hemodynamic effects of supervised calf Muscle Exercise in patients with venous leg ulceration a prospective controlled study
Archives of Surgery, 2001Co-Authors: Konstantinos T DelisAbstract:Hypothesis Because more than two thirds of patients with venous ulcer have an impaired calf Muscle pump, enhancement of its ejecting ability with physical training may generate an improved hemodynamic milieu sufficient to promoting ulcer healing. This study evaluated the effects of short-term supervised calf Exercise on calf Muscle pump function and venous hemodynamics in limbs with venous ulceration. Design Prospective controlled study. Settings University-associated tertiary care hospital. Patients The study consisted of 2 groups. An Exercise group comprised 10 patients (median age, 72 years) receiving supervised isotonic calf Muscle Exercise for 7 consecutive days. A control group comprised 11 patients matched with those in the Exercise group for age, sex, ulcer size, and ulcer duration (all,P>.09). Patients in both groups had perimalleolar venous leg ulcers, impaired calf Muscle function (ejection fraction, Interventions After providing a complete clinical history, both groups underwent a physical examination, venous duplex scanning, and air plethysmography. The venous filling index, venous volume, residual venous volume, and residual volume fraction of the calf on standing were measured plethysmographically at baseline and on day 8, in addition to calf Muscle endurance as determined by the maximal number of plantar flexions performed against a fixed 4-kg resistance during 6 minutes (1 flexion/s). Operators were blinded to the subject's group. Exercise in the first group entailed consecutive active plantar flexions using a standardized 4-kg resistance pedal ergometer. Subjects daily completed 3 sets of flexions of 6 minutes each. All patients had short-stretched compression bandaging. Main Outcome Measures The ejected venous volume and ejection fraction were evaluated in both groups at baseline and on day 8. Results Both groups had a similar hemodynamic performance at baseline for all the variables evaluated (P>.10). After 7 days of Exercise, patients in the Exercise group improved their ejected venous volume by 67.5%, ejection fraction by 62.5%, residual venous volume by 25% (all 3,P= .006), and their residual volume fraction by 28.6% (P= .008). Changes in the control group within the same period were small (all,P>.10). By day 8, the Exercise group had a significantly better ejected venous volume (P .50) in either study group. Calf muscular endurance in the Exercise group increased 135%, from a median 153 plantar flexions at baseline to 360 on day 7 (P Conclusions By increasing the muscular endurance, efficacy, and power of the calf Muscle, isotonic Exercise improves its ejecting ability and the global hemodynamic status in limbs with venous ulceration. Prospective evaluations of the clinical effects of calf Muscle pump strengthening for the treatment of venous leg ulceration are indicated by the results of this study.

eccentric calf Muscle Exercise produces a greater acute reduction in achilles tendon thickness than concentric Exercise
British Journal of Sports Medicine, 2009Co-Authors: Nicole L Grigg, Scott C Wearing, James E SmeathersAbstract:Objective: To investigate the acute effects of isolated eccentric and concentric calf Muscle Exercise on Achilles tendon sagittal thickness. Design: Within-subject, counterbalanced, mixed design. Setting: Institutional. Participants: 11 healthy, recreationally active male adults. Interventions: Participants performed an Exercise protocol, which involved isolated eccentric loading of the Achilles tendon of a single limb and isolated concentric loading of the contralateral, both with the addition of 20% bodyweight. Main outcome measurements: Sagittal sonograms were acquired prior to, immediately following and 3, 6, 12 and 24 h after Exercise. Tendon thickness was measured 2 cm proximal to the superior aspect of the calcaneus. Results: Both loading conditions resulted in an immediate decrease in normalised Achilles tendon thickness. Eccentric loading induced a significantly greater decrease than concentric loading despite a similar impulse (−0.21 vs −0.05, p Conclusions: Eccentric loading invokes a greater reduction in Achilles tendon thickness immediately after Exercise but appears to recover fully in a similar time frame to concentric loading.

Eccentric loading induced a significantly greater decrease than concentric loading despite a similar impulse (−0.21 vs −0.05, p<0.05). Post-Exercise, eccentrically loaded tendons recovered exponentially, with a recovery time constant of 2.5 h. The same exponential function did not adequately model changes in tendon thickness resulting from concentric loading. Even so, recovery pathways subsequent to the 3 h time point were comparable. Regardless of the Exercise protocol, full tendon thickness recovery was not observed until 24 h. ---------- Conclusions: Eccentric loading invokes a greater reduction in Achilles tendon thickness immediately after Exercise but appears to recover fully in a similar time frame to concentric loading.

comparison of gait before and after superficial trunk Muscle Exercise and deep trunk Muscle Exercise
Journal of Physical Therapy Science, 2015Co-Authors: Jemyung Shim, Minho BaekAbstract:[Purpose] The purpose of this study was to examine the effects of superficial trunk Muscle and deep trunk Muscle Exercise on gait. [Subjects] The subjects were 45 young adults who voluntarily consented to participate. The subjects were divided into a control group, a superficial Muscle Exercise group, and a deep Muscle Exercise group with 15 participants in each group. [Methods] Each group performed the Exercises 5 times a week for 4 weeks. A Gait Analyzer was used to measure the subjects’ gait. A one-way ANOVA was conducted for analysis between each group. [Results] After 4 weeks, the values from right heel contact to foot flat, left foot flat to heel off, right foot flat to heel off, and left heel off to toe off significantly differed among the groups. [Conclusion] The superficial trunk Muscle Exercise improved stability, such as the period of mid stance during gait. The deep trunk Muscle Exercise improved mobility, such as heel contact to foot flat and heel off to toe off during gait.

the effect of superficial trunk Muscle Exercise and deep trunk Muscle Exercise on the foot pressure of healthy adults
Journal of Physical Therapy Science, 2015Co-Authors: Jemyung Shim, Seung NamkoongAbstract:[Purpose] The purpose of this study was to analyze the effect of superficial trunk Muscle Exercise and deep trunk Muscle Exercise on the foot pressure of healthy adults. [Subjects] The subjects were 30 healthy females and males who agreed to participate in this study. There were two groups, a superficial trunk Muscle Exercise group and a deep trunk Muscle Exercise group, with 15 participants in each. [Methods] The Exercises were conducted 5 times a week for 4 weeks for both groups. A gait analyzer was used to measure foot plantar pressure while walking on a plate. Participants were measured before starting the Exercise and after 4 weeks. The paired t-test was used to analyze the pre-and post-test results. [Results] There were no significant differences in foot pressure in any region in the superficial trunk Muscle Exercise group. In the deep trunk Muscle Exercise group, there were statistically significant increase in F1, F4, F5, R1 and R3. In addition, there were significant decreases in R2 and R4. [Conclusion] After the 4-week deep trunk Muscle Exercise group decreases in foot pressure on the inner foot and increases on the outside of the feet indicate normal and overall even distribution of body weight on the feet.
