Habilidades motoras y de procesamiento en personas con enfermedad de Parkinson en comparación con adultos mayores sanos. Un estudio transversal / Motor and process skills of people with parkinson’s disease compared to healthy older adults. A cross-sectional study

Introducción Tanto la enfermedad de Parkinson (EP) como el proceso de envejecimiento están asociados con limitaciones funcionales. El objetivo de este estudio fue determinar las diferencias en habilidades motoras y de procesamiento entre individuos con EP y adultos mayores sanos, así como observar cómo la progresión de la enfermedad afecta al desempeño de las habilidades motoras y de procesamiento en pacientes con EP. Sujetos y métodos Se realizó un estudio transversal. Se empleó la medida de la Assessment of Motor and Process Skills (AMPS) para analizar las diferencias en las habilidades motoras y de procesamiento de tareas cotidianas entre personas con EP y adultos mayores sanos, emparejados en edad y sexo. Se administró la sección III de la Unified Parkinson Disease Rating Scale, la escala de Hoehn y Yahr (HY) y la escala de Schwab & England para determinar la gravedad de la enfermedad. Resultados Se reclutó a 70 participantes (49 pacientes con EP y 21 adultos mayores sanos). Nuestros resultados mostraron que incluso en estadios moderados de la enfermedad, tanto las habilidades motoras como las de procesamiento se encontraron deterioradas en los pacientes con EP en comparación con los adultos mayores sanos (p < 0,001). A medida que avanza la enfermedad, las habilidades motoras y de procesamiento presentan un deterioro significativo en las personas con EP. Conclusiones La EP conduce a un mayor deterioro de las habilidades motoras y de procesamiento en comparación con adultos mayores sanos. A medida que avanzan los estadios de la enfermedad según la escala HY, el rendimiento en las habilidades motoras y de procesamiento se deteriora significativamente entre los estadios moderados y avanzados de la EP. Según la escala AMPS, los pacientes con EP no muestran un deterioro en las habilidades de procesamiento hasta el estadio HY IV, pero muestran deterioro motor en los estadios HY II, III y IV. (AU)

INTRODUCTION Both Parkinson’s disease (PD) and the process of ageing are associated with functional limitations. The aim of this study was to determine the differences in motor and process skills between individuals with PD and healthy older adults, as well as to observe how disease progression affects motor and process skills performance in PD patients. SUBJECTS AND METHODS A cross-sectional study was conducted. The Assessment of Motor and Process Skills (AMPS) measure was employed in order to analyze the differences in the motor and process skills of daily tasks in people with PD and healthy older adults age- and sex-matched. Part III of the Unified Parkinson Disease Rating Scale (UPDRS), the Hoehn and Yahr (HY) scale and the Schwab & England scale was administered to determine the severity of the disease. RESULTS Seventy participants (49 patients with PD and 21 healthy older adults) were recruited for this study. Our results showed that even at moderate stages of the disease, both motor and process skills were found deteriorated in PD patients more than older healthy older adults (p < 0.001). As PD progresses, motor and process skills present significantly deterioration. CONCLUSION. PD leads to a greater deterioration in motor and process skills compared to healthy older adults. As disease stages advance according to the HY scale, performance in motor and process skills deteriorates significantly between moderate and advanced PD stages. According to the AMPS scale, PD patients show no impairment of processing skills up to HY IV, but motor impairment at HY stages II, III and IV.

Trunk Range of Motion Is Related to Axial Rigidity, Functional Mobility and Quality of Life in Parkinson's Disease: An Exploratory Study.

BACKGROUND: People with Parkinson's disease (PD) present deficits of the active range of motion (ROM), prominently in their trunk. However, if these deficits are associated with axial rigidity, the functional mobility or health related quality of life (HRQoL), remains unknown. The aim of this paper is to study the relationship between axial ROM and axial rigidity, the functional mobility and HRQoL in patients with mild to moderate PD. METHODS: An exploratory study was conducted. Non-probabilistic sampling of consecutive cases was used. Active trunk ROM was assessed by a universal goniometer. A Biodex System isokinetic dynamometer was used to measure the rigidity of the trunk. Functional mobility was determined by the Get Up and Go (GUG) test, and HRQoL was assessed with the PDQ-39 and EuroQol-5D questionnaires. RESULTS: Thirty-six mild to moderate patients with PD were evaluated. Significant correlations were observed between trunk extensors rigidity and trunk flexion and extension ROM. Significant correlations were observed between trunk flexion, extension and rotation ROM and GUG. Moreover, significant correlations were observed between trunk ROM for flexion, extension and rotations (both sides) and PDQ-39 total score. However, these correlations were considered poor. CONCLUSIONS: Trunk ROM for flexion and extension movements, measured by a universal goniometer, were correlated with axial extensors rigidity, evaluated by a technological device at 30°/s and 45°/s, and functional mobility. Moreover, trunk ROM for trunk flexion, extension and rotations were correlated with HRQoL in patients with mild to moderate PD.

