The purpose of this study was to document the intrarater reliability of manual muscle test (MMT) grades in assessing muscle strength in patients with Duchenne's muscular dystrophy (DMD). [] Key Method Subjects were 102 boys, aged 5 to 15 years, who were participating in a double-blind, multicenter trial to document the effects of prednisone on muscle strength in patients with DMD. Four physical therapists participated in the study.

Clinical evaluator reliability for quantitative and manual muscle testing measures of strength in children

QMT shows greater reliability and is easier to implement than MMT, and will be a superior measure of strength for use in pediatric, neuromuscular, multicenter clinical trials.

Motor assessment in patients with Duchenne muscular dystrophy.

The MFM scale was a useful instrument in the follow up of patients with DMD and is a more comprehensive scale to assess patients and very good for conducting trials to evaluate treatment.

Manual muscle strength testing: intraobserver and interobserver reliabilities for the intrinsic muscles of the hand.

Reliability and validity of the Medical Research Council (MRC) scale and a modified scale for testing muscle strength in patients with radial palsy.

Medical Research Council and modified Medical Research Council scales are measurements with substantial inter-rater and intra- rater reliability in evaluating forearm muscles.

Inter-rater reliability of the modified Medical Research Council scale in patients with chronic incomplete spinal cord injury.

The inter-rater reliability of the modified MRC scale was found to be high in the majority of tested variables, but the results suggest that discrepancy among trained observers does exist.

Hand-held dynamometry for assessment of muscle strength in patients with inflammatory myopathies.

HHD demonstrated strong reliability, construct validity and responsiveness in myositis patients, and longitudinal analysis showed a significant and strong association between the HHD and MMT as well as 2016 ACR/EULARMyositis response criteria.

Objective evaluation of muscle strength in infants with hypotonia and muscle weakness.

Intra-Rater and Inter-Rater Reliability of the 10-Point Manual Muscle Test (MMT) of Strength in Children with Juvenile Idiopathic Inflammatory Myopathies (JIIM)

The total, proximal, and peripheral Manual Muscle Test (MMT) score, using the 0-10 point scale, has acceptable reliability in JIIM patients.

Reliability of quantitative muscle testing in healthy children and in children with Duchenne muscular dystrophy using a hand-held dynamometer.

The results suggest that the hand-held dynamometer can be used as a reliable instrument in measuring the isometric strength of selected muscles in children.

Clinical reliability of manual muscle testing. Middle trapezius and gluteus medius muscles.

Using manual muscle testing to make accurate clinical assessments of patient status is of questionable value, and the results showed that interrater reliability for right and left middle trapezius and gluteus medius muscles was low.

Reliability for an evaluation method that will provide an objective foundation on which to claim a drug or therapeutic procedure does or does not have an effect in treating Duchenne muscular dystrophy is demonstrated.

Assessment of muscle strength in Duchenne muscular dystrophy

Muscle strength in 23 patients with Duchenne dystrophy was tested against gravity and manual resistance during an 8-year period. The data show striking linearity in rate of loss of strength with age

Clinical investigation in duchenne dystrophy: 2. Determination of the “power” of therapeutic trials based on the natural history

A prospective study of 114 patients with DMD provided data for “power” calculations for future therapeutic trials. There was a decline in strength of 0.4 units per year (on a 0‐10 scale).

It is indicated that oral leucine failed to produce a therapeutic response over a 1‐year double‐blind, controlled trial of Duchenne muscular dystrophy.

Practical analysis of variability of muscle function measurements in duchenne muscular dystrophy

To determine the possible sources of variation in performance indicators used in therapeutic trials, electrical stimulation techniques were used to measure contractile properties of the adductor

It is demonstrated that nifedipine is safe to administer in children, but that it is without beneficial effect on the course of DMD.

It is concluded thatprednisone produces a rapid increase in muscle strength in patients with Duchenne dystrophy and that this improvement is maximal at a prednisone dosage of 0.75 mg/kg or less.
