Falls in Parkinson's disease (PD) are common and frequently devastating. Falls prevention is an urgent priority, but there is no accepted program that specifically addresses the risk profile in PD. Therefore, we aimed to provide consensus-based clinical practice recommendations that systematically address potential fall risk factors in PD. We developed an overview of both generic (age-related) and PD-specific factors. For each factor, we specified: best method of ascertainment; disciplines that should be involved in assessment and treatment; and which interventions could be engaged. Using a web-based tool, we asked 27 clinically active professionals from multiple relevant disciplines to evaluate this overview. The revised version was subsequently reviewed by 12 experts. Risk factors and their associated interventions were included in the final set of recommendations when at least 66% of reviewing experts agreed. These recommendations included 31 risk factors. Nearly all required a multidisciplinary team approach, usually involving a neurologist and PD-nurse specialist. Finally, the expert panel proposed to first identify the specific fall type and to tailor screening and treatment accordingly. A routine evaluation of all risk factors remains reserved for high-risk patients without prior falls, or for patients with seemingly unexplained falls. In conclusion, this project produced a set of consensus-based clinical practice recommendations for the examination and management of falls in PD. These may be used in two ways: for pragmatic use in current clinical practice, pending further evidence; and as the active intervention in clinical trials, aiming to evaluate the effectiveness and cost-effectiveness of large scale implementation. 相似文献

BackgroundWe sought to define the frequency of falls in early PD and assess potential risk factors for falls in this population.MethodsWe analyzed the data from two randomized, placebo controlled trials (NET-PD FS1 and FS-TOO) of 413 individuals with early PD over 18 months of follow-up in FS1 and 12 months in FS-TOO. Falls were defined as any report of falls on the UPDRS or the adverse event log. We assessed the frequency of falls overall and by age. The relationship between prespecified fall risk markers and the probability of falling was assessed using logistic and multiple logistic regression. A hurdle Poisson model was used to jointly model the probability of remaining fall-free and the number of falls.ResultsDuring the follow-up period, 23% of participants fell, and 11% were habitual fallers. In a multiple logistic regression model, age, baseline UPDRS Falling score, and baseline PDQ-39 scores were associated with subsequent fall risk (p < 0.001). Similarly, in a hurdle Poisson regression model, age, baseline UPDRS falling item, and baseline PDQ-39 were all significantly related to the probability of falling, but only UPDRS falling >0 was associated with the number of falls.ConclusionFalls are frequent and are associated with impaired quality of life, even in early PD. Current standard rating scales do not sufficiently explain future fall risk in the absence of a prior fall history. New assessment methods for falls and postural instability are required to better evaluate this important problem in clinical trials and clinical practice. 相似文献

Falls are one of the most serious complications of gait disturbances in patients with Parkinson's disease (PD). Among previous
reports, the percentage of patients with PD who fall varies between 38% to 68%. We sought to determine the frequency of falls
and the factors associated with falls in a group of patients with idiopathic PD who attended an outpatient, tertiary movement
disorders clinic. 350 ambulatory, non–demented patients (230 males) were studied. Mean age was 69.7 ± 10.6 years (range: 43–97
yrs) and mean duration of PD symptoms was 8.6 ± 6.2 years (range: 1–33 yrs). Assessments included characterization of demographics,
disease duration, disease severity as measured by the Hoehn and Yahr Scale (H&Y), co–morbidities, the presence of depressive
symptoms, the presence of urinary incontinence, use of anti–parkinsonian medications, and two performance–based tests of balance
and gait (tandem standing and Timed Up & Go). Fall history was determined during three time periods: previous week, previous
month, and previous year. Univariate and multivariate logistic regression models were applied to evaluate the relationship
between the above–mentioned factors and falls. 46% of the subjects reported at least one fall in the previous year and 33%
reported 2 or more falls and were classified as Fallers. Fallers had significantly more prolonged and advanced PD compared
with Non–fallers (p = 0.001 and p < 0.001, respectively). Urinary incontinence was the factor most closely associated with
falls (crude and adjusted OR were 1.95 and 5.89, respectively). Other factors significantly associated with fall status included
increased Timed Up & Go times and increased PD duration. These findings confirm that falls are a common problem among patients
with advanced PD and suggest easily measurable features that may be used to prospectively identify those PD patients with
the greatest risk of falls. 相似文献

