背景情况:
- 住院的老年人经常体验到身体功能和认知能力的下降.
- 众所周知,抵抗训练 (RT) 可以改善老年人群的健康状况.
- 结合身体和认知挑战的双任务训练可能会带来独特的好处.
研究的目的:
- 研究一项为期12周的双重任务耐力训练 (RT) 计划对住院老年人的身体功能,认知能力以及氧化应激和慢性炎症的生物标志物的影响.
- 为了评估这些影响在随后的脱期后的持续性.
主要方法:
- 11名住院的老年人 (平均年龄为83.09±8.1岁) 参与了一项为期42周的研究.
- 12周的双重任务RT干预 (16至27周) 之前是基线期,之后是脱训期 (29至41周).
- 评估包括身体功能测试,认知能力测量和氧化应激和炎症的血液生物标志物.
主要成果:
- 与基线相比,双任务RT显著改善了平衡和4米步行速度.

Restorative Care
1.9K
Restorative care is provided once a patient has been discharged from a healthcare facility and requires additional services. The additional services include home care, rehabilitation programs, and extended care. Restorative care centers help the patient regain their previous level of functioning or acquire a new level of functioning due to the incapacitating effects of a disease or a disability. It aims to assist patients in enhancing their quality of life by encouraging independence,...
