- Background: Diabetes is associated with systemic complications. Prevalence of diabetic nephropathy, and retinopathy, in type 1 diabetes is declining but it is not known if this is true also for diabetic neuropathy.Aim: To investigate the relationship between large fiber diabetic neuropathy and other diabetic complications.Materials and methods: Neuropathy, defined here as large fiber neuropathy, was assessed by measuring vibration perception thresholds at four different frequencies on the sole of the foot using a standard VibroSense Meter and/or neuropathic symptoms, in 599 type 1 diabetic individuals. Retinopathy status was graded using the International Clinical Disease Severity Scale. Grade of albuminuria and previous history of any macrovascular complications, were registered.Results: Diabetic individuals without retinopathy had similar vibration thresholds as age- and gender-matched control persons without diabetes, whereas those without microalbuminuria had higher thresholds than controls. Two persons out of 599 (0.3%) had microalbuminuria, but not retinopathy or neuropathy, and 12/134 (9%) without retinopathy had signs of neuropathy. Totally 119/536 (22%) of the patients without microalbuminuria had neuropathy. Vibration thresholds increased with rising severity of retinopathy and grade of albuminuria. In a multinomial logistic regression analysis, neuropathy was associated with retinopathy (OR 2.96 [1.35-6.49], p=0.007), nephropathy (OR 6.25 [3.21-12.15]; p=6.7x10-8) and macrovascular disease (OR 2.72 [1.50-4.93], p=0.001).Conclusions: Despite recent changes in the incidence of diabetic complications, the onset of large fiber neuropathy follows that of retinopathy but precedes the onset of nephropathy in type 1 diabetes.

- BackgroundThe knowledge about striatal hand deformities (SHD) in Parkinson’s disease (PD), has recently increased but need more attention due to their early impact on dexterity. The focus of clinical studies has been on the staging of SHD severity and neurological features. However, a hand surgical perspective has not been considered.ObjectivesOur purpose was to examine SHD in patients with PD using hand surgical assessmentmethods and the recommended staging of SHD.MethodsIn this observational study, a specialist in neurological physiotherapy examined 100 consecutive PD patients and identified 35 with suspected SHD, who were thenexamined by two hand surgeons. Their hands were clinically evaluated for severity of SHD, according to a previous proposed staging, focusing on metacarpophalangeal (MCP) joint flexion, presence of intrinsic and extrinsic tightness, as well as other hand deformities.ResultsThree kinds of deformities were identified among 35 included patients: surgicaldiagnoses unrelated to PD (n=5), SHD (n=23), and PD related hand deformities with increased extrinsic tightness (n=10); three of these 10 patients had also contralateral SHD, thus are included in SHD group. In addition to previously described MCP joint flexion, swan neck deformity and z-thumb deformity, we found in most hands finger “clefting”, abduction of the little finger and/or an increased intrinsic tightness, indicating pathology of intrinsic muscles of the hand involved in SHD.ConclusionsSHD diagnosed with a modified staging method, including features of intrinsic andextrinsic hand deformities, should be considered in PD to implement early and more accurate treatment

- Introduction: Peripheral neuropathy (PN) becomes more common with increasing life expectancy, but general population prevalence estimates are lacking. We investigated an epidemiological distribution of signs of PN among 2,996 community-dwelling participants in Good Aging in Skåne Study, age 60–97, and their impact on physical and autonomic function. Methods: Signs of PN were measured with Utah Early Neuropathy Scale (UENS). Associations between UENS and physical tests, pain, and dysautonomic phenomena were calculated for each sex, adjusted for age, with estimated marginal means (EMM) and odds ratios (ORs) in four UENS quantiles (Q1–Q4). Results: Participants in Q4 had worse EMM for: time to complete Timed Up and Go test (Q4–Q1: male 10.8–9.6 s; female 11.7–10.2 s), 15 m Walk test (Q4–Q1: male 11.1–9.9 s; female 11.2–10.4 s), and fewer repetitions in Step test (Q4–Q1: male 15.2–17.0 steps; female 14.5–15.8 steps). Higher OR of failing one-leg balance 60 s test {male 2.5 (confidence interval [CI] 95%: 1.7–3.8); female 2.1 (1.1–3.2)}, Foam Pad Balance test (male 4.6 [CI 95%: 3.2–6.7]; female 1.8 [1.3–2.6]), and lower physical quality of life were seen in Q4 compared to Q1. Participants in Q4 had higher OR for walking aid usage, falls, fear of falling, pain, and urinary incontinence, while in males, higher OR for orthostatic intolerance, fecal incontinence, and constipation. Conclusions: In a general population, 20–25% of older adults who have highest UENS scores, a sensitive measure of early PN, express slower gait, worse balance, lower quality of life, pain, falls and fear of falling, and autonomic symptoms.

