Ultrasound is emerging as an efficient significant method for measuring muscle mass in patients with liver cirrhosis. It has been applied in numerous studies as an accurate measuring tool for the muscles of the limbs. This study was conducted to assess the severity of sarcopenia in liver cirrhosis patients, through utilizing ultrasound in measuring the cross-sectional area and consequently estimating the muscle mass of both the upper and lower limb muscles, than correlating the results with hand grip strength as representative of functional status. Also, the severity of sarcopenia was correlated with conventional prognostic scores for liver cirrhosis, like Child or MELD scores and detecting its effect on the duration of hospital stay and mortality.


This study was conducted on 101 liver cirrhosis patients who were admitted to the internal medicine hospital, 30 healthy participants were added as a control group. Using the FNIH (Foundation for the national Institutes of health) cuff off of hand grip (< 26 kg in male and < 16 kg in female, Quadriceps muscle index cutoff was estimated to be(1.67 cm/m2 for male and 1.58 cm/m2 for female).

Ultrasound (mid upper arm, mid-thigh and Quadriceps muscle index) showed significant indirect correlation with (Child even in Child A and MELD) scores, as well as with the duration of hospital stay. Also, they showed a direct correlation with HGS.


Sarcopenia in cirrhotic patients assessed by ultrasonography of (mid upper arm, mid-thigh muscle thickness) and HGS are independent predictors of disease severity and poor outcome, which is assessed by high Child and MELD scores. Also, ultrasound and HGS are straightforward bedside techniques used for assessment of sarcopenia.


Skeletal muscle is the amplest tissue within the anatomy in adults, in keeping with the Davis law (the corollary to the Wolff law for bone), muscles are generally remarkably plastic, with the flexibility to achieve or lose tissue playing on several factors. Muscle depletion commonly occurs with aging, chronic disease, and disuse, but may go unrecognized by clinicians [1].

Sarcopenia, first proposed by Irwin Rosenberg in 1989, is characterized by a progressive loss of muscle mass and is related to chronic disease. It reduces muscle strength and performance [1].

Sarcopenia—broadly defined as a significant loss of muscle mass and function—is increasingly identified as a crucial independent risk factor for varied adverse outcomes. These negative outcomes include physical disability, osteoporosis, fractures, prolonged hospital stay and re-admission. Subsequent, operational definitions also incorporate functional criteria (e.g., low muscle strength measured by hand grip strength) [2, 3].

In cirrhotic patients, it was reported that loss of rectus femoris muscle cross-sectional area (CSA) was encountered due to increased protein turnover and an imbalance between muscle protein synthesis and protein degradation. From a conceptual point of view, muscle mass assessment in these patients may help detect at-risk patients and predict the patient outcome. Furthermore, monitoring muscle mass may allow physicians to successfully identify patients who would benefit the foremost from tailored nutritional interventions [4, 5].

The diagnostic criteria for sarcopenia don't seem to be yet uniform. The diagnostic index for sarcopenia includes muscle mass, muscle strength (usually reflected by hand grip strength) and physical performance (usually reflected by gait speed) [2, 6].

Because muscle mass is considered to be one of the most important parameters for grading sarcopenia, its measurement techniques have received widespread concerns. The mostly used are Dual-energy X-ray absorptiometry (DXA) and bio-electrical impedance analysis (BIA). Computed tomography (CT) and magnetic resonance imaging (MRI) are nominated as the gold standard for assessing muscle mass because they clearly show the tissue structure. However, Ultrasound, being convenient and pocket-friendly, is usually recommended. Although the literature and guidelines suggest that the gold standard for muscle mass testing is CT or MRI, these two methods have some limitations, they're time-consuming expensive, and need specialized equipment, also CT has ionizing radiation hazards, because of these limitations, the employment of CT and MRI as a measuring tool for the muscle mass within the elderly has not yet peaked [7, 8].

When the target sarcopenic population is expected to be frail, elderly, and immobile, the imaging technique must be easily accessible, both geographically and physically, cheap, simple and can be done along the bedside, thus, rendering ultrasound a clearly better option than the previously mentioned modalities, specifically, as it offers a non-invasive, portable, and safe imaging technique, whilst having the extra benefits of maintaining image clarity, being widely utilized in medicine, familiar to clinicians, reliable and simply interpreted by the lay sonographer [9, 10].

