EFFECTS OF ADD-ON NÄDÄNUSANDHÄNA ON PSYCHOLOGICAL VARIABLES AND LUNG FUNCTION IN THE REHABILITATION OF SPINAL CORD INJURED INDIVIDUALS: A PILOT STUDY

We hypothesised that Nadanusandhana, a yogic technique of meditation, has an effect on:
1. Psychological variables i.e. depression, stress and anxiety (measured by the DASS 21)
2. Peak Expiratory Flow Rate (PEFR) (measured by a peak flow meter)

Participants:
People with SCI undergoing rehabilitation (n=44) at Swami Vivekananda National Institute of Rehabilitation, Training and Research (SVNIRTAR), Odisha, India

Selection of the Subjects:
Screening using medical records
Consent obtained
Randomisation of the sample into 2 groups [experimental (n=22), control (n=22)]

70 % attendance was required for the participants to be included in post intervention data analysis. Pre data was taken for both groups including DASS 21 score, PEFR and demographic information before the study commenced. Post scores were taken after 1 month of intervention. The participants evaluation tool was done at the start of the second week for the experimental group only.

Findings:
1. A significant improvement was noted in PEFR of the experimental group
2. There was no significant change within groups but a greater mean percentage reduction in Depression, Anxiety and Stress in the yoga/experimental group compared to the control.
3. Weak positive correlation between the mean scores of the Participant Evaluation tool and the DASS 21 mean scores

我们提出假设：作为一种瑜伽冥想技法的纳达努桑达纳（Nadanusandhana）可对以下指标产生影响：
1. 心理变量：即抑郁、压力与焦虑（通过DASS 21量表进行测评）
2. 峰流速（PEFR，通过峰流速仪进行测评）

参与者：
印度奥里萨邦斯瓦米·维韦卡南达国家康复培训与研究所（Swami Vivekananda National Institute of Rehabilitation, Training and Research, SVNIRTAR）内，正在接受康复治疗的脊髓损伤（Spinal Cord Injury, SCI）患者，共计44名。

受试者遴选流程：
通过病历开展筛查→获取知情同意书→将样本随机分为两组：实验组（n=22）与对照组（n=22）。

干预后数据分析仅纳入出勤率不低于70%的受试者。研究启动前，采集两组受试者的基线数据，涵盖DASS 21量表得分、峰流速值及人口统计学信息。干预实施满1个月后，采集两组受试者的后测数据。仅针对实验组，于干预第二周初始阶段完成受试者评估工具的测评。

研究结果：
1. 实验组受试者的峰流速值出现显著改善；
2. 两组组内未观察到显著变化，但相较于对照组，瑜伽/实验组的抑郁、焦虑与压力得分的平均降幅更为显著；
3. 受试者评估工具平均得分与DASS 21平均得分之间存在弱正向相关关系。
