Electrical twitch obtaining intramuscular stimulation (ETOIMS) for myofascial pain syndrome in a football player
British Journal of Sports Medicine, 2004Co-Authors: J. ChuAbstract:BACKGROUND: Flare up of acute lower back pain associated with myofascial pain syndrome (MPS) may require various forms of treatment including activity restriction and bracing. Electrical twitch obtaining intramuscular stimulation (ETOIMS) is a promising new treatment. It involves the use of a strong monopolar electromyographic needle electrode for electrical stimulation of deep motor end plate zones in multiple Muscles in order to elicit twitches.\n\nCASE REPORT: An elite American football player with MPS symptoms failed to respond to standard treatments. He then received ETOIMS which completely alleviated the pain. After establishing pain control, the athlete continued with a further series of treatments to control symptoms of Muscle Tightness.\n\nCONCLUSIONS: ETOIMS has a promising role in pain alleviation, increasing and maintaining range of motion, and in providing satisfactory athletic performance during long term follow up.

comparison of the duration of maintained calf Muscle flexibility after static stretching eccentric training on stable surface and eccentric training on unstable surfaces in young adults with calf Muscle Tightness
Physical Therapy Korea, 2014Co-Authors: Heejin Jang, Hyunjeong JangAbstract:The objective of this study was to determine the duration of maintained calf Muscle flexibility gained in young adults with calf Muscle Tightness, as measured by increases in ankle active and passive dorsiflexion range of motion (DFROM) after three stretching interventions. Twenty subjects (5 men and 15 women) with calf Muscle Tightness received the following three stretching interventions in one leg (assigned at random): static stretching (SS), eccentric training on stable surface (ETS), and eccentric training on unstable surfaces (ETU). The subjects received all three interventions to the same leg, applied in a random order. Each intervention had a break of at least 24 h in-between, in order to minimize any carryover effect. Each intervention used two types of stretching: with the calf Muscle stretched and both knees straight, and with the knee slightly bent in order to maximize the activation of the soleus Muscle. All three interventions were performed for 200 seconds. We measured the duration of maintained calf Muscle flexibility through active and passive ankle DFROM before intervention, immediately after intervention (time 0), and then 3, 6, 9, 15, and 30 min after intervention. We found a difference in the duration of maintained calf Muscle flexibility between the three interventions. In the ETS and ETU interventions, a significant improvement in calf Muscle flexibility, both ankle active and passive dorsiflexion ranges of motion (ADFROM and PDFROM), was maintained for 30 min. In the SS intervention, however, ADFROM before 9 min and PDFROM before 6 min were statistically different from the baseline. Our results suggest that ETS and ETU may be more effective than SS for maintaining calf Muscle flexibility in young adults.

Muscle Flexibility as a Risk Factor for Developing Muscle Injuries in Male Professional Soccer Players A Prospective Study
American Journal of Sports Medicine, 2017Co-Authors: Erik Witvrouw, Lieven Danneels, Peter Asselman, Thomas D'have, Dirk CambierAbstract:Background: Muscular Tightness is frequently postulated as an intrinsic risk factor for the development of a Muscle injury. However, very little prospective data exist to prove this.Hypothesis: Increased Muscle Tightness identifies a soccer player at risk for a subsequent musculoskeletal lesion.Study Design: Prospective cohort study.Methods: We examined 146 male professional soccer players before the 1999—2000 Belgian soccer competition. None of the players had a history of Muscle injury in the lower extremities in the previous 2 years. The flexibility of the hamstring, quadriceps, adductor, and calf Muscles of these players was measured goniometrically before the start of the season. All of the examined players were monitored throughout the season to register subsequent injuries.Results: Players with a hamstring (N = 31) or quadriceps (N = 13) Muscle injury were found to have significantly lower flexibility in these Muscles before their injury compared with the uninjured group. No significant differences...

intrinsic risk factors for the development of patellar tendinitis in an athletic population a two year prospective study
American Journal of Sports Medicine, 2001Co-Authors: Erik Witvrouw, Roeland Lysens, Johan Bellemans, Lieven Danneels, Dirk CambierAbstract:Retrospective studies have suggested various factors that might cause a disposition to develop patellar tendinitis, but no prospective data exist to determine any relationships. The purpose of this study was to determine the intrinsic risk factors for the development of patellar tendinitis in an athletic population. Before the study, 138 male and female students of physical education were evaluated for anthropometric variables, leg alignment characteristics, and Muscle Tightness and strength parameters. During the 2-year study, 19 of the 138 students developed patellar tendinitis. In all cases the diagnosis was confirmed by the presence of a hypoechogenic nodular lesion in the proximal region of the patellar tendon. Univariate and stepwise discriminant function analyses were performed comparing the various measurements. These analyses revealed that the only significant determining factor was muscular flexibility, with the patellar tendinitis patients being less flexible in the quadriceps and hamstring mus...

comparison of effects for application of proprioceptive neuromuscular facilitation technique and static stretching on the calf Muscle
Physical Therapy Korea, 1995Co-Authors: Yongtack Park, Sungyon Hwang, Hyukcheol KwonAbstract:The purpose of this study was to compare the effects of one proprioceptive neuromuscular facilitation technique and static stretching on calf Muscle Tightness. The subjects consist of 9 hemiplegics, and 9 quadriplegics. The eighteen subjects were randomly divided into 3 groups: prorioceptive neuromuscular facilitation(6 persons), static stretching(6 persons) and control(6 persons). Contract relax antagonist contract and static stretching techniques were applied continuously for twenty minutes each. Of the many proprioceptive neuromuscular facilitation techniques, only the contract relax antagonist contract technique was applied. The static stretching technique was applied with the subject placed in standing on a seventy degree inclined tilt table for twenty minutes. A wedge was placed under the feet to obtain maximum dorsiflexion. Wedge thickness varied with each subject. Results revealed: (1) a significant difference between the experimental and the control groups(p, static stretching (meanstandard deviation).

lower extremity injuries in college athletes relation between ligamentous laxity and lower extremity Muscle Tightness
Archives of Physical Medicine and Rehabilitation, 1996Co-Authors: Lisa S Krivickas, Joseph H FeinbergAbstract:Abstract Objective: Two components of flexibility, Muscle Tightness, and ligamentous laxity in college athletes were studied to determine whether these factors were associated with the incidence of lower extremity injuries. Design: Prospective cohort study. Setting: College athletic department. Participants: 201 college athletes. Outcome Measures: College men and women athletes were tested for ligamentous laxity with the Beighton scale and for Muscle Tightness with a new scale based on the Tightness of the iliopsoas, iliotibial band, hamstring, rectus femoris, and gastrocsoleus Muscles. Lower extremity injuries incurred during practice and play were recorded during the following year. Results: Of the 201 athletes tested, 71 sustained 115 injuries. For each additional point on the 9-point ligamentous laxity scale (9 = hyperlax), the risk of injury decreased 16%. For each additional point on the 10-point Muscle-Tightness scale (10 = all Muscles tight), the risk of injury increased 23%. The two scores were moderately inversely correlated (Spearman's rho=−0.3; p p p p = .008) and greater Muscle Tightness ( p = .04). Conclusions: This study introduces a new scale for lower extremity Muscle Tightness. Tight ligaments and Muscles are related to injury in men, but not women, college athletes. A preseason flexibility program may decrease injuries in college men athletes.
