Efficacy of the Multifidus Retraining Program in Computer Professionals with Chronic Low Back Pain
Leo Rathinaraj Antony Soundararajan,Sreeja Mannickal Thankappan 대한척추외과학회 2016 Asian Spine Journal Vol.10 No.3
Study Design: Randomized controlled trial. Purpose: To contrast the efficacy of two exercise programs—multifidus retraining program (MRP) and traditional back exercises (TBE)—on pain and functional disability in individuals with chronic low back pain. Overview of Literature: Low back pain is a common musculoskeletal disorder. Mechanical low back pain does not involve nerve roots. Stability of the spine is provided by the ligaments and muscles of the lower back and abdomen. Although weakness of the superficial trunk and abdominal muscles are the primary risk factors, recent studies have demonstrated the involvement of weakness and lack of control of the deep trunk muscles, especially the multifidus and transverse abdominis muscles. Therefore, exercises to restore optimal lumbar multifidus function are important in rehabilitation strategies. Methods: Thirty individuals were randomly assigned to receive TBE, where exercises focused on the superficial muscles of abdomen and low back (control, group A) and MRP, where exercises focused on the deep multifidus muscles fibers (experimental, group B). Groups were examined to find the effect of these exercises on visual analog scale rated pain (visual analogical scale) and functional disability assessed by the Oswestry disability questionnaire. The exercise program lasted for 6 weeks on alternate days, with 20 repetitions of each exercise, with each move held for 5–8 seconds. Subjects were evaluated at the start of the study and after completion of the 6-week exercise program. Results: As compared to baseline, both treatments were effective in relieving pain and improving disability (p <0.001). The MRP group had significant gains for pain and functional disability when compared to the TBE group (both p <0.001). Conclusions: Both techniques lessen pain and reduce disability. MRP is superior to TBE in reducing pain and improving function.

Adenoid cystic carcinoma presenting as an ulcer on the floor of the mouth: a rare case report
Saba Khan,Khalid Agwani,Puneet Bhargava,Sreeja P. Kumar 대한구강악안면외과학회 2014 대한구강악안면외과학회지 Vol.40 No.5
Adenoid cystic carcinoma is a rare epithelial tumour, and comprises about 1% of all malignant tumours of the oral and maxillofacial region. It is a malignant tumour which may develop in the trachea, bronchus, lungs or mammary glands, in addition to the head and neck region. Occurrences in the head and neck are mostly detected in the major salivary gland, oral cavity, pharynx and paranasal sinus where it presents as a slow growing firm nodular swelling. The aim of the article is to highlight the unique presentation of adenoid cystic carcinoma as a solitary ulcer on the floor of the mouth.

Bistable Microdevice with Electrothermal Compliant Mechanism
C. Joshitha,Chella Santhosh,B. S. Sreeja,S. Rooban,G. S. N. Koteswara Rao 한국전기전자재료학회 2022 Transactions on Electrical and Electronic Material Vol.23 No.3
The compliance mechanism plays a crucial role in the MEMS (Micro-Electro-Mechanical Systems) device design as it provides elastic body deformation through respective force and motion transmission. This paper presents, an electrothermal compliant mechanism using V-beam combo structure. Design methodology, fabrication process flow, characterization results and future scope of the proposed device are elaborated. The limited elasticity of Silicon material resulted in limited response of the fabricated device compared to the FEM tool results. Hence an extended optimization for the design structure through POLYMUMPs process is recommended to overcome the limitation. The proposed device finds an application in RF switch domain with its low power consumption feature.

Background: To evaluate the efficacy of autologous platelet-rich plasma (PRP) injections in the treatment of common shoulder diseases. Methods: The PubMed, Medline, and Central databases and trial registries were searched from their inception to July 2020 for randomized controlled trials of autologous PRP injections for shoulder diseases versus placebo or any control intervention. Preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines were followed in the selection, analysis, and reporting of findings. The primary outcome was pain intensity (visual analog scale), and secondary outcomes were changes in function and quality of life (QoL). Results: A total of 17 randomized controlled trials of PRP versus control were analyzed. From 8–12 weeks to ≥1 year, PRP injections were associated with better pain relief and functional outcomes than control interventions. PRP injections were also associated with greater QoL, with an effect size of 2.61 (95% confidence interval, 2.01–14.17) at medium-term follow-up. Compared with placebo and corticosteroid injections, PRP injections provide better pain relief and functional improvement. In subgroup analyses, trials in which PRP was prepared by the double centrifugation technique, the platelet concentration in the PRP was enriched ≥5 times, leucocyte-rich PRP was used, or an activating agent was used before application reported the most effective pain relief at 6–7 months. Conclusions: PRP injections could provide better pain relief and functional outcomes than other treatments for persons presenting with common shoulder diseases. PRP injections have a greater capacity to improve shoulder-related QoL than other interventions.
