Peripheral Artery Disease III: Interprofessional Care01:27

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Summary

Strength training (ST) improves walking capacity and reduces pain in patients with intermittent claudication (IC), offering similar functional benefits to walking training (WT). This suggests ST is a viable exercise option for managing IC symptoms.

Area of Science:

  • Exercise Physiology
  • Rehabilitation Medicine
  • Vascular Medicine

Background:

  • Intermittent claudication (IC) is a common manifestation of peripheral artery disease (PAD), characterized by ischemic leg pain during exercise.
  • Impaired walking capacity significantly impacts the quality of life for individuals with IC.
  • Current rehabilitation often focuses on walking training (WT), but alternative exercise modalities warrant investigation.

Purpose of the Study:

  • To compare the effects of strength training (ST) versus traditional walking training (WT) on walking capacity in patients with IC.
  • To evaluate secondary outcomes including cardiorespiratory fitness, ischemic pain, and muscle strength.

Main Methods:

  • A randomized controlled trial involving 30 patients with IC.
  • Participants were assigned to either ST (whole-body exercises) or WT (intermittent walking) for 12 weeks, training twice weekly.
  • Outcome measures included walking distances, peak oxygen consumption (VO2), and knee extension strength.

Main Results:

  • Both ST and WT significantly improved initial claudication distance, total walking distance, and VO2 at the first treadmill stage.
  • ST led to significant increases in knee extension strength, which correlated with improvements in walking distance.
  • Patients undergoing ST reported significantly lower pain levels compared to those in the WT group.

Conclusions:

  • Strength training is an effective alternative to walking training for improving functional limitations in patients with intermittent claudication.
  • The reduced pain experienced during ST makes it a potentially more tolerable and beneficial exercise modality for this population.
  • ST should be considered as a therapeutic option in the comprehensive management of intermittent claudication.
