Status of the Specialty of Physical and Rehabilitation Medicine

Chinese Journal of Rehabilitation Medicine.2010;25(9):819-822. doi:10.3969/j.issn.1001-1242.2010.09.001

The objectives of this paper are to help specialists in Physical and Rehabilitation Medicine plan their careers, influence the future of the PRM specialty and advocate effectively for those with limitations of functioning. The experiences of the authors are the sources of its observations and suggestions. The senior author has had extensive national and international experience in the specialty as a clinician, teacher, researcher, manager, leader and advocate. The junior author adds the insights of one who only recently has become immersed in PRM. The following are suggestions and observations the authors believe could contribute to the future success of individual PRM specialists and the PRM specialty. ①Review and reinforce the significant accomplishments of PRM over the last 70 years. It has significantly expanded the focus of health care to include the importance of functioning. ②Identify the specialty's current strengths, weaknesses, threats and opportunities. As a clinical specialty, it has expanded nationally and internationally, yet its research contributions remain limited. The absence of an evidence base for much of its activity risks reduced support from payers, yet the population needing its services continues to expand. ③Develop strategies to increase the ability of PRM specialists and PRM to improve the lives of people with or likely to have limitations of functioning. These strategies could include sharing best practices, supporting effectiveness research and developing expert consensus guidelines. The need for physicians who are experts in the strategies of improving the lives of those with complex problems of functioning will continue to expand. This need will assure the continuation of the specialty of PRM as long as it improves the abilities of its members to help those with problems of functioning, and it advocates for those whom its members serve.

Chinese Journal of Rehabilitation Medicine.2009;24(11):1002-1005.

Objective: To analyze the influence of long-term swimming training on spatial learning-memory in rats and its relationship with cyclic adenosine monophosphate(cAMP) and cyclic guanosine monophosphate(cGMP) signal transduction pathway. Method: After 3 times adaptable swimming exercises (30min each time), 40 male SD rats were divided into 2 groups: control group (CR, n=20) and exercises, group (TR, n=20). CR group didn't swim, and TR group swam without burden (6 times/week, 60 min each time). After 8 weeks training, 10 rats were selected from both groups respectively for examing of Morris water maze test. Radioimmunoassay was used to measure the levels of cAMP and cGMP in hippocampus and prefrontal cortex of rats. Result: ①Compared with CR group, in TR group learning-memory improved in a certain extent: ②Compared with CR group, in TR group, the level of cAMP in hippocampus enhanced very obviously (P＜0.01), the cAMP/cGMP ratio enhanced obviously (P＜0.05); in prefrontal cortex the levels of cAMP and cAMP/cGMP ratio enhanced obviously (P＜0.05). Conclusion: Swimming training for 8 weeks improved the spatial learning-memory of rats in a certain extent, and elevated the level of cAMP and cAMP/cGMP ratio in hippocampus and prefrontal cortex of rats obviously. It is suggested that exercises might affect learning-memory by cAMP and cGMP signal transduction pathway.

Chinese Journal of Rehabilitation Medicine.2009;24(5):390-393.

Objective: To investigate the influence of electroacupuncture (EA) combined with repetitive transeranial magnetic stimulation(rTMS) on the temporal profile of nestin expression after induction of focal cerebral isehemia in adult rats and to explore the mechanism of EA combined with rTMS in treating ischemic brain injury. Method: The model of transient focal ischemia was produced by occlusion of middle cerebral artery. Seventy-five Wistar rats were randomly divided into normal group, model group, EA group, rTMS group and EA +rTMS group. The neurologic impairment rating and ability of learning and memory were observed at the 7th、14th and 28th d after infarction respectively. Meanwhile, Western blotting was used to observe the number of nestin expression positive cells. Result: Nestin-positive cells were found in cortex, subgranular zone (SGZ), subventricular zone (SVZ) of the ipsilateral side at different time points after cerebral isehemia. The number of nestin-positive cells peaked at the 7th d, began to decrease at the 14th d and was significantly higher in EA+rTMS group than that in model group (P<0.05), then almost reached normal at the 28th d. The improvement of neural motor function deficits as well as the indexes of learning and memory were more obvious in EA+rTMS group compared with model group (P<0.01, P<0.05). These effects were most obvious in EA+rTMS group compared with the EA and rTMS group (P<0.05). Conclusion: EA and rTMS possess the potency of building up and can increase the number of nestin-positive cells in some brain regions after focal cerebral ischemia, which might be one of the important mechanisms of EA combined with rTMS in treating ischemia brain injury.

Bin XIE ; Chun LUO ; Rongli WANG ; Ninghua WANG

Chinese Journal of Rehabilitation Medicine.2009;24(5):394-398.

Objective: To compare the balance ability between normal people and non-specific low back pain (nsLBP) patients and explore the relationship between balance ability and muscle function in nsLBP patients. Method: Ten nsLBP patients as nsLBP group and 10 age and gender-matched healthy control subjects as control group were investigated. Posturography on balance platform and surface electromyography (sEMG) were performed to assess all the subjects' function of equilibrium and muscle activities of erector spinea(ES), muhifidus(MF), abdominal external oblique (EO), hamstring (HS) and maximal gluteus (MG) bilaterally. Result: The nsLBP subjects had greater sway on anterior-posterior direction (Y-speed and Y-extension, P=0.05) on feet-together posture and bigger main axis (P=0.023) on nature standing with eyes closed when compared with controls. The iEMG ratios of right MG in nature standing (eyes closed)/ nature standing (eyes open) and feet-together (eyes open)/nature standing (eyes open) in control group were significant higher than that in nsLBP group (P=0.03 and P=0.013). Conclusion: Balance evaluation combined with sEMG measurement on trank and lower limb muscles provided some quantitative information about functional deficits such as pestural control and muscle activities in nsLBP patients. This relationship should be emphasized in prevention and rehabilitation of nsLBP.