Recurrent falls are a disabling feature of Parkinson's disease (PD). We have estimated the incidence of falling over a prospective 3 month follow-up from a large sample size, identified predictors for falling for PD patients repeated this analysis for patients without prior falls, and examined the risk of falling with increasing disease severity. We pooled six prospective studies of falling in PD (n = 473), and examined the predictive power of variables that were common to most studies. The 3-month fall rate was 46% (95% confidence interval: 38-54%). Interestingly, even among subjects without prior falls, this fall rate was 21% (12-35%). The best predictor of falling was two or more falls in the previous year (sensitivity 68%; specificity 81%). The risk of falling rose as UPDRS increased, to about a 60% chance of falling for UPDRS values 25 to 35, but remained at this level thereafter with a tendency to taper off towards later disease stages. These results confirm the high frequency of falling in PD, as almost 50% of patients fell during a short period of only 3 months. The strongest predictor of falling was prior falls in the preceding year, but even subjects without any prior falls had a considerable risk of sustaining future falls. Disease severity was not a good predictor of falls, possibly due to the complex U-shaped relation with falls. Early identification of the very first fall therefore remains difficult, and new prediction methods must be developed. 相似文献

BACKGROUND AND PURPOSE: Falls are a common and serious problem among Parkinson's disease (PD) patients. However, knowledge about the causes and risk factors of falls is limited. There have been a few attempts to classify the causes of falls. The classification suggested by Olanow seems to be the most comprehensive one. The aim of this study was to analyze retrospectively the causes of falls and risk factors of falls in PD patients. MATERIAL AND METHODS: One hundred and four patients with moderately advanced PD were included in the study. The patients were asked to describe the circumstances and consequences of falls which occurred during 12 months preceding the examination. The falls were classified according to the Olanow classification of causes of falls. RESULTS: Fifty-two patients (50%) reported at least one fall during the previous year with a mean number of 1.5 falls per year. The most common causes of falls were environmental factors, sudden falls and postural instability. There were no falls caused by severe dyskinesia, drugs or cardiovascular disorders. The only independent risk factors of the recurrent falls identified in this study were UPDRS part II score (OR 1.17, 95% CI: 1.02-1.37) and Mini Mental State Examination score (OR 0.85, 95% CI: 0.72-0.99). CONCLUSIONS: Considering these results we may be able to prevent most falls by means of the education of patients about environmental factors and using adequate rehabilitation techniques concentrating on postural stability and gait. 相似文献

PurposeFall-related fracture is one of the most disabling features of idiopathic Parkinson's disease (PD). A better understanding of the associated factors is needed to predict PD patients who will require treatment.MethodsThis prospective study enrolled 100 adult idiopathic PD patients. Stepwise logistic regressions were used to evaluate the relationships between clinical factors and fall-related fracture.ResultsFalls occurred in 56 PD patients, including 32 with fall-related fractures. The rate of falls in the study period was 2.2 ± 1.4 per 18 months. The percentage of osteoporosis was 34% (19/56) and 11% in PD patients with and without falls, respectively. Risk factors associated with fall-related fracture were sex, underlying knee osteoarthritis, mean Unified Parkinson's Disease Rating Scale score, mean Morse fall scale, mean Hoehn and Yahr stage, and exercise habit. By stepwise logistic regression, sex and mean Morse fall scale were independently associated with fall-related fracture. Females had an odds ratio of 3.8 compared to males and the cut-off value of the Morse fall scale for predicting fall-related fracture was 72.5 (sensitivity 72% and specificity 70%).DiscussionHigher mean Morse fall scales (>72.5) and female sex are associated with higher risk of fall-related fractures. Preventing falls in the high-risk PD group is an important safety issue and highly relevant for their quality of life. 相似文献

