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.

Beskrivning
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.

Experimentell: 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. |
|
Experimentell: 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. |
|
Övrig: Healthcare professionals
Five healthcare professionals (3 physiotherapists, 2 physiatrists) configure and operate the FTEXES system and evaluate its usability from the operator's perspective. |
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).
