full-text reports that fulfilled the pre-defined inclusion and exclusion criteria. The quality of included studies was assessed by two independent reviewers using a customized assessment form. A best-evidence synthesis was used to summarise the demographic and clinical factors that were examined in relation to HRQOL. Depression was the most frequently identified determinant of HRQOL in people with idiopathic PD. Disease severity and disease disability were also found to be predictive of poor HRQOL outcomes in many studies. The motor symptoms that contributed most often to overall life quality were gait impairments and complications arising from medication therapy. To minimise the impact of PD on HRQOL, it may be necessary to consider the extent to which demographic factors and motor and non-motor symptoms contribute to life quality.

Impact of an exercise program on physical, emotional, and social aspects of quality of life of individuals with Parkinson's disease

We evaluated changes in different domains of quality of life (QL) for persons with Parkinson's disease after a program of physical activity. Twenty subjects with a diagnosis of Parkinson's disease classified as Stages 1 to 3 on the Hoehn and Yahr scale and with a mean age of 61.5 +/- 9.8 years participated in 36 group sessions of a combined group program of aerobic conditioning and muscular strengthening. QL was investigated by the Nottingham Health Profile, a generic questionnaire composed of six domains. Student's paired t tests indicated significant gains associated with the program (P < 0.05) on the total score and those related to emotional reactions (ER), social interactions (SI), and physical ability (PA). SI was the domain that showed the greatest program gains (41.4%). The program of physical activity performed with persons with Parkinson's disease at light to moderate stages resulted in improvements in their perception of QL, mainly in the domains of ER, SI, and PA.

Multicentre European study of thalamic stimulation in essential tremor: a six year follow up

BACKGROUND

Thalamic stimulation is an efficient treatment for disabling essential tremor, as previously shown, but follow up has mostly been short term.

OBJECTIVES

To see whether good results can be maintained in the longer term.

METHODS

37 patients with essential tremor had implantation of a thalamic stimulator, either unilaterally or bilaterally. The results at one year have been reported earlier. After six years, 19 patients were available for follow up. The main instrument for evaluation was the essential tremor rating scale. The patients were examined with pulse generators turned on and off.

RESULTS

In the majority of patients, the very good results with stimulation seen at one year were maintained after a mean of 6.5 years. The reduction in tremor scores and improvement in activities of daily living were highly significant compared with baseline and with the stimulation turned off. There were few serious adverse events. Minor side effects related to stimulation were common. Few device related complications were observed and most could be resolved.

CONCLUSIONS

Good reduction in tremor can be maintained for more than six years in the majority of these severely disabled patients. Thalamic stimulation can be recommended in essential tremor where there is insufficient response to drug treatment. Surgical procedures and follow up should be concentrated in relatively few centres, which will thereby acquire a high degree of expertise.