The study aims were to devise (1) a fall risk screen for people with PD using routine clinical measures and (2) an explanatory (physiological) fall risk assessment for guiding fall prevention interventions. One hundred thirteen people with PD (age 66 ± 95% CI 1.6 years) underwent clinical assessments and quantitative tests of sway, gait, strength, reaction time, and lower limb sensation. Participants were then followed up for 12 months to determine fall incidence. In the follow‐up year, 51 participants (45%) fell one or more times whereas 62 participants (55%) did not fall. Multivariate analyses of routine clinical measures revealed that a fall in the past year, abnormal axial posture, cognitive impairment, and freezing of gait were independent risk factors for falls and predicted 38/51 fallers (75%) and 45/62 non‐fallers (73%). A multivariate model combining clinical and physiological measures that elucidate the pathophysiology of falls identified abnormal posture, freezing of gait, frontal impairment, poor leaning balance, and leg weakness as independent risk factors. This model correctly classified 39/51 fallers (77%) and 51/62 non‐fallers (82%). Patients with PD at risk of falls can be identified accurately with routine clinical assessments and quantitative physiological tests. Many of the risk factors identified are amenable to targeted intervention. © 2009 Movement Disorder Society 相似文献

BACKGROUND: Falls and fractures contribute to morbidity and mortality in bradykinetic rigid syndromes. METHODS: The authors performed a retrospective case notes review at the Queen Square Brain Bank for Neurological Disorders and systematically explored the relation between clinical features and falls and fractures in 782 pathologically diagnosed cases (474 with Parkinson's disease (PD); 127 progressive supranuclear palsy (PSP); 91 multiple system atrophy (MSA); 46 dementia with Lewy bodies (DLB); 27 vascular parkinsonism; nine Alzheimer's disease; eight corticobasal degeneration). RESULTS: Falls were recorded in 606 (77.5%) and fractures in 134 (17.1%). In PD, female gender, symmetrical onset, postural instability, and autonomic instability all independently predicted time to first fall. In PD, PSP, and MSA latency to first fall was shortest in those with older age of onset of disease. Median latency from disease onset to first fall was shortest in Richardson's syndrome (12 months), MSA (42), and PSP-parkinsonism (47), and longest in PD (108). In all patients fractures of the hip were more than twice as common as wrist and forearm fractures. Fractures of the skull, ribs, and vertebrae occurred more frequently in PSP than in other diseases. CONCLUSION: Measures to prevent the morbidity associated with falls and fractures in bradykinetic rigid syndromes may be best directed at patients with the risk factors identified in this study. 相似文献

IntroductionClinical staging of Parkinson's disease (PD) is important for patient management and prognosis. The non-motor and functional features visual hallucinations, recurrent falls, dementia and nursing home placement are currently not included in clinical staging schemes, but have been suggested as clinical milestones with important prognostic implications in advanced PD. In this study, we sought to evaluate the potential of these four milestone events for clinical staging and prognosis during the early years of the disease.MethodsWe recruited 185 patients with incident PD and monitored prospectively every six months through seven years for emergence and consequences of four clinical milestones.ResultsOne or more milestones were reached in 53.0%. Of the patients who reached the milestones, visual hallucinations appeared after a median of 3.3 (interquartile range 1.3–4.9) years from diagnosis, recurrent falls after 3.8 (2.8–5.2) years, dementia after 4.0 (2.1–4.8) years and nursing home placement after 5.4 (3.9–6.7) years. Presence of any milestone was associated with occurrence of other milestones (relative risks 1.9–6.3; all p ≤ 0.001). Experiencing two or more milestones increased the risk of death during the study (relative risk 2.7, p = 0.03).ConclusionsIn early PD, visual hallucinations, recurrent falls, dementia and nursing home placement appear closely interrelated, possibly reflecting a shared neuropathological disease stage. All events convey important and sinister information on PD status and prognosis and are relatively easily accessible during routine clinical consultations. Therefore, they appear highly useful as clinical PD milestones and could possibly be incorporated into a novel disease rating scale. 相似文献

BackgroundAlthough risk factors that lead to falling in Parkinson's disease (PD) have been previously studied, the established predictors are mostly non-modifiable. A novel method for fall risk assessment may provide more insight into preventable high-risk activities to reduce future falls.ObjectivesTo explore the prediction of falling in PD patients using a machine learning-based approach.Method305 PD patients, with or without a history of falls within the past month, were recruited. Data including clinical demographics, medications, and balance confidence, scaled by the 16-item Activities-Specific Balance Confidence Scale (ABC-16), were entered into the supervised machine learning models using XGBoost to explore the prediction of fallers/recurrent fallers in two separate models.Results99 (32%) patients were fallers and 58 (19%) were recurrent fallers. The accuracy of the model to predict falls was 72% (p = 0.001). The most important factors were item 7 (sweeping the floor), item 5 (reaching on tiptoes), and item 12 (walking in a crowded mall) in the ABC-16 scale, followed by disease stage and duration. When recurrent falls were analysed, the models had higher accuracy (81%, p = 0.02). The strongest predictors of recurrent falls were item 12, 5, and 10 (walking across parking lot), followed by disease stage and current age.ConclusionOur machine learning-based study demonstrated that predictors of falling combined demographics of PD with environmental factors, including high-risk activities that require cognitive attention and changes in vertical and lateral orientations. This enables physicians to focus on modifiable factors and appropriately implement fall prevention strategies for individual patients. 相似文献

