Quantitative motor assessment in amyotrophic lateral sclerosis
Neurology
|July 1, 1986
Summary
A new standardized protocol, the Tufts Quantitative Neuromuscular Exam (TQNE), provides reliable measurements for tracking Amyotrophic Lateral Sclerosis (ALS) progression and assessing treatment effectiveness.
Area of Science:
- Neurology
- Clinical Measurement
Background:
- Accurate assessment tools are crucial for understanding Amyotrophic Lateral Sclerosis (ALS) natural history.
- Evaluating the efficacy of ALS therapies requires sensitive and reliable outcome measures.
Purpose of the Study:
- To introduce a standardized protocol for quantitative neuromuscular evaluation in ALS patients.
- To establish a reliable and sensitive measurement tool for clinical trials and natural history studies.
Main Methods:
- Development of the Tufts Quantitative Neuromuscular Exam (TQNE), a 29-item protocol.
- TQNE assesses pulmonary function, oropharyngeal function, timed functional activities, and isometric strength.
- Utilized an electronic strain gauge for isometric strength measurements.
Main Results:
- The TQNE protocol generates interval data sensitive to clinical change.
- The examination requires approximately one hour for administration.
- Demonstrated excellent test-retest reliability for the TQNE.
Conclusions:
- The Tufts Quantitative Neuromuscular Exam (TQNE) offers a reliable and sensitive method for ALS assessment.
- TQNE can aid in documenting disease progression and evaluating therapeutic interventions in ALS research.
