Ryan S Alcantara, Matthieu B Trudeau, Eric S Rohr
BACKGROUND: The measurement of rearfoot kinematics by placing reflective markers on the shoe heel assumes its motion is identical to the foot's motion. Studies have compared foot and shoe kinematics during running but with conflicting results. The primary purpose of this study was to compare shoe and calcaneus three-dimensional range of motion during running. A secondary purpose was to determine the effect of a less rigid heel counter on tibia motion. RESEARCH QUESTION: Do markers placed on the shoe heel accurately represent calcaneus kinematics during running? METHODS: Three-dimensional coordinate data were collected on 14 subjects (M/F: 9/5) who ran on an instrumented treadmill at 3...

PURPOSE: Neutral lower limb alignment does not necessarily produce a horizontal joint line after total knee arthroplasty (TKA). The orientation of the pre- and postoperative tibial mechanical axes (TMAs-G), tibial component, and joint line relative to the ground were evaluated. METHODS: The study group included 46 knees, 23 posterior-stabilized (PS) and 23 bicruciate-stabilized (BCS) TKAs. Using whole-leg standing radiographs, the static orientation of the pre- and postoperative TMAs-G and the tibial component as well as the postoperative alignment were measured...

When there are politically polarizing events taking place in the world, can it be useful for a therapist to disclose his or her political views within the context of a psychotherapeutic dyad? This paper examines this question through the example of a Marxist therapist working with a politically conservative patient in the polarized political atmosphere following Donald Trump's election to the Presidency of the United States. Also explored are the patient's dynamics that might have made it particularly salient for the therapist to eschew a more neutral stance...

BACKGROUND: Individuals are thought to compensate for femoral anteversion by altering hip rotation. However, the relationship between hip rotation in a neutral position (i.e. static rotation) and dynamic hip rotation is poorly understood, as is the relationship between anteversion and hip rotation. RESEARCH OBJECTIVE: Herein, anteversion and in-vivo hip rotation during standing, walking, and pivoting were measured in eleven asymptomatic, morphologically normal, young adults using three-dimensional computed tomography models and dual fluoroscopy...

BACKGROUND: Nursing Ethics has featured several discussions on what good care comprises and how to achieve good care practices. We should "nurse" ethics by continuously reflecting on the way we "do" ethics, which is what care ethicists have been doing over the past few decades and continue to do so. Ethics is not limited to nursing but extends to all caring professions. In 2011, Elin Martinsen argued in this journal that care should be included as a core concept in medical ethical terminology because of "the harm to which patients may be exposed owing to a lack of care in the clinical encounter," specifically between doctors and patients...

BACKGROUND: Collapse of the medial longitudinal arch and subluxation of the subtalar joint are common occurrences in adult flatfoot deformity. Controversy exists about the role of the tibialis posterior (TP) tendon as first and/or essential lesion. Subtle changes in the foot configuration can occur under weight bearing. PURPOSE: This human cadaveric study is designed to investigate the effect that isolated actuation of the TP tendon has on the medial longitudinal arch and the hindfoot configuration under simulated weight bearing...

OBJECTIVE: The aim of this study was to investigate the effects of normalized muscle tension via tensegrity-based massage on postural stability in a sample of female young adults. METHODS: Nineteen females aged 21.8 ± 1.9 years were recruited presenting abnormal tension at muscles adhering to any of the following structural sites: superior iliac spine, lateral sacropelvic surface, linea aspera at 1/2 of femur length, and superior nuchal line of the occiput. Balance and postural control were assessed during bipedal stance using a force platform in multiple conditions: hard surface or soft foam surface with the head in either a neutral posture or tilted backward...

The human foot and ankle system is equipped with structures that can produce mechanical work through elastic (e.g., Achilles tendon, plantar fascia) or viscoelastic (e.g., heel pad) mechanisms, or by active muscle contractions. Yet, quantifying the work distribution among various subsections of the foot and ankle can be difficult, in large part due to a lack of objective methods for partitioning the forces acting underneath the stance foot. In this study, we deconstructed the mechanical work production during barefoot walking in a segment-by-segment manner (hallux, forefoot, hindfoot, and shank)...