Axial rigidity is related to the risk of falls in patients with Parkinson's disease.

BACKGROUND: Rigidity is a cardinal symptom of Parkinson's disease (PD) and is often clinically assessed by passively flexing and extending a patient's limb. Objective measurements had been employed to examine rigidity in PD subjects, including wrist, elbow or knee. OBJECTIVE: This study aimed to investigate the relationship between an objective measurement of trunk rigidity and risk of falls in patients with mild to moderate PD. METHODS: An isokinetic dynamometer Biodex System 3 was employed to assess trunk rigidity in 36 patients with mild to moderate PD at a University Department in a cross-sectional study. Risk of falls was measured by the Get Up & Go test (GU&G). Disease severity (Hoehn and Yahr staging score and the Unified Parkinson's Disease Rating Scale III), disease duration and functional status (Schwab & England activities of daily living scale) were also evaluated. RESULTS: Significant correlations between trunk extensors rigidity at 45°/s and 60°/s and risk of falls were obtained. A correlation between trunk extensors tone at 30°/s and the GU&G test almost reached significant almost reached statistical significance (r = 0.306; p = 0,066). Significant correlations between trunk flexors-extensors tone and clinical status, disease duration and functional status at 30°/s, 45°/s and 60°/s were also obtained. CONCLUSION: The results from this study suggest that the axial rigidity is related to the risk of falls in patients with mild to moderate PD. Further studies are needed with quantitative devices for axial rigidity assessment to determine the relationship between trunk rigidity in PD patients with higher disease severity and risk of falls.

Isokinetic dynamometry as a technologic assessment tool for trunk rigidity in Parkinson's disease patients.

BACKGROUND: Rigidity is a cardinal symptom of Parkinson's disease (PD). There are few studies that have assessed rigidity with objective tools in PD patients. OBJECTIVE: This study aimed to develop an objective measurement to quantify trunk rigidity in PD patients with a technology device and to investigate the relationship between this objective assessment and to examine its relationship with disease severity (Hoehn and Yahr staging score and the Unified Parkinson's Disease Rating Scale III) disease duration, functional status (Schwab & England activities of daily living scale) and health related quality of life (European Quality of Life-5 Dimensions and Parkinson's Disease Questionnaire-39 items) in patients with mild to moderate PD. METHODS: An isokinetic dynamometer Biodex System 3 was employed to assess trunk rigidity in 36 PD patients. Passive trunk flexion and extension at 3 angular velocities, 30°/s, 45°/s and 60°/s were applied and resistive torques were recorded as trunk flexor and extensors rigidity. RESULTS: Significant correlations between trunk flexors-extensors tone and clinical status, disease duration and functional status at 30°/s, 45°/s and 60°/s were obtained. No correlations were found among trunk muscle tone assessed with the isokinetic dynamometer and the EuroQoL-5D. Trunk rigidity was correlated with the HRQoL assessed with the mobility, cognition and stigma PDQ-39 domains and the total PDQ-39 scores. CONCLUSION: Our results suggest that the 30°/s, 45°/s and 60°/s angular velocities of this objective technology method were a valid assessment for trunk rigidity and were correlated with disease severity, disease duration, functional status and HRQoL in PD patients.

Thermal and mechanical pain thresholds in patients with fluctuating Parkinson's disease.

Study results evaluating pain thresholds in patients with Parkinson's disease (PD) vary widely. Thus, we designed our study to determine the effects of levodopa on the thresholds of pressure (PPT), heat (HPT) and cold pain (CPT) in PD patients with motor fluctuations (18 patients: 10 men, 8 women; age: 65 ± 10 years; mean disease duration: 11.6 ± 6 years), six of whom (33%) reported pain related to their disease. We compared these thresholds in patients in the ON and OFF states with those in 18 age- and sex-matched controls. Pain thresholds were assessed over: the frontal bones, C5-C6 zygapophyseal joints and second metacarpals (PPT); the dorsal aspect of the hand (HPT and CPT); and the tibialis anterior (TA) muscles. PD patients in the OFF state had lower PPT thresholds at all sites (P < 0.001) than healthy controls. Moreover, HPT and CPT thresholds were lower at all sites except over the TA muscle (P < 0.01). In the ON state, the PPT and CPT thresholds in PD patients were lower than in controls at all points, except over the TA (CPT) and the second metacarpals (PPT) P < 0.01. Pain thresholds were no different in PD patients in the ON or OFF state (P > 0.10), and the existence of pain did not influence the results. We detected mechanical and thermal pain hypersensitivity in PD patients in the OFF state, and levodopa administration did not increase these thresholds. Thus, while dopamine may modulate pain responses, other mechanisms are likely to be implicated in the modulation of these pain responses in PD patients.

