Abstract

Objectives

To evaluate physical recovery based on physiological measures of gait economy, gait speed, exertional heart rate, comprehensive high-level activity mobility predictor (CHAMP) and daily step counts over the first 12 months post-percutaneous osseointegrated prosthesis (post-POP).

Design

Prospective longitudinal cohort study.

Setting

Academic hospital.

Participants

Participants (N=10) underwent a unilateral POP implantation from a parent prospective study.

Interventions

Surgery.

Main Outcome Measures

Gait economy, gait speed, exertional heart rate, CHAMP, and daily step counts.

Results

Significant improvement in gait economy, relative to baseline, were observed at 3-month (P=.02), 6-month (P=.02) and 12-month (P<.01) post-POP. Significant increase in CHAMP scores, relative to baseline, were observed at 6-months (P=.01) and 12-months (P<.01) post-POP. Significant increase in exertional heart rate (P<.01), gait speed (P=.03) and daily step count (P=.04), relative to baseline, was observed at 12-months post-POP. The gait economy and CHAMP scores showed earlier gains compared with exertional heart rate, gait speed, and daily step count scores, with the greatest gains observed in the first 3-6 months post-POP.

Conclusions

These data will help to inform expectations for outcomes for patients and clinicians considering POP implantation and could assist in detecting outliers from the normal recovery curve who may benefit from targeted interventions post-POP.

加压贴合经皮骨整合假体在经股截肢术后的身体恢复。

目的：加压贴合经皮骨整合假体（POP）是一种创新的骨锚定假体，与传统的窝悬挂系统相比，在成人经股截肢后安全有效。然而，在评估pop后身体恢复的轨迹方面，研究是有限的。本研究的目的是基于步态经济性、步态速度、运动心率、综合高水平活动能力预测指标（CHAMP）和每日步数等生理指标来评估pop后前12个月的身体恢复情况。设计：前瞻性纵向队列研究。单位：学术医院。参与者：10名参与者接受了来自父母前瞻性研究的单侧POP植入。干预:手术。主要观察指标：步态经济性、步态速度、运动心率、CHAMP和每日步数。结果：与基线相比，在3个月（p=0.02）、6个月（p=0.02）和12个月时，步态经济性有了显著改善。结论：这些数据将有助于告知考虑植入POP的患者和临床医生对结果的预期，并有助于发现正常恢复曲线中的异常值，这些异常值可能会从POP后的针对性干预中受益。

期刊介绍： The Archives of Physical Medicine and Rehabilitation publishes original, peer-reviewed research and clinical reports on important trends and developments in physical medicine and rehabilitation and related fields. This international journal brings researchers and clinicians authoritative information on the therapeutic utilization of physical, behavioral and pharmaceutical agents in providing comprehensive care for individuals with chronic illness and disabilities. Archives began publication in 1920, publishes monthly, and is the official journal of the American Congress of Rehabilitation Medicine. Its papers are cited more often than any other rehabilitation journal.
