Purpose: This study aimed to analyze the effects and intervention methods of aromatherapy studies in nursing. Methods: A systematic literature review was conducted. Nursing literature databases were searched to identify intervention studies published in Korea between 2000 and 2011. Finally, 53 articles were included in the review. Results: The most preferred application method of aromatherapy was massage. The major dependent variables were anxiety, depression, pain, and sleep disturbance. 76.5% of the studies reported positive effects on anxiety. 93.8% of the studies reported positive effects on depression. 86.7% of the studies reported positive effects on pain. 92.3% of the studies reported positive effects on sleep disturbance. Psychometric measurements were mainly used in the studies. Only 33.9% of the studies adopted physical or physiological measurements. The most prevalent physical or physiological instrument was vital signs. Conclusion: Aromatherapy had positive effects on anxiety, depression, pain, and sleep disturbance measuring when using psychometric instruments. However, there was no sufficient evidence measuring when using physical or physiological instruments. These need to be studied using well-designed, randomized, controlled trials, and should encourage the use of both psychometric and physiological measures for aromatherapy intervention in nursing studies.

The purpose of this study was to investigate the relationship between the quantitative analysis of biomechanical movement and the qualitative analysis of video software in order to evaluate for the walking movement. The fourteen collegiate students who agreed with the purpose and method of this study participated as subjects. The slow walking and fast walking of the subjects in the place of experiment were photographed, and calculated several mechanical factors. This empirical evidence from the experiment indicated the significant difference(p<.001) between each distant factors of the walking movement for both analyses methods, but there was no statistically significant difference between the spacial factors observed in the experiment. For more detail, no significant difference between the walking ratios that expressed the coordination between stride length and stride frequency was found. The findings also indicated the high coefficient of correlation(over r=.9) which supports higher explanation force for the biomechanical method and the Dartfish video software method. Therefore, if the data was gathered by using the proper experimental method, the video software method could be used just like the quantitative data of biomechanical method.

Purpose: The purpose of this study was to examine effects of a muscle strength reinforcement exercise program (MSREP) for older adult patients with hemodialysis (OAPHD) which was designed to improve health status and quality of life of these older adult patients. Methods: Participants were 40 patients with OAPHD: 20 in the experimental group and 20 in the control group. MSREP was conducted with the experimental group for 12 weeks at H geriatric hospital. An assessment was done to determine effects on physical performance, inflammation index, fatigue, muscle strength and quality of life. Short physical performance battery, C-Reactive Protein (CRP), visual analog scale for fatigue, object lifting' proposed by the Life Options Rehabilitation Advisory Council, sit-to-stand test, and quality of life index were used to gather data. Results: Between the 2 groups there was no significant difference in scores for physical performance, fatigue or quality of life. However, the 2 groups showed significant difference in CRP values and muscle power scores on post-test. Conclusion: Findings provide evidence for the potential utility of education for older adult patients with hemodialysis. Also, this program could allow these patients to increase muscle strength, and contribute to achieving better health conditions in OAPHD care.

Background: Chronic neck pain (CNP) is associated with weakness in the deep neck flexor muscles, a shortening of the neck extensors, and a reduction in endurance. In addition, muscle imbalance can lead to neck pain and musculoskeletal dysfunction. This study compared neck extensor muscle fatigue, muscle strength, and muscle endurance time between patients with CNP and healthy adults during isometric neck extension. Methods: Thirty participants (15 patients with CNP and 15 healthy adults) were recruited in this research. The outcome measures included splenius capitis (SC) muscle fatigue, isometric neck extensor strength, and muscle endurance. The independent T-test was used to compare the continuous dependent variables between the CNP group and the healthy group. Results: The independent T-test indicated that muscle fatigue in the left SC differed significantly between the CNP group and the healthy group. A significant difference was also noted in the isometric neck extensor and neck extensor strength between the groups. Conclusion: Our results provided promising clinical evidence that patients with CLP have reduced neck extensor strength and endurance and increased SC muscle fatigue, which results in neck pain.

Background: The serratus anterior and upper trapezius muscles act synergistically to allow for an appropriate scapulothoracic rhythm. However, a decrease in serratus anterior activation causes the upper trapezius to become overactivated, resulting in dysfunction. This study compared serratus anterior and upper trapezius muscle activity according to sling angle and compared serratus anterior strength between healthy adults and patients with shoulder instability. Methods: Twenty participants (10 healthy adults and 10 patients with shoulder instability) were included in this study. The participants had their arms extended at sling angles of 30°, 60°, and 90° in reach forward with shoulder flexion using goniometer. Serratus anterior strength was measured three times while the participants were supine. The outcome measures were surface electromyography amplitude of the upper trapezius and serratus anterior and serratus anterior strength. Results: The Wilcoxon signed-rank test indicated that the upper trapezius was significantly different between healthy group and shoulder instability group at a sling angle of 60°, and both the upper trapezius and serratus anterior exhibited significant differences at 90°. Moreover, a significant difference was noted in the muscle strength of the serratus anterior. Conclusion: Our results provide novel and promising clinical evidence that patients with shoulder instability have decreased serratus anterior activation and upper trapezius overactivation, resulting in muscle imbalance. In addition, there was a significant difference between the healthy group and shoulder instability group in the serratus anterior muscle strength

Background: In clinical practice, active knee extension (AKE) test has been widely used to measure hamstring flexibility. During the AKE test, the knee extension is repeated six times. The first five repetitions are considered as warm-up, and the sixth is used as baseline. In order to accurately measure the subject's inherent flexibility, warm-up trials have been proposed as mentioned above; but currently, the evidence is insufficient. Design: Cross-sectional study. Methods: Forty-three healthy adults participated in this study. The AKE was performed slowly after flexing the hip and knee joints by 90° in a supine position. The knee was extended as far as could be done without causing discomfort or pain. When reaching the end range, knee flexion was performed without stopping. As per standard protocol, the subjects performed the knee extension six times. Results: There was no significant difference between the AKE value in the first trial with those in the other five trials. During the repetitions, the average value in the group with higher flexibility tended to decrease and the Intraclass correlation coefficient gradually decreased. Conclusion: Successive repetitions of the AKE test can misrepresent an individual's inherent hamstring flexibility. In order to avoid a decrease in hamstring flexibility, it is strongly recommended that individuals with high initial hamstring flexibility avoid unnecessary repetitions of the AKE test.

