The purpose of this study is to compare the effects of polestriding (walking with poles) and traditional walking on physical endurance in subjects with poor circulation in their legs. Another goal is to evaluate the effectiveness of a walking program in increasing the amount of oxygen in the calf muscles and therefore improving overall physical activity and quality of life.

Condition Intervention Phase
Peripheral Arterial Disease Behavioral: Walking with poles Behavioral: Walking exercise Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Polestriding Versus Walking for PAD Rehabilitation

Primary Outcome Measures:
  • Length of Exercise Duration on the Treadmill Constant Work Rate Exercise Test [ Time Frame: Baseline and 24 weeks ]
    Patients walked on the CWR test at 85% of his/her peak VO2 on the baseline progressive treadmill test. Since the polewalking group was older than the walking group, subject age was entered into the analysis as a co-variate. Intent-to-treat (ITT) analyses were used. The last measurement taken for all subjects with at least one follow-up test was carried forward (n=97).

Secondary Outcome Measures:
  • Onset of Claudication Pain During Constant Work Rate Treadmill Test [ Time Frame: At 24 weeks ]
    Perceived pain onset was recorded during the constant workrate test using the Borg ratio scale. Patient rated their pain from 0-10. Time elapased on the treadmill (minutes) at the onset of pain was recorded.

Enrollment: 146

Study Completion Date: May 2011
Primary Completion Date: May 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Walking with Poles
Patients were assigned to a 24 week walking with poles program of rehabilitation. The intervention was the additional of poles to the walking program.
Behavioral: Walking with poles
Patients walked with poles, 20-45 minutes, 3 times/week for 24 weeks.
Other Name: Exercise
Active Comparator: Traditional walking program
Patients were assigned to a 24 week traditional walking program.
Behavioral: Walking exercise
Patients walked for 20-45 minutes, 3 times/week for 24 weeks.
Other Name: Exercise

Detailed Description:

Peripheral Arterial Disease (PAD/PVD) is caused by decreased blood flow to the legs. The most common symptom is intermittent claudication pain during walking that is relieved by rest. Walking is the primary treatment prescribed for PAD rehabilitation. Polestriding uses muscles of the upper and lower body in a continuous movement. Walking with poles increases stride length, cadence and walking speed and decreases ground reaction forces on the joints. Subjects in this study will participate in a walking program with or without poles.

Dr. Collins' research focuses on physical activity interventions to improve the functional status of persons with chronic illness. Several rehabilitation studies have tested the efficacy of walking exercise for patients with PAD. Studies on polestriding indicate that it may be superior to traditional walking, but these two methods have never been compared. Approximately 30% of patients with coronary artery disease have PAD as their only symptom. As the population ages and more people are affected by this debilitating condition, nurse-initiated rehabilitative therapies, such as polestriding, need to be explored. The consent form explains the purpose of the study in addition to the procedures, risks, benefits, options, confidentiality, costs, and compensation. Participants are also asked to sign a HIPPA authorization.
