Individuals with a history of anterior cruciate ligament reconstruction (ACLR) demonstrate persistent reductions in physical activity (PA) volume that are not being addressed during rehabilitation. Currently, it is challenging for clinicians to prescribe exercise interventions that extend beyond in-person rehabilitative care in a manner that is responsive and acceptable to patients.
To investigate the feasibility of using a novel, technology-driven, personalized goal-setting intervention over a 2-month period among young individuals with a history of primary unilateral ACLR.
Single-blinded feasibility study.
University community.
Ten women and 2 men (age = 22.0 ± 3.0 years, time since surgery = 56.0 ± 36.3 months) with a history of primary unilateral ACLR.
INTERVENTION(S): All participants completed a 28-day PA observation period immediately followed by a 28-day individualized PA goal-setting intervention period delivered via a commercially available PA monitor.
MAIN OUTCOME MEASURE(S): Primary feasibility outcomes were days of PA monitor wear compliance and days of goal achievement during the intervention period. Participants also completed the Knee Osteoarthritis Outcome Score (KOOS) at study enrollment and after the intervention period, and the individual change in the KOOS Quality of Life subscale was compared with the minimal detectable change (7.2 points).
Average PA monitor wear compliance was 95.5% ± 7.3% during the observation period and 97.7% ± 2.9% during the intervention period. Median goal achievement was 31.5% ± 6.8% during the intervention period. Five participants demonstrated meaningful improvements in the KOOS Quality of Life subscale during the study period.
Individualized goal setting via mobile technology appears to be a feasible approach to PA promotion. However, based on the low rate of daily goal attainment during the intervention period, continued refinement of this intervention aproach would be beneficial before broad clinical implementation.
有前交叉韧带重建（ACLR）病史的个体表现出持续减少的体力活动（PA）量，而这些问题在康复过程中并未得到解决。目前，临床医生很难为患者开出超出康复治疗范围的运动干预措施，且这些措施要具有响应性和可接受性。
在有单侧 ACLR 病史的年轻个体中，研究使用新型、基于技术的个性化目标设定干预措施在 2 个月期间的可行性。
单盲可行性研究。
大学社区。
10 名女性和 2 名男性（年龄=22.0±3.0 岁，手术时间=56.0±36.3 个月），均有单侧 ACLR 病史。
所有参与者均完成 28 天的 PA 观察期，随后立即进行 28 天的个体化 PA 目标设定干预期，通过商业可用的 PA 监测器进行干预。
主要可行性结果为 PA 监测器佩戴依从性天数和干预期间目标达成天数。参与者还在研究入组时和干预后完成了膝关节骨关节炎结局评分（KOOS），并将 KOOS 生活质量子量表的个体变化与最小可检测变化（7.2 分）进行了比较。
观察期内 PA 监测器佩戴依从率平均为 95.5%±7.3%，干预期内为 97.7%±2.9%。干预期间的中位目标达成率为 31.5%±6.8%。在研究期间，有 5 名参与者的 KOOS 生活质量子量表有明显改善。
通过移动技术进行个性化目标设定似乎是促进 PA 的一种可行方法。然而，基于干预期间每日目标达成率较低，在广泛临床实施之前，需要对这种干预方法进行进一步改进。
