Introduction Periarticular muscles have a significant role in keeping the mobility and integrity of the hip joint. The aim of this article was to investigate the effects of the total hip arthroplasty and early rehabilitation on the muscle strength. Patients Three groups of examined persons (matched in relation to musculosceletal conditions, sex, age and occupation) were included in the investigation. The first group (40 of the involved hip) and the second group (with 33 involved hips) were groups of patients with late-stage of osteoarthritis of the hip. The first group of patients was managed conservatively and the second group operatively (total cemented hip endoprosthesis was performed). The third group was control group with 123 healthy hips. Material and methods The maximal voluntary isometric strength was measured with dynamometer. The muscle strength was tested in all three groups: in the first group of patients at the beginning and at the end of the therapy and in patients of the second group 6?3 months postoperatively. Results A significant improvement of the muscle strength was noted for the flexors (t=2.45, p<0.05), musculus tensor fasciae latae (t=2.35, p<0.05), extensors (t=2.85, p<0.01), adductors (t=3.02, p<0.01), external rotators (t=3.1, p<0.01), m. gluteus medius (t=5.28, p<0.001) and internal rotators (t=5.77, p<0.001) after total hip arthroplasty and early rehabilitation in comparison to the conservatively treated group. Conclusion The muscle strength in the patients with osteoarthritis of the hip after arthroplasty was significantly higher than after rehabilitation for all hip muscles but did not reach values of the strength of the muscles in the corresponding control group.

This study aimed to determine the changes in the Gluteus medius of 4 year-old Brasileiro de Hipismo (BH) horses submitted to light physical activity for 10 months. The study involved 11 horses from the "Nove de Julho" Battalion of the Military Police of São Paulo State (PM-SP). Percutaneous muscle biopsy was performed in horses at maintenance and in those that had participated in routine police work for 10 months with the PM-SP. Fragments of the left Gluteus medius muscle was removed at depths of 20mm and 60mm. To determine the fiber types, the histochemical analyses were performed for myofibrillar adenosine triphosphatase (mATPase) and nicotinamide adenine dinucleotide tetrazolium reductase (NADH-TR). The morphometry of the fibers was performed by calculating the cross sectional area (CSA), relative frequency distribution (F) and relative cross-sectional area (RCSA). After the period of physical activity, type IIA fibers showed an increase in F and RCSA at both depths. The type I fibers showed a decrease in F at a depth of 60mm and the type IIX fibers showed no change in F at the two depths. With regard to the results for RCSA, type I and IIX fibers also did not show alterations after 10 months of light physical activity. Low intensity physical activity produced significant adaptations in the Gluteus medius muscle of horses of the BH breed, including changes in metabolic and contractile properties as evidenced by the increase in the area occupied by type IIA fibers at both depths of the biopsy.

Purpose: The clinical outcomes of total hip arthroplasty are influenced by the correct muscle function that determines good, longterm and proper function of the artificial joint. The aim of the study was to analyze the electromyographic activity of the gluteus medius muscle in patients with hip osteoarthritis and after arthroplasty in various static weight bearing conditions, both on the affected and contralateral side. Methods: The prospective study involved 70 patients qualified for hip replacement. Patients underwent a surface electromyography of the gluteus medius muscle which involved the Trendelenburg test. The normalized results were obtained for both hips, preoperatively and 6 months after arthroplasty. Results: The only muscle activity differences were found at a full load condition of lower limb. In the preoperative assessment, the activity of the gluteus medius muscle was greater on the side qualified for surgery. After arthroplasty and the rehabilitation period, the muscle activity on the operated side decreased and significantly increased on the contralateral side. Detailed analysis of the contralateral side revealed relationship with osteoarthritis. Previous hip arthroplasty of that side resulted in lower muscle activity, similar to fully functional joints. Conclusion: The activity characteristics of the gluteus medius muscle vary depending on the condition of the joint, and the characteristics change as a result of the surgical procedure performed on both the operated and contralateral sides. These dependencies should be taken into account in the rehabilitation process, especially at the side opposite to the operated one.

Abstract Background While supraspinatus atrophy can be described according to the system of Zanetti or Thomazeau there is still a lack of characterization of isolated subscapularis muscle atrophy. The aim of this study was to describe patterns of muscle atrophy following repair of isolated subscapularis (SSC) tendon. Methods Forty-nine control shoulder MRI scans, without rotator cuff pathology, atrophy or fatty infiltration, were prospectively evaluated and subscapularis diameters as well as cross sectional areas (complete and upper half) were assessed in a standardized oblique sagittal plane. Calculation of the ratio between the upper half of the cross sectional area (CSA) and the total CSA was performed. Eleven MRI scans of patients with subscapularis atrophy following isolated subscapularis tendon tears were analysed and cross sectional area ratio (upper half /total) determined. To guarantee reliable measurement of the CSA and its ratio, bony landmarks were also defined. All parameters were statistically compared for inter-rater reliability, reproducibility and capacity to quantify subscapularis atrophy. Results The mean age in the control group was 49.7 years (± 15.0). The mean cross sectional area (CSA) was 2367.0 mm2 (± 741.4) for the complete subscapularis muscle and 1048.2 mm2 (± 313.3) for the upper half, giving a mean ratio of 0.446 (± 0.046). In the subscapularis repair group the mean age was 56.7 years (± 9.3). With a mean cross sectional area of 1554.7 mm2 (± 419.9) for the complete and of 422.9 mm2 (± 173.6) for the upper half of the subscapularis muscle, giving a mean CSA ratio of 0.269 (± 0.065) which was seen to be significantly lower than that of the control group (p < 0.05). Conclusion Analysis of typical atrophy patterns of the subscapularis muscle demonstrates that the CSA ratio represents a reliable and reproducible assessment tool in quantifying subscapularis atrophy. We propose the classification of subscapularis atrophy as Stage I (mild atrophy) in case of reduction of the cross sectional area ratio < 0.4, Stage II (moderate atrophy) in case of < 0.35 and Stage III (severe atrophy) if < 0.3.

Variations in the cross-sectional area of eye muscle of carcasses cut between the tenth and eleventh ribs were investigated, using 105 Hereford and 51 Angus steers aged 20 months. These cattle consisted of three groups, born in successive years. At constant carcass weight, statistically significant differences in eye muscle area were found between breeds and between years. Breed and year differences were also found in eye muscle area with width and depth of eye muscle constant, so that there are limitations to the estimation of eye muscle area from width and depth measurements. A nomograph is given for estimating eye muscle area from width and depth for Hereford and Angus cattle, when all animals are reared in the same year and environment. The use of eye muscle area as an indicator of weight of carcass muscle is discussed.
