The aim of the present study was to objectively assess the physical activity levels of patients after tumor prosthesis implantation with two objective measurement devices.
The DynaPort ADL monitor permitted up to 24 hr monitoring of lower-extremity physical activities in daily life with respect to posture and locomotion. The step activity monitor (SAM) was worn for a whole week to collect the daily number of gait cycles. The devices were worn during the waking hours by 22 patients with knee prostheses after wide tumor resection.
In the MSTS and TESS scores the patients achieved over 80% of the maximum score indicating a good clinical outcome. The most prominent activity was sitting which accounted for 54 +/- 18% of the recorded time, followed by standing (27 +/- 16%), locomotion (10 +/- 6%), and lying (8 +/- 6%). During locomotion, the average walking activity accumulated to 4,786 +/- 1,770 step cycles per day (range 2,045-8,135) corresponding to a yearly 1.75 million steps. There was no significant correlation between clinical scores and step count measures.
Even though this activity level was lower than for a group of healthy adults it was comparable to the activity level for other patients, for example, with hip arthroplasty as reported in the literature.
本研究的目的是使用两种客观测量设备客观评估肿瘤假体植入术后患者的身体活动水平。
DynaPort日常活动监测仪可对日常生活中下肢关于姿势和运动的身体活动进行长达24小时的监测。步数活动监测仪（SAM）佩戴一整周以收集每日步态周期数。22例广泛肿瘤切除术后行膝关节置换术的患者在清醒时间佩戴这些设备。
在肌肉骨骼肿瘤学会（MSTS）和德州肿瘤假体评分（TESS）中，患者获得了超过80%的最高分，表明临床结果良好。最主要的活动是坐着，占记录时间的54±18%，其次是站立（27±16%）、行走（10±6%）和躺着（8±6%）。在行走过程中，平均每日步行活动累计为4786±1770步周期（范围2045 - 8135），相当于每年175万步。临床评分与步数测量之间无显著相关性。
尽管该活动水平低于一组健康成年人，但与文献报道的其他患者（如髋关节置换术患者）的活动水平相当。