We evaluated lower extremity isokinetic muscle strength to determine affected muscle groups and their dependence on movement velocity, and to establish the relationship between muscle strength and clinical severity, as well as muscle strength and falls, in Parkinson’s disease (PD). Twenty-five patients diagnosed with PD and 24 healthy volunteers were enrolled in this study. Lower extremity muscle strength was measured using an isokinetic dynamometer. Each participant’s clinical status was examined in accordance with the Unified Parkinson’s Disease Rating Scale; fall history was also recorded. We observed a significant decrease in isokinetic muscle strength in the patient group, especially in both hip and knee flexors and extensors. Decreased muscle strength was independent of velocity, and correlated with clinical severity and falls. Movement velocity-independent lower extremity isokinetic muscle weakness has been observed in patients with PD, especially in the knee and hip joints. The evaluation of isokinetic muscle strength may be a useful tool for the assessment of clinical severity and falls in PD. 相似文献

Background and purposeAlthough Parkinson disease (PD) patients suffer falls more frequently than other old people, only a few studies have focused on identifying the specific risk factors for falls in PD patients. The aim of this study was to assess the incidence and risk factors of falls in a prospective study in comparison to a control group.Material and methodsOne hundred patients with PD were recruited to the study along with 55 gender- and age-matched healthy controls. Both groups were examined twice; the second examination took place one year after the first one. Examination of the PD group included: medical history including falls, neurological examination, assessment of the severity of parkinsonism [Unified Parkinson's Disease Rating Scale (UPDRS), Schwab and England scale (S&E), Hoehn and Yahr scale (H&Y), Mini-Mental State Examination (MMSE)], Hamilton scale and quality of life scales (SF-36, EQ-5D) and Freezing of Gait Questionnaire (FOG-Q). In both groups falls were recorded over the 12 months. Frequent fallers are defined as having more than 3 falls a year.ResultsOver the year falls occurred in 54% of PD patients and 18% of controls. In a prospective study 28% of PD patients fell more frequently than in retrospective analysis. Frequent fallers were found in 20% of patients and in 7% of controls. Fallers showed higher scores in UPDRS, H&Y, S&E, MMSE, and Hamilton scale than non-fallers. Independent risk factors for falls were: age, previously reported falls and higher score in the FOG-Q.ConclusionsFalls in PD patients occurred three times more frequently than in controls. Independent risk factors for falls were: high score in FOG-Q, older age and presence of falls in medical history. 相似文献

A population-based study was designed to evaluate the clinical associates of postural sway and to identify the risk factors for falls in Parkinson's disease (PD). From a total population of 205,000 inhabitants, 215 PD patients were identified of which 120 home-dwelling cases were finally included in the study. Medical data were collected and patients were clinically examined and tested for static balance using an inclinometric device. Recent falls occurred in 40 (33%) of the subjects and 27 (23%) subjects were recurrent fallers. The fallers had a significantly larger sway area (P = 0.021) and a larger maximum deflection in anterior-posterior (P = 0.016) and lateral directions (P = 0.006) than the nonfallers. A significant correlation was found between the sway measures and the UPDRS total score, motor subcore and UPDRS "bradykinesia" item. A higher UPDRS total score (OR: 1.04, 95% CI: 1.01-1.07) and an increased sway area (OR: 1.25, 95% CI: 1.02-1.54) were independent risk factors for recent falling in PD. In addition, the duration and severity of PD, antiparkinsonian medication, recent falling and the use of a walking aid were associated with increased sway measures. The results can be used to identify PD patients who are at a risk of falling. Both antiparkinsonian medication and nonmedical treatment should be optimized to reduce falls in PD. 相似文献

