About sEMG

(Click your activity of interest below to observe hand muscle activity pattern)

Handmaster Plus tests 2-4x as effective as simple squeeze balls and spring-loaded hand exercise products in strengthening and balancing the 18 hand muscles. Surface electromyography (sEMG) clearly illustrates that all hand muscles are used in all activities. Poor performance, overuse and repetition injuries occur when muscle combinations are ignored and the body is prepared improperly for specific activity.
