======Handgrip Strength Test====== **Materials: **{{$demo.materials_description}}\\ **Difficulty: **{{$demo.difficulty_description}}\\ **Safety: **{{$demo.safety_description}}\\ \\ **Categories:** {{$demo.categories}} \\ **Alternative titles:** Grip Dynamometer Test ====Summary==== {{$demo.summary}} ====Procedure==== - Gather a calibrated handgrip dynamometer, data sheet, and a timer; record age, sex, hand dominance, height, and body mass. - Adjust the grip so the handle rests across the middle of the fingers and the base sits on the heel of the palm. - Instruct the subject to stand or sit tall with shoulders relaxed; set the elbow either at ~90° by the side or in the standardized position your protocol specifies. - Ask the subject to take a breath, then squeeze the dynamometer as hard as possible without swinging the arm or using the body for leverage. - Maintain the maximal squeeze for about 3–5 seconds while the tester observes for compensations. - Release, rest at least 15–30 seconds (longer if needed), then repeat. - Perform 2–3 trials per hand; alternate hands if testing both. - Record the best value for each hand and note the protocol and position used; optionally compute the average or compare dominant vs non-dominant sides. ====Links==== Grip Strength Protocol - Measurement & Evaluation Techniques: {{youtube>XJ4TcueMfRg?}}\\ Grip Strength Testing with a Dynamometer - Physical Therapy Education Solutions: {{youtube>cguUks_Eby0?}}\\ 📄 Handgrip Strength Test - Topend Sports: [[https://www.topendsports.com/testing/tests/handgrip.htm]]\\ ====Variations==== * Arm position changes (elbow at 90° by the side, arm hanging by the side, or standardized shoulder flexion) depending on the chosen protocol. * Squeeze duration set to 3 seconds (e.g., Eurofit) instead of 5 seconds. * Older-adult protocols (e.g., one practice trial, best of three with ~30 seconds rest). * Report formats: dominant-hand only, best of either hand, or average of both hands. * Seated versus standing posture; specify wrist angle (neutral versus slight extension) for consistency. ====Safety Precautions==== * Screen for recent hand, wrist, elbow, or shoulder injury before testing. * Ensure the dynamometer is calibrated and the grip size is adjusted to avoid strain. * Use a stable stance or seated position to prevent loss of balance during maximal effort. * Instruct “no breath holding” in at-risk populations to reduce Valsalva-related blood pressure spikes. * Stop immediately if there is pain, tingling, or dizziness. ====Questions to Consider==== * Why test both hands rather than just the dominant hand? (Dominance affects results; testing both can reveal asymmetries of clinical or sport relevance.) * How does body position influence scores? (Changes in shoulder/elbow/wrist angles alter leverage and muscle recruitment, affecting measured force.) * What does a large left–right difference suggest? (Possible dominance effects, injury history, or neuromuscular imbalance that may warrant follow-up.) * Why standardize squeeze time and rest intervals? (Consistency improves reliability and allows valid comparison to norms.) * Are handgrip scores a good proxy for whole-body strength? (They correlate with general strength but do not replace muscle-group–specific tests.)