In After God: Morality and Bioethics in a Secular Age, H. Tristram Engelhardt, Jr. explores the broad implications for moral reasoning once a culture has lost a God's-eye perspective. In this paper, I focus on the implications of Engelhardt's views for clinical ethics consultation. I begin by examining the question of whether clinical ethics consultants (CECs) should advocate a particular viewpoint and/or process during consultations or adopt a neutral stance. I then examine the implications of Engelhardt's views for this question...

Alison Clark
The paper argues that writers and psychotherapists are drawn to their work through the desire to remedy an unconscious sense of lack brought about by early relational trauma. Often, because of its origins in psychic pain, the connection between these individuals' beginnings and their profession remains largely dissociated. The theme is developed with reference to the idea of the wounded healer taken up by Jung. It is proposed that the original wound is also the crack that lets the light in: a dissociated tough spirit that can be channelled into discriminating countertransference and strong writing...

PURPOSE: Multiple phenotypes characterized by different disease mechanisms have been hypothesized to explain the large variability in the knee osteoarthritis (KOA) population. The purpose of this study was: to estimate and compare the medial and lateral knee compression forces (CF) during gait of three subgroups of KOA subjects characterized by different alignment and cartilage disruption patterns. METHODS: A secondary data analysis was conducted on a sample of 39 KOA subjects and 18 controls (C)...

A lack of adequate lumbopelvic movement control has been suggested as an underlying mechanism contributing to the development and persistence of low back pain and lower limb pathologies. The purpose of this study was to assess the within and between session reliability (i.e. the ability to discriminate between subjects), and the agreement (i.e. whether scores are identical on repeated measures) of lumbopelvic kinematics in the sagittal plane during functional movement control tasks. Kinematics were measured with a portable inertial measurement unit system...

OBJECTIVE: The longevity of a knee prosthesis is influenced by the wear of the tibial insert due to its posture and movement. In this study, we assumed that the strain on the tibial insert is one of the main reasons for its wear and investigated the influence of the knee varus-valgus angles on the mechanical stress of the tibial insert. METHODS: Knee prosthesis motion was simulated using a knee motion simulator based on a parallel-link six degrees-of-freedom actuator and the principal strain and pressure distribution of the tibial insert were measured...

Sarah R Chang, Rudi Kobetic, Ronald J Triolo
An important consideration in the design of a practical system to restore walking in individuals with spinal cord injury is to minimize metabolic energy demand on the user. In this study, the effects of exoskeletal constraints on metabolic energy expenditure were evaluated in able-bodied volunteers to gain insight into the demands of walking with a hybrid neuroprosthesis after paralysis. The exoskeleton had a hydraulic mechanism to reciprocally couple hip flexion and extension, unlocked hydraulic stance controlled knee mechanisms, and ankles fixed at neutral by ankle-foot orthoses...

This article elaborates on the hazards of spiritual history taking. It provides expert insights to consider before entering the field. In summer 2012, a group of spiritual care experts were invited to discuss the complexity of taking spiritual histories in a manner of hermeneutic circle. Thematic analysis was applied to define the emerging themes. The results demonstrate that taking a spiritual history is a complex and challenging task, requiring a number of personal qualities of the interviewer, such as 'being present', 'not only hearing, but listening', 'understanding the message beyond the words uttered', and 'picking up the words to respond'...

As part of a senior leadership class in an undergraduate baccalaureate nursing program in the northeastern United States, we conducted an experiential, theater-based workshop designed to increase student awareness of the micro-dynamics of power and the enactment of status in their day-to-day lives. These exercises allowed student participants to embody status and power and understand it in ways that they did not after simply completing assigned readings. At the conclusion of the workshop the participants were asked to reflect on their status habits and the consequences of these habits in a single hand-written page...
