Summary
Home-based progressive resistance exercise is feasible for venous leg ulcer patients. While calf muscle pump function improved, its impact on ulcer healing needs more study.
Area of Science:
- Vascular Medicine
- Exercise Physiology
- Wound Care
Background:
- Venous leg ulcers (VLUs) are common and associated with impaired calf muscle pump (CMP) function.
- Improving CMP function may enhance VLU healing, but effective community-based interventions are needed.
Purpose of the Study:
- To assess the feasibility of a home-based progressive resistance exercise (PRE) program to improve CMP function in patients with VLUs.
- To evaluate the impact of PRE on CMP function and VLU healing parameters.
Main Methods:
- A 12-week randomized controlled trial comparing PRE (heel raises) plus compression to usual care plus compression.
- Stratified randomization by ulcer duration and size.
- Calf muscle pump function assessed by air plethysmography; ulcer parameters measured with SilhouetteMobile.
Main Results:
- Forty participants were randomized. The PRE group showed significantly greater improvement in calf ejection fraction (18.5% difference, p<0.05).
- Adherence to exercise was high (81%) with no increase in adverse events.
- No significant differences were observed in ulcer healing rates or time to healing between groups.
Conclusions:
- A community-based randomized trial of home-based PRE for VLU patients is feasible.
- The exercise program effectively improved calf ejection fraction.
- Further research is required to determine the effect of this exercise intervention on VLU healing.

01:26Varicose Veins II: Diagnostic Studies and Interprofessional Care
Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
01:26Varicose Veins I: Introduction
Varicose veins, or varicosities, are abnormally dilated and twisted superficial veins caused by venous valve incompetence. This condition commonly affects the lower extremities, especially the saphenous veins, due to the higher pressure from prolonged standing and walking. However, varicosities can also occur in other areas, such as the esophagus, vulva, spermatic cords, and anorectal region.Etiology and typesPrimary varicose veins, often idiopathic, are more common in women due to inherent...

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration.
