Patient Prefer Adherence. 2008 Feb 2;2:107-13.
This study evaluated adherence and progression with a 12-week resistance training program amongst a sample of older adults recovering in hospital from lower limb fragility fracture. Forty-nine participants (mean age 84 years) commenced the resistance training program seven days after the injury. The exercise prescription involved training of the hip and knee extensors, hip abductors, and ankle plantar- and dorsi flexors using resistive bands. Exercise sessions were completed tri-weekly for six weeks under supervision by a physiotherapist and tri-weekly for an additional six weeks independently. Adherence was assessed as the proportion of exercise sessions completed of those prescribed and any progression in resistance was documented. Level of adherence was not found to be influenced by age, gender, cognition or strength but was greater amongst those admitted from the community setting and for the first six weeks when supervision was present. Participants were able to obtain similar levels of resistance for the injured side compared to the noninjured side for all exercises excluding hip abduction and those admitted from the community setting achieved higher levels of resistance compared to those admitted from the residential care setting. These findings suggest that an early resistance training program is feasible and well tolerated amongst older adults recovering from lower limb fragility fracture. Further work is necessary to determine how this level of resistance training translates into functional improvements and how to improve adherence levels in clinical rehabilitation settings.
本研究评估了在下肢脆性骨折后于医院康复的老年人群样本中,一项为期12周的阻力训练计划的依从性和进展情况。49名参与者(平均年龄84岁)在受伤7天后开始了阻力训练计划。运动处方包括使用弹力带对髋部和膝部伸肌、髋部外展肌以及踝关节跖屈肌和背屈肌进行训练。在物理治疗师的监督下,每三周进行一次为期六周的训练课程,之后再独立进行为期六周、每三周一次的训练。依从性通过完成的训练课程占规定课程的比例来评估,并记录阻力的任何进展情况。研究发现,依从性水平不受年龄、性别、认知或力量的影响,但在来自社区环境的参与者以及有监督的前六周中,依从性更高。除了髋部外展运动,在所有运动中,参与者受伤侧获得的阻力水平与未受伤侧相似;与来自机构护理环境的参与者相比,来自社区环境的参与者达到了更高的阻力水平。这些发现表明,早期阻力训练计划对于从下肢脆性骨折中康复的老年人是可行的,并且耐受性良好。有必要进一步开展工作,以确定这种阻力训练水平如何转化为功能改善,以及如何在临床康复环境中提高依从性水平。
