Toward digitally supported self-assessment of patients with idiopathic inflammatory myopathies
Authors' conclusion
Patient-performed functional tests are reliable, scalable alternatives to MMT8, with gait analysis providing complementary insights.
Study context
- Population
- Patients with idiopathic inflammatory myopathies (IIM)67.9% female
- Participants
- 28 patients
- Exposure
- Patient-performed functional tests and inertial sensor-based gait analysis vs manual muscle testing (MMT8)
- Outcome
- Correlation of gait parameters with MMT8
- Follow-up
- T0
Methodological detailsshared decision-making, inertial sensor-based gait analysis, electronic patient-reported outcomes
- Shared decision-making
- Inertial sensor-based gait analysis
- Electronic patient-reported outcomes
Main finding

Walking speed vs MMT8 (moderate correlation)
r = 0.545
p = 0.004
Stride length vs MMT8 (moderate correlation)
r = 0.580
p = 0.002
Observational data: associations, not effects.
Further findings
Agreement between patient- and healthcare professional (HCP)-recorded functional test results · baseline and 3 months
