Pressure pain threshold (PPT) is defined as the minimum force applied which induces pain. This measure has proven to be commonly useful in evaluating tenderness symptom. Our aim was to study the intra-examiner reproducibility of PPT measurement, define cutoffs in normal groups, and compare these results with patients with fibromyalgia (FM). Fifty healthy females, 50 healthy males, and 20 patients with FM participated in the study. PPTs were assessed for 18 specific tender point sites by a dolorimeter. The intra-individual coefficient of variation determined by a test-retest PPT measurement procedure with 3-days interval reached, respectively, 17% and 13% in healthy females and males, versus 24% in patients with FM PPTs were significantly lower in healthy females than in healthy males (p < 0.01). Statistical analysis failed to show any differences between the dominant and nondominant side for both normal groups. PPTs were lower over all examined areas in patients with FM than those obtained in healthy females (p < 0.000). Lower cutoff levels were calculated from normal values for all specific tender point sites. On average, 14 tender point sites in patients with FM were under the established lower cutoffs. In conclusion, pressure pain sensitivity was influenced by the anatomical localization of tender point and gender differences. Lowest PPTs were localized in trapezius, occiput, anterior cervical, and second rib. The reduction of total tender point score in patients with FM averaged 60% comparatively with normal values. PPT reproducibility and discrimination between the two groups were optimal for the gluteal and knee sites.

Relatively little is known about isokinetic profiles of the forearm and wrist muscles. The aims of the study were therefore to prove the reproducibility of the measurements, to establish reference concentric and eccentric strength values and to determine the effectiveness of an isokinetic eccentric training model in treating chronic epicondylitis. The concentric and eccentric assessment of healthy male and female subjects allowed the analysis of different parameters: absolute and bodyweight normalized peak torque; bilateral asymmetries and conventional pronator / supinator and flexor / extensor ratios. We have studied the coefficients of variation in a test – retest session. At the same time, 32 patients diagnosed with chronic lateral epicondylitis benefited from an adapted isokinetic eccentric training model (20 to 30 sessions). The absolute reliability in repeated tests procedure of peak torque measurement appeared satisfactory with CV inferior to 12 %. The bilateral asymmetries did not exceed 24 %. PT ratio study reflected the superiority of the PRO and FLE muscles in comparison to the opposite groups. The eccentric rehabilitative model presented a very satisfactory effect on treating chronic epicondylitis with a significant reduction of pain (Visual Analogic Scale), improvement in the ultrasonographic examination (normalized echoic aspect in 53 % of cases) and normalization of maximal isokinetic strength. The isokinetic testing of the forearm pronosupinator muscles and wrist flexor-extensor muscles appeared reproducible. Referential values were proposed for different parameters allowing easier interpretation of pathological cases. The isokinetic eccentric rehabilitative model promoted the epicondylitis treatment.

Objectives: To explore the role of muscular strength and imbalance as predisposing factors in the development of anterior knee pain syndrome (AKPS). Methods: 96 male military recruits without history of knee pain volunteered for the study. Each volunteer underwent an isokinetic test prior to the start of a strenuous training program (approximately 8 to 12 hours/day for 6 weeks). The isokinetic test consisted of concentric contractions of the knee flexors and extensors at 60degrees/s and 240degrees/s. A detailed history and clinical examination of the patellofemoral joint was performed on each recruit. Independent sample t-tests were used to compare the isokinetic muscle parameters in recruits who developed AKPS during the training (pathological group) and in those who did not (control group). Binary logistic regression analysis was used to define the predictive outcome of anthropometrics and the isokinetic parameters for the development of AKPS. Results: 31 recruits developed AKPS. Absolute and bodyweight normalized peak extensor torque at 60degrees/s was significantly lower in the pathological group in comparison to the control group. Significant lower peak torque/BMI (Body Mass Index) were also indicated at both velocities. Recruits who developed AKPS had a shorter stature. No regression model could be set up to give any predictive value to the analyzed parameters. Conclusions: Recruits with shorter stature and lower quadriceps strength are more prone to develop AKPS during BMT. However, as the etiology of AKPS is multifactorial these parameters alone may not suffice to predict the occurrence of this pathology. On the other hand, the results of this study emphasize the importance of the reinforcement of quadriceps strength in the treatment and prevention of AKPS. [less ▲]

