Ankle Plantar Flexion

The purpose of the present study was to examine genetic and environmental effects on maximal isometric handgrip, knee extension, and ankle plantar flexion strength. In addition, we wanted to investigate whether the strength of these three muscle groups shares a genetic component or whether the genetic effect is specific for each muscle group. Muscle strength was measured as part of the Finnish Twin Study on Aging in 97 monozygotic (MZ) and 102 dizygotic (DZ) female twin pairs, aged 63-76 yr. The MZ and DZ individuals did not differ from each other in age, body height, weight, or self-related health. The age-adjusted pairwise (intraclass) correlations of the MZ and DZ twins were, respectively, 0.462 and 0.242 in knee extension, 0.435 and 0.345 in handgrip, and 0.512 and 0.435 in ankle plantar flexion strength. The multivariate genetic analysis showed that handgrip and knee extension strength shared a genetic component, which accounted for 14% (95% confidence interval: 4-28%) of the variance in handgrip strength and 31% (95% confidence interval: 18-45%) in knee extension strength. The influence of genetic effects on ankle plantar flexion strength was minor and not significant. Furthermore, these three muscle groups had a nongenetic familial effect in common and nonshared environmental effects in common. The results suggested that muscle strength is under a genetic regulation, but also environmental effects have a significant role in explaining the variability in the muscle strength.

The purpose of our study was to evaluate the functional outcomes of two methods of surgical treatment of acute closed raptures of the Achilles tendon, specifically, the primary open repair and the percutaneous repair techniques, utilizing (a) isokinetic plantar flexion strength, (b) midcalf girth, (c) ankle joint proprioception, and (d) ankle range of motion values. As a secondary purpose, the frequency of reruptures and postsurgical complications were compared between techniques. Twenty male patients (mean age, 43.8 ± 9.4 years) who sustained complete, closed ruptures of the Achilles tendon participated in this study. Results of pairedttests revealed significant differences between postsurgical and contralateral normal limbs for 6 of 12 variables. Results of the ANOVAs revealed no significant differences between the open repair group and percutaneous repair group for any of the evaluative parameters. The significant deficits in postoperative isokinetic plantar flexion strength and midcalf girth measurements, irrespective of surgical technique, suggest an incompleteness of rehabilitation or, more likely, the physiological inability to regain these characteristics postoperatively.

Introduction and Aim: Diabetic Cheiroarthropathy is defined as the condition of restriction joint mobility due to pseudo-sclerodermatous hand, the fibrosis of the elastin connective tissues over the skin. It limits joint mobility especially around Tibia fibular mobility that are interrelated with the flexibility of ankle motion that results in the balance disorder in diabetic population. The aim of the study was to determine the effects of the tibia fibular mobilization technique on ankle joint in diabetes mellitus patients. Materials and Methods: 60 diabetic subjects were randomly assigned into experimental group and control, in which experimental group received Tibia fibular mobilization technique and conventional treatment whereas control group received only conventional treatment 1 time a week for 3 weeks. Results: There is no significant difference in Ankle dorsi flexion range of motion in both extremities but there is significant difference in ankle plantar flexion range of motion in both extremities and functional reach test in both extremities. Conclusion: There is a significant difference in the ankle plantar flexion range of motion and functional reach test, Hence, mobilization of Tibiofibular joint will be beneficial in improving the ankle range of motion and balance factor in the diabetic population.

Selection Of

The hingeless plastic ankle-foot orthosis (AFO) changes stiffness largely depending on how much plastic is trimmed around the ankle. To support proper selection of the orthosis and final adjustment of the orthotic stiffness, the correlation between the posterior upright width and the resistance to dorsi- and plantar flexion movements was measured in 30 posterior-type plastic AFOs. The posterior upright width was varied by regularly trimming around the ankle in nine stages. The resistance to dorsi- and plantar flexion movements was measured by bending the plastic AFOs 15d` with the measuring device described in Part 1. All the plastic AFOs decreased in their resistance to both movements in proportion to the reduction of the posterior upright width. The maximum resistance to plantar flexion movement was about 28 Nm, which was strong enough to assist dorsiflexion in patients with severe spasticity. On the other hand, the maximum resistance to dorsiflexion movement measured was about 10 Nm, which was insufficient to stabilise the ankle in patients who lacked in plantar flexion strength. These findings suggested that this type of plastic AFO should be prescribed for patients who predominantly require dorsiflexion assist, and that the orthotic stiffness could be finally adjusted by trimming to exactly meet individual requirements.

The peroneus longus tendon has been used for a graft in orthopedic reconstruction surgery due to its comparable biomechanical strength to the native Anterior Cruciate Ligament (ACL) and hamstring tendon. However, one of the considerations in choosing autograft is donor site morbidity. This study aimed to compare ankle eversion and first ray plantar flexion strength between donor site and its contralateral. Hypothesis: The study hypothesis was that the eversion and first ray plantar flexion muscle strength were different between harvest site and contralateral healthy site. Methods: From March 2017 to December 2018, patients who underwent ACL reconstruction using peroneus longus tendon autograft were included in this study. From the first day after surgery, the patients followed rehabilitation protocol. Ankle eversion and first ray plantar flexion strength were measured using a modifieddynamometer 6-months after surgery. Donor site morbidities were assessed 6 months after surgery using the Foot and Ankle Disability Index and American Orthopedic Foot and Ankle Society scoring system for ankle and hindfoot. Results: Thirty-one patients fulfilled the inclusion criteria, with 22 males and 9 females, ranging from 18-45 years of age (mean: 27.58±8.69). There was no significant difference in ankle eversion strength at donor site compared to contralateral (p=0.54) with means 65.87±7.63 N and 66.96±8.38 N, respectively. Also, there was no significant difference in ankle first ray plantar flexion strength at donor site compared to contralateral (p=0.68) with means 150.64±11.67 N and 152.10±12.16 N, respectively. The FADI score of 99.71±0.57 and AOFAS score of 98.71±3.03 were considered excellent results. Conclusion: Our study shows that donor site ankle eversion and first ray plantar flexion strengths were similar with the contralateral healthy site with no donor site morbidity. This suggests that peroneus longus tendon is a promising graft in ACL reconstruction.
