Physical Therapy Practice Patterns for Military Service Members with Lower Limb Loss

Abstract Introduction Military service members with limb loss have unrestricted access to physical therapy (PT) services. Identifying PT interventions used based on clinical rationale and patient needs/goals can provide insight towards developing best practice guidelines. The purpose of this study was to identify preferred PT practice patterns for military service members with lower limb loss. Materials and Methods This was a retrospective cohort study and was approved by the Naval Health Research Center (NHRC) Institutional Review Board. Data for 495 service members with lower limb loss was analyzed. Frequency of PT visits and units of treatment received were quantified in 3-month increments during the first year after injury and compared for individuals with unilateral limb loss distal to the knee (DIST), unilateral limb loss proximal to the knee (PROX), and bilateral limb loss (BILAT). Results A total of 86,145 encounters occurred during the first year after injury. Active treatments were included in 94.0% of all treatments, followed by manual therapy (15.1%), patient education (11.5%) and modalities (2.4%). The highest number of encounters, consisting of active and manual therapy, was received by the DIST group within the first 3 months, while after the first 3 months, the BILAT group had higher encounters and received more active and manual therapy. Utilization of patient education was higher in the PROX and BILAT groups compared to the DIST group throughout the first year after injury. Conclusions Service members with limb loss utilize PT services often within the first year after injury. Trends of PT practice are most likely influenced by comorbidities and healing time variance between levels of amputation.
