Summary

Patients with chronic venous disease show significantly impaired calf muscle strength and endurance. This suggests that improving muscle function may aid in healing and preventing venous leg ulcers.

Area of Science:

  • Vascular Medicine
  • Musculoskeletal Physiology

Background:

  • Chronic venous disease (CVD) significantly impacts lower limb function.
  • Venous leg ulcers are a common manifestation of advanced CVD.
  • Calf muscle dysfunction is suspected in CVD patients but requires objective assessment.

Purpose of the Study:

  • To evaluate calf muscle strength and endurance in patients with CVD and healed venous ulcers.
  • To compare muscle function between CVD patients and healthy controls.
  • To identify potential therapeutic targets for improving outcomes in CVD.

Main Methods:

  • Recruited 49 patients with recently healed venous leg ulcers and 20 healthy controls.
  • Performed duplex scan evaluation of leg veins for all participants.
  • Conducted isokinetic measurements to assess calf muscle strength and endurance.

Main Results:

  • Calf muscle function was significantly impaired in CVD patients compared to controls.
  • Peak torque relative to body weight (strength) was reduced (P=0.049).
  • Total work performed (endurance) was also significantly reduced (P=0.05).

Conclusions:

  • Patients with chronic venous disease exhibit significant calf muscle impairment.
  • Reduced muscle strength and endurance are evident even after venous ulcer healing.
  • Further research is warranted to explore the benefits of muscle strengthening programs for CVD management and ulcer recurrence prevention.
