Objective. To evaluate a new treadmill test, determining pain threshold speed (PTS) for use in assessment and measuring rehabilitation of patients with intermittent claudication. Methods and design. Twenty-nine patients with claudication were evaluated, and the ankle-brachial index (ABI) was assessed. PTS was determined with a treadmill protocol based on level walking, low starting speed, and progressive increments at a predetermined distance up to the onset of pain. Repeatability and equivalence with a time-based protocol were verified. PTS was compared to pain free walking distance, 6-minute walking distance, and ABI. Results. PTS was measured in all patients (3.6 +/- 1.1 km/h). Repeatability and equivalence between established tests were demonstrated. PTS showed a significant correlation with pain free walking distance (r = 0.833; P = 0.0001), with 6-minute walking distance (r = 0.724; P = 0.005), and with ABI in the more ischemic limb (r = 0.641; P = 0.0001). Conclusions. PTS is a reliable parameter that correlates well with other established measures. It is useful for determining the degree of functional handicap and for designing and guiding rehabilitation protocols.

Abstract

Objective. To evaluate a new treadmill test, determining pain threshold speed (PTS) for use in assessment and measuring rehabilitation of patients with intermittent claudication. Methods and design. Twenty-nine patients with claudication were evaluated, and the ankle-brachial index (ABI) was assessed. PTS was determined with a treadmill protocol based on level walking, low starting speed, and progressive increments at a predetermined distance up to the onset of pain. Repeatability and equivalence with a time-based protocol were verified. PTS was compared to pain free walking distance, 6-minute walking distance, and ABI. Results. PTS was measured in all patients (3.6 +/- 1.1 km/h). Repeatability and equivalence between established tests were demonstrated. PTS showed a significant correlation with pain free walking distance (r = 0.833; P = 0.0001), with 6-minute walking distance (r = 0.724; P = 0.005), and with ABI in the more ischemic limb (r = 0.641; P = 0.0001). Conclusions. PTS is a reliable parameter that correlates well with other established measures. It is useful for determining the degree of functional handicap and for designing and guiding rehabilitation protocols.
