Background: Lateral epicondylalgia (LE) causes ineffective handgrip due to microtrauma on the elbow's common extensor origin. Objectives: This study will determine the differences in the Extensor Digitorum Communis' (EDC) fascia slide, percentage maximum voluntary contraction (%MVC), static maximum handgrip strength (SMHGT), muscle activation onset time (MAOT) in LE and non-LE elbows, with and without Biomechanical Tape (BMT). The study will determine differences in Visual Analogue Scales (VAS) and Patient Rated Tennis Elbow Evaluation (PRTEE) scores of patients with and without BMT. Methods: Nineteen participants' elbows with unilateral LE with and without BMT will be evaluated using musculoskeletal ultrasound (MSK) and electromyography (EMG) on Days 1, 3, and 5. A Physiotherapist-Sonographer, a Physiotherapist-EMG user, and a Research Assistant using Jamar hydraulic dynamometer will evaluate the participants. The participants will perform Mill's test during MSK and SMHGT using the dynamometer during EMG. A Chi-squared test will evaluate the relationship between BMT and fascia slide. Two-way repeated-measures ANOVA will compare the fascia slide, %MVC, SMHGT, and MAOT between elbows with and without BMT. It will be blocked according to elbow status (i.e., LE, no LE). Dunnett post hoc test will determine the groups whose results differed significantly. Differences in PRTEE scores at Days 1 and 5 will be determined. A p-value <0.05 indicates a significant difference in scores. Expected Results We expect decreased fascial slide measurements on EDC, VAS, PRTEE scores, and increased %MVC, MAOT, and SMHGT on taped elbows. Results will determine the underpinning mechanism behind the short-term effects of BMT.

BACKGROUND: Inversion ankle sprains are among the most common traumatic injuries for both men and women caused by jumping and landing activities. The ankle is protected by the static and dynamic stabilizers to reduce the incidences of injuries. Furthermore, using a non-elastic closedbasket weave taping technique is one of the common interventions to prevent it. Knowledge about the muscle activity reaction of the dynamic stabilizers upon application of tape is limited with varying results. OBJECTIVES: To determine the effect of non-elastic closed-basket weave ankle taping on the muscle activity of tibialis anterior, peroneus longus, medial, and lateral gastrocnemius on healthy individuals during jump landing on a hard, flat surface. METHODS: This study is a quasi-experimental study using a pre- and post-test design. Peak amplitude muscle activity was assessed and analyzed using surface electromyography (sEMG) after landing from a jump. The pre-test was done by jump landing without tape, after which post-test data was immediately collected after applying the non-elastic closed-basket weave taping. Jump landing was done for three trials for both pre- and post-tests. A paired t-test was used to determine significant differences in pre-post taping. RESULTS: Fifteen healthy participants were included in the study (9 females, 6 males) with a mean age of 21 + 1.03 years old and BMI of 22.74 + 1.63 kg/m2. No significant difference was observed on peak amplitude muscle activity of the tibialis anterior (p= 0.06), medial gastrocnemius (p= 0.32), and lateral gastrocnemius (p= 0.66) after application of tape. However, a significant difference was observed in the peroneus longus after the application of tape (p= 0.05) during jump landing CONCLUSION Non-elastic closed-basket weave taping decreased the peak amplitude muscle activity of the peroneus longus during jump landing. This research suggests that tape may influence the peroneus longus, and it may or may not be detrimental in reducing the risk of ankle sprains.

To survey the basic measurements of urodynamic as cystometry, uroflowmetry, electromyography, urethral profilometry. Currently, it may be to combine measurements each other or urodynamic with image diagnostic technique in order to have comprehensive consideration, more accurate on lower urinary tract function: To combine with cystometry, uroflowmetry and electromyography, detrusor pressure measurement, to combine with cystometry and observe reflection of light of cystoids under fluorescent screen, video-urodynamics

OBJECTIVE: This study was carried out to investigate the characteristics of satellite potentials in clinical electromyography. METHOD: A conventional concentric needle electromyography was applied to the biceps brachii and tibialis anterior muscles in 32 normal controls and 14 patients with neuropathies. The satellite potentials were defined as small extrapotentials, preceding or following the main motor unit action potentials(MUAPs) and separated from MUAPs by an isoelectrical interval of at least 1 msec. RESULTS: In normal controls, the frequency of satellite petentials was 1.27% in the biceps brachii and 1.48% in the tibialis anterior and it was increased in neuropathy by 8.53% (6.7 times of control value) in the biceps brachii and 6.70% (4.5 times of control value) in the tibialis anterior. The satellite potential parameters were not significantly different between the control and neuropathy groups. The amplitude of MUAPs with satellite potentials was significantly higher than that of MUAPs without satellite potentials. CONCLUSION: The satellite potentials could be used as a valuable and easily obtainable, supplemental electromyographic parameters for the detection of neuromuscular disorders.

PURPOSE: This study examined the influence of longitudinal arch on the strength and muscle activity of the abductor hallucis in the standing position in subjects with and without navicular drop signs. METHODS: A sample of 34 subjects with and without navicular drop signs between 22 and 28 years of age were enrolled in this study. The strength and muscle activity of the abductor hallucis was measured using a tensiometer. The Smart KEMA System and electromyography device was used on the subjects with and without navicular drop signs. Two groups were classified using the navicular drop test to identify the longitudinal arch of the foot. The strength of the abductor hallucis was evaluated in standing, both with and without an external arch support condition. The two-way mixed ANOVA was used. The level of statistical significance was set to α=0.05. RESULTS: The strength and muscle activity of the abductor hallucis in standing was significantly higher with external arch support than that without the external arch support in the group with navicular drop signs. There was no significant difference in the abductor hallucis strength and muscle activity with and without external arch support in the subjects without navicular drop signs. CONCLUSIONS: The strength and muscle activity of the abductor hallucis in standing can be influenced by the external arch support in the group with navicular drop signs. The strength measurement of the abductor hallucis in standing should be separately performed in conditions with and without longitudinal arch of foot.
