[en] Introduction. Parkinson's disease is one of the most common neurological disorders in the world. It is characterized by the triad made up of tremor, rigidity and bradykinesia, which together with other manifestations cause movement disorders such as slowness to initiate and execute voluntary movements, festive gait, gait blocks and loss of balance. There is evidence that Nordic walking and rhythmic auditory stimulation cause a positive effect on the spatiotemporal parameters of gait in these types of patients, but which of them provides the greatest benefit to date has not been studied. Objective. The objective of this study is to analyze whether there are statistically significant differences in the spatiotemporal parameters of gait in Parkinson's patients, depending on whether the treatment is based on Nordic walking or on rhythmic auditory stimulation. Methodology. To resolve this question, a single-blind randomized clinical trial was proposed with direct users of the Parkinson's Association of A Coruña with a stage II-III according to the Hoehn and Yahr scale. These patients will be divided into three groups: one focused on Nordic walking, another on rhythmic auditory stimulation, and another will be formed by the control group. The program will last a total of 48 weeks, of which 12 will be dedicated to the intervention part that will consist of 3 weekly sessions where the duration will depend on the chosen treatment. The gait variables will be analyzed in relation to stride and stride length, stride width, gait time, cadence and perceived effort, in addition to the variable related to quality of life.

[gl] Introdución. A enfermidade de Parkinson é un dos trastornos neurolóxicos máis comúns en todo o mundo. Caracterízase pola triada composta de tremor, rixidez e bradicinesia, que causan xunto a outras manifestacións, trastornos no movemento como lentitude para iniciar e executar movementos voluntarios, marcha festinante, bloqueos da marcha e perda do equilibrio. Existe evidencia de que tanto a marcha nórdica como a estimulación auditiva rítmica causan un efecto positivo nos parámetros espaciotemporais da marcha neste tipo de pacientes, pero non foi estudado cal deles achega un maior beneficio ata o momento. Obxectivos. O obxectivo deste estudo é analizar se existen diferenzas estatisticamente significativas nos parámetros espaciotemporais de marcha en pacientes de Parkinson dependendo de se o tratamento baséase en marcha nórdica ou en estimulación auditiva rítmica. Metodoloxía. Para resolver esta cuestión exponse un ensaio clínico aleatorizado simple cego cos usuarios directos da Asociación de Parkinson da Coruña cun estadio II- III segundo a escala de Hoehn e Yahr. Estes pacientes dividiranse en tres grupos: un centrado en marcha nórdica, outro en estimulación auditiva rítmica e outro será o formado polo grupo control. O programa durará un total de 48 semanas, das cales 12 irán dedicadas á parte de intervención que constará de 3 sesións semanais onde o tempo de duración dependerá do tratamento elixido. Analizaranse as variables da marcha en relación coa lonxitude de paso e zancada, anchura de paso, tempo de marcha, cadencia e esforzo percibido, ademais da variable relacionada coa calidade de vida.