However, several questions remain. First, should (or can) sarcopenia be diagnosed in single or composite anatomic sites, and second, which site or sites should be used? the selection of site, especially if only one peripheral site is employed, should otherwise be an appropriate surrogate marker of broader muscle mass, particularly appendicular muscle mass (ASM) or total muscle mass (TMM). However, evidence that ultrasound can accurately predict whole-body muscle mass is insufficient and it must be considered that not all peripheral muscles decline alike. As such, prediction equations for TMM (and ASM) from ultrasound-derived sites need further validation [11,12,13].

Measurement of the (quadriceps) rectus femoris (RF) cross-sectional area (CSA) is widely used as a marker for muscle size in clinical research. The rationale for these measures can be explained by its tolerability by participants, easily accessible position, simple method in acquiring its location accurately, and robust association with functional strength [14].

With ultrasound increasingly used as a good and valid muscle-imaging tool in liver cirrhosis, ultrasound based measurements cut-off points are progressively needed for both sexes, to assess the condition of an individual’s muscle, as well as help early and accurate detection of sarcopenia, this might help distinguish those at greater risk and aid in targeted treatment programs [14].

Few studies have focused on the importance of assessing upper limb muscles using ultrasound. For a far better understanding of the biceps muscle thickness (MT), cross-sectional area (CSA) and fat thickness (FT) measured by ultrasound in sarcopenic patients, a comparative analysis was performed between FT, MT, CSA of biceps, muscle mass, grip strength against the severity of sarcopenia [2].

The muscle thickness of the forearm was also significantly correlated to the grip strength [15]. Positive correlations between CSA of the biceps brachii and SMI or grip strength were observed in both genders.

Therefore, there's an urgent need for a customary and uniform measurement of sarcopenia. Ultrasound is universally accustomed diagnose and follow-up within the clinic. It can distinguish muscle tissue from subcutaneous fat and show the thickness and cross-sectional area of muscle. It's a convenient, reliable and non-radiative technique, and might be performed at the bedside for those that cannot cooperate with DXA, CT or MRI. Compared with the above methods, the appliance of ultrasound is more common, and lots of people are more willing to just accept the ultrasound examination, which contains a great prospect within the application for sarcopenia. It's been got wind as a good method to assess muscle mass within the elderly [16].

The Foundation for the National Institutes of Health Sarcopenia Project [5] recommends specific cutoff points to spot populations with functional limitations related to sarcopenia. These evidence-based criteria recognize measures of low muscle strength (i.e., grip strength < 26 kg for men and < 16 kg for women) and low lean body mass (i.e., appendicular lean mass adjusted for body mass index [BMI; weight in kilograms divided by the square of height in meters] < 0.789 for men and < 0.512 for women) [14]. These criteria were validated as predictive of future mobility impairment with a 3-year clinical follow-up [14], and this definition of muscle weakness appears to be a treatable symptom of sarcopenia [15].

The purpose of this study was to validate the utilization of ultrasound measurement as a measure of muscle mass and predictor of sarcopenia in liver cirrhosis patients and its relevance conventional prognostic scores for liver cirrhosis, like (MELD) scores similarly as detecting its effect on morbidity and mortality.


The current study was an observational prospective study conducted during the period from November 2018 to December 2020, 101 patients with liver cirrhosis and 30 control participants, to validate and emphasis the role of ultrasound measures in assessing the severity of sarcopenia and help in management of liver cirrhosis.

The ethics commission of our institution approved this study and written consent for this study from all patients before enrollment was obtained.


The study included 101 liver cirrhosis patients.

The inclusion criteria included the following:

  • Adult patients previously diagnosed to possess liver cirrhosis, either by biopsy or abdominal ultrasound (based on the morphological characteristics of cirrhosis, including hepatic contour, texture, and also the presence of portal collaterals)

  • Admitted to the hospital by a complication of liver cirrhosis (hematemesis, spontaneous bacterial peritonitis, hepatic encephalopathy, hepatorenal syndrome).

The exclusion criteria included the following:

  • History of organ failure, which interferes with nutritional status e.g. end stage nephrosis on hemodialysis, coronary failure, and respiratory failure).

