Background: Powered ankle-foot prosthetic devices can generate net positive mechanical work during gait, which mimics the physiological ankle. However, gait deviations can persist in individuals with transfemoral limb loss because of habit or lack of rehabilitation. Prosthetic research efforts favor the design or evaluation of prosthetic componentry and rarely incorporate any type of rehabilitation, despite evidence suggesting that it is critical for minimizing gait imbalances.

Introduction: The number of people with lower limb loss continues to grow, though most research to date has been non-committal and lacks the appropriate clinical guidance required for proper prosthetic prescription. Previous literature using traditional spatiotemporal and biomechanical measures has not accurately identified differences in gait patterns when using different prosthetic devices. Therefore, a knowledge gap remains.

Introduction: There is a growing population of women with limb loss, yet limited research is available to provide evidentiary support for clinical decision-making in this demographic. As such, there is a critical gap in knowledge of evidence-based healthcare practices aimed to maximise the physical and psychosocial needs of women with limb loss. The objective of this study is to develop a comprehensive, survey-based needs assessment to determine the unique impact of limb loss on women, including physical and psychosocial needs.

Background: The prescription of prosthetic ankle-foot devices is often based on the professional judgment of the limb loss care team or limited evidentiary research. Current prosthetic research efforts have focused on the design and development of prosthetic devices rather than on understanding which devices are the most appropriate to prescribe. This investigation will evaluate biomechanical, functional, and subjective outcome measures to help determine the optimal prescription parameters of prosthetic ankle-foot devices.

Article Synopsis
  • * Adaptive sports are emerging as effective rehabilitation tools that address the specific needs of these veterans, particularly through activities like kayaking and sailing.
  • * A study assessing the impact of a single day of adaptive sports showed positive improvements in veterans' overall health, quality of life, and social interaction, suggesting that such events are beneficial and should be supported by the Department of Veterans Affairs.

Objective: The purpose of this study was to assess the weight shift and X-Factor values of golfers with lower limb loss.

Design: Veterans with above or below knee limb loss participated in a 3-day adaptive golf event hosted by the Department of Veterans Affairs. Professional golf instructors educated participants on proper golf swing mechanics, after which kinematic analysis of trunk rotation and kinetic analysis of weight transfer between the legs during the golf swing were evaluated using three-dimensional motion capture and force platforms.

Background: Children with cerebral palsy indicate poor continuous gait inter-limb coordination compared to typically developing children. Limited research exists in the understanding of the coordinative relationship between the arms and legs of these children and if the phasing relationships between limbs can be improved.

Research Question: Which motor control factors impact coordination in children with cerebral palsy and can coordination improve with intervention?

Methods: This literature review provides a comprehensive overview of the current knowledge of continuous coordination in a pediatric, pathologic population with an emphasis on inter-limb coordination.

Background: Continuous inter-limb coordination and the ability to offset perturbations to a movement pattern (i.e., stability) are important factors in efficient motor performance.

Motor function difficulties associated with unilateral spastic cerebral palsy (USCP) impact gait inter-limb coordination between the upper and lower extremities. Two motor learning based, upper extremity treatments, Constraint Induced Movement Therapy (CIMT) and Hand Arm Bimanual Therapy (HABIT), have resulted in improvements in coordination and function between the arms in children with USCP. However, no study has investigated whether coordination between the upper and lower extremities improves after either intervention during a functional task, such as walking.

Aim: An approach that simultaneously engages both the upper and lower extremities, hand-arm bimanual intensive therapy including lower extremity (HABIT-ILE), has recently demonstrated improvements in upper and lower extremities in children with unilateral cerebral palsy (CP). It is not known whether children with bilateral CP would benefit from this approach. The aim of this study was to examine the efficacy of HABIT-ILE in children with bilateral CP.

Objective: To assess differences in sagittal plane joint kinematics and ground reaction forces between lean and obese adult dogs of similar sizes at 2 trotting velocities.

Animals: 16 adult dogs.

Procedures: Dogs with body condition score (BCS) of 8 or 9 (obese dogs; n = 8) and dogs with BCS of 4 or 5 (lean dogs; 8) on a 9-point scale were evaluated.

Article Synopsis
  • The text describes a complex surgical technique for total arterial revascularization using both internal thoracic arteries (ITA), emphasizing the use of a T-graft method to connect them.
  • It involves anastomosing the lower segment of the free right ITA to the proximal part of the left in situ ITA, and then connecting the distal segment of the left ITA to the right ITA.
  • The procedure can be done without putting the heart on a pump, which helps prevent any interventions on the ascending aorta.
