Abstract:Background:Anterior Cruciate Ligament (ACL) tearing is a common injury among football players. The present study aims to determine the best single-dose of intra-articular morphine for pain relief after arthroscopic knee surgery that, in addition to adequate and long-term analgesia, leads to fewer systemic side effects. Methods:This clinical trial was conducted on 40 ASA-I athletes. After surgery, all participants received an injection of 20cc of 0.5% intra-articular bupivacaine. In addition, the first control group received a saline injection and 5, 10 and 15 mg of morphine were respectively injected into the joints of the second, third and fourth groups by use of Arthroscopic equipment before the Arthroscopic removal. The amount of pain based on VAS at 1, 2, 4, 6 and 24 hours after surgery, duration of analgesia and the consumption of narcotic drugs were recorded. Results:The VAS scores in the fourth, sixth and twenty-fourth hours after surgery showed a significant difference between the study groups. The average time to the first analgesic request from the bupivacaine plus 15 mg morphine group was significantly longer than other groups and total analgesic requests were significantly lower than other groups. No drowsiness complications were observed in any of the groups in the first 24 hours after injection. Conclusions:Application of 15 mg intra-articular morphine after Arthroscopic knee surgery increases the analgesia level as well as its duration (IRCT138902172946N3).
Ankle foot orthosis (AFO) is frequently used to improve gait deviations in patients with hemiplegia. AFOs prevent foot drop in the swing phase and promote heel strike in the early stance phase of gait. →What this article adds: A variety of studies have reported the AFO is an effective tool for improving the gait pattern of hemiplegia patients. This study provided some guidelines to robustly report AFO interventions, mechanical characteristic of AFOs, and efficacy of AFOs' construction techniques, testing strategies and the outcomes.
Background: X- ray images provide accurate and reliable data in different foot pathologies. However, the accompanied complications will limit its use for epidemiological studies and research purposes, especially in children. Therefore, simple, accessible, and cost- effective methods such as footprint, with a good correlation with x-ray images, are needed to help diagnose different foot pathologies. In the present study, the accuracy of footprint technique in assessing hallux valgus angle (HVA) was evaluated based on x-ray images through measuring the angle between the medial border protrusion of the foot and the hallux. Methods: In this cross-sectional study, 42 participants with symptomatic hallux valgus were recruited. HVA was measured by both x-ray imaging and footprint. The differences between the two approaches were identified by applying correlation-coefficient test and reliability, which was assessed using interclass correlation (ICC). Results: A significant correlation was found between the HVA measured by x-ray and HVA by footprints (p< 0.001), and the ICC was upper than 90%. Conclusion: Foot print is a reliable method for measuring HVA, as it was highly correlated with the HVAs obtained by x-ray imaging.
Background Hamstring shortening may have negative impacts on function and biomechanics of knee and hip joints and lumbo-pelvic rhythm. Many interventions are believed to correct hamstring to its normal length. There are several reports of impairment in postural control of patients with low back pain. The purpose of this study was to compare the effect of stretching exercise and strengthening exercise in lengthened position of the hamstring muscle on improving the dynamic balance of the person in patients with chronic low back pain with short hamstring muscles. Methods Forty-five patients with hamstring shortening who referred to physiotherapy clinic of Kermanshah university of Medical Sciences, Kermanshah, Iran were randomly allocated to the three groups; static stretching (n = 15), strengthening exercise in lengthened hamstring position (n = 15) and control (n = 15). All groups received conventional physiotherapy for low back pain and the two intervention groups received stretching exercise and strengthening exercise in lengthened position programs as well. All groups performed three treatment sessions for a week, a total of 12 sessions. For balance assessment, Y-Balance test was performed for each participant in three reach directions. To determine the important and significant variables, all variables entered a model (Generalized Estimation Equations method). Results The results indicate that based on GEE model, by controlling other variables, participants of static stretching exercise showed more improvement in balance than control group (β = 9.58, p-value = 0.014). Also, balance status showed significant improvement in the end of study compared to baseline of the study (β = 7.71, P-value< 0.001). In addition, the balance in three reach directions improved significantly and the greatest balance improvement was in the anterior reach direction (β ranged over = 6.16 to 11.59) and the height of patients affected their balance (β = 0.28, P-value = 0.034). Conclusions Group (type of intervention), phase of intervention, reach direction of test (anterior, posteromedial and posterolateral) and height of participants were associated with balance performance. Static stretching exercise was more effective than muscle strengthening exercise in lengthened position for improving dynamic balance in low back pain patients with hamstring tightness.
