Abstract Background The aim of the study is comparison of the effects of soft tissue manipulation and rest on the knee extensor muscle fatigue after maximal isokinetic contractions. Methods Fifteen healthy females aged 20-30 years selected for research. This study implemented a semi-experimental test-retest measurement method. Each of the volunteers was evaluated three sessions. The first session was to familiarize the volunteers with the test and isokinetics. For the main test, each of the volunteers was evaluated twice with a one-week interval between evaluations. In each session, after warm-up, perceived fatigue using a visual analog scale (VAS), average of peak torque (APT), and average power (AP) for maximal concentric isokinetic output of the quadriceps was measured at a velocity of 60 degrees per second. Then¸ in order to apply the fatigue protocol, the subjects were asked to perform successive maximal quadriceps contractions until three consecutive quadriceps torque outputs reached below 50 percent maximal torque output. Afterwards, for remeasurement, the average of peak torque and average power were calculated. The extent of perceived fatigue was evaluated as before. Subjects then either rested or received soft tissue manipulation on the knee extensors for a 15-minute duration. After intervention (soft tissue manipulation or rest) parameters were evaluated for third time. Results The stability of average peak torque¸ average power, and visual analog scale before performing fatigue protocol was 85%, 83%, and 31.9%, respectively. The stability after fatigue was 43%, 50%, and 93%, respectively. After maximal fatigue and a decrease in torque output to below 50 percent maximal torque, 15 minutes of soft tissue manipulation could change the APT after fatigue from a mean of 58.3 (nm) to 91.5 (nm), the AP from 39.4 to 63.6 (nm/s), and the VAS from 90.0 to 12 (mm). But 15 minutes of rest could change the APT from 52.5 to 68.1 (nm), the AP from 37.6 to 48 (nm/s) and the VAS from 90.0 to 27.3 (mm). Conclusion The study showed that soft tissue manipulation was more effective than rest as a strategy to return muscles to a normal state and caused more relief in perceived fatigue.

Soft Tissue Mobilization

AbstractThis study aimed to examine the effects of a rehabilitation exercise combined with instrument-assisted soft tissue mobilization on the isokinetic power, muscle fatigue, and fitness of soccer players. An interventional study design was used to assess 40 subjects aged 15–17 years. Twenty participants each in instrument-assisted soft tissue mobilization and control groups completed several tests to determine player development. The results showed significant differences between the two groups with respect to the isokinetic power of the ankle (i. e., dorsiflexion, peak torque body weight at the right- and left-foot angular velocities of 30°/s and 120°/s; plantar flexion, peak torque body weight at the right- and left-foot angular velocities of 30°/s and 120°/s) and knee (extension, right peak-torque body weight at 60°/s and 180°/s and left peak-torque body weight at 60°/s; flexion, right and left peak-torque body weight at 60°/s and 180°/s), muscle fatigue, and physical fitness (P<0.05). Instrument-assisted soft tissue mobilization in soccer players suggests that the characteristics of athletic performance may be improved by decrease in fatigue and increase in fitness and muscle power. Therefore, we suggest instrument-assisted soft tissue mobilization for soccer players to increase their performance.

Objective:This study sought to determine the effects of trunk-muscle fatigue and blood lactic acid elevation on static and dynamic balance.Intervention:Fatigue was induced by an isokinetic protocol, and static and dynamic balance were assessed during bilateral stance using a Kinesthetic Ability Trainer. Subjects participated in a fatigue protocol in which continuous concentric movements at 60°/s were performed until the torque output for both trunk flexion and extension dropped below 25% of the calculated peak torque for 3 consecutive movements.Measures:Before and immediately after the fatigue protocol, blood lactic acid measurements and static- and dynamic-balance measurements were recorded.Results:An increase in lactic acid levels was detected in all subjects. According to a dependent-samples t test, significant differences in balance and lactic acid values were found after the fatigue protocol. There was no correlation between lactic acid accumulation (change between prefatigue and postfatigue levels) and balance-score differences.Conclusion:Trunk-muscle fatigue has an adverse effect on static and dynamic balance.

Abstract OBJECTIVE: Our goals are to describe a method of treating painful peripheral nerve neuromas by means of vascularized tissue coverage, report the results in seven patients, and discuss the indications for this treatment modality. An analysis of pain, functionality of the affected body part, professional activities of the patients, and medications before and after surgery is presented. METHODS: Seven male patients (mean age, 45.1 yr) with posttraumatic nerve injuries, who had developed painful stump neuromas or neuromas-in-continuity, and who had unsuccessfully undergone several treatment procedures, were selected for the surgery described here. The operation included resection of the stump neuroma (four patients) or neurolysis of the neuroma-in-continuity (three patients) and coverage of the nerve with a vascularized fascial, fasciocutaneous, or perforator flap (three pedicled regional flaps and four free flaps). A modified quadruple visual analog scale was used to quantify pain before and after surgical treatment. The mean follow-up was 16.6 months. RESULTS: The mean values of the quadruple visual analog scale (pain now/typically/at its best/at its worst) before surgery were 6.5/6.5/4.7/7.9. These values changed to 0.3/0.4/0/0.9 at a mean follow-up of 16.6 months after surgery. Five patients returned to their original profession, one receives a pension, and one began a less demanding job after undergoing surgery. Six of the seven patients received opioids before surgery (one had a spinal cord stimulator). After surgery, all patients stopped taking regular pain killers and the spinal cord stimulator was deactivated in one; two patients still take nonsteroidal anti-inflammatory drugs occasionally, but not on a regular basis. CONCLUSION: Vascularized soft tissue coverage of painful peripheral nerve neuromas seems to be an effective and attractive, but also complex, method of treatment. This option may be considered and reserved for patients who have already undergone several pain treatment modalities without success.

