User needs, prosthetic design priorities, and functional movement assessments for children with above/through-knee limb absence in Cambodia: a mixed methods interactive interview Open
Children were successfully engaged through an interactive interview. Design innovation is required for more stable prosthetic joints with a greater range of motion and appropriate appearance. Identified improvements will increase quality o…
Psychometric properties of the Khmer version of the locomotor capabilities index (LCI-5) for lower-limb prosthesis and orthosis users Open
Background: The unavailability of validated outcome measures in local languages limits the extent to which the impact of prosthetic and orthotic devices can be assessed. Objectives: This study examined the psychometric properties of the Kh…
Growth patterns of lower limbs in children with a traumatic transtibial amputation: A retrospective observational cohort study of anthropometric data from Cambodia Open
Background: The growth dynamics of the amputated limb are currently unknown for children, affecting prosthetic provision and child’s overall wellbeing. Objective: The objective of this study was to investigate the growth patterns of the re…
Levels and determinants of ambulatory mobility in lower-limb prosthesis users from urban and rural Cambodia: a cross-sectional survey study Open
Objectives The majority of people globally who have undergone limb amputations are living in low- and middle-income countries. For those with lower-limb amputations, ambulatory mobility with a prosthesis is considered a key factor for achi…
Evaluation of Device Quality and Satisfaction at Delivery during an Intensive Prosthesis Fitting Camp, and 3-Month Follow-Up Open
Prosthetic limbs enable mobility, independence, and social participation. Fitting camps provide mobility assistive devices to many individuals in intensive sessions, but concerns exist regarding device design, fabrication quality, and the …
Bridging the gap: retrospective clinical casefiles analysis defines the key prosthetic provision challenges for children with a major lower limb absence in Cambodia Open
The impact of growth on paediatric prosthetic provision has been quantified for children with different amputation levels. Findings provide insight to manufacturers of prosthetic components on durability considerations. Results provide cla…
Understanding maintenance, repair, and replacement of prosthetic limbs using routinely-collected data: a retrospective study over three decades in Cambodia Open
Prosthetic limb maintenance, repair, and replacement are influenced both by the device's durability and the user's access to well-resourced physical rehabilitation services. A device that is worn-out and repaired or replaced early may indi…
Listening to children with lower limb loss: Rationale, design, and protocol for delivery of a novel globally applicable research toolkit—Prosthetic user needs, quality of life, pain, and physical function Open
Introduction Rehabilitation after childhood lower limb loss is complex and dependent on multiple stakeholders and environmental factors. While research with adults underscores the importance of involving prosthetic limb users and caregiver…
Understanding repair and replacement of prosthetic limbs using routinely-collected data: a retrospective study over three decades in Cambodia Open
Prosthetic limbs deliver major quality of life and socioeconomic benefits for people with amputation, particularly in low-resource settings. The value of administrative data analysis to enable sustainable health care improvement is establi…
Gait Performance of Friction-Based Prosthetic Knee Joint Swing-Phase Controllers in Under-Resourced Settings Open
Gait quality can influence walking ability and mobility outcomes making it an important part of prosthetic rehabilitation. Prosthetic knee joint designs can influence gait quality, and limited data exists to guide component selection in un…
