Mild traumatic brain injury recovery: a growth curve modelling analysis over 2  years

AbstractBackgroundAn improved understanding of the trajectory of recovery after mild traumatic brain injury is important to be able to understand individual patient outcomes, for longitudinal patient care and to aid the design of clinical trials.ObjectiveTo explore changes in health, well-being and cognition over the 2  years following mTBI using latent growth curve (LGC) modelling.MethodsSixty-one adults with mTBI presenting to a UK Major Trauma Centre completed comprehensive longitudinal assessment at up to five time points after injury: 2  weeks, 3 months, 6 months, 1 year and 2 years.ResultsPersisting problems were seen with neurological symptoms, cognitive issues and poor quality of life measures including 28% reporting incomplete recovery on the Glasgow Outcome Score Extended at 2  years. Harmful drinking, depression, psychological distress, disability, episodic memory and working memory did not improve significantly over the 2 years following injury. For other measures, including the Rivermead Post-Concussion Symptoms and Quality of Life after Brain Injury (QOLIBRI), LGC a nalysis revealed significant improvement over time with recovery tending to plateau at 3–6 months.InterpretationSignificant impairment may persist as late as 2  years after mTBI despite some recovery over time. Longitudinal analyses which make use of all available data indicate that recovery from mTBI occurs over a longer timescale than is commo...

Conclusion: It appears that the knee OA pain and disability can be decreased after a dual-frequency LLLT applied to acupoints (SP9, SP10, and EX-LE2). The clinical efficacy of LLLT is highly related to the therapeutic settings of the laser apparatus; hence, more clinical trials with diffident parameter settings are needed to be further clarified.

Authors: Luo Z, Hu X, Chen C, Zhu L, Zhang W, Shen Y, He J Abstract Objective: To observe the influence of the catgut-embedding method in Du Meridian acupoint on the mental and psychological state of patients with gastroesophageal reflux disease (GERD) and analyze its possible mechanism. Methods: According to the random number table, 60 patients with GERD were randomly divided into groups of acupoint catgut embedding and Western medicine, 30 cases in each group. The acupoint group was given catgut embedment in the positive reaction points along the Du Meridian, while the Western medicine group received lansopra...
