“…This experimental finding suggests that oscillatory joint mobilization up to the initial resistance could elongate the posterior capsule and lead to immediate improvement on the range of shoulder motion. In a study using fresh cadaveric shoulder, Hsu et al 8,10 reported that 5 repetitions of joint mobilization performed in the resting position did not result in immediate improvement on the range of shoulder abduction. In addition, the measured displacement change (1.10 mm) resulting from the 5 repetitions was not significant.…”

“…They tested these hypotheses with experiments on cadaveric shoulders and demonstrated immediate improvement in glenohumeral joint range of motion after joint mobilization that utilized a force matching the magnitude of the final resistance. 8,10,11 However, the study was limited in that no data were presented to examine whether the mobilization technique resulted in sustained changes to the joint or any significant tissue damage had occurred. The current study demonstrated sustained mechanical changes of the joint properties 1 hour after simulated oscillatory mobilization, as well as evidence of damage to the target tissue for some simulations of joint mobilization.…”

Study Design Experimental laboratory design. Objectives To examine the effect of force and repetition during oscillatory joint mobilizations on the posterior capsule of the glenohumeral joint. Background The optimal external force and frequency to be used during joint mobilization to elongate the posterior capsule of the glenohumeral joint has yet to be identified. Methods Twenty-one posterior capsules were harvested from fresh-frozen shoulders. A cyclic loading test simulating oscillatory posterior joint mobilization on the shoulder specimens was performed with a material testing machine. The specimens were assigned to 3 different loading groups simulating joint mobilization in the toe (5 N), transition (20 N), and beginning of the linear regions (40 N) of the load displacement curve. Displacement of the humeral head at an applied load of 5 N was recorded at the 1st, 100th, 200th, 300th, 400th, 500th, and 600th cycles and at 1 hour after completion of the cyclic loading. Furthermore, stiffness was calculated after the 1st and 600th cycles and 1 hour after testing. Results Humeral head displacement was significantly greater for the 100th to 600th cycle, compared to the 1st cycle, for all 3 loading groups. Significant increases in displacement and stiffness were observed between the 1st cycle and 1 hour after completion of the cyclic tests for both the 20-N and 40-N loading groups. Conclusion While oscillatory joint mobilization to a force of 5 N resulted in temporary elongation of the posterior capsule, mobilization to loads of 20 and 40 N resulted in sustained elongation of the capsule for up to 1 hour. Our findings also suggest that mobilization up to loads that represent the beginning of the linear region of the load displacement curve could be performed without serious damage to the posterior capsule.

“…We consider that mobilization effec- tively led to such density decreases, as the treatment group showed significant improvement. Studies using shoulder joint specimens from fresh cadavers [6][7][8] reported that mobilization (repetitive stretch stimulation) increased the range of joint motion and altered the rigidity of the joint capsule. It is possible that only the cross-linking between collagen fibers was damaged, though we did not investigate cross-linking.…”

These studies in which the effectiveness was verified by basic medical examination reported results derived only from the examination of fresh cadavers [6][7][8] , which led to incomplete understanding of the technique.…”

Abstract.[Purpose] The aim of this study was to investigate the histopathological effects of mobilization on joint components using a rat knee joint contracture model. [Method] Twenty-two male Wistar rats (aged 9 weeks) were randomly divided into an experimental group (n = 18) and a control group (n = 4). The experimental group had the right posterior limb knee joint immobilized for 8 weeks to induce contracture after which this group was subdivided into three subgroups-immobilized, treatment, and non-treatment groups. In the immobilized group (n = 6), knee joint specimens were collected immediately after immobilization. The non-treatment group (n = 6) was bred normally for 8 weeks, while the treatment group (n = 6) underwent mobilization during the same 8 weeks. After breeding, we prepared tissue specimens of the knee joint for observation in the sagittal plane and examined them using a light microscope. [Results] Compared to the non-treatment group, the treatment group showed an increase in the number of fat cells in the synovial subintima and a reduction in the density of collagen fiber bundles in the posterior joint capsule.[Conclusion] Joint mobilization appears to effectively improve joint function.

“…15,16 For example, a glide of the tibia on the femur directed anteriorly is commonly performed with the intent of improving knee extension. Although the use of glides at various joints has been shown to result in direction-specific increases in joint ROM, [17][18][19][20] we are unaware of any previous research that has evaluated the effect of an anterior tibiofemoral glide on knee-extension ROM. There is also evidence to suggest that improvements in joint ROM after manual therapy interventions can translate to changes in characteristics of walking gait.…”

Purpose: The purpose of this preliminary investigation was to evaluate the effect of anterior tibiofemoral glides on maximal knee extension and selected spatiotemporal characteristics during gait in patients with knee extension deficits after anterior cruciate ligament (ACL) reconstruction. Methods: Twelve patients with knee-extension deficits after recent ACL reconstructions underwent quantitative gait analyses immediately before and after 10 minutes of repeated anterior tibiofemoral glides on the operative limb, and again after a 10-minute seated rest period. Results: Maximum knee extension during stance phase of the operative limb significantly increased immediately after the treatment (mean increase: 2.0 e4.1 , 95% CI: 0.6 -3.3 ). Maximum knee extension decreased after the 10-minute rest period (mean decrease: 0.9 e1.8 , 95% CI: À0.1 -1.8), although the decrease was not statistically significant. Small increases in operative limb step length, stride length, and gait speed were observed after the rest period compared to baseline values only. Conclusions: A single session of anterior tibiofemoral glides increases maximal knee extension during the stance phase of gait in patients with kneeextension deficits. Increases in knee extension are small and short-lived, however, suggesting that continued activity is required to maintain the observed improvements.Key Words: anterior cruciate ligament, biomechanics, gait, knee, manual therapy RÉ SUMÉObjectif : L'objectif de cette recherche pré liminaire é tait d'é valuer l'effet du glissement du fé moro-tibial anté rieur sur l'extension maximale du genou et sur des caracté ristiques spatiotemporelles choisies au cours de la marche chez les patients affecté s d'un dé ficit de l'extension du genou aprè s une reconstruction du ligament croisé anté rieur (LCA).
