The HiBalance program is a progressive and highly challenging balance training intervention incorporating Parkinson’s disease (PD) specific balance components. The program improves balance and gait and increases the amount of ambulation in short-term, in older adults with PD. Yet, potential short- and long-term effects on habitual physical activity and sedentary behavior are currently unidentified. The aim of this study was to conduct preplanned secondary analyses of short- and long-term effects of the HiBalance program on objectively measured amount and bouts of brisk walking, sedentary behavior, and total physical activity in older adults with PD. Further, our aim was to investigate demographic, intervention-related, disease-related, and function-related factors potentially related to a difference in activity after intervention. A total of 100 older adults with mild-moderate PD were recruited. The intervention group participated in the HiBalance program, and the control received care as usual and was offered the HiBalance program after study termination. Physical activity data were collected using accelerometers at baseline, after intervention and after 6 and 12 months. A multilevel model was utilized to investigate the postintervention and long-term (6 and 12 months) effects on total physical activity, amount and bouts of brisk walking (i.e., moderate intensity physical activity), and sedentary behavior. Between-group difference for the main outcome brisk walking was at postintervention: Δ −10, CI −23.78 to 3.69 min/day (); 6 months: Δ −10, CI −23.89 to 3.89 min/day (); and 12 months: Δ −4, CI −16.81 to 8.81 min/day (). Being part of the intervention group as well as finishing training during spring/summer showed an independent association to increased brisk walking after the intervention period. In conclusion, the HiBalance program increases the physical activity on moderate intensity after intervention and at 6 months but not at 12 months, independently of improved balance. Season seems to influence the effect on the physical activity.

平衡训练对帕金森氏病老年人的习惯体育活动的长期影响。

HiBalance计划是一项渐进且极富挑战性的平衡训练干预措施，结合了帕金森氏病（PD）的特定平衡成分。该程序可改善患有PD的老年人的短期平衡和步态，并增加他们的下肢活动量。然而，目前尚不清楚对习惯性体育锻炼和久坐行为的短期和长期影响。这项研究的目的是对HiBalance计划对客观测量的PD老年人的快走，久坐行为和总体体育活动的数量和发作进行短期和长期影响的预计划的二级分析。此外，我们的目的是调查可能与干预后活动差异相关的人口统计学，干预相关，疾病相关和功能相关因素。总共招募了100名中度PD患者。干预组参加了HiBalance计划，对照组照常接受护理，并在研究终止后获得了HiBalance计划。在基线，干预后以及6和12个月后，使用加速度计收集身体活动数据。采用多层次模型研究干预后和长期（6和12个月）对总体体育活动，快走的次数和次数（即中等强度的体育活动）以及久坐行为的影响。干预后主要结局轻快行走的组间差异为Δ-10，CI -23.78至3.69 min / day（对照组照常接受护理，并在研究终止后提供HiBalance程序。在基线，干预后以及6和12个月后，使用加速度计收集身体活动数据。采用多层次模型研究干预后和长期（6和12个月）对总体体育活动，快走的次数和次数（即中等强度的体育活动）以及久坐行为的影响。干预后主要结局轻快行走的组间差异为Δ-10，CI -23.78至3.69 min / day（对照组照常接受护理，并在研究终止后提供HiBalance程序。在基线，干预后以及6和12个月后，使用加速度计收集身体活动数据。采用多层次模型研究干预后和长期（6和12个月）对总体体育活动，快走的次数和次数（即中等强度的体育活动）以及久坐行为的影响。干预后主要结局轻快行走的组间差异为Δ-10，CI -23.78至3.69 min / day（采用多层次模型研究干预后和长期（6和12个月）对总体体育活动，快走的次数和次数（即中等强度的体育活动）以及久坐行为的影响。干预后主要结局轻快行走的组间差异为Δ-10，CI -23.78至3.69 min / day（采用多层次模型研究干预后和长期（6和12个月）对总体体育活动，快走的次数和次数（即中等强度的体育活动）以及久坐行为的影响。干预后主要结局轻快行走的组间差异为Δ-10，CI -23.78至3.69 min / day（）; 6个月：Δ-10，CI -23.89至3.89 min / day（）；和12个月：Δ-4，CI -16.81至8.81分钟/天（）。作为干预组的一部分，并在春季/夏季完成培训，显示出干预期过后，增加轻快步行的独立关联。总之，HiBalance计划在干预后和6个月而不是12个月时以中等强度增加身体活动，而与平衡能力改善无关。季节似乎会影响身体活动。
