The modified goniometric platform (MGP) is a novel instrument used to measure trunk rotation while sitting. A lack of reliable and valid evidence has been reported to measure trunk rotation using MGP. Therefore, this study was aimed to investigate the intra- and inter-rater reliabilities and validity of the MGP for measuring trunk rotation while sitting. Methods: Seventeen participants performed right trunk rotation followed by left trunk rotation (three repetitions for each trial) and two random measurements at 40-minute intervals. Inter-rater and intra-rater reliabilities were calculated using intraclass correlation coefficients (ICCs). Validity was assessed using the Pearson correlation coefficient (r). Results: The test and re-test inter-rater reliabilities for right trunk rotation were 0.990 and 0.986, respectively, and those for left trunk rotation were 0.989 and 0.978, respectively. The intra-rater reliabilities for right trunk rotation were 0.949 and 0.954, respectively, and those for left trunk rotation were 0.944 and 0.946, respectively. The right and left trunk rotation validities were 0.986 and 0.981, respectively. Conclusion: MGP is reliable and valid for measuring right and left trunk rotations while sitting.

Flossband, as a novel and effective tissue flossing technique, is becoming increasingly popular in the field of athletic training, sports injury prevention, and rehabilitation. The purpose of this literature review is to summarize updated evidence about the effects of flossband application on joint range of motion (ROM), pain, muscle tightness, strength, and physical functional performance as well as identify research gaps for future study. Google Scholar, PubMed, EBSCO, and Web of Science were used to search related articles. The keywords of floss bands, flossbands, floss band, tissue flossing, flossing band, voodoo floss band, voodoo floss bands, track floss, rock floss, life floss band, and Rogue voodoo floss were used to extract target articles. English journal articles, full-text available, and content related to outcome measures were included. Conference abstracts, books, case studies, guideline reviews were omitted. 23 full-text journal articles were included for further qualitative analysis after removing duplicates and deleting articles that violate the screening criterion. Flossband application on limbs, soft tissue, or joints with about 50% flossing tension or 150 mmHg wrapping pressure could have small to medium effects on the parameters of ROM, muscle stiffness, muscle strength, and physical function performance, and large effects on pain management. Most previous studies were mainly focused on the acute effect of flossband application on peripheral joints or soft tissues in healthy and active participants or well-trained athletes. Therefore, for future studies, more evidence is needed on the benefits of long-term flossband trunk application and concerning patients with various diseases.

Practically every one involved in sports practice would experience Delayed-Onset-Muscle-Soreness (DOMS). Several modalities have been utilized to reduce DOMS such as anti-oxygen vitamin and drugs intake, ice bath, spa and pre and post exercise stretching. However, not all recovery modalities have been scientifically proven to aid DOMS recovery. This study was carried out to examine the effectiveness of several physical modalities for treating DOMS after training. The purpose of this study was to examine the effectiveness of Rossiter System® stretching and light aerobic activities for recovering from DOMS. Thirty six healthy male subjects volunteered to participate in this study and were randomly divided into three groups; a control group (KK), the Rossiter group (KR) and the aerobic group (KA). DOMS was induced through the completion of five sets of eccentric bicep curls with dumbbells weighing 13kg, 10kg, 7kg, 5kg and 3kg. Subjects were required to maintain five seconds throughout the descending phase of the bicep curls untill failure for each set. The KK group rested right after the bicep curls. The KR group performed Rossiter System® stretching while the KA group performed 50 repetitions of bicep curls without dumbbells at their own pace immediately after the exercise. Data such as plasma creatine kinase (CK), biceps’ circumference and perceptive soreness scales were obtained before, immediately right after, 24, 48, 72, 120 and 168 hours after DOMS was induced. Subjects were instructed to fully restrict supplement and drug intake and not be involved in aggressive physical activity and self massage during the period of the study. Three subjects were dropped from this study due to non-adherence to the criteria of the study. Results of the data analysis indicated that they were no significant different between KR and KA against KK for all testing sessions. Data also indicated that they were no significance difference between KR and KA against all three dependant var
