    Introduction: Our aim was to identify the mechanical properties of the latent myofascial trigger points (MTrPs), the taut band and the non-taut band (surrounding muscle) within the gastrocnemius muscle using the myotonometric evaluation method. Material and Methods: Thirty-one asymptomatic elite rugby players (23.0 +/- 4.16 y, 97.5 +/- 22.1 kg, 183.5 +/- 7.6 cm) with a latent MTrP in lateral gastrocnemius muscle included in this study. Muscle stiffness, decrement and muscle tone of latent MTrPs, taut band and the non-taut band were measured using a myotonometer (MyotonPRO, Myoton AS, Tallinn, Estonia). One-way ANOVA was conducted to determine the differences between the three measurement points. After pairwise comparisons, Cohen's d effect sizes were calculated to determine the magnitude of differences between the measurement points. Results: Although the stiffness of the latent MTrPs was lower than its taut band, one-way ANOVA revealed that there was no difference between the latent MTrPs vs the taut band and the non-taut band for frequency, stiffness and decrement parameters (p>0.05). However, there was a difference between the taut band non-taut band for muscle tone (P= 0.016), for stiffness (P=0.035) and for decrement (P=0.012) and effect sizes were as d=0.64, d=0.69 and d=0.62 for stiffness, muscle tone and decrement respectively. Conclusion: The MTrPs and the taut bands showed an increase in muscle stiffness and muscle tone compared to the surrounding muscle. The taut band can be easily identified from the surrounding muscle using the myotonometer. Therefore, myotonometric measurement is a potentially valuable method for the identification of the taut band in elite athletes.

    Acute Effects of Video Game-based Exercises in Patients Receiving Chemotherapy After Breast Cancer Surgery - A Pilot Study

    OBJECTIVE Virtual reality programs, which have developed rapidly with the advancement of technology, have led to the development of alternative treatment methods preferred in rehabilitation. This study aimed to investigate the acute effects of a video game-based exercise program applied after breast cancer surgery on the upper extremity functionality, pain severity, and the level of fatigue. METHODS Fifteen female patients aged between 30 and 60 years (50.13 +/- 8.79) who completed their 12th week after breast cancer surgery and were received adjuvant chemotherapy treatment were randomly included in this pre-test and post-test study. The patients were performed a 30-min video game-based exercise program. The muscle strength, range of motion (ROM), pain and fatigue level assessments were performed before and after the video game-based exercises. The level of exercise pleasure was determined with the modified visual analog scale. RESULTS Shoulder flexion, abduction, and external rotation ROM significantly increased after video game-based exercise program. No difference was detected for shoulder abduction muscle strength (p>0.05) and pain level significantly increased (p<0.05). The average exercise pleasure level is 4.5/5 and the average fatigue level was 11.13/20. CONCLUSION Video game-based exercises provided improvement in ROM of the shoulder joint without causing fatigue. Studies with different treatment durations are needed to minimize the increase in pain level.
