NCT06031922

Brief Summary

The goal of this observational study is to investigate the effectiveness of NMPKs versus MPKs in persons with an LLA in the standard healthcare system in the Netherlands taking all levels of the ICF model into account. Our main aim is to assess the effect of MPK use compared to NMPK use on walking distance, as this is one of the most used outcome variables in literature and thus enables comparison with previous studies. Our secondary aim is to investigate the effect of NMPKs versus MPKs on all ICF-levels: body structures and function, activities and participation. Participants will be seen four times in a year. During these measurement moments they will:

  • Perform two physical tests
  • Fill out a set of questionnaires
  • Wear an activity tracker for one week

Outcome Measures

Primary Outcomes (1)

  • 6 Minute Walking Test (6MWT)

    The 6-minute walk test is used to measure functional capacity. The maximum distance a participant can walk within 6 minutes is measured. The course can be 10, 30 or 50 meters. The participant can use their walking aid if needed.

    This test takes 6 minutes and is performed at T0 (week 1 after inclusion), T1 (week 7 after inclusion), T2 (week 12 after inclusion) and T3 (week 52 after inclusion)

Secondary Outcomes (7)

  • Short Questionnaire to Assess Health-enhancing physical activity (SQUASH)

    Participants were asked to fill out the questionnaire at T0 (week 1 after inclusion), T1 (week 7 after inclusion) and T3 (week 52 after inclusion), with a normal/standard week for them in mind.

  • Timed Up and Go test (TUGtest)

    This test is performed at T0 (week 1 after inclusion), T1 (week 7 after inclusion), T2 (week 12 after inclusion) and T3 (week 52 after inclusion). It can take up to three minutes.

  • Activities-Specific Balance Confidence Scale Nederlands (ABC-NL)

    Participants were asked to fill out the questionnaire at T0 (week 1 after inclusion), T1 (week 7 after inclusion) and T3 (week 52 after inclusion), based on their current situation that day.

  • Cost-questionnaire

    At T0 (week 1 after inclusion) and T3 (week 52 after inclusion), participants were asked to fill out the questionnaire over a retrospective period of six months.

  • Prosthesis Evaluation Questionnaire (PEQ)

    Participants were asked to fill out the questionnaire at T0 (week 1 after inclusion), T1 (week 7 after inclusion) and T3 (week 52 after inclusion) over a retrospective period of four weeks.