  • Malignancies and hepatocarcinoma

  • Acute liver cell failure.

All patients were submitted to the following:

Patients were fully informed about the risks and benefits of the radiological procedures; they were also informed about research plan. Consent was obtained from every patient prior to participating in the research.

    The severity of cirrhosis was classified in keeping with the Child–Pugh and MELD score.

Imaging procedure

Ultrasound study

Patient position

Supine with flexed relaxed lower limbs and supinated upper limbs.

Ultrasound technique

Muscle layer thickness was assessed as a sign of nutritional status and of fat free mass (FFM). It was absolutely measured using B-mode HDI-5000 ultrasound machine (Philips HD11XE) with a broad-band linear array transducer and at a frequency of 5–7.5 MHz.

Image acquisition and measurement method

The muscle thickness was measured on each side without compression at the following two points: (Figs. 1 and 2).

  1. 1.

    Anterior mid arm point (Fig. 1): this point was determined at the flexor surface of the arm while the forearm is supinated, corresponding to the point located midway between the tip of the acromion and tip of the olecranon. The thickness of the flexor compartment was measured between the superficial fat-muscle interface and cortex of the humerus.

  2. 2.

    Anterior mid-thigh point (Figs. 2 and 3): with the knee extended, the midway point between the tip of the greater trochanter and also the lateral joint line of the knee was identified and also the thickness of the quadriceps muscle group between the superficial fat-muscle interface and the cortex of the femur was measured anteriorly. After identifying the muscle tissue, the thickness of the quadriceps muscle was obtained by measuring the space between the cortex of the femur and therefore the most superficial muscular fascia (Fig. 2). This measurement site determined using a measuring tape and analyzed so as to seek out the foremost reliable point.

  3. 3.

    Also, quadriceps muscle index was calculated as sum of both muscle thickness RT and LT cm/height2 (m2).

Measurements were performed by Applying maximal compression on the ultrasound probe without inflicting pain, in-order to forestall the underestimation of muscle wasting linked to subcutaneous edema. The effectiveness of the technique had been previously demonstrated in edematous patients.

The scanning procedure itself was deceptively simple; the difficulties raised when it involved interpreting the image to work out muscle thickness at the site(s) of measurement. The interface between fat and muscle is difficult to differentiate, because the resistance of those tissues were somewhat similar, and that they produce a weaker echo compared with one that will include interface with bone tissue.

Assessment of muscle function

Hand grip strength (HGS)

It was measured using the hand grip dynamometry shown in Fig. 4. The patient's data within the type of age and sex were entered then the patient was asked to use his maximum effort to grip both handles of the dynamometer together. The test was repeated for 3 times for every hand separately then the best record value was used as an indicator of patient’s performance.

Correlation of the ultrasound analysis and HGS

Comparative analysis was done between the Ultrasound findings with the muscle function using the Hand Grip strength (HGS), then the results were correlated with the normal cut off values for age and sex, as outlined within the results.

Statistical methods

Data were coded and entered using the statistical package for the Social Sciences (SPSS) version 25 (IBM Corp., Armonk, NY, USA). Data was summarized using mean and variance for quantitative variables and frequencies (number of cases) and relative frequencies (percentages) for categorical variables. Comparisons between groups were done using unpaired t test when comparing 2 groups and analysis of variance (ANOVA) with multiple comparisons post hoc ergo propter hoc test when comparing over 2 groups (Chan 2003a). For comparing categorical data, Chi square (χ2) test was performed. Exact test was used instead when the expected frequency is a smaller amount than 5 (Chan 2003b). Correlations between quantitative variables were done using Pearson correlation (Chan 2003c). P-values but 0.05 were considered as statistically significant.


This study was conducted on 101 liver cirrhosis patients who were admitted in internal medicine hospital. In addition to 30 health participants as control group.

According to Child score, patients were divided into 3 groups;

  • Child A (6 patients) (Fig. 5),

  • Child B (20 patients) (Fig. 6) and

  • Child C (74 patients) (Fig. 7).

The hand grip and anthropometric measures in Child groups namely dry weight, BMI, Mid upper arm circumference (MUAC) differed significantly between patients and control in addition as between both groups of patients (P value < 0.001).