- People with Parkinson’s disease (PwPD) have an increased risk for falls and near falls. They have particular difficulties with maintaining balance against an external perturbation, and several retropulsion tests exist. The Unified PD Rating Scale item 30 (UPDRS30) is the most common, involving an expected shoulder pull. Others recommend using an unexpected shoulder pull, e.g., the Nutt Retropulsion Test (NRT). We aimed to evaluate the clinical usefulness of these tests for detecting future fallers. By using two different golden standards related to self-reported prospective falls and near falls over 6 months following two different time points with 3.5 years between, we estimated sensitivity/specificity, Youden index, predictive values, and likelihood ratios for each test. The different time points yielded a different prevalence of falls and near falls, as well as different predictive values. When comparing the performance of the NRT and UPDRS30 for detecting future fallers, we found that the NRT consistentlyperformed better than UPDRS30. However, neither test exhibited optimal performance in terms of predictive values and associated likelihood ratios. Our findings speak against using either of these tests as a single assessment for this purpose and support previous recommendations of using a multifactorial approach when targeting balance problems in PwPD.

- Objective: To investigate the association of different aspects of cognitive impairment, depression and anxiety with walking difficulties in daily life in persons with mild PD.Background: Walking difficulties in daily life are common among persons with Parkinson’s disease (PD) and may cause falls and near falls, limitations in activity, restrictions in participation and decrease in quality of life. Motor symptoms are often cited as a major reason for these difficulties while the association with cognitive and psychiatric symptoms is still poorly explored.Methods: The study included cross-sectional data from 73 persons with PD that visited a neurology outpatient clinic during 2012-2017. Mean (SD) age was 69 (8.9) years, mean (SD) disease duration was 8 (4.3) years and mean (SD) “on” phase motor symptoms (Unified PD Rating Scale, UPDRS, part III) and cognition (Mini Mental State Examination, MMSE) were 16.4 (9.9) and 27.3 (2.6), respectively. Walking difficulties in daily life (the dependent variable) was investigated with the generic Walk-12 (Walk-12G). Multiple linear regression analysis (controlling for age and motor symptoms) included the following independent variables: cognition (MMSE), memory (Alzheimer's Disease Assessment Scale, ADAS, cognitive subscale), cognitive perception speed (A Quick Test of Cognitive Speed, AQT, part I-III) frontal lobe/executive impairment (Frontal Assessment Battery, FAB) and depression and anxiety (Hospital Anxiety and Depression Scale, HADS). Results: The median Walk-12G scores was 11.5 (q1-q3, 5.5−25.5). Four significant independent variables were identified explaining 15.5% of the variance in the Walk-12G score. The factor with the strongest association with walking difficulties in daily life was cognitive perception speed (AQT part I) (explaining 4.9%) closed followed by anxiety (4.9%), cognitive perception speed (AQT part II) (3%) and frontal lobe/executive impairment (2.7%). Conclusion: Cognitive and psychiatric symptoms are associated with walking difficulties in persons with mild PD. Targeting cognitive perception speed, anxiety and frontal lobe/executive impairments in PD rehabilitation may help improve walking ability in daily life.

