Structured Home-Based Exercise and Education for Chronic Venous Insufficiency

2026年8月28日 更新者：Alp Ozel、Abant Izzet Baysal University

Effects of a Structured Home-Based Exercise and Education Program on Clinical and Functional Outcomes in Individuals With Chronic Venous Insufficiency: A Randomized Controlled Trial

The goal of this clinical trial is to learn whether a structured home-based exercise and education program can improve quality of life and leg symptoms in adults with chronic venous insufficiency. Chronic venous insufficiency occurs when the veins in the legs do not return blood effectively toward the heart. The main questions the study aims to answer are: Does the exercise and education program improve quality of life related to chronic venous insufficiency after 8 weeks, and is any improvement maintained at Week 12? Does the program reduce leg symptoms after 8 weeks, and is any improvement maintained at Week 12? Researchers will compare participants who receive the structured exercise and education program in addition to standard medical care with participants who receive standard medical care and routine lifestyle advice without structured exercise training. A total of 120 participants will be assigned by chance to one of the two groups. Participants will: Continue the standard medical care recommended by their physicians. Attend assessments at the beginning of the study, at Week 8, and at Week 12. Complete questionnaires and tests assessing quality of life, leg symptoms, walking capacity, calf muscle endurance, physical activity, pain, heaviness, and lower-limb swelling. Participants assigned to the intervention group will also attend a 30- to 45-minute group education session, perform home-based exercises for 20 to 30 minutes per day on at least 5 days per week for 8 weeks, record their exercise sessions, and receive weekly follow-up by telephone or message.

详细说明

The sample size was calculated using R version 4.5.3 with the pwr package. Previously published VEINES-QOL change data suggested a standardized effect size of approximately 0.72. However, because this estimate was derived from a single small study with very low-certainty evidence, a more conservative effect size of Cohen's d = 0.55 was prespecified. For a two-sided independent-samples comparison with a significance level of 0.05 and 80% statistical power, 53 participants were required in each group (106 participants in total). The target enrollment was increased to 120 participants to allow for potential attrition. The allocation sequence will be generated before participant enrollment by a staff nurse designated to manage the allocation process, using a prespecified script based on the blockrand package in R version 4.5.3, with a 1:1 allocation ratio and randomly varying block sizes. The designated staff nurse will otherwise not be involved in eligibility assessment, participant enrollment, intervention delivery, or outcome assessment. The sequence will be maintained in a password-protected electronic allocation system accessible only to the designated staff nurse. After eligibility has been confirmed, written informed consent has been obtained, and baseline assessments have been completed, the enrolling researcher will submit the participant's unique study identification number for allocation. The system will release only the assignment for the current participant, while future assignments will remain concealed. Repeated-measures data will be analyzed using linear mixed-effects models. Group, time, and the group-by-time interaction will be included as fixed effects, with participant-specific random effects included as appropriate. Statistical tests will be two-sided, with the significance level set at 0.05.

措施说明
大体时间
Change in VEINES-QOL Score
大体时间：Baseline, Week 8, and Week 12
VEINES-QOL is the 25-item quality-of-life summary score derived from the 26-item VEINES-QOL/Sym questionnaire. It assesses the impact of chronic venous disease on symptoms, daily activities, and psychological well-being during the previous 4 weeks. Scores will be transformed to a 0-100 scale, with higher scores indicating better disease-specific quality of life. Change from baseline will be calculated at Weeks 8 and 12; positive change values indicate improvement.
Baseline, Week 8, and Week 12
Change in VEINES-Sym Score
大体时间：Baseline, Week 8, and Week 12
VEINES-Sym is the 10-item symptom summary score derived from the 26-item VEINES-QOL/Sym questionnaire. It assesses the frequency and severity of venous disease-related symptoms during the previous 4 weeks. Scores will be transformed to a 0-100 scale, with higher scores indicating fewer or less severe symptoms. Change from baseline will be calculated at Weeks 8 and 12; positive change values indicate symptom improvement.
Baseline, Week 8, and Week 12

