Feasibility of a Community-Based Multimodal Exercise Programme in Parkinson's Disease

Eligibility Criteria The eligibility criteria will be identical for both the experimental and control groups. However, this study will employ a sequential recruitment design. Participants for the control group will be recruited following the experimental group and will be matched (1:1 ratio) based on sex, age (± 5 years), and disease severity according to the Hoehn \& Yahr (H\&Y) scale.

Inclusion Criteria:

* Subjects diagnosed with Idiopathic Parkinson's Disease according to the UK Parkinson's Disease Society Brain Bank Diagnostic Criteria.
* Subjects staged between 1 and 3 on the Hoehn \& Yahr Scale. For matching purposes, stage 1 includes stage 1.5, and stage 2 includes stage 2.5.

Exclusion Criteria:

* Subjects diagnosed with a neurological disease other than PD.
* Those diagnosed with a cardiovascular, respiratory, or metabolic disease or other conditions that represent a contraindication to physical exercise.
* Those who have suffered an exacerbation or hospitalization in the last three months prior to starting the assessment protocol or during the therapeutic intervention process.
* Those who have received a course of steroids, intravenously or orally, six months prior to the start of the study or during the therapeutic intervention process.
* Those with cognitive impairment (defined as a score \< 21 on the Montreal Cognitive Assessment, MoCA) or language impairments that prevent adequate communication, comprehension, or following of exercise instructions.
* Participation in a structured, individualized strength and/or aerobic exercise program within the three months prior to enrollment.
