Study summary

Early diagnosis is a key factor for effective treatment of multiple sclerosis. Accelerometer and gyroscope measurement of tremor could screen potential motor control dysfunction and predict a risk for development of multiple sclerosis.

Read the detailed description

The aim of this study is to test whether specially developed accelerometer and gyroscope can differentiate pattern of resting postural tremor in healthy and people with multiple sclerosis.

Spectral analysis and the correlation of the average signal spectra will be computed. Moreover, categorization based on the tremor component according to the maximum likelihood estimation will be done.

Study population

People with MS and healthy volunteers

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

Group 1:

  • Definite diagnosis of MS
  • prevailed motor deficit of upper extremities, but without visible tremor
  • stable clinical status in the preceding 3 months
  • Expanded Disability Status Scale score (EDSS) ≥ 2 ≤ 7.5, and
  • no therapy in the preceding month

Group 2:

  • Healthy volunteers in the age of 20-70 years will be employed
  • There will be defined as persons without any neurological disease diagnose at the time of the measurement.

Exclusion criteria

Exclusion Criteria (both groups):

Patients with factors disturbing mobility (e.g. stroke, pregnancy, fractures) were excluded from the study.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Groups and cohorts

  • Patients with multiple sclerosis

    MS patients will be chosen by an independent neurologist.

    Behavioral: Examination of tremor and upper hand functions

  • Healthy volunteers

    Healthy controls will be paired by age and sex with MS patients.

    Behavioral: Examination of tremor and upper hand functions

Interventions

  • BehavioralExamination of tremor and upper hand functions

    Participants will be only examined. They will not undergo any intervention.