Peripheral muscle assessment by ultrasound

Muscle thickness at mid-upper arm, mid-thigh and quadriceps muscle index all decreased significantly in liver cirrhosis patients compared to control group, as well as between both groups of patients according to Child score.

The presence of significant difference between muscle thickness in patients group (A&B) versus controls indicates that wasting starts early within the disease course.

Severe muscle wasting, or sarcopenia is the commonest and often most hidden complication in patients with cirrhosis, which negatively impact survival, quality of life, and response to stressor, like infections and surgeries. Patients with malnutrition and/or sarcopenia have longer hospital stay and increased in-hospital mortality [15].

Sarcopenia is related to high morbidity and mortality in healthy older adults and patients with chronic diseases [15] and is a common risk factor for frailty, falls, and fractures. The tests as CT and DEXA are costly, of limited availability, require trained personnel, and expose the patient to radiation. Therefore, it is recommended to have new methods developed to facilitate the diagnosis of sarcopenia [10]. The prevalence of sarcopenia among patients with early-stage cirrhosis is of clinical importance because its relation to increase mortality and complications [5].

Our study demonstrated that US can be used as a reliable and valid method for the evaluation of muscle mass by measuring the muscle-CSA in cirrhotic patients. Our results demonstrated that sarcopenia can be diagnosed with a rapid imaging test that's simple to perform, easily interpreted and available at the bedside.

Ultrasonography (USG) is emerging as a promising tool in measuring muscle at the bedside by quantifying the layer thickness of a muscle or muscle group of interest as an indicator of nutritional status [17]. Quadriceps muscle thickness detection by ultrasound has been recently proposed as a better bedside tool to assess sarcopenia [18].

In our study ultrasound mid upper arm, thigh and quadriceps muscle index showed significant correlational statistics (P value > 0.001) with disease severity assessed by (Child, MELD) scores. Also, ultrasound parameters showed direct correlation with muscle function assessment by HGS. So, consequently, the lower the muscle thickness (mid upper arm, quadriceps muscle) the more disease severity, and the more the patient was malnourished and also the lower HGS.

In agreement with our study [19] showed a prospective study, which was conducted using ultrasound measurement of quadriceps muscle layer thickness (QMLT) in 93 adult patients assessed for liver transplant.

These measures were compared to MELD scores, and HGS. Lower QMLT was related to decreased HGS, with (P = 0.001). Also results the same as our study which had person correlation (males) of QMLT with Na-MELD (P = 0.001) and our study had significant indirect correlation between QMLT and MELD.

They found a direct correlation between SMI and TPI (P < 0.001). The AUC for TPI considering sarcopenia by SMI was 0.79.) and this correlation accept as true with our study but we used quadriceps thickness index without pressure and we found a correlation between psoas muscle index and quadriceps thickness index with high sensitivity and specificity on ROC curve with AUC 0.9.

To our greatest knowledge we used muscle function (cut off value of hand grip < 26 kg in male and < 16 kg in female to detect stop value of muscle thickness by ultrasound mid upper arm, mid-thigh and quadriceps index on ROC curve. It showed high sensitivity and specificity. With AUC about 0.9.

HGS is considered as a noninvasive, simple and quick method can be employable in clinical and epidemiological studies [20, 21].

This study [22] suggested that in early stages of cirrhosis, muscle strength measured by HGS should be accustomed to evaluate for malnutrition and sarcopenia. Among patients with cirrhosis, 88% were Child–Pugh A and only 12% were Child–Pugh B evaluated for handgrip strength (HGS) in out-patients clinic (n = 50) and followed for 1 year to verify the incidence of major complications, the requirement for transplantation, and death. Among these, prevalence of malnutrition was 63% by HGS (P < 0.05) and this resonates with our study that HGS significantly correlated with NRS and low HGS started early even in Child A. HGS, predicted a poorer clinical outcome in patients with cirrhosis because major complications developed in 65.5% of malnourished sarcopenic patients versus 11.8% of well-nourished ones (P < 0.05).

HG was the sole technique that predicted a major incidence of major complications in 1 y in undernourished cirrhotic patients so HGS is easy noninvasive method is employed in an early stage like in Child A to detect sarcopenia and to forestall complications.