Investigating factors associated with muscle strains highlight the multifactorial origin of the injury and the difficulty of identifying isolated or combined factors that caused the injury. Among the numerous causes reported in the literature, only a few have been scientifically associated with injury occurrence, while others have been empirically suggested. Contradictions in articles dealing with muscle strength and imbalance are frequent, and are probably the result of differences in methodology and criteria for patient inclusion. Imbalance in muscle strength commonly refers to abnormal bilateral asymmetry (between homologous groups) and a disruption of the agonist-antagonist ratio. Some authors who focus on a history of hamstring or adductor strains have demonstrated the frequent abnormality of muscle strength and balance by means of isokinetic assessment. Mixed ratios, combining the eccentric performance of “decelerating” muscles (such as the hamstrings) and the concentric performance of “mobiliser” muscles (such as the quadriceps) are suggested and seem relevant. An increased emphasis on eccentric strengthening exercises, particularly for the hamstrings, and ratio correction on the basis of statistically selected cut-offs, significantly reduces the recurrence rate of the injury and lingering complaints upon return-to-sport. Similarly, isokinetic interventions, as a preseason screening tool in sports where there is a high rate of muscle strain injuries, could detect imbalances early and thus promote a preventive strategy.

A history of muscle injury represents a predominant risk factor for future insult in that muscle group. The high frequency of re-injury and persistent complaints after a hamstring strain comprise major difficulties for the athlete on return to athletic activities. Some of the risk factors associated with the possible recurrence of the injury are, in all probability, already implicated in the initial injury. One can distinguish between those events peculiar to the sport activity modalities (extrinsic factors) and other contributing factors based on the athletes individual features (intrinsic factors). For both categories, the persistence of mistakes or abnormalities in action represent an irrefutable component contributing to the re-injury cycle. Additional factors leading to chronicity can come from the first injury per se through modifications in the muscle tissue and possible adaptive changes in biomechanics and motor patterns of sporting movements. We emphasise the role of questionable approaches to the diagnosis process, drug treatment or rehabilitation design. To date, the risk factors examined in the literature have either been scientifically associated with injury and/or speculated to be associated with injury. In this context, quantifying the real role of each factor remains hypothetical, the most likely ones corresponding to inadequate warm-up, invalid structure and the content of training, muscle tightness and/or weakness, agonist/antagonist imbalances, underestimation of an extensive injury, use of inappropriate drugs, presence of an extensive scar tissue and, above all, incomplete or aggressive rehabilitation. Such a list highlights the unavoidable necessity of developing valid assessment methods, the use of specific measurement tools and more rigorous guidelines in the treatment and rehabilitation. This also implies a scientific understanding as well as specifically qualified medical doctors, physiotherapists and trainers acting in partnership. [less ▲]

Objective. To establish the inter-session reproducibility of isokinetic concentric strength and fatigue profile of the elbow flexors and extensors in sedentary women. Methods. Forty healthy women who were physically inactive or engaged in recreational sports were included in the study. Strength was evaluated at 60 and 180 degrees/s. The fatigue protocol consisted of 30 maximal-intensity elbow flexion and extension at 180 degrees/s. Results. The extensors were stronger than flexors while no dominance effect was apparent. In addition the work output of the extensors during the fatigue protocol was larger than the flexors', the previous being more fatigue resistant. A dominance effect was observed for the extensors in the fatiguing protocol. Reproducibility expressed by the coefficient of variation was less or equal to 11%. Conclusions. This study highlights satisfactory reproducibility of isokinetic strength and fatigue parameters. The values derived may be useful for interpretation of clinical tests or characterization of pathological states in women with similar characteristics. [less ▲]
