  2. METHODS 11 male subjects

  3. RESULTS Musclesmeasured Grip measures Reductions due to the longer handle during wrenching Reductions due to the grip type during wrenching

  4. DISCUSSION • Longer handles reduce the muscle activity and grip pressure • Larger handle reduced the grip pressure, and some muscle activity • Both depend on the wrenching direction • This provides an initial look into the effects wrench handle design have on workers
