Accuracy, reproducibility, and variability of hand-held dynamometry in motor neuron disease.
A spring-loaded device that "breaks" at preset forces was used to assess readings obtained by hand-held dynamometry by three raters with varying experience in the method. Overall accuracy (3%), but not reproducibility or variability, was improved by greater experience. Readings obtained jointly by three raters had 53% greater variability than those obtained by a single rater. Nine muscle groups...
متن کاملInterrater reliability of hand-held dynamometry.
Two raters performed hand-held dynamometer testing of six muscle groups of 30 patients to determine the interrater reliability of the procedure. The six muscle groups tested were the shoulder external rotators, elbow flexors, wrist extensors, hip flexors, knee extensors, and ankle dorsiflexors. The patients were of eight different diagnostic groups, with most having hemiparesis secondary to cer...
متن کاملValidity and reproducibility of hand-held dynamometry in children aged 4-11 years.
OBJECTIVE To evaluate validity and reproducibility of hand-held dynamometry in 11 different muscle groups in children. DESIGN AND PATIENTS Maximum isometric muscle strength was measured with a calibrated hand-held dynamometer in 61 patients aged 4-11 years who had been referred to our specialist centre in the past 3 years because of suspected myopathy. All the patients had had muscle biopsy. ...
متن کاملReliability of hand-held dynamometry in spinal muscular atrophy.
We have assessed the reliability of hand-held myometry in 33 patients with spinal muscular atrophy (SMA), testing elbow flexion, handgrip, three-point pinch, knee flexion, knee extension, and foot dorsiflexion, and determining intraclass correlation coefficients (ICC). Interrater reliability was high for upper limbs, with an ICC of 0.92 for three-point pinch and 0.98 for elbow flexion and grip....
متن کاملReproducibility and accuracy of measurements with a hand held autorefractor in children.
AIM To determine reproducibility and accuracy of the Nikon Retinomax autorefractor when used with children who were made cycloplegic. METHODS Autorefraction and retinoscopy or subjectively refined retinoscopy (where, under the patient's direction, the refraction was varied until the best visual acuity was achieved) were performed on the right eye of 47 children, age 11-93 months. Autorefracti...
