The Eforto® device captures muscle endurance impairments with twice the sensitivity compared to traditional dynamometers.
Unique validated system for accurate and reliable monitoring grip strength and muscle fatigability. Simple and quick (self-)testing suitable for regular clinical practice and remote patient monitoring.
Benefits
- Outperforms traditional dynamometers
- Enhanced comfort & less pain: ergonomic rubber bulb, less strain on joints
- Reliable across hand sizes: minimal impact from hand morphology
- Superior sensitive for weak grip: relevant for frail or impaired patients
- Captures dynamic grip strength: Ideal for measuring muscle fatigability
- High precision with auto-calibration
- Ultra-lightweight (100 g / 3.53 oz): Easy to use by weaker patients
