Increasing levels of physical activity (PA) and aerobic fitness can reduce non-specific chronic low back pain (NSCLBP) yet patient's PA and aerobic fitness have been shown to be lower than healthy counterparts. Pedometers are effective at promoting PA, yet more advanced consumer level activity monitors (AAMs) can provide greater feedback to the user. The aim of this study was to determine the effect of new advances in commercially available wearable technology on PA, aerobic fitness and disability of low back pain participants.
Seventeen participants volunteered and were provided with Fitbit Charge HR (FIT N.=9) or pedometer (PED N.=8). Participants completed a 6-week, multi-component, PA programme lasting two hours per week. All activities were designed to be relevant to activities of daily living.
Non-significant (P>0.05) increases in step count were identified from pre- to postintervention in both FIT, (23%) and PED (29%) groups. At one month follow-up, aerobic fitness significantly (P<0.05) increased by 33% in the FIT but not PED group. Non-significant reductions in both FIT (19%) and PED (13%) disability scores were identified and remained stable at one-month follow-up. No significant change in body composition were reported for either group (P>0.05).
Our data suggest feedback on user exercise intensity provided by AAMs, may show promise in improving aerobic fitness. AAMs were not more effective than pedometers at increasing the volume of PA, or reducing disability in NSCLP participants.
增加身体活动（PA）水平和有氧适能可减轻非特异性慢性下腰痛（NSCLBP），但患者的PA和有氧适能低于健康对照者。计步器可有效促进PA，但更先进的消费级活动监测器（AAM）能为用户提供更多反馈。本研究旨在确定市售可穿戴技术的新进展对下腰痛参与者的PA、有氧适能和功能障碍的影响。
17名参与者自愿参加，被给予Fitbit Charge HR（FIT组，n = 9）或计步器（PED组，n = 8）。参与者完成了一项为期6周、每周两小时的多成分PA计划。所有活动均设计为与日常生活活动相关。
FIT组（23%）和PED组（29%）干预前后步数增加均无统计学意义（P>0.05）。在1个月随访时，FIT组有氧适能显著增加（P<0.05）33%，而PED组未增加。FIT组（19%）和PED组（13%）功能障碍评分均有非显著降低，且在1个月随访时保持稳定。两组身体成分均无显著变化（P>0.05）。
我们的数据表明，AAM提供的关于用户运动强度的反馈可能有望改善有氧适能。在增加PA量或降低NSCLP参与者功能障碍方面，AAM并不比计步器更有效。
