Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation01:21

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

537
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Peripheral Artery Disease III: Interprofessional Care

443
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...

Peripheral Artery Disease I: Introduction

496
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Peripheral Artery Disease IV: Nursing Management

499
 The nursing management of a patient with peripheral artery disease (PAD) begins with a thorough assessment of the patient’s health history and clinical manifestations.AssessmentHealth History: Evaluate the patient’s history of hypertension, hyperlipidemia, family history of cardiovascular issues, and lifestyle factors such as dietary patterns, smoking, and physical activity.Physical Examination:Assess the affected extremity for decreased or absent peripheral pulses,...

Summary

Patients with intermittent claudication (IC) exhibit altered walking patterns, characterized by slower speeds and prolonged flat foot phases. These gait changes, even before pain onset, may help increase blood flow to leg muscles.

Area of Science:

  • Biomechanics
  • Human locomotion
  • Vascular medicine

Background:

  • Patients with intermittent claudication (IC) walk slower and use more oxygen than healthy individuals.
  • An inefficient gait pattern is suspected but not well-characterized in IC.

Purpose of the Study:

  • To compare gait parameters in newly diagnosed intermittent claudication patients versus healthy controls.
  • To identify specific spatiotemporal gait alterations in IC.

Main Methods:

  • Cross-sectional study comparing 28 IC patients and 28 controls.
  • Used photoelectric gait analysis (OptoGait) to measure spatiotemporal parameters.
  • Gait assessed during pain-free and painful treadmill walking at self-selected pace.

Main Results:

  • IC patients walked 27% slower with shorter steps and lower cadence.
  • IC patients showed prolonged stance and double support phases, even pre-pain.
  • A key finding was a 17% longer flat foot phase during painful walking.

Conclusions:

  • Intermittent claudication patients display a distinct altered gait pattern compared to controls.
  • Prolonged flat foot duration during stance may enhance muscle blood flow.
  • Gait alterations in IC involve both reduced propulsion and increased relaxation phases.
