TLDR
A weakness in the posterior compartment muscles of the hip and calf is identified as being the key factor underlying the PAD gait adaptations and may lead to novel, gait-specific treatments.About:

Gait variability is altered in patients with peripheral arterial disease
Sara A. Myers,Jason M. Johanning,Jason M. Johanning,Nicholas Stergiou,Rolando Celis,Leon Robinson,Iraklis I. Pipinos,Iraklis I. Pipinos +7 more
TL;DR: Symptomatic PAD patients have increased gait variability at the ankle, knee, and hip joints at baseline ambulation in the absence of claudication pain, indicating significant baseline deterioration in the locomotor system of symptomatic P AD patients.

Abnormal joint powers before and after the onset of claudication symptoms.
Panagiotis Koutakis,Jason M. Johanning,Gleb Haynatzki,Sara A. Myers,Nicholas Stergiou,G. Matthew Longo,Iraklis I. Pipinos +6 more
TL;DR: In this paper, the authors evaluated patients with bilateral lower limb claudication and characterized their gait abnormality based on advanced biomechanical analysis using joint torques and powers.
Journal ArticleDOI
The influence of stride-length on plantar foot-pressures and joint moments
TL;DR: The results showed that a change in stride lengths alters both, joint moments and foot pressures with clinically interesting indications.
Journal ArticleDOI
Joint torques and powers are reduced during ambulation for both limbs in patients with unilateral claudication
Panagiotis Koutakis,Iraklis I. Pipinos,Sara A. Myers,Nicholas Stergiou,Thomas G. Lynch,Jason M. Johanning +5 more
TL;DR: Overall, the data demonstrate significantly reduced ankle plantar flexion torque and power during late stance with reduced knee power during early and mid stance for the affected limb.
Journal ArticleDOI
The effect of claudication pain on temporal and spatial gait measures during self-paced ambulation
TL;DR: Claudication pain slows ambulatory velocity at preferred and rapid paces, and increases asymmetry when ambulatory function is challenged with rapid walking.

Biomechanics and Motor Control of Human Movement
TL;DR: The Fourth Edition of Biomechanics as an Interdiscipline: A Review of the Fourth Edition focuses on biomechanical Electromyography, with a focus on the relationship between Electromyogram and Biomechinical Variables.
Journal ArticleDOI
Contributions of the individual ankle plantar flexors to support, forward progression and swing initiation during walking.
TL;DR: In this study, the individual contributions of the ankle plantar flexors to the body segment energetics are examined using a musculoskeletal model and optimization framework to generate a forward dynamics simulation of normal walking at 1.5 m/s.
Journal ArticleDOI
Peripheral arterial disease
TL;DR: Interventions such as balloon angioplasty, stenting, and surgical revascularisation should be considered in patients with so-called "critical limb ischaemia", dependent on the anatomy of the stenotic or occlusive lesion.
Journal ArticleDOI
Gait characteristics of patients with knee osteoarthritis.
TL;DR: Objective gait analysis can be used to document gait adaptations used by patients with knee OA and the female subjects had significantly greater knee flexion and a greater knee extensor moment.

TL;DR: Results of the current study should motivate future experimental trials of specific hip flexor stretching and ankle plantarflexor concentric strengthening exercises to preserve and potentially improve walking performance in the elderly.
