Usability of the FTEXES Wearable Textile Platform for Functional Electrical Stimulation and EMG (FTEXES)
Interventional Clinical Trial Evaluating the Usability of the FTEXES System (Functionalized TEXtiles for Electrical Stimulation), a Wearable Textile-Based Platform for Functional Electrical Stimulation and Surface Electromyography
FTEXES (Functionalized TEXtiles for Electrical Stimulation) is a wearable platform based on sensorized garments (Smart Pants and Smart T-shirt) with integrated textile electrodes for surface electromyography (EMG) recording and functional electrical stimulation (FES). This single-center, open-label, non-randomized study evaluates the usability of the system in a controlled laboratory setting. Fifteen participants (5 healthy adults, 5 patients with neuromotor disability, 5 healthcare professionals) take part in a single 45-60 minute session including donning, system setup, calibration, functional tasks (gait for the lower limb; reaching and grasping for the upper limb), doffing and skin inspection. Comfort, skin tolerability, stimulation-related discomfort, perceived usability, satisfaction and acceptability are assessed with standardized questionnaires. The quality of EMG signals recorded with textile electrodes is evaluated as a secondary objective. The study has no therapeutic purpose for individual participants.

描述
Inclusion Criteria:
- Healthy adults: age 18 years or older; no neuromotor disability; written informed consent.
- Patients: age 18 years or older, or 12-17 years with parental/guardian consent and minor's assent; neuromotor disability compatible with the use of the FTEXES system; indication for FES confirmed by a physiatrist. Previous FES experience is not required.
- Healthcare professionals: professional qualification consistent with study activities (physiotherapist or physiatrist).
Exclusion Criteria:
- Missing informed consent (for minors: missing parental/guardian consent and/or minor's assent).
- Inability to understand study aims and procedures or to follow instructions.
- Clinical, functional, cognitive, behavioral or skin conditions that make participation unsafe or inappropriate, in the investigator's judgment.
- Skin lesions, abrasions, dermatitis, irritation, infection or other dermatological conditions in device contact areas.
- Healthy adults: known neuromuscular disease, recent trauma, direct involvement in FTEXES development, or professional/academic dependency on the Principal Investigator.
- Patients: absence of motor disability compatible with the FTEXES system, or no indication for / unsuitability to FES in the physiatrist's judgment.
- Healthcare professionals: lack of professional qualification or of competence in the use/configuration of FES systems.
- Any other condition that, in the investigator's judgment, may interfere with study conduct or endpoint assessment.

实验性的：Healthy adults
Five adults aged 18 years or older without neuromotor disability use the FTEXES system in a single session. |
Sensorized textile garments (Smart Pants for the lower limb, Smart T-shirt for the upper limb) with integrated textile electrodes, connected to a CE-marked FES stimulator (HASOMED RehaMove3) and a CE-marked surface EMG system (FreeEMG 1000). Single session of about 45-60 minutes: donning, setup, calibration, functional tasks (gait cycle or reaching/grasping), doffing and skin inspection. |

实验性的：Patients with neuromotor disability
Five patients aged 12 years or older with neuromotor disability compatible with FES, as assessed by a physiatrist, use the FTEXES system in a single session. |
Sensorized textile garments (Smart Pants for the lower limb, Smart T-shirt for the upper limb) with integrated textile electrodes, connected to a CE-marked FES stimulator (HASOMED RehaMove3) and a CE-marked surface EMG system (FreeEMG 1000). Single session of about 45-60 minutes: donning, setup, calibration, functional tasks (gait cycle or reaching/grasping), doffing and skin inspection. |
