Study summary

The aim of the study is to investigate the short-term (within 2 weeks) effects of resistance exercise with and without compression garments on lower limb lymphedema(LLL). Additionally, the study will explore the immediate response in LLL to resistance exercise (2 hours and 24 hours post-exercise).

Participants will continously wear a circumfencential sensor at the calf (CIMON from Icompression) under a compression garment and an activity tracker (SENS Motion from SENS Innovation Aps) at the thigh for 3 periods (two with supervised exercise sessions of 2 weeks and one control period).

Participants will attend supervised resistance exercise 2-3 times per week for 2 periods of 2 weeks (one with compression garment and one without). Assessments with the principal investigator will be scheduled before and after every 2 week period. Participants will keep a digital diary or diary in paper of their lymphedema related symptoms and experienced issues with the sensors or app.

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

  • verified diagnosis of lymphedema of the lower limb
  • completed compression bandaging
  • adherence to compression garment in daytime (minumum 5-6 days per week)
  • calf circumference > 35 and \<75 cm

Exclusion criteria

Exclusion Criteria:

  • severe neuropathy of the lower leg
  • severe skin problems or wounds at the lower leg
  • cellulitis, DVT or acute injuries of the lower limb \< 2 months prior to inclusion
  • ongoing treatment for cancer
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.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

What researchers measure

Primary outcomes

  1. Lower leg circumference

    circumferential sensor CIMON, measured in Picoferens (pF)

    Time frame: 14 days

Secondary outcomes

  1. Lower Limb volume

    perometry, volume (mL)

    Time frame: 14 days

  2. Lower Limb volume

    circumferential measurements, 8 cm interval, converted to volume (mL)

    Time frame: 14 days

  3. Edema of the foot and ankle

    Figure of eight with tape measure, (cm)

    Time frame: 14 days

  4. Extracellular fluid of the lower limb

    Bioimpedance Spectroscophy, (L-dex)

    Time frame: 14 days

  5. Body composition

    Bioimpedance Spectroscophy, One measurement provides the following data: Total Body Water (L/%) , Extracellular fluid (L/%), Intracellular fluid (L/%), Skeletal muscle mass (kg/%), Fat mass (kg/%), Fat free mass (kg/%)

    Time frame: 14 days

  6. Segmental body composition of the lower limbs

    Bioimpedence Spectroscophy, One measurement provides the following data: Total Body water (L), Extracellular fluid (L), Intracellular fluid (L), Skeletal Muscle Mass(kg), Lean soft tissue (kg)

    Time frame: 14 days

  7. Self reported lymphedema symptoms

    Pain, tension, heaviness, tinkling, numeric ranking scale 0-10

    Time frame: 14 days

  8. Physical activity

    Daily number of minutes in activity (defined as the sum of time spent with standing, walking, cycling and high intensity activity) registered by a activity sensor (SENS Motion). Level of physical activity time per 24 hours at the following categories: lying, sitting, standing, walking, brisk walking, biking, high intensity activity

    Time frame: 14 days

  9. Adverse events

    E.g. skin irritation, cellulitis, severe muscle injury, number of events

    Time frame: 14 days

  10. Adherence to compression

    Adherence to compression garments = 7 days a week, yes or no, if no - number of days with compression per participant

    Time frame: 14 days

  11. Adherence to study

    Completion of supervised exercise sessions and application of the sensors, number of exercise sessions attended and number of days with sensors applied per participant

    Time frame: 8 weeks

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 May 2026 (actual). Primary completion is estimated for Mar 2027, 10 months after the start.

Of 175 non-industry interventional studies with no phase under Lymphedema, half reached primary completion within 27 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 68. This study's planned 10 months is below that.

Counting every sponsor, half of 197 studies reached it within 25 months; a quarter within 9 and three quarters within 64.

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 Sep 18, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
