A supervised exercise program significantly improved calf muscle pump function and strength in patients with chronic venous insufficiency (CVI). This structured physical conditioning offers potential benefits for managing CVI progression.

Area of Science:

  • Vascular Medicine
  • Exercise Physiology
  • Rehabilitation Science

Background:

  • Impaired calf muscle pump function is a key factor in the progression of chronic venous insufficiency (CVI).
  • Understanding the impact of targeted exercise on venous hemodynamics is crucial for CVI management.

Purpose of the Study:

  • To investigate if a supervised exercise program can enhance calf muscle strength and improve venous hemodynamics in patients diagnosed with CVI.
  • To evaluate the efficacy of physical therapy in improving calf muscle function and related clinical outcomes.

Main Methods:

  • A randomized, prospective trial involving 31 patients with CVI (CEAP 4-6) was conducted.
  • Participants were assigned to either a control group or a therapy group receiving a calf-strengthening exercise program, alongside compression hosiery.

  • Calf muscle strength, venous filling index, ejection fraction, and residual volume fraction were measured using dynamometry and air plethysmography (APG) at baseline and after 6 months.

    • Main Results:

    • The exercise group demonstrated significant improvements in calf pump function, with normalized residual volume fraction and increased ejection fraction compared to the control group.
    • Isokinetic peak torque, a measure of muscle strength, was significantly enhanced at both slow and fast speeds in the therapy group.
    • While reflux levels remained elevated in both groups, the intervention positively impacted key indicators of calf muscle strength and pump efficiency.

    Conclusions:

    • A 6-month structured exercise program effectively improved calf muscle pump function and dynamic strength in patients with CVI.
    • Targeted physical conditioning of the calf musculature presents a beneficial therapeutic option for individuals with severe CVI.
    • Further research is warranted to explore the long-term benefits and broader applications of exercise interventions for CVI patients.
