Detailed testing plan.

Phase ID	Purpose	Activities	Performance Measurements	Duration
Phase 0	System presentation and accommodation	- Informed consent - Initial health parameters measured (heart rate, blood pressure) - System presentation (hardware and software) - VR accommodation (if applicable) - User muscular profile calibrated on the Myo gesture control armband - VR system configuration according to the user’s data (if applicable)	- User feedback	One hour
Phase 1	Classical training exercises for both upper and lower limb Goniometer and system’s recorded values comparison	- Fitness bracelet exercising mode started - Upper limb exercises, 5 repetitions/trials with each limb at a time and 5 repetitions with both at the same time: Shoulder: flexion 0°–90°, abduction 0°–90°; Elbow: forearm flexion, supination; Fist: arm pushing, extension. - Lower limb exercises, 5 repetitions/trials with each limb at a time: Hip: flexion, abduction; Knee: flexion; Ankle: flexion.	- Joint angles (system) for each individual trial - Goniometer angle for first trial - System accuracy—per exercise, per patient, overall - Average joint angle for right/left limb across all 5 trials - Mobility degree (according to mobility classes established in Appendix A) - Average execution times for each exercise	One hour
Phase 2	Gamified training	- Presentation of input for performing in-game actions and accommodation time (a few minutes) for each game - Hit targets: 3 min adaptively, from easy and gradually increasing difficulty levels (medium, difficult) - Ball directing: 3 trials of one minute each, the user must beat their previous record - Whack-a-mole: 3 trials of one minute each with different levels of difficulty (easy, medium, difficult) - Boxing—3 trials of one minute each in different settings (2 in the ring—easy, 1 with the punching bag—medium) - Football—3 trials with 12 shots each (2 from penalty distance, 1 from free kick distance)	- Score according to each game’s logic - Performance classes of each game (according to the classes established in Annex 2) - Hit targets: maximum difficult reached, number of cans hit in each hit, number of tries to complete a level - Ball directing game: number of holes hit - Whack-a-mole: number of moles hit, maximum number of moles that could have been hit, accuracy - Boxing: number of hits with right and left fist; applied force - Football: number of goals, accuracy	30–45 min
Phase 3	Final feedback	- Feedback collected related to topics such as: Opinion on exercises, scenes, graphics VR perception (negative effects, discomfort, embodiment) Suggestions for improvement	- User feedback	15–20 min
