Objectives of Study:

Primary Research Objective: For stroke patients with sarcopenia classified as Brunnstrom stages I-III, to investigate whether nutritional supplementation combined with contralateral exercise intervention (comprehensive intervention group) can more effectively improve patients' muscle status (Appendicular Skeletal Muscle mass Index, ASMI) compared to nutritional supplementation alone (nutrition group). Secondary Research Objectives: For stroke patients with sarcopenia classified as Brunnstrom stages I-III, to explore whether nutritional supplementation combined with exercise intervention can more effectively improve patients' nutritional status: Body Mass Index (BMI), handgrip strength, and Five-Times-Sit-to-Stand Test (FTSST); and stroke-related functions: National Institute of Health Stroke Scale (NIHSS) score, Mini-Mental State Examination (MMSE) score, Fugl-Meyer Assessment (FMA) score, brain function [measured by functional Near-Infrared Spectroscopy (fNIRS) to analyze oxygenated hemoglobin levels and functional connectivity], and activities of daily living (Modified Barthel Index, MBI) score.

指标中文名:

四肢骨骼肌质量指数

指标类型:

主要指标

Outcome:

The Appendicular Skeletal Muscle Index

Type:

Primary indicator

测量时间点:

1 天、4 周和 8 周

测量方法:

肢体骨骼肌指数(ASMI)是通过使用双能 X 射线吸收测定法(DXA)进行全身扫描来测量的,以量化双臂和双腿的骨骼肌质量(单位:千克)。计算公式为 ASMI = (肢体骨骼肌质量)/(身高2,单位:平方米)。该指标用于诊断肌少症,根据《中国老年肌少症预防干预专家共识》(2023 年),通常采用的亚洲阈值男性为<7.0 kg/m2,女性为<5.4 kg/m2。

Measure time point of outcome:

1day, 4 weeks, and 8 weeks

Measure method:

The Appendicular Skeletal Muscle Index (ASMI) is measured by performing a full-body scan using dual-energy X-ray absorptiometry (DXA) to quantify the skeletal muscle mass in both arms and legs (in kg). It is calculated as ASMI = (appendicular skeletal muscle mass) / (height2, in m2). This metric is used for diagnosing sarcopenia, with commonly adopted Asian thresholds being <7.0 kg/m2 for men and <5.4 kg/m2 for women, based on the Chinese Expert Consensus on Prevention and Intervention of Sarcop

指标中文名:

体重指数

指标类型:

次要指标

Outcome:

Body Mass Index

Type:

Secondary indicator

测量时间点:

1 天、4 周和 8 周

测量方法:

身体质量指数(BMI)是通过体重(千克)除以身高(米)的平方计算得出的,公式为 BMI=体重/(身高2)。它用于评估体重状况,世界卫生组织标准定义如下:体重不足(<18.5)、正常(18.5–24.9)、超重(25–29.9)和肥胖(≥30);中国成人标准将这些调整为:体重不足(<18.5)、正常(18.5–23.9)、超重(24–27.9)和肥胖(≥28)。

Measure time point of outcome:

1day, 4 weeks, and 8 weeks

Measure method:

Body Mass Index (BMI) is calculated by dividing weight (in kg) by the square of height (in m), using the formula BMI = weight / (height2). It is used to assess weight status, with WHO standards defining: underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30); Chinese adult criteria adjust these to: underweight (<18.5), normal (18.5–23.9), overweight (24–27.9), and obese (≥28).

指标中文名:

健侧肌肉握力

指标类型:

次要指标

Outcome:

Grip strength of the unaffected side muscles

Type:

Secondary indicator

测量时间点:

1 天、4 周和 8 周

测量方法:

肌肉握力通过手持式测力计进行测量。受试者站立或坐着,手臂自然下垂,肘部呈 90 度。调整握距后,用最大力量握紧设备两次,记录最佳读数(单位:千克)。这一指标反映上肢力量和整体营养状况。亚洲老年人常见的肌少症筛查阈值男性为<28 千克,女性为<18 千克(基于 AWGS 2019 共识)。

Measure time point of outcome:

1day, 4 weeks, and 8 weeks

Measure method:

Muscle grip strength is measured using a handheld dynamometer. The participant stands or sits with the arm naturally and the elbow at 90 degrees. After adjusting the grip span, they squeeze the device twice with maximum force, and the best reading (in kg) is recorded. This metric reflects upper limb strength and overall nutritional status. Common sarcopenia screening thresholds for Asian older adults are <28 kg for men and <18 kg (based on AWGS 2019 consensus)

五次坐站测试

指标类型:

次要指标

Outcome:

The Five Times Sit-to-Stand Test

Type:

Secondary indicator

测量时间点:

1 天、4 周和 8 周

测量方法:

五次坐站测试是通过让参与者坐在大约 43-45 厘米高的椅子上,双臂交叉胸前,然后尽可能快地完成五个完整的站坐循环来测量的。从开始到第五次完全站立的总时间(以秒为单位)被记录下来。这项测试评估下肢力量、平衡和跌倒风险;常见标准表明,健康的老年人通常在≤12 秒内完成,而超过 12-15 秒的时间则表明功能衰退或跌倒风险增加。

Measure time point of outcome:

1day, 4 weeks, and 8 weeks

Measure method:

The Five Times Sit-to-Stand Test is measured by having the participant sit on a chair approximately 43–45 cm high with arms crossed against the chest, then complete five full stand-sit cycles as quickly as possible. The total time (in seconds) from the start until fully standing for the fifth time is recorded. This test assesses lower limb strength, balance, and fall risk; common standards indicate that healthy older adults typically complete it in ≤12 seconds, while times exceeding 12–15 second

The data management in this study strictly adhered to the protocol requirements. Data collection was performed using paper-based case report forms (CRFs) for original records. All data were accurately and diligently completed by researchers as required, and once entered, the content was not to be altered lightly. If corrections were necessary, an additional narrative method was employed, requiring the signature and date of the responsible research physician to ensure data traceability. After data entry into the electronic database, a query and modification process was implemented to guarantee data reliability. The final locked database was used for statistical analysis, which was conducted using SAS 9.4 software. All computers utilized for data collection and management were password-protected and regularly backed up to ensure data security.