Background: The myofascial release technique is known to be an effective technique for increasing posterior fascia flexibility in short hamstring syndrome (SHS) subjects. But therapeutic mechanism of myofascial relaxation remains unclear. Recently, the theory of autonomic nervous system domination has been raised, however, a proper study to test the theory has not been conducted. Objectives: To investigate whether the application of the myofascial release technique can induce changes in the autonomic nervous system and affect the secretion of stress hormones and myofascial relaxation. Design: Quasi-experimental study. Methods: Twenty-four subjects with SHS were randomly divided into two groups. In the experimental group, the suboccipital muscle inhibition (SMI) technique was applied to the subjects for 4 min in supine position, and in the control group, the subjects were lying in the supine position only. A forward flexion distance (FFD) was conducted, blood pressure, heart rate, and cortisol levels were measured before and after the intervention and 30 min after intervention to determine myofascial relaxation and stress hormone levels. The evaluation was conducted separately in blind by an evaluator. Results: A FFD decreased in the experimental group, no change in cortisol was observed. On the contrary, a decrease in cortisol appeared in the control group after 30 minutes. Conclusion: The myofascial release technique is an effective treatment to increase the range of motion through posterior superior myofascial chain, but there is no evidence that myofascial release technique can control the autonomic nervous system.

Background: Repetitive damage to the ankle joint causes chronic ankle instability, and studies comparing the effects of exercise in open and closed chains as a treatment method are very rare. Objectives: To investigate the effects of open and closed kinetic exercises on muscle activity and dynamic balance of ankle joint in adults with chronic ankle instability. Design: Single-blind randomized controlled trial. Methods: The selected 30 subjects are randomly divided into open kinetic chain exercise experimental group (EGI, n=10), closed kinetic chain exercise experimental group (EGII, n=10), and stretching control group (CG, n=10). Open and closed kinetic exercises lasted 30 minutes three times a week for six weeks and stretching exercises performed four actions for 20 seconds and five sets. The measurement tools using surface electromyography to measure muscle activity in the ankle joint. The dynamic balance of the ankle was evaluated using the Y-Balance test. Results: Following the intervention, closed and open kinetic chain exercise group showed significant difference in tibialis anterior and gastrocnemius muscle activity and dynamic balance (P<.05). However, no significant difference in tibialis anterior and gastrocnemius muscle activity and dynamic balance between closed and open kinetic chain exercise group (P<.05). Conclusion: This study provides evidence that closed and open kinetic chain exercise can be presented as an effective exercise for the muscle activity of ankle muscle and dynamic balance of the subject with chronic ankle instability.

A normal range of motion is essential for performing activities of daily living. The capsular pattern is the proportional motion restriction in range of motion during passive exercises due to tightness of the joint capsule. Although the capsular pattern is widely referred to in clinical practice, there is no scientific evidence to support the concept. In this review, the appropriateness of the capsular pattern for evaluation of joint pathology was assessed. In the Textbook of Orthopaedic Medicine written by Cyriax, the capsular pattern did not specify how much reduction in angular motion is considered motion restriction. As the definition proposed initially was unclear, different methods have been used in previous studies investigating capsular pattern. In addition, the capsular pattern described all the major joints of the human body, but only the hip joint, knee joint, and shoulder joint were studied in experimental studies. Sensitivity and specificity were reported in one study and were meaningful in specific pathologies (loss of extension to loss of flexion). There was no consensus on the reliability and validity. In summary, the capsular pattern suggested by Cyriax or Kaltenborn is not supported or applies only to certain conditions. Various components around a joint complement each other and provide stability to the joint. It is recommended that the therapist perform multiple assessments rather than rely on a single assessment when evaluating joints.

Purpose: Due to the COVID-19 and inflation, participation sports companies, including fitness centers, are facing challenges. Since a fitness center must simultaneously manage facilities and operate services, both factors must be considered when developing a marketing strategy. Therefore, this study examines the effects of expanded marketing mix factors (price, physical evidence, place, people, product, and promotion) including facilities and services on the consumption behavior (satisfaction, recommendation intention, repurchase intention) of fitness center customers. Research design, data, and methodology: The data were collected from sample of 323 fitness club members in Seoul and analyzed with SPSS Win Ver.28.0 program. Result: The specific results of the study were as follows; First, extended marketing mix factors had significant positive (+) effect on satisfaction. Second, extended marketing mix factors had significant positive (+) effect on recommendation intention. Third, extended marketing mix factors had significant positive (+) effect on repurchase intention. Fourth, satisfaction had significant positive (+) effect on recommendation intention and repurchase intention. Conclusions: To encourage consumption behavior, it is necessary to convert existing customers into loyal ones by increasing satisfaction and establishing a virtuous cycle structure that recommends them to others while also improving repurchase intention.