The aims of this narrative review are to provide scientific support to characterize the postural instability commonly observed in Parkinson’s disease (PD), and to emphasize how bottom-up rehabilitation programs stimulating the sole of the foot can improve postural stability in PD. Postural instability is a typical characteristic of individuals with PD, which increases the frequency of falls and may worsen their consequences. It thus seems relevant to diagnose these alterations as early as possible, in order to develop specific rehabilitative treatment. The association between sensitivity of the sole of the foot and postural instability in individuals with PD is linked to the key role of peripheral alterations of the sensorimotor system in balance and motor symptoms. By enhancing sensory feedback coming from the feet, bottom-up stimulation allows patients to improve their sensorimotor control. In clinical practice, health practitioners can use sensory stimulation to improve postural control. By improving postural stability, a decrease in fall risk can be achieved and the secondary impairments associated with falls prevented. 相似文献

A growing body of research highlights the importance of cognition for prediction of falls in Parkinson's disease (PD). However, a previously proposed prediction model for future near falls and falls in PD, which includes history of near falls, tandem gait, and retropulsion, was developed without considering cognitive impairment. Therefore, by using a sample of 64 individuals with relatively mild PD and not excluding those with impaired cognition we aimed to externally validate the previously proposed model as well as to explore the value of additional predictors that also consider cognitive impairment. Since this validation study failed to support the proposed model in a PD sample including individuals with impaired global cognition, extended analyses generated a new model including dyskinesia (item 32 of Unified PD Rating Scale) and frontal lobe impairment (Frontal Assessment Battery—FAB) as significant independent predictors for future near falls and falls in PD. The discriminant ability of this new model was acceptable (AUC, 0. 80; 95% CI 0.68‐0.91). Replacing the continuous FAB scores by a dichotomized version of FAB with a cut‐off score ≤14 yielded slightly lower but still acceptable discriminant ability (AUC, 0. 79; 95% CI 0.68‐0.91). Further studies are needed to test our new model and the proposed cut‐off score of FAB in additional samples. Taken together, our observations suggest potentially important additions to the evidence base for clinical fall prediction in PD with concomitant cognitive impairment. 相似文献

Falls among persons with Parkinson’s disease (PD) often result in activity limitations, participation restrictions, social isolation or premature mortality. The purpose of this 1-year follow-up study was to compare potential differences in features of PD attributing to falls in relation to fall location (outdoor vs. indoor). We recruited 120 consecutive persons with PD who denied having fallen in the past 6 months. Disease stage and severity was assessed using the Hoehn and Yahr scale and the newer version of the Unified Parkinson’s Disease Rating Scale. Occurrence of falling and characteristics of falls was followed for 1 year. Results were assessed statistically. Outdoor falls were more commonly preceded by the extrinsic factors (tripping and slipping). Slipping was more common outdoors (p = 0.001). Indoor falls were mostly preceded by the intrinsic factors (postural instability, lower extremity weakness, vertigo). Vertigo was more common indoors (p = 0.006). Occurrence of injuries was more common after outdoor falls (p = 0.001). Indoor falls resulted in contusions only, while outdoor falls resulted in lacerations and fractures as well. In the regression model adjusted for age, disease duration, on/off phase during fall, Hoehn and Yahr stage of disease and levodopa dosage, slipping was associated with outdoor falling (odds ratio = 17.25, 95 % confidence interval 3.33–89.20, p = 0.001). These findings could be used to tailor fall prevention program with emphasis on balance recovery and negotiation of objects in environment. 相似文献

The purpose of this study was to investigate the relationship between fear of falling and fall frequency among patients with
idiopathic Parkinson’s disease (PD). One hundred-two participants with idiopathic PD were interviewed and examined. Participants
reported the number of falls they had experienced in the preceding 3 months. They completed a mini-mental state exam (MMSE)
and the falls efficacy scale (FES) questionnaire. Disease severity was determined by clinical examination using the Hoehn-Yahr
staging system. Excluding two outliers who fell more than once each day, the subjects fell an average of 1.2 times in a 3 month
period. There was a positive correlation between the number of falls, freezing of gait and Hoehn-Yahr score, and a negative
correlation with the MMSE. In a post-hoc analysis the participants were divided into four groups based on fall frequency.
The outliers had the lowest FES scores on average, similar to the scores seen in the rare fallers group. This study suggests
that many factors are associated with fear of falling, including fall frequency, disease severity, and mental status. In the
present study, the patients who fell the most often did not report the most fear. The lack of fear of falling but frequent
falls in this small subgroup may suggest that special techniques to instill suitable caution to prevent falls are necessary,
or may make training of these patients impossible. 相似文献

