Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in motor function as assessed by the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Total Score	The MDS-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) is a widely used research tool to quantify the clinical characteristics of PD in adults. This scale assesses various aspects of Parkinson's disease, including motor and non-motor experiences of daily life and motor complications. This test will take approximately 30 minutes, assessing the impact of the disease in 4 different domains distributed in 65 items, of which 48 are scored from 0 to 4 and seven with dichotomous answers of "yes" or "no". The global range of the MDS-UPDRS will be from 0 to 260 points, the higher the score, the greater the disease involvement.	Day 0, 1 Month, 3 Months, 6 Months, 12 Months
Primary	Quality of life as assessed by the 39-item Parkinson's disease Questionnaire (PDQ-39)	The 39-item Parkinson's disease Questionnaire (PDQ-39) is the most widely test used to assess specific quality of life questionnaire for Parkinson's disease, and it has been validated and cross-culturally translated. The questionnaire consists of 39 questions to be completed by the patient, that assesses the frequency in which patients with PD experience difficulties in 8 dimensions of functionality and well-being: mobility, activities of daily living, emotional well- being, attention and memory, social support, depression, cognition, communication and social relationships. Items can be transformed on a linear scale from 0 to 100, the higher the score reflects a lower quality of life.	Day 0, 1 Month, 3 Months, 6 Months, 12 Months
Primary	Speech voice sound and duration	Since most people with Parkinson's disease (PD) have voice and speech disorders that result in harmful effects on communication and quality of life; the measurement of the pressure level and sound duration will be executed using the Samson Go Mic and the software used for the Lee Silverman Voice Treatment Therapy (LSVT LOUD).	Day 0, 1 Month, 3 Months, 6 Months, 12 Months
Primary	Dynamic balance and movement during translational motion and single-limb stance in seconds as assessed by the Mini Balance Evaluation Systems Test (mini BESTest)	The Mini Balance Evaluation Systems Test (mini BESTest) has proven to be a reliable and valid measurement tool for patients with PD. It is aimed to measure dynamic balance and associated movement during translational motion. The test consists of 14 items, with a maximum score of 28 points, with a higher test result, the greater the patient's functionality 35 . The test has high inter-rater reliability (ICC = 0.92) and high test-retest reliability (ICC = 0.92) for PD patients.	Day 0, 1 Month, 3 Months, 6 Months, 12 Months
Primary	Balance as assessed by the The Five-times Sit-to-stand Test	The Five-times sit-to-stand Test is a tool that quantifies the ability of patients suffering from diseases associated with balance problems, as in the case of PD, to perform transitional motions. In addition, it has been used as a measure of lower limb strength. The test has excellent inter-rater reliability and high test-retest reliability, as well as assessing for the risk of falls in patients with PD.	Day 0, 1 Month, 3 Months, 6 Months, 12 Months
Primary	Mobility and fall risk as assessed by the Timed "Up & Go" test	The Timed "Up & Go" test consists of observing and timing the patient as he gets up from an armchair, walking for 3 meters, turns, returns and sits down again. The results of this test correlates well with the logarithmic transformation scores on the Berg Balance Scale, gait speed and the Barthel Index of AVD (Activities of Daily Living), and can predict the patient's ability to walk alone safely.	Day 0, 1 Month, 3 Months, 6 Months, 12 Months
Primary	Balance and postural stability as assessed by the Clinical test of Sensory Interaction & Balance Test (CTSIB), stability limits, and unipodal balance test	Computerized posturography using a force platform system provides objective and quantitative evaluations of deficiencies in postural control. The participants of the present study will be subjected to two tests of balance and postural stability using the HUMAC®43 brand force platform system. Three tests will be performed: CTSIB test (Clinical test of Sensory Interaction & Balance), the stability limits, and the unipodal balance test.	Day 0, 1 Month, 3 Months, 6 Months, 12 Months
Primary	Tremor and handwriting	Alterations in the kinematics of handwriting are among the recently proposed biomarkers of PD. Recent studies have suggested the potential of handwriting analysis for both early diagnosis and assessment of disease progression. In the present study, the patients will be subjected to 5 tests, at 5 different times of the study using the MovAlyzeR® software in conjunction with the WACOM ONE tablet, to measure the speed, amplitude, fluidity and tremor of the movements of the upper extremities.	Day 0, 1 Month, 3 Months, 6 Months, 12 Months
Primary	Grip strength	The decrease in grip strength is a predictor of adverse outcomes in older adults and will be determined using a Jamar brand digital dynamometer to measure the grip strength of the patients participating in each assessment.	Day 0, 1 Month, 3 Months, 6 Months, 12 Months
Primary	Dynamic balance in the bipedal as measured by the 360 degree turn test	This test measures dynamic balance in the bipedal. In this test, the number of steps and the time that take the patient to make a complete 360-degree turn will be measured.	Day 0, 1 Month, 3 Months, 6 Months, 12 Months
Secondary	Adverse events upon clinical examination	Study participants will be examined for clinical signs of adverse events.	Day 0, 1 Month, 3 Months, 6 Months, 12 Months
Secondary	Optimal number of doses of 2.5 x 10^7 PASCs for therapeutic response	The optimal number of doses of PASCs for therapeutic response will be measured.	Day 0, 1 Month, 3 Months, 6 Months, 12 Months
