Study details

- Human
Researchers developed and validated the 14-item Muscle Cramp Impact Index (MCII), a patient-reported questionnaire covering cramp frequency, sleep interference and effects on daily activities. The study included 105 adults with recent muscle cramps recruited from several types of clinics, including amyotrophic lateral sclerosis (ALS) clinics. The tool showed excellent test-retest reliability, but its usefulness for tracking change still needs further study.
Why this matters
The MCII could help clinicians and researchers assess effects of cramps beyond frequency and intensity, including sleep and daily functioning. The study does not show that the questionnaire improves cramp treatment or outcomes, and it does not yet establish how well it works specifically in people with ALS.
Limitations and context
This was a scale-development and validation study, not a treatment trial. Participants had different underlying conditions, and the source does not report separate ALS results. Further evaluation is needed to determine whether the measure detects changes over time and works across additional cramp populations. Some information relied on self-report, and mailed questionnaires could not verify respondent identity.