In our group of patients nearly 86.1% of our patients were sarcopenic as evidenced by hand grip strength using FNIH bring to a halt value (< 26 kg in male and < 16 kg in female) [23], being worst with increasing severity of the disease.

In our study, HGS was positively correlated with anthropometric measurement NRS for nutritional assessment, and negatively correlated enceinte score, and with mortality risk (MELD score) with (P value > 0.001).

In agreement with [24] study which was supported by the PG-SGA and NRS 2002, which assessed malnutrition and screen for nutritional risk, respectively. They found a powerful correlation between HGS and nutritional status in elderly inpatients at hospital admission, lower HGS was related to malnutrition nutritional risk and sarcopenia status with (P value < 0.001), and HGS was a stronger predictor of nutritional status.

Also, another study [25]. found that hand grip strength correlated with nutritional status, which was measured employing a Patient-Generated Subjective Global Assessment (PG-SGA) questionnaire, and these factors are often used as nutritional status predictors and nutritional status changes (P < 0.01, r = 0.292). Most subjects were observed prospectively for 3 weeks. Changes in hand grip strength correlated with nutritional status changes (P = 0.002 and r = 0.767).

Affirmed by the study [26], 80 patients with alcoholic disease with a mean MELD score of 10.50 ± 2.67 were followed for 3 months. Eleven patients died during follow-up. A significant correlation was noted between HGS and Child–Pugh score (P ≤ 00,012) and MELD score (P ≤ 0001). Mean HGS was significantly lower in patients who died during follow-up (18.04 ± 4.82 in deceased vs. 24.23 ± 5.86 in survivors, P = 0001).

Another study showed similar results, which prospectively evaluated 100 patients. All were also assessed for the severity of liver cirrhosis and mortality risk by (Child& MELD) scores and HGS. HGS mean values were significantly lower, with increased cirrhosis severity as estimated by (Child and MELD) scores with (P value = 0.012) [27].

In contrary to our results, a study by [28] showed no correlation between HGS and Child classification. They included patients who were mostly with compensated liver cirrhosis (91 of 129 patients were Child A, 27 were Child B, and only 9 were Child C). They tested the non-dominant hand and showed that HGS failed to significantly decreased with increased severity of liver cirrhosis with (P = 0510).

The discrepancy between the results of those studies (ours, 28, 27 vs. 29.) may come from the actual fact that HGS was tested within the dominant hand, while [28] examined the non-dominant hands.

One study agreed with the study [29], which was prospective analysis conducted on 176 hospitalized patients with cirrhosis, which found a mid-arm circumference (cm) significantly direct correlation with the severity of the disease. 4% of their patients were Child–Pugh C and 59% had ascites.


  1. 1.

    The foremost patients admitted in our hospital who have complications like hematemesis, coma, SBP, et al. because of hepatic decompensation are of CHILD C group so patients of CHILD A and B patients are less in number. And most of CHILD C group patients have critical case so we stabilized the patients first.

  2. 2.

    Overflow of patients within all specialties in our hospital makes using ultrasound for limited number of hepatic patients not all unlike other institutes which are specialized in hepatology.

  3. 3.

    There are no normal values for muscle thickness among Egyptians (normal general population) by ultrasound measures.

  4. 4.

    We didn’t follow up patients after discharge for quality of life, readmissions and post hospital mortality.

  5. 5.

    Significant lower leg edema may present a limitation in ultrasound assessment of thigh muscle.


  1. 1.

    We used US to assess muscle thickness also we used HGS to assess muscle function.

  2. 2.

    To our greatest knowledge this is often the primary study using HGS to line cutoff value of muscle thickness by US.


The assessment by ultrasound of the quadriceps muscle thickness likewise because the mid arm point reveals good intra- and inter-observer reliability and constitutes an accurate bedside method to diagnose and monitor sarcopenia in cirrhotic patients.

Correlation of ultrasound with HGS is an independent predictor of liver disease severity and poor outcome which are assessed by high Child and MELD score TPI is an efficient index for the assessment of muscle depletion in cirrhotic patients.

Finally, Ultrasound assessment of sarcopenia may allow monitoring the patients’ nutritional status over time in a straightforward, bed-side and reproducible manner.
