Aim Musculus Gastrocnemius Tightness (MGT) has been linked with common foot and ankle pathologies. These symptoms sometimes are not severe enough for the patient to seek treatment. This study aims determine incidence rate of MGT among our clinical personnel if there is any association between MGT. Materials methods observational cross-sectional involves from Specialist Clinics at Hospital Kulim...

Spasm or contracture of the gastrocnemius muscle is predominantly responsible for the equinus deformity of the foot in cerebral palsy. Its release is therefore logical in the treatment of all cases which do not respond to conservative measures. The authors have demonstrated, by the use of metal markers and radiographic control at operation, that adequate release cannot be achieved by severance ...

PURPOSE To investigate the effectiveness of low-level laser therapy (LLLT) on gastrocnemius muscle morphology and Myod immunoexpression in a model of dorsal burn in rats. METHODS Sixteen male Wistar rats were distributed into two groups: control group (CG): rats submitted to scald burn injury without treatment and laser treated group (LG): rats submitted to scald burn injury and treated with ...

Anserine and carnosine in the muscle of growing rats were measured to explore the effect of dietary methionine. Carnosine was reduced in the gastrocnemius muscle of rats fed on a methionine-free diet. After refeeding on methionine for one week, carnosine in the muscle approached to the normal level. In contrast, anserine increased in the muscle of rats fed on a methionine-free diet. Anserine al...

[Purpose] Atrophy is a common phenomenon caused by prolonged muscle disuse associated with bed-rest, aging, and immobilization. However, changes in the expression of atrophy-related myoglobin are still poorly understood. In the present study, we examined whether or not myoglobin expression is altered in the gastrocnemius muscles of rats after seven days of cast immobilization. [Methods] We cond...

Post-tetanic potentiation of muscle contraction strength (PTP) occurs in cat soleus and gastrocnemius muscles. However, the mechanisms of potentiation are different in these two muscles. Soleus PTP is predominantly a neural event. The application of a high frequency stimulus to the soleus nerve regularly causes each subsequent response to a single stimulus to become repetitive. This post-tetani...

The aim of this work was to study the electromyographic characteristics of two ankle extensors during treadmill locomotion after hindlimb unloading. The studied muscles were the soleus which contains mainly slow fibres, and three parts (red, mixed and white) of the heterogeneous gastrocnemius. Our results showed that the cycle duration was significantly increased (+26%) after 14 days of unloadi...

This study attempted to evaluate the influence of using an unstable shoe in muscle recruitment strategies and center of pressure (CoP) displacement after the application of an external perturbation. Fourteen healthy female subjects participated in this study. The electromyographic activity of medial gastrocnemius, tibialis anterior, rectus femoris, biceps femoris, rectus abdominis and erector s...

[Purpose] The purpose of this study was to investigate the effect of gastrocnemius stretching combined with talocrural joint mobilization on weight-bearing ankle dorsiflexion passive range of motion. [Subjects] Eleven male subjects with bilateral limited ankle dorsiflexion passive range of motion with knee extended participated in this study. [Methods] All subjects received talocrural joint mob...