ABSTRACT Introduction: Muscular fatigue during voluntary muscle contractions is a complex and multifactorial phenomenon associated with central changes and adaptations of the neuromuscular system. Objective: The aim of this study was to analyze the changes in both peak torque and hematological parameters in active and inactive healthy subjects following a muscular fatigue protocol. Methods: Twenty-one healthy adult males performed a muscle fatigue protocol (10 sets, 10 repetitions of knee extension at 75% of the maximal isometric torque (MIT), 120º s-1 and 40 seconds of rest). Hematocrit (Ht), red blood cells (RBC) and leukocytes (L) analysis were evaluated before (B) and after (A) a fatigue test. Results: The inactive group presented impairment only in concentric muscular action of -41±4% in relation to the active (-23±3%) group. No differences were found in hematological parameters in inactive group (Ht, B: 45.00±0.01 vs. A: 47.00±0.01; RBC, B: 442±40 vs. A: 487±41; L, B: 7,565±2,878 vs. A: 8,015±4,224) and the active group (Ht, B: 45.00±0.63 vs. A: 47.00±0.01; RBC, B: 477±30 vs. A: 559±37; L, B: 6,418±3,557 vs. A: 6,632±4,460). Conclusion: Differences were found only in concentric actions between groups. Additionally, there were no relationships found in hematological parameters between groups.

ZusammenfassungDie Wirksamkeit, Sicherheit und Verträglichkeit einer Einzelgabe von zwei Tabletten der fixen Dreierkombination mit 250 mg Azetylsalizylsäure (ASS) plus 200 mg Paracetamol plus 50 mg Koffein (Thomapyrin®) gegenüber zwei Tabletten mit 500 mg ASS, oder zwei Tabletten mit 500 mg Paracetamol, oder zwei Tabletten mit 50 mg Koffein beziehungsweise Plazebo wurde in einer klinischen Studie an 1 743 Patienten geprüft, die ihre episodischen Kopfschmerzen vom Spannungstyp oder ihre Migräne mit und ohne Aura üblicherweise erfolgreich mit verschreibungsfreien Analgetika behandeln. Die Dreierkombination war im a priori definierten primären Endpunkt “Zeit bis zu 50% Schmerzreduktion” sowohl der Zweierkombination aus ASS plus Paracetamol (p = 0,0181), als auch den Monoanalgetika ASS (p = 0,0398) und Paracetamol (p = 0,0016), sowie auch der Monotherapie mit Koffein (p < 0,0001) und Plazebo (p < 0,0001) überlegen. Alle Behandlungen außer der Koffein-Monotherapie waren der Plazebobehandlung überlegen (p < 0,0001). Die überlegene Wirksamkeit der Dreierkombination gilt auch für alle sekundären Endpunkte wie beispielsweise der “Verringerung der Kopfschmerzen auf 10 mm VAS (visual analog scale = visuelle Analogskala zur Schmerzmessung), dem gewichteten % SPID (sum of pain intensity difference = aufsummierte Schmerzintensitätsdifferenz gegenüber dem Ausgangsschmerz in Prozent), dem Ausmaß der Beeinträchtigung der alltäglichen Aktivitäten und der globalen Beurteilung der Wirksamkeit durch die Patienten. Alle Behandlungen waren gut verträglich, die Inzidenz von unerwünschten Begleiterscheinungen war gering.

Preliminary Study

Perceived valence, tension, and movement of harmonic musical intervals (from the unison to the octave presented in a low- and high-register) and standard noises (brown, pink, white, blue, purple) were assessed in two studies that differed in the crossmodal procedure by which tension and movement were rated: proprioceptive device or visual analog scale. Valence was evaluated in both studies with the visual analog scale. In a preliminary study, the proprioceptive device was calibrated with a psychophysical procedure. Roughness of the stimuli was included as covariate. Tension was perceived higher in dissonant intervals and in intervals presented in the high register. The higher the high-pitch energy content in the standard noise, the higher the perceived tension. The visual analog scale resulted in higher tension ratings than the proprioceptive device. Perception of movement was higher in dissonant intervals, in intervals in the high register, and in standard noises than in musical intervals. High-pitch spectrum noises were associated with more sense of movement than low-pitch spectrum noises. Consonant intervals and low-register intervals were evaluated as more pleasant than dissonant and high-register intervals. High-pitch spectrum purple and blue noises were evaluated as more unpleasant than low-pitch spectrum noises.
