Comparative Effects of Virtual Reality and Proprioceptive Neuromuscular Facilitation in Patients With Parkinson's Disease

Primary outcomes

1. Kinetic Tremors

   Time frame: 6 weeks

   Kinetic Tremors It is going to be measured by: Fahn-Tolosa-Marin tremor rating scale with internal consistency of Cronbach's α = 0.90.

   FTMTRS - Kinetic Tremor Section

   Rate the severity of tremor during each task using the following scale:

   • Writing: _______
   • Drawing (Archimedes spiral): _______
   • Pouring water: _______
   • Drinking from a cup: _______ • Total Kinetic Tremor Score: _______/16 (0 = No tremor, 1 = Mild, intermittent, 2 = Moderate, intermittent or mild, continuous, 3 = Marked, intermittent or moderate, continuous, 4 = Severe, continuous)

2. Bradykinesia

   Time frame: 6 weeks

   It is going to be measured by: MDS-UPDRS Part III with internal consistency of Cronbach's α: 0.90-0.93.

   MDS-UPDRS Part III - Bradykinesia Items (3.4-3.6)

   Rate each movement on a scale from 0 (normal) to 4 (severe):

   • 3.4 L&R Finger Tapping: _______
   • 3.5 L&R Hand Movements (open/close hands): _______
   • 3.6 L&R Pronation-Supination of Hands: _______ • Total Bradykinesia Score (3.4-3.6): _______/24

3. Proprioception

   Time frame: 6 weeks

   •It is going to be measured by: Fugl Meyer UE Proprioception subscale with internal consistency of Cronbach's α: at 0.94-0.98.

   Scoring:

   0 = Only a few degrees (less than 10° in shoulder)

   • = Decreased
   • = Normal
