The Impact

We investigated the impact of Nordic walking (NW) on gait patterns in individuals with Parkinson’s disease (PD) following a 6-week NW familiarization. Twelve participants with PD and 12 healthy older adults took part in a gait analysis walking with and without poles (NP). Results showed larger knee power (knee extensor: K2) on the most affected leg in NW compared to NP (P = .01). On the less affected side, larger power absorption (knee extensor: K3) was found during preswing (K3) compared to older adults in both NP and NW (P = 0.01). NW showed longer stride length and single support time (P < .01) compared to NP. Walking with poles improved gait spatial–temporal characteristics and power profiles at the knee joint both on the less and most affected sides in individuals with PD. NW could be beneficial to help regain a more functional gait pattern in PD.

The Impact

This study examined how future self-representations are affected by two different chronic illnesses, one focused on cognitive losses, early-stage Alzheimer's disease (AD), and one focused on physical losses, Parkinson's disease (PD). The impact of illness on possible selves (perceptions of self in the future) was made salient by a comparison with healthy older adults in order to better understand developmental issues in later life. Findings show that although there were no differences in the total number of domains reported by the groups, specific domains were reported differently by patient groups and all domains were likely to become infused with illness. As expected, patient groups had less self-efficacy and lower outcome expectancies for their future selves, and PD patients reported less distance from their feared selves. Although these findings are intuitive, this is the first empirical effort to document the impact of illness on older adults' self-representations. Group differences are explained in terms of disease context, and the importance of possible selves and self-regulatory functions as therapeutic mechanisms for adaptation to illness are emphasised.

Background: An external cue can markedly improve gait initiation in people with Parkinson’s disease (PD) and is often used to overcome freezing of gait (FOG). It is unknown if the effects of external cueing are comparable if the imperative stimulus is triggered by the person receiving the cue (self-triggered) or an external source. Objective: Two experiments were conducted to compare the effects of self- versus externally triggered cueing on anticipatory postural adjustments (APAs) during gait initiation in people with PD. Methods: In experiment 1, 10 individuals with PD and FOG initiated gait without a cue or in response to a stimulus triggered by the experimenter or by the participant. Experiment 2 compared self- versus externally triggered cueing across three groups: healthy young adults (n = 16), healthy older adults (n = 11), and a group with PD (n = 10). Results: Experiment 1: Externally triggered cues significantly increased APA magnitudes compared to uncued stepping, but not when the same cue was self-triggered. Experiment 2: APAs were not significantly improved with a self-triggered cue compared to un-cued stepping in both the PD and healthy older adult groups, but the young adults showed a significant facilitation of APA magnitude. Conclusion: The effectiveness of an external cue on gait initiation in people with PD and older adults is critically dependent upon whether the source of the trigger is endogenous (self-produced) or exogenous (externally generated). These results may explain why cueing interventions that rely upon self-triggering of the stimulus are often ineffective in people with PD.

Conflicting Evidence

ABSTRACTRationaleParkinson’s disease (PD) impairs working memory (WM) - the ability to maintain items in memory for short periods of time and manipulate them. There is conflicting evidence on the nature of the deficits caused by the disease, and the potential beneficial and detrimental effects of dopaminergic medication on different WM processes.ObjectivesWe hypothesised that PD impairs both maintenance and manipulation of items in WM and dopaminergic medications improve this in PD patients but impair it in healthy older adults.MethodsWe tested 68 PD patients ON and OFF their dopaminergic medication, 83 healthy age-matched controls, and 30 healthy older adults after placebo and levodopa administration. We used the digit span, a WM test with three components (forwards, backwards and sequence recall) that differ in the amount of manipulation required. We analysed the maximum spans and the percentage of lists correctly recalled, which probe capacity of WM and the accuracy of the memory processes within this capacity, respectively.ResultsPD patients had lower WM capacity across all three digit span components, but only showed reduced percentage accuracy on the components requiring manipulation (backwards and sequence spans). Dopaminergic medication did not affect performance in PD patients. In healthy older adults, levodopa did not affect capacity, but did impair accuracy on one of the manipulation components (sequence), without affecting the other (backwards).ConclusionsThis suggests a non-dopaminergic deficit of maintenance capacity and manipulation accuracy in PD patients, and a potential “overdosing” of intact manipulation mechanisms in healthy older adults by levodopa.

The Impact

Abstract Background impairments in neurotransmitter pathways put Parkinson’s disease (PD) patients at risk for drug–disease interactions and adverse medication events. Objective to determine the prevalence and risk factors for potentially inappropriate medication (PIM) prescriptions, as defined by the 2015 Beers List, in PD. Methods cross-sectional analysis was conducted on 2014 Medicare beneficiaries with PD who had parts A, B and D coverage. The prevalence of PIM prescriptions for older adults was determined overall, and specifically for medications that can exacerbate motor symptoms or cognitive impairment in PD. Logistic regression models were constructed to determine the association between age, sex, race, geography and poverty with PIM prescriptions. Results the final sample included 458,086 beneficiaries. In 2014, 35.8% of beneficiaries with PD filled a prescription for at least one PIM for older adults. In total, 8.7% of beneficiaries received a PIM that could exacerbate motor symptoms and 29.0% received a PIM that could worsen cognitive impairment. After adjustment, in all models, beneficiaries who were younger, female, white, urban-dwelling and eligible for Medicaid benefits were more likely to receive a PIM. Conclusion PIM prescriptions are not uncommon in PD, particularly for medications that can exacerbate cognitive impairment. Future research will examine underlying drivers of sex and other disparities in PIM prescribing. Additional studies are needed to understand the impact of PIMs on disease symptoms, healthcare utilisation and patient outcomes.

Before And After

AbstractPlantar cutaneous stimulation has been shown to improve gait in Parkinson's disease (PD), but the effects of different types of insoles have not been tested. We evaluated the immediate effect of different types of insoles on gait in PD patients and healthy older adults. Nineteen PD patients and nineteen healthy older adults performed and performed a walking task at their self-selected speed in three conditions: conventional insole, insole with a raised ridge around the foot perimeter, and insole with half-spheres. Plantar sensation was evaluated before and after the walking protocol. There were no differences between groups for plantar sensation before and after the walking task. PD patients demonstrated reduced stride length and stride velocity. There were no immediate benefits offered by the insoles on gait of either group. The increased plantar cutaneous stimulation does not promote immediate benefits on gait in PD patients and healthy older adults.
