An observational study in Movement Disorders (Incl Parkinsonism), Parkinsonian Disorders and Attention Impaired, sponsored by Inonu University. Enrolling by invitation at 1 site in Turkey. Open to participants aged 40 Years to 80 Years. Per ClinicalTrials.gov, last updated 2024-02-28.

Why
  1. The study's listed conditions name Parkinsonian Disorders, a narrower term within Movement Disorders.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

Our study was planned to analyze motor function, endurance and sleep attention information in Parkinson's patients with detailed and objective measurements.

Read the detailed description

Parkinson's Disease (PD) is a neurodegenerative disease that occurs with the loss of dopaminergic neurons in the basal ganglia (BG) and subsequently affects multiple brain regions. There are studies that evaluate executive functions rather than cognitive functions in Parkinson's patients. However, objective evaluations of the attention parameter are quite rare. Accordingly, our study was planned to examine the effects of motor function, depression and sleep on attention in Parkinson's patients with detailed and objective measurements. Parkinson's patients (n=27) and healthy controls (n=27) aged between 40-85 will be included in the study. Balance evaluation of the individuals participating in the study was carried out by functional reaching test, one-leg standing test and Berg balance scale; Endurance with a 30-second sit-and-stand test; reaction time; with mobile application; muscle strength by hand dynamometer; functional mobility with time up and go test; walking speed, with 10 m walk test; attention with the P300 device; depression, with the Beck depression scale; Sleep quality will be assessed with the Pittsburg sleep questionnaire. At the end of the study, the effects of motor functions, sleep and depression on attention will be examined and compared with healthy controls.

What researchers measure

Primary outcomes

  1. TUG

    functional mobility

    Time frame: second, day 1, Values over 12 seconds indicate the risk of falling

  2. 10 m walking test

    walking speed

    Time frame: second, day 1, lower results indicate better values, higher results indicate worse results

  3. 30 sec sit-stand test

    endurance

    Time frame: again,day 1, higher results indicate better values, lower results indicate worse results

  4. berg balance test

    balance

    Time frame: score, day 1, The score is between 0-56. A high total score indicates a good result

  5. one leg stance test

    balance

    Time frame: second, day 1, higher results indicate better values, lower results indicate worse results

  6. functional reach test

    balance

    Time frame: centimeter, day 1, higher results indicate better values, lower results indicate worse results

  7. hand dinamometer

    strenght

    Time frame: kilogram, day 1, higher results indicate better values, lower results indicate worse results

  8. mobil application

    reaction time

    Time frame: second, day 1, lower results indicate better values, higher results indicate worse results

  9. Pittsburg Sleep Quality İndex

    sleep

    Time frame: score, day 1, The score is between 0-21. A high total score indicates a bad result.

  10. Beck Depression

    depression

    Time frame: score,day 1, The total score is between 0-63. A high total score indicates that the result is bad.

  11. P300

    attention

    Time frame: second, day 1, lower results indicate better values, higher results indicate worse results

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jan 2024 (actual). Primary completion is estimated for Mar 2024, 2 months after the start.

Of 37 observational studies under Parkinsonian Disorders, half reached primary completion within 74 months of starting (the median), counting those still running; a quarter within 34. This study's planned 2 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 28, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
