Postural & striatal deformities in Parkinson`s disease: Are these rare?

The implications of the foot health status in Parkinson patients: A case-control study

Parkinson's disease (PD) is a neurodegenerative disorder that affects both health of the feet, as to gait patterns. This study aimed to find out about foot problems and their impact on self-perceived quality of life and related to foot health in Parkinson's patients compared to a group of healthy subjects and to measure it with Spanish Podiatry Health Questionnaire (PHQ-S). It is about a case-control study in a sample of Parkinson's patients n = 62, healthy controls n = 62. The PHQ-S was reported, it describes perception the subject has in each of podiatric 6 dimensions consulted, assessing appreciation of health status of interviewee's feet and a self-rated the foot health score on the visual analog scale (VAS). There were statistically significant differences (P < 0.05) in the dimensions that assessed problems with walking and moving, nail trimming, concern feet state, and affectation of quality of life related foot health. Regarding the self-perception of state of their feet, Parkinson's patients perceive a worse state of health of their feet than healthy subjects. The mean value was 4.8 (SD 2.2) for Parkinson's patients and 3.8 (SD 2.3) for healthy subjects. In conclusion, patients with PD have problems in walking or moving, foot pain, difficulties in foot hygiene and in cutting for their nails, as well as the concern they suffer from deterioration in state of their feet affect them and decrease their quality of life. Podiatric problems in Parkinson's patients have a great impact in reducing quality of life related to foot health.

Effect of Foot Orthoses and Shoes in Parkinson's Disease Patients: A PRISMA Systematic Review

Reduced plantar foot sensation, postural instability, and gait difficulties are characteristic of Parkinson´s disease patients. A systematic review was carried out to determine the effect of the different types of insoles and shoes in these patients. Several databases were used to search for relevant articles reporting Parkinson´s disease patients undergoing treatment with any type of insole and footwear. All titles and abstracts were reviewed independently by two reviewers and the available data were extracted. The study eligibility criteria were any type of experimental study that included Parkinson’s disease patients treated with any type of insole or footwear. Eight studies were selected. Interventions used were textured insoles, footwear modifications, and habitual footwear. Three different outcomes were evaluated in each study: gait parameters, balance, and plantar sensation. According to the data available from this systematic review, the most important conclusion is that more controlled studies are needed in this research field. There are indications to suggest that textured insoles have positive effects on gait parameters, balance, and plantar sensation in Parkinson’s disease patients.

NPT520-34 improves neuropathology and motor deficits in a transgenic mouse model of Parkinson's disease

NPT520-34 is a clinical-stage, small molecule being developed for the treatment of Parkinson's disease and other neurodegenerative disorders. The therapeutic potential of NPT520-34 was first suggested by findings from cell-based assays of alpha-synuclein (ASYN) clearance. As reported here, NPT520-34 was subsequently evaluated for therapeutically relevant actions in a transgenic animal model of Parkinson's disease that overexpresses human ASYN and in an acute lipopolysaccharide (LPS)-challenge model using wild-type mice. Daily administration of NPT520-34 to mThy1-ASYN (Line 61) transgenic mice for one or three months resulted in reduced ASYN pathology, reduced expression of markers of neuroinflammation, and improvements in multiple indices of motor function. In an LPS-challenge model using wild-type mice, a single-dose of NPT520-34 reduced LPS-evoked increases in the expression of several pro-inflammatory cytokines in plasma. These findings demonstrate the beneficial effects of NPT520-34 on both inflammation and protein-pathology endpoints, with consequent improvements in motor function in an animal model of Parkinson's disease. These findings further suggest that NPT520-34 may have two complementary actions: (1) to increase the clearance of neurotoxic protein aggregates and (2) to directly attenuate inflammation. NPT520-34 treatment may thereby address two of the predominate underlying pathophysiological aspects of neurodegenerative disorders such as Parkinson's disease.

Pramipexole-induced limb dystonia and its associated complex regional pain syndrome in idiopathic Parkinson's disease: A case report

RATIONALE

This case may be due to basal ganglia dysfunction, which was probably caused by abnormal activation of dopamine 1-like receptor (D1R) boosted by pramipexole binding on dopamine 3-like receptor (D3R) in a situation where D3R was overexpressed by the chronic treatment of L-dopa.

PATIENT CONCERNS

Striatal hand and foot deformities.

DIAGNOSES

Striatal hand and foot deformities with CRPS.

INTERVENTIONS

Steroid treatemnt and withdrawal of the pramipexole.

OUTCOMES

Recovered significantly.

LESSONS

Since the degree of overexpression of D3R is increased in a high dose of pramipexole, for patients with PD who are treated with L-dopa chronically, a new use of pramipexole and an increase in dose to alleviate the symptoms of PD should be implemented with caution while closely observing the occurrence of drug-induced complications such as dystonia and CRPS.

Body Posture, Postural Stability, and Metabolic Age in Patients with Parkinson's Disease

BACKGROUND

The study aims to analyze the relationship between body posture and composition, as well as postural stability in Parkinson's disease patients.

MATERIAL AND METHODS

32 people were evaluated. The study was conducted in the Laboratory of Posturology at Jan Kochanowski University in Kielce (Poland). Body posture was examined using the optoelectronic body posture Formetric Diers Method III 4D. Postural stability was evaluated using the Biodex Balance System platform. Body composition was assessed with the method of bioelectrical impedance analysis using the Tanita MC 780 MA analyzer.

RESULTS

11 patients (34.37%) had hyperkyphosis, 10 (31.25%) hyperlordosis, and 3 (9.37%) hyperkyphosis-hyperlordosis posture. Scoliosis (>10°) was observed in 28 (87.5%) subjects, whereas 4 (12.5%) presented scoliotic body posture (1-9°). In the examined population, all parameters of postural stability were within normal limits.

CONCLUSIONS

A significant positive correlation was observed between surface rotation (°), General Stability Index (r = 0.4075, p = 0.0206), and Anteroposterior Stability Index (r = 0.3819, p = 0.0310). There was also a significant positive correlation between surface rotation (+max) (°), General Stability Index (r = 0.3526, p = 0.0206), and Anteroposterior Stability Index (r = 0.3873, p = 0.0285). Metabolic age also presented a significant positive correlation between metabolic age and General Stability Index (r = 0.4057, p = 0.0212), as well as Anteroposterior Stability Index (r = 0.3507, p = 0.0490).
