Transcript of Hand-Held Dynamometer

Dynam meter Hand-Held Dynamometer means : A dynamometer is an apparatus that measures mechanical force, speed, torque or power. Hand-Held Introduction The hand held dynamometer enables medical theropists to detrmine the force across the range of motion in patient's joints. Stand-Out Benfits 1- Digitally records patient rehabilitation over time.
2- Dual evaluation feature eliminates need for separate
devices.
3- Portable and easy to use.
4- Training tool for therapists.
5- Motivational use for patients as results improve. Features 1-Three objective measurements from a single device:
Force
Range of motion
Force/Range of motion simultaneously
2- Rechargeable battery-operated — 5 hour duration.
3- Software support includes patient database capability.
4- Range of motion — 0–359° ± 1° accuracy.
5- Force — 0 to 80 kg ± 0.1 kg accuracy. Applications of Hand-Held Hand Grip test The purpose of this test is to measure maximum isometric strength of the hand and foream muscles.





Procedure & Variations.
Scoring. Validity
Reliability
Advantages & Disadvantages Hip test Handheld dynamometry (HHD) is a promising tool for obtaining reliable hip strength measurements in the clinical setting. Studies Hand-Held dynamometer in children with traumatic brain injury (TBI).

Purpose :
comparing TBI children with typical devolpment children (TD).
Method :
Results :
Reliability ranged from 0.91 to 0.99 TBI children standrad error vaired from 0.51 to 1.52 kg.
Conclusion : Method :
Fifty healthy individuals (29 women), aged 25±5 years were included. Two physiotherapist students (one female, one male) of different upper-extremity strength performed the measurements. Questions Thank You isokinetic Dynamometer Iso = equal; kinetos = move
Definition: one kind of muscle contraction that occurs when the rate of movement is constant.
Not occur in the living body without using special machine (isokinetic dynamometer)
first introduced by Hislop and Perrine in 1967.
Equal motion speed with accommodating resistance