- Objective: To investigate fatigue at baseline and 3.5 years later and its association with balance and gait over time.Background: In Parkinson’s disease (PD), fatigue is considered one of the most common and disabling nonmotor symptoms that may persist or even worsen over time. Fatigue in generally has been described as a significantly diminished energy level or an increased perception of effort disproportionate to attempted activities. Fatigue has been associated to several nonmotor symptoms (e.g., depression, apathy, anxiety, sleep disturbances) and negatively impact quality of life in cross-sectional PD-studies. However, few studies have investigated fatigue over time and its association with other physical symptoms.Method: A prospective cohort of 70 persons with mild to moderate PD was assessed at baseline and 3.5 years later. Mean (SD) age and PD duration at baseline were 66 (8.9) and 4 (4.0) years, respectively and median (q1-q3) “on” phase motor symptoms (Unified PD Rating Scale, UPDRS, part III) were 11 (7-18). Fatigue was investigated with The Functional Assessment of Chronic Illness Therapy – Fatigue (FACIT-F, higher=better). Multiple linear regression analysis was performed with FACIT-F scores at baseline as dependent variable and a battery of clinical balance and gait tests targeting functional, reactive, and dynamic balance (Bergs Balance Scale vs Nutt Retropulsion Test vs Tandem gait, respectively), comfortable and fast gait speed and functional mobility (Timed up and go, TUG) as independent variables. The results were controlled for age and motor symptoms.Results: The median (q1-q3) FACIT-F scores at baseline (39 (30-36)) were significantly higher than corresponding value 3.5 years later (33.5 (22.5-41)). Significant association was found between FACIT-F scores at baseline and time needed to perform TUG 3.5 years later (B (95% CI); -0,568 (-0,925, -0.211), P=0.002)). These results suggest more than half a second longer time to perform the TUG for every point/score on the FACIT-F.Conclusion: Fatigue in people with PD seem to increase substantially over a relatively short time of 3.5 years. Fatigue also impacts functional mobility incorporating components of balance and gait ability in PD (gait speed, turning and sit-to-stand transfers). More longitudinal studies are needed to investigate long-term impact of fatigue on physical function in daily live.

- 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.

- The 3-step falls prediction model (3-step model) that include history of falls, history of freezing of gait and comfortable gait speed <1.1 m/s was suggested as a clinical fall prediction tool in Parkinson’s disease (PD). We aimed to externally validate this model as well as to explore the value of additional predictors in 138 individuals with relatively mild PD. We found the discriminative ability of the 3-step model in identifying fallers to be comparable to previously studies [area under curve (AUC), 0.74; 95 % CI 0.65–0.84] and to be better than that of single predictors (AUC, 0.61–0.69). Extended analyses generated a new model for prediction of falls and near falls (AUC, 0.82; 95 % CI 0.75–0.89) including history of near falls, retropulsion according to the Nutt Retropulsion test (NRT) and tandem gait (TG). This study confirms the value of the 3-step model as a clinical falls prediction tool in relatively mild PD and illustrates that it outperforms the use of single predictors. However, to improve future outcomes, further studies are needed to firmly establish a scoring system and risk categories based on this model. The influence of methodological aspects of data collection also needs to be scrutinized. A new model for prediction of falls and near falls, including history of near falls, TG and retropulsion (NRT) may be considered as an alternative to the 3-step model, but needs to be tested in additional samples before being recommended. Taken together, our observations provide important additions to the evidence base for clinical fall prediction in PD.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: This study aimed to comprehensibly investigate potential contributing factors to fear of falling (FOF) among people with idiopathic Parkinson's disease (PD). METHODS: The study included 104 people with PD. Mean (SD) age and PD-duration were 68 (9.4) and 5 (4.2) years, respectively, and the participants' PD-symptoms were relatively mild. FOF (the dependent variable) was investigated with the Swedish version of the Falls Efficacy Scale, i.e. FES(S). The first multiple linear regression model replicated a previous study and independent variables targeted: walking difficulties in daily life; freezing of gait; dyskinesia; fatigue; need of help in daily activities; age; PD-duration; history of falls/near falls and pain. Model II included also the following clinically assessed variables: motor symptoms, cognitive functions, gait speed, dual-task difficulties and functional balance performance as well as reactive postural responses. RESULTS: Both regression models showed that the strongest contributing factor to FOF was walking difficulties, i.e. explaining 60% and 64% of the variance in FOF-scores, respectively. Other significant independent variables in both models were needing help from others in daily activities and fatigue. Functional balance was the only clinical variable contributing additional significant information to model I, increasing the explained variance from 66% to 73%. CONCLUSIONS: The results imply that one should primarily target walking difficulties in daily life in order to reduce FOF in people mildly affected by PD. This finding applies even when considering a broad variety of aspects not previously considered in PD-studies targeting FOF. Functional balance performance, dependence in daily activities, and fatigue were also independently associated with FOF, but to a lesser extent. Longitudinal studies are warranted to gain an increased understanding of predictors of FOF in PD and who is at risk of developing a FOF.