IntroductionFalls severely affect lives of Parkinson's disease (PD) patients. Cognitive impairment including dual-tasking deficits contribute to fall risk in PD. However, types of dual-tasking deficits preceding falls in PD are still unclear.MethodsWalking velocities during box-checking and subtracting serial 7s were assessed twice a year in 40 PD patients over 2.8 ± 1.0 years. Fourteen patients reported a fall within this period (4 excluded fallers already reported falls at baseline). Their dual-task costs (DTC; mean ± standard deviation) 4.2 ± 2.2 months before the first fall were compared with 22 patients never reporting falls. ROC analyses and logistic regressions accounting for DTC, UPDRS-III and disease duration were used for faller classification and prediction.ResultsOnly walking/box-checking predicted fallers. Fallers showed higher DTC for walking while box-checking, p = 0.029, but not for box-checking while walking, p = 0.178 (combined motor DTC, p = 0.022), than non-fallers. Combined motor DTC classified fallers and non-fallers (area under curve: 0.75; 95% confidence interval, CI: 0.60–0.91) with 71.4% sensitivity (95%CI: 41.9%–91.6%) and 77.3% specificity (54.6%–92.2%), and significantly predicted future fallers (p = 0.023). Here, 20.4%-points higher combined motor DTC (i.e. the mean difference between fallers and non-fallers) was associated with a 2.6 (1.1–6.0) times higher odds to be a future faller.ConclusionMotor dual-tasking is a potentially valuable predictor of falls in PD, suggesting that avoiding dual task situations as well as specific motor dual-task training might help to prevent falls in PD. These findings and their therapeutic relevance need to be further validated in PD patients without fall history, in early PD stages, and with various motor-motor dual-task challenges. 相似文献

Matinolli M, Korpelainen JT, Sotaniemi KA, Myllylä VV, Korpelainen R. Recurrent falls and mortality in Parkinson’s disease: a prospective two‐year follow‐up study. Acta Neurol Scand: 2011: 123: 193–200.© 2010 John Wiley & Sons A/S. Objectives – To evaluate the risk factors for recurrent falling and mortality in Parkinson’s disease (PD) in a prospective study design. Materials and methods – One hundred and twenty‐five PD patients were included in the study. Baseline medical data were collected, and patients were clinically tested for mobility and balance. Falls were prospectively recorded for 2 years. Mortality was documented 4 years after the baseline. Results – Seventy‐nine patients reported altogether 3125 falls during the follow‐up, and 59 patients were classified as recurrent fallers. Altogether 126 fall injuries including six fractures were reported. Eighteen patients had died by the time of the hospital chart review. History of falling (OR 3.02, 95% CI 1.23–7.44) and the Unified Parkinson’s Disease Rating Scale activities of daily living score (OR 1.13, 95% CI 1.04–1.22) were independent risk factors for recurrent falling in PD, whereas slow walking speed (OR 16.28, 95% CI 1.85–142.97) was an independent risk factor for mortality in PD. Conclusions – History of falling and disease severity indicate increased risk of recurrent falls in PD, while patients with slow walking speed may have an increased risk of mortality. Recurrent falling was not associated with increased risk of mortality in PD in this study. 相似文献

The aim of this study was to investigate the prevalence of the different causes of falling in Parkinson's disease (PD) and to evaluate the influence of falls on patients' quality of life (QoL). We recruited 60 PD patients (31 with falls, 29 without falls). We found that falls were caused by: unstable posture (29.0%), freezing or festination (25.8%), sudden loss of postural reflexes (toppling falls) (25.8%), co-existing neurological disorders (6.5%), cardiological disorders (6.5%), and symptomatic orthostatic hypotension (3.2%). Duration of the disease was longer, its stage more advanced, daily levodopa dosage higher, and the proportion of patients with abnormalities in the EEG apparently greater in the group with falls. The presence of falls was found to be a factor contributing to a multidirectional negative impact on patients' QoL. QoL also depended on impairment of cognitive function, daily dosage of levodopa, disease duration, disease progression, and sex. The results of this study underline the need to diagnose the causes of falls in order to institute appropriate treatment and to improve patients' QoL. 相似文献
