Clinically Informed Adjustable Grip Tool

Sized at 16 × 11 × 2 cm for easy storage and transport while maintaining structural rigidity. Delivers fully adjustable resistance from 10 kg to 40 kg via intuitive mechanical push-buttons — zero electronics, zero maintenance, zero variability in output over time. Built with fatigue-tested piano wire springs, high-tensile steel load arms, impact-resistant polypropylene (PP) housing, and textured TPR grips designed for secure handling across varying hand sizes and moisture levels. The extended handle design improves palmar coverage by 32%, shifting pressure away from sensitive anatomical zones like the thenar eminence — supporting longer hold durations and improved tolerance during repetitive therapeutic exercises. All materials comply with REACH Annex XVII and bear UKCA marking — confirming legal conformity for sale and use as consumer fitness equipment in Great Britain. Developed for integration into post-operative hand therapy plans, employer-supported musculoskeletal health strategies aligned with HSE guidance, and budget-conscious sports development programmes aiming for measurable, sustainable hand strength outcomes.
