RESUMO
Objective:To investigate the clinical value of high-frequency ultrasound combined with virtual touch tissue imaging and quantification in the assessment of limb muscle tension after stroke in patients.Methods:A total of 31 patients with stroke who received treatment in Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from January 2020 to May 2022 and 41 healthy controls who concurrently underwent physical examination in the same hospital were included in this study. Before rehabilitation treatment, the shear wave velocity of the main muscle groups of the limbs was measured using virtual touch tissue imaging and quantification in all participants. The shear wave velocity of the main muscle groups was compared between the affected and healthy sides of patients between two sides of patients. The patient's muscle tension was evaluated using the modified Ashworth Scale. The shear wave velocity of the affected muscle groups in patients was correlated with the modified Ashworth Scale score.Results:There were no significant differences in the shear wave velocities of the main muscle groups of upper (biceps, flexor digitorum sublimis, flexor digitorum profundus) and lower [medial head of the gastrocnemius muscle, lateral head of the gastrocnemius muscle] limbs between the left [(2.46 ± 0.26) m/s, (2.81 ± 0.50) m/s, (2.96 ± 0.31) m/s, (2.49 ± 0.44) m/s, (2.21 ± 0.20) m/s] and right [(2.42 ± 0.29) m/s, (2.80 ± 0.47) m/s, (3.02 ± 0.36) m/s, (2.54 ± 0.37) m/s, (2.18 ± 0.17) m/s] sides in healthy controls ( t = 0.78, 0.04, 0.83, 0.58, 1.15, P = 0.435, 0.967, 0.405, 0.558, 0.216). The shear wave velocities of the main muscle groups of upper [flexor digitorum sublimis (3.74 ± 0.67) m/s, flexor digitorum profundus (3.64 ± 0.60) m/s), biceps (3.63 ± 0.64) m/s] and lower [medial head of the gastrocnemius muscle (3.28 ± 0.61) m/s, lateral head of the gastrocnemius muscle (2.90 ± 0.37) m/s] limbs on the affected side in patients with stroke were significantly higher than (2.56 ± 0.40) m/s, (2.67 ± 0.38) m/s, (2.78 ± 0.41) m/s, (2.30 ± 0.21) m/s, (2.25 ± 0.23) m/s on the healthy side ( t = 11.81, 8.21, 8.75, 8.91, 10.43, all P < 0.001). The shear wave velocities of the main muscle groups of the upper (flexor digitorum sublimis, flexor digitorum profundus, and biceps) and lower (medial head of the gastrocnemius muscle and lateral head of the gastrocnemius muscle) limbs were positively correlated with the modified Ashworth Scale score ( r = 0.77, 0.70, 0.72, 0.74, 0.78, P = 0.007, 0.029, 0.021, 0.016, 0.001). Conclusion:Monitoring the shear wave velocities of the main muscle groups of the upper and lower limbs using high-frequency ultrasound combined with virtual touch tissue imaging and quantification can effectively reflect the change in limb muscle tension of patients with stroke, which is highly valuable for evaluating rehabilitation efficacy and prognosis in patients with stroke.
RESUMO
Objective:To investigate the value of abdominal ultrasound in the diagnosis of postpartum diastasis of the rectus abdominis muscle (DRA).Methods:A total of 300 pregnant women who received prenatal examination and finally gave birth in Wenzhou Hospital of Integrated traditional Chinese and Western Medicine between October 2018 and October 2020 were included in this study. All of them underwent finger test and high-frequency ultrasound to determine the degree of DRA. The occurrence of DRA was recorded. The efficacy of abdominal high-frequency ultrasound versus finger test in the diagnosis of DRA was analyzed. The high-frequency ultrasound outcomes regarding DRA distance at different positions and at different phases were compared between women with DRA and those without DRA. Results:The overall incidence of DRA among all women included in this study was 57.67% (173/300). The incidence of DRA in multiparae was significantly higher than that in primipara [73.38% (102/139) vs. 44.10% (71/160), χ2 = 26.20, P = 0.001). The incidence of DRA in women subjected to cesarean section was significantly higher than that in women subjected to vaginal delivery [68.52% (74/108) vs. 51.56% (99/192), χ2 = 8.14, P = 0.004). The sensitivity, specificity and accuracy of abdominal ultrasound in the diagnosis of DRA were 99.42%, 98.42% and 99.00%, respectively, which were significantly higher than those of finger test [80.35%,85.04%, 82.33%, χ2 = 34.61, 15.00, 49.23, all P < 0.01]. The DRA distances at different positions measured at 36 weeks of gestation and 2 weeks postpartum were significantly shorter in women with DRA than those without DRA ( t = 5.17-7.46, P < 0.001). Conclusion:Abdominal ultrasound is of high clinical application value in the early diagnosis and rehabilitation treatment of postpartum DRA.
RESUMO
Objective:To investigate the effects of ultrasound-guided adductor block with chloroprocaine combined with fentanyl on analgesia and early rehabilitation after total knee arthroplasty.Methods:Eighty-eight patients who underwent total knee arthroplasty in Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine between June 2018 and June 2020 were included in this study. They were randomly divided into control and study groups, with 44 patients per group. The control group was subjected to distal adductor block with ropivacaine. The study group received distal adductor block with ropivacaine combined with fentanyl. Before and after distal adductor block, resting pain response was evaluated using the Visual Analogue Scale. The success rate, onset time of block, and duration of block effect were recorded. The quadriceps femoris muscle strength, knee joint range of motion, and Hospital for Special Surgery knee score before and after block were measured. The time spent in stand-to-walk test and 10-meter walking test, and incidence of falls during rehabilitation training as well as drug-related adverse reactions were recorded.Results:There were no significant differences in resting-state and task-state Visual Analogue Scale scores post-block between the two groups ( t = 0.43, 0.46, P = 0.689, 0.644). The onset time of block and duration of block effect in the study group were (5.02 ± 0.94) minutes and (2.64 ± 0.39) minutes, respectively, which were significantly shorter than those in the control group [(7.49 ± 1.12) minutes, (7.08 ± 0.92) minutes, t = 5.73, 13.02, both P < 0.001]. There was no significant difference in block success rate between study and control groups (100.0% vs. 100.0%, χ 2 = 0.00, P = 1.000). The quadriceps femoris muscle strength, knee range of motion, and Hospital for Special Surgery knee score in the study group were (4.68 ± 0.44), (112.57 ± 9.96) o and (70.56 ± 6.84) points, which were superior to those in the control group [(4.19 ± 0.42), (101.30 ± 9.67) o,(62.47 ± 6.16) points, t = 3.42, 4.64, 6.58, all P < 0.001). The time spent in stand-to-walk test and 10-meter walking test were (7.95 ± 1.48) minutes and (4.67 ± 0.63) minutes, respectively, which were significantly shorter than those in the control group [(13.41 ± 2.05) minutes, (6.24 ± 0.77) minutes, t = 8.23, 6.74, both P < 0.001). The incidence of falls in the study group was significantly lower than that in the control group (11.3% vs. 29.5%, χ 2 = 4.47, P = 0.034). There was no significant difference in total incidence of drug-related adverse reactions between the two groups (9.1% vs. 13.6%, χ 2 = 0.45, P = 0.502). Conclusion:Distal adductor block with cloprocaine combined with fentanyl meets the requirement of short-term intensive analgesia after total knee arthroplasty, and achieves sufficient analgesia, maximum retention of motor function, rapid onset, and repaid recovery.
