Polestriding Versus Walking for Subjects With Poor Leg Circulation

• Length of Exercise Duration on the Treadmill Constant Work Rate Exercise Test [ Time Frame: Baseline and 24 weeks ] [ Designated as safety issue: No ]
  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).
  
  

• Onset of Claudication Pain During Constant Work Rate Treadmill Test [ Time Frame: At 24 weeks ] [ Designated as safety issue: No ]
  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.
  
  

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.
