Extracorporeal Shock Wave Therapy as Regenerative Medicine in Knee Osteoarthritis: Pre-Experiment for Matrix Metalloproteinase-3 Evaluation.

BACKGROUND: Knee osteoarthritis (KOA) is currently treated by regenerative therapies that aim to inhibit arthritic degeneration. Extracorporeal shock wave therapy (ESWT) is one of the physical regenerative approaches used for KOA management. However, little is known regarding the impact of shock wave treatment on matrix metalloproteinase-3 (MMP-3), which is one of the enzymes mediating cartilage degradation. OBJECTIVES: To evaluate the effect of ESWT on MMP-3 levels and pain intensity in patients with KOA. METHODS: Fourteen patients diagnosed with Kellgren Lawrence, grades 2 and 3 KOA were recruited for the study. ESWT piezo shockwave was applied once a week for six weeks. MMP-3 levels in the blood were measured pre-test, mid-test (three weeks after therapy) and post-test (one week after the last session) by enzyme-linked immunosorbent assay (ELISA). The perceived pain was recorded at each session by the Wong Becker Face Scale. RESULTS: The median pre-test, mid-test and post-test MMP-3 levels were 19.92 ng/mL, 15.89 ng/mL and 18.82 ng/mL, respectively, and there were significant differences between the pre-test and mid-test, and the pre-test and post-test values (p < 0.05). The pain scores also decreased significantly over the period of intervention. CONCLUSION: MMP-3 levels decreased significantly in KOA patients after ESWT, and the decline was most obvious after 3 weeks of therapy. Therefore, EWST should be considered as a suitable treatment option for KOA.

The Relationship Between Patient Factors and Clinical Outcomes of Free Functional Muscle Transfer in Patients with Complete Traumatic Brachial Plexus Injury.

Purpose: Traumatic brachial plexus injury (TBPI) causes severe disabilities to the patients, affecting not only upper limb function but also the psychosocial and economic aspects. Free functional muscle transfer (FFMT) is one of the reconstruction modalities for the management of TBPI. The aim of this study is to evaluate the functional outcomes and their correlation to patient factors. Patients and Methods: This is a retrospective study of 131 patients who suffered from complete TBPI (C5-T1) and were treated with the FFMT procedure to restore elbow flexion and wrist extension from 2010 to 2018 in our institution. We evaluated the active range of motion (AROM), muscle power with MRC (Medical Research Council) scale, DASH score, and complications, with a minimum of 12-month follow-up. Results: Following FFMT surgery, elbow flexion was significantly and successfully restored (MRC ≥ 3) in 75.5% of patients with an average AROM of 88.17 ± 41.29°. The wrist extension was restored in 42% of the patients with an average AROM of 20.69 ± 18.72°. There was no correlation between age, side of injury, and time to surgery with the functional outcomes. There was a weak correlation between education level, rehabilitation compliance, and elbow functional outcomes. Conclusion: FFMT is a reliable surgical option to restore elbow flexion in TBPI with a high satisfactory result. Our findings suggested that the FFMT indication is potentially expanded regardless of the patient factors.

Effects of Otago Exercise Program on serum Interleukin-6 level in older women.

Background: Otago Exercise Program (OEP) has been demonstrated to minimize the risk of falling in older adults by improving muscular strength and balance. Meanwhile, reduced IL-6 level serves as a biomarker of regular physical activity. Objective: Analyzing OEP effect on decreased IL-6 level in elderly women. Methods: This study used a randomized control trial design from October 2020 to May 2021. 26 participants were divided into a treatment group (13 participants) and a control group (13 participants). The treatment group received OEP for 8 weeks, in which the OEP was carried out 3 times during the first week. On the other hand, the control group did not get intervention. The IL-6 level was measured 2 times, before and after OEP. The measurement results were analyzed using paired t-test and independent t-test, which were declared significant if p < 0.05. Results: The participants' average IL-6 level at pretest and posttest was 4.77 ± 1.71 pg/mL and 4.57 ± 1.74 pg/mL, respectively. The IL-16 level of the treatment group at pretest and posttest was 4.22 ± 1.72 pg/mL and 3.97 ± 1.67 pg/mL, respectively (t = 1.058; 95% CI = -0.770 - 0.267; p = 0.311). Meanwhile, the IL-6 level of the control group at pretest and posttest was 5.30 ± 1.59 pg/mL and 5.16 ± 1.65 pg/mL, respectively (t = 0.382; 95% CI = -0.969 - 0.680; p = 0.709). The ΔIL-6 level in the treatment and control group was -0.25 ± 0.85 pg/mL and -0.14 ± 1.36 pg/mL, respectively (t = 0.240; 95% CI = -1.030 - 0.815; p = 0.813). Conclusion: The OEP didn't lower serum IL-6 levels after eight weeks.

Cultural validation and language translation of the scientific SCI exercise guidelines for use in Indonesia, Japan, Korea, and Thailand.

CONTEXT: Indonesia, Japan, Korea, Thailand. OBJECTIVE: To culturally validate and translate the Scientific Exercise Guidelines for Adults with Spinal Cord Injury (SEG-SCI) for use in four Asian countries. DESIGN: Systematic Review. PARTICIPANTS: N/A. METHODS: A systematic review was conducted to identify all published English- and local-language studies conducted in Indonesia, Japan, Korea, and Thailand, testing the effects of exercise training interventions on fitness and cardiometabolic health in adults with acute or chronic SCI. Protocols and results from high-quality controlled studies were compared with the SEG-SCI. Forward and backward translation processes were used to translate the guidelines into Bahasa Indonesian, Japanese, Korean and Thai languages. RESULTS: Fifteen studies met the review criteria. At least one study from each country implemented exercise prescriptions that met or exceeded the SEG-SCI. Two were controlled studies. In those two studies, relative to control conditions, participants in exercise conditions achieved significant improvements in fitness or cardiometabolic health outcomes only when the exercise intervention protocol met or exceeded the SEG-SCI. During the language translation processes, end-users confirmed that SEG-SCI language and terminology were clear. CONCLUSION: Clinical researchers in Indonesia, Japan, Korea and Thailand have implemented exercise protocols that meet or exceed the SCI-SEG. Results of high-quality studies align with the SEG-SCI recommendations. Based on this evidence, we recommend that the SEG-SCI be adopted in these countries. The cultural validation and translation of the SEG-SCI is an important step towards establishing consistent SCI exercise prescriptions in research, clinical and community settings around the world.
