Abstract

Post-stroke rehabilitation often involves improving muscle strength and motor function to enhance the quality of life for stroke survivors. Proprioceptive Neuromuscular Facilitation (PNF) has emerged as an effective therapy in this context, particularly in enhancing muscle strength and upper limb function. PNF techniques use specific patterns of movement to activate proprioceptors and improve muscle coordination, which may aid in recovery for stroke patients. Despite its potential, limited research has evaluated its impact on muscle strength improvement, making this study significant.Research Objective: The primary aim of this study was to assess the effectiveness of Proprioceptive Neuromuscular Facilitation (PNF) in improving muscle strength in post-stroke patients, with a focus on the upper limbs. The research was conducted to evaluate the pre-test and post-test muscle strength scores, and to analyze the impact of PNF on muscle strength recovery.Research Methods: This research employed a pre-experimental design with a one-group pre-post test. A sample of 34 post-stroke patients was selected using purposive sampling from the Merdeka Health Center and 1 Ulu Palembang, South Sumatra, Indonesia. The intervention consisted of PNF exercises conducted three times a week for three months. Muscle strength was measured using a hand dynamometer both before and after the intervention. Statistical analysis using Cohen’s d and paired t-tests was performed to evaluate the effectiveness of the intervention.Results: The results revealed a significant improvement in muscle strength after PNF intervention. The mean muscle strength score increased from 2.50 ± 0.570 (pre-test) to 3.64 ± 0.570 (post-test), with a difference of 1.14 ± 0.570. Cohen’s d coefficient of 2 indicated a large effect size, confirming substantial improvement. The paired t-test yielded a p-value of 0.001, demonstrating that the changes were statistically significant.Conclusion: Proprioceptive Neuromuscular Facilitation (PNF) significantly improves muscle strength in post-stroke patients, particularly in the upper limbs.

Abstract

Background: Major surgery is frequently associated with high levels of preoperative anxiety, which can negatively affect physiological stability and postoperative recovery. Despite evidence supporting the effectiveness of nature-based virtual reality (VR) therapy in reducing anxiety in high-income settings, its applicability in low- and middle-income countries (LMICs), particularly district hospitals, remains unclear. This study aimed to evaluate the effectiveness of nature-based VR therapy in reducing preoperative anxiety among first-time major surgery patients. Methods: This study employed a quasi-experimental pre-test–post-test control group design, reported in accordance with the TREND guideline. A total of 104 adult patients scheduled for first-time elective major surgery were recruited using consecutive sampling and equally allocated to an intervention group (n=52) and a control group (n=52). The independent variable was nature-based VR therapy, and the dependent variable was preoperative anxiety. Anxiety was measured using the State Anxiety subscale of the State–Trait Anxiety Inventory (STAI), a validated instrument with good reliability (Cronbach’s α = 0.83). The intervention group received a single 5-minute nature-based VR session 20–30 minutes before surgery, while the control group received standard preoperative care. Data were analyzed using paired and independent t-tests, and effect size was calculated using Cohen’s d. Results: Participants were predominantly aged 46–60 years (39.4%), equally male and female, mostly classified as ASA II (69.2%), and commonly scheduled for abdominal surgery (40.4%). The intervention group showed a significant anxiety reduction (mean difference = −16.10; p < 0.001; Cohen’s d = 1.98), whereas the control group showed no significant change (−2.38; p = 0.062). Post-intervention anxiety scores were significantly lower in the VR group than in the control group (t = 9.074; p < 0.001; Cohen’s d = 1.78). Conclusion: Nature-based VR therapy is an effective, nurse-led, non-pharmacological intervention for reducing preoperative anxiety in first-time major surgery patients. Integration of VR into routine preoperative nursing care may enhance patient-centered care and support anxiety management in resource-limited hospital settings.
