This study investigated the effects of low-and high-volume strength trainings on neuromuscular adaptations of lower-and upper-body muscles in older women after 6 weeks (6WE), 13 weeks (13WE), and 20 weeks (20WE) of training. Healthy older women were assigned to low-volume (LV) or high-volume (HV) training groups. The LV group performed one set of each exercise, while the HV group performed three sets, 2 days/ week. Knee extension and elbow flexion one-repetition maximum (1-RM), maximal isometric strength, maximal muscle activation, and muscle thickness (MT) of the lower-and upper-body muscles, as well as lower-body muscle quality (MQ) obtained by ultrasonography, were evaluated. Knee extension and elbow flexion 1-RM improved at all time points for both groups; however, knee extension 1-RM gains were greater for the HV group after 20WE. Maximal isometric strength of the lower body for both groups increased only at 20WE, while upper-body maximal isometric strength increased after 13WE and 20WE. Maximal activation of the lower and upper body for both groups increased only after 20WE. Both groups showed significant increases in MT of their lower and upper body, with greater gains in lower-body MT for the HV group at 20WE. MQ improved in both groups after 13WE and 20WE, whereas the HV group improved more than the LV group at 20WE. These results showed that low-and high-volume trainings have a similar adaptation time course in the muscular function of upper-body muscles. However, high-volume training appears to be more efficient for lower-body muscles after 20 weeks of training.

“…In the literature, it is stated that atrophy and structural changes of hand muscles can be detected successfully by US [10,15]. However, we cannot find a comprehensive study about the possible relationships between sonographic IOM/IMS measurements and hand grip strength.…”

“…Hand muscle ultrasound, as being non-invasive and real-time, is a useful technique to visualize normal and pathological muscles. Neuromuscular disorders, like CTS, cause structural changes in muscles that can be visualized with ultrasound: atrophy can be objectified by measuring muscle thickness, while infiltration of fat and fibrous tissue increase muscle echo intensity [10]. The aim of this study was to examine whether decreased hand grip strength in CTS patients is associated with interosseous muscle thickness and intermetacarpal space dimensions.…”

Objectives. To investigate the correlation of the grip strength with sonographic measurement of interosseous muscle (IOM) and intermetacarpal space (IMS) of the hands in carpal tunnel syndrome (CTS) patients. Methods. A total of 96 hands of 48 female patients constituted the study group. Of those, 36 hands of 18 patients (mean age: 50.2 ± 9 years) had CTS confirmed by electro-diagnostic tests. Sixty hands of 30 healthy volunteers (mean age: 45.2 ± 9.7 years) constituted the control group. Grip strength was assessed by Jamar hand dynamometer. IOM and IMS dimensions for all hands were measured sonographically at three levels (2 nd , 3 rd and 4 th intermetacarpal; palmar side for IMS, dorsal side for IOM) by the same radiologist. Spearman and Mann Whitney U tests were used for statistical analysis. Results. The median hand grip strength was determined as 11.3 kg (min-max = 7.2-18.1 kg) in the CTS group and 19.5 kg (min-max = 7.8-30.5 kg) in the control group, with a statistical difference between the two groups (p < 0.03). In both groups, there was a positive correlation between the IOM-IMS dimensions and grip strength (p < 0.05). Sonographically, IOM-IMS measurements in CTS group were significantly lower than control group (p < 0.01). Conclusion. To our knowledge, this is the first study evaluating the correlation of grip strength and the sonographic IOM-IMS measurements in CTS patients. The muscular atrophy, which is generally a finding of advanced disease, may be revealed by sonographical measurements earlier than the physical examination findings.

“…However, this study is the largest study examining MUS in patients with CIDP. Second, several variables, such as handedness and body mass index, which can affect MUS findings and in turn the study findings were not considered in our analyses (Arts, Pillen, Schelhaas, Overeem, & Zwarts, 2010; Simon et al., 2015). Third, correlations of MUS findings with needle EMG findings should be further studied to determine more accurate cut‐off values for accurate diagnosis of denervation.…”

Quantitative muscle ultrasound is useful for evaluating secondary axonal degeneration in chronic inflammatory demyelinating polyneuropathy

IntroductionIn chronic inflammatory demyelinating polyneuropathy (CIDP), exclusion of secondary axonal degeneration is challenging with conventional methods such as nerve conduction study (NCS), needle electromyography, and nerve biopsy. Increased echo intensity (EI) and decreased muscle thickness (MT) identified on muscle ultrasound (MUS) examination represent muscle denervation due to axonal degeneration in neurogenic disorders, suggesting MUS as a new tool to detect secondary axonal degeneration in patients with CIDP.Methods EI and MT of abductor pollicis brevis, abductor digiti minimi, and first dorsal interosseous muscles were measured in 16 CIDP patients. Raw values were converted into z‐scores using data from 60 normal controls (NCs).ResultsSix of 45 muscles showed abnormally high EI and low MT, suggesting denervation following secondary axonal degeneration. These six muscles belonged to two patients with long disease history, unresponsiveness to treatment, and long interval from onset to initial therapy. There were no significant differences in EI and MT (p = .23 and .67, respectively) between the CIDP and NC groups, although NCS results revealed obvious demyelinating abnormalities in all CIDP patients, suggesting the fact that muscle structures will be preserved, and EI and MT will not change unless secondary axonal degeneration occurs in CIDP.Conclusion MUS is a promising tool for evaluating secondary axonal degeneration in patients with CIDP.