次要结果测量

结果测量
措施说明
大体时间
Change in Six-Minute Walk Distance
大体时间：Baseline, Week 8, and Week 12
The Six-Minute Walk Test will be used to assess submaximal functional exercise capacity. Participants will be instructed to walk as far as possible for 6 minutes along a flat corridor of at least 30 meters. The total distance walked will be recorded in meters. Change from baseline will be calculated at Weeks 8 and 12; positive change values indicate improvement in functional exercise capacity.
Baseline, Week 8, and Week 12
Change in Heel Rise Test Repetitions
大体时间：Baseline, Week 8, and Week 12
The Heel Rise Test will be used to assess calf muscle endurance and plantar flexor function. Participants will stand on one leg and perform as many heel-rise repetitions as possible according to a standardized protocol. The number of correctly completed repetitions will be recorded, and the same lower extremity will be assessed at each visit. Change from baseline will be calculated at Weeks 8 and 12; positive change values indicate improvement in calf muscle endurance.
Baseline, Week 8, and Week 12
Change in IPAQ-SF Total Physical Activity
大体时间：Baseline, Week 8, and Week 12
The International Physical Activity Questionnaire-Short Form (IPAQ-SF) is a 7-item self-report questionnaire that assesses physical activity performed during the previous 7 days. The reported frequency and duration of walking, moderate-intensity activity, and vigorous-intensity activity will be used to calculate total physical activity in metabolic equivalent minutes per week (MET-min/week) according to the IPAQ scoring protocol. Higher values indicate a greater level of physical activity. Change from baseline will be calculated at Weeks 8 and 12; positive change values indicate increased physical activity.
Baseline, Week 8, and Week 12
Change in Lower-Extremity Volume
大体时间：Baseline, Week 8, and Week 12
Lower-extremity volume will be estimated from serial circumference measurements using the truncated-cone method. The index limb will be selected before randomization: the affected limb in unilateral disease, the limb with the higher CEAP class in bilateral disease, or the right limb if CEAP classes are equal. With the participant standing, circumferences will be measured using a non-elastic tape from 4 cm above the floor proximally at 4-cm intervals to just below the knee joint line. If the final interval is shorter than 4 cm, its actual length will be used. Segment volumes will be calculated and summed to obtain total volume in milliliters. The same limb and measurement levels will be used at all visits. Higher values indicate greater edema. Change from baseline will be assessed at Weeks 8 and 12; a reduction indicates improvement.
Baseline, Week 8, and Week 12
Change in Pain Intensity
大体时间：Baseline, Week 8, and Week 12
Lower-extremity pain intensity will be assessed using a 100-mm Visual Analog Scale (VAS), with anchors of 0 mm indicating no pain and 100 mm indicating the most severe pain. Higher scores indicate greater pain intensity. Change from baseline will be evaluated at Weeks 8 and 12; a reduction in the score indicates improvement.
Baseline, Week 8, and Week 12
Change in Lower-Extremity Heaviness
大体时间：Baseline, Week 8, and Week 12
Perceived lower-extremity heaviness will be assessed using a 100-mm Visual Analog Scale (VAS), with anchors of 0 mm indicating no heaviness and 100 mm indicating the most severe heaviness. Higher scores indicate greater symptom severity. Change from baseline will be evaluated at Weeks 8 and 12; a reduction in the score indicates improvement.
Baseline, Week 8, and Week 12
Exercise Adherence Rate
大体时间：Throughout the 8-week intervention period.
Exercise adherence will be assessed in the experimental group using daily exercise logs reviewed during weekly telephone calls or text-message follow-ups. An exercise day will be considered completed when the participant reports performing the prescribed home-based program for at least 20 minutes. The adherence rate will be calculated as the number of completed exercise days divided by 40 prescribed exercise days (5 days per week for 8 weeks), multiplied by 100. Values will range from 0% to 100%, with higher percentages indicating greater adherence.
Throughout the 8-week intervention period.