Axial rigidity and quality of life in patients with Parkinson's disease: a preliminary study.

PURPOSE: Rigidity is a cardinal symptom of Parkinson's disease (PD) and is often clinically assessed by passively flexing and extending a patient's limb. Objective measurements had been employed to examine rigidity in PD subjects, including wrist, elbow, knee and trunk. This study aimed to investigate the relationship between an objective measurement of trunk rigidity and health-related quality of life (HRQoL) and functional status in patients with mild to moderate PD. METHODS: An isokinetic dynamometer Biodex System 3 was employed to assess trunk rigidity in 36 PD patients. HRQoL was assessed with the EuroQol-5D and Parkinson's Disease Questionnaire-39 items (PDQ-39). Functional status was measured with the Schwab and England scale. RESULTS: Trunk rigidity was correlated with the HRQoL assessed with the mobility, cognition and stigma PDQ-39 domains and the total PDQ-39 scores. No correlations were found among trunk muscle tone assessed with the isokinetic dynamometer and the EuroQoL-5D. Functional status was correlated with the trunk extensors rigidity at all angular velocities. CONCLUSION: The results from this study suggest that the axial motor impairments impact on QoL and functional status in patients with PD. Further studies are needed with quantitative devices for axial rigidity assessment to determine the relationship between trunk rigidity in PD patients with higher disease severity and HRQoL scales.

[Health-related quality of life in Parkinson's disease]. / Calidad de vida relacionada con la salud en la enfermedad de Parkinson.

Parkinson's disease is a disabling and progressive neurological condition characterized by multiple motor and non motor symptoms that contribute to deterioration in quality of life. The diversity of symptoms associated with the disease and its management affect the patients on their physical, social and mental quality of life. The aim of this study was to identify key dimensions of health related quality of life (HRQOL) in a population affected with Parkinson's disease with a degree of mild-moderate impairment. Thirty six patients with Parkinson were recruited. The Hoehn and Yarh scale, the Unified Parkinson's Disease Rate Scale, the scale of activities of daily life and Schwab & England Get Up & Go Test were applied. HRQOL was assessed with the EuroQol-5D and the specific questionnaire Parkinson's Disease Questionnaire-39 items. The dimensions of the PDQ-39, except the PDQ-39 Pain domain and the EuroQol-5D correlated significantly with the severity of the disease. HRQOL was correlated with the functional status of patients. Only the PDQ-39 pain domain correlated with the risk of falls. Our results suggest that the HRQOL of patients with PD, in a state of mild-moderate impairment, is strongly influenced by disease severity and functional status.

Calidad de vida relacionada con la salud en la enfermedad de Parkinson / Health-related quality of life in Parkinson's disease

La enfermedad de Parkinson (EP) es un trastorno neurológico, discapacitante y progresivo caracterizado por múltiples síntomas motores y no motores que contribuyen al deterioro en la calidad de vida del paciente. La diversidad de síntomas asociados a la enfermedad y su manejo afectan a la funcionalidad y las expectativas del individuo sobre su bienestar físico, social y mental, que son los componentes fundamentales de la calidad de vida relacionada con la salud (CVRS). El objetivo del presente trabajo fue identificar las principales dimensiones de la CVRS afectadas en una población con EP con un grado de afectación leve-moderado. Treinta y seis pacientes con EP completaron este estudio transversal. Se emplearon el estadio de Hoehn y Yarh, el Unified Parkinson's Disease Rate Scale, la escala de actividades de la vida diaria de Schwab y England y el Test Get Up & Go. La calidad de vida fue valorada con el EuroQoL-5D y con el cuestionario Parkinson's Disease Questionnaire-39 items. Las dimensiones del PDQ-39, excepto el dominio PDQ-39 Dolor, así como el cuestionario EuroQoL-5D se correlacionaron de manera significativa con la gravedad de la enfermedad. La CVRS se correlacionó con el estado funcional de los pacientes. Únicamente el dominio PDQ-39 Dolor se correlacionó con el riesgo de caídas. Nuestros resultados sugieren que la CVRS de los pacientes con EP, en un estado leve-moderado de afectación, está muy influenciada por la gravedad de la enfermedad y el estado funcional.
