Ergonomic Adjustable Hand Gripper

Compact unit size: ~14.5 x 6.5 x 4 cm; weight per unit: ~220 g. Comes as a matched pair of hand grip strengtheners. Body made from soft-touch plastic with integrated rubberised non-slip grip zones; internal spring is premium stainless steel for high elasticity and fatigue resistance. Resistance adjustment is achieved by rotating a central knob — clockwise increases load (5–60 kg / 11–132 lbs), counter-clockwise decreases it. Handle shape accommodates varying hand anatomy, from petite to broad palms, and suits users aged 13+ including seniors. Trains grip endurance, wrist stability, and forearm muscle coordination. Daily use supports functional recovery following hand injuries, inflammatory joint conditions (e.g., rheumatoid arthritis), nerve compression syndromes (e.g., carpal tunnel), soft tissue inflammation (tendovaginitis), and post-operative tendon rehabilitation. Also used by performers and athletes to maintain fine motor control and prevent overuse strain. Lightweight and portable — no setup or power required. Fits in drawers, backpacks, or therapy kits. Use solo for self-paced rehab, synchronously for symmetry work, or collaboratively with a clinician or training partner — meeting diverse needs across home, clinic, studio, and field environments.
