Objective To observe the therapeutic effect of warm magnetic field combined with medium frequency electric current on lumbar intervertebral disc protrusion of old patients.Methods By retrospective analysis, 120 old patients with lumbar intervertebral disc protrusion were divided into the therapeutical group (treated with warm magnetic field combined with medium frequency electric current) and control group (treated with ultrashort wave combined with medium frequency electric current), and therapeutic effects of two groups were compared.Results There was no significant difference between the therapeutic effects of two groups ( P>0.05).Conclusion Warm magnetic field combined with medium frequency electric current is same effect as ultrashort wave combined with medium frequency electric current on lumbar intervertebral disc protrusion of old patients.

Objective To observe the management effect of pressure pain point and painful tubercle in occiput-neck part on tension-type headache (TTH). Methods 380 TTH patients were treated by palpating the central and both sides part from the external occipital protuberance to the spinous processes of neck; recording the total number and position of pressure pain points and painful tubercles; kneading, hitting and pressing all recorded pressure pain points and painful tubercles.Results After 1-6 times treatment, 283 were cured and 58 were effected. The efficiency ratio is 89.7%. Conclusion Muscle obstacle in occiput-neck part plays an important role in TTH. Massage therapy has a significant effect on pressure pain points and painful tubercle.

Objective To explore the factors related with the quality of life in the elderly patients with knee osteoarthritis. Methods 92elderly patients with knee osteoarthritis were tested with short-form 36 health survey scale (SF-36), visual analogue pain scale (VAS), 5times' movement of sit-to-stand, 10 m walking speed, 3 m timed-up and walking test. At the same time, the radiological grades of knees andthe total amount of chronic diseases were collected. Results The VAS of knee pain, the course of knee osteoarthritis, the total amount ofchronic diseases and 10-m walking speed were related with SF-36 score (P<0.01). Conclusion Knee pain, course of knee osteoarthritis, totalamount of chronic diseases and walking ability are related with the quality of life in the elderly patients with knee osteoarthritis, especiallyfor knee pain.

Objective To investigate the effect of different dosage of pulsed magnetic field on expression of platelet-derived growth factor-A (PDGF-A) in rabbits with carotid atherosclerosis after carotid endarterectomy (CEA). Methods Carotid atherosclerosis were modeled in 50 New Zealand rabbits with air-drying lesion combined with high fat feed. All animals were treated with double side carotid endarterectomy after 2 months, and were randomly divided 3 groups: 0.6 T group, 1.0 T group and the blank control. The expression of platelet-derived growth factor-A were detected with immunohistochemistry 1 month, 2 months and 3 months after CEA. Results The expression of PDGF-A in treated groups were lower significantly than that in controls (P<0.05) 2 month after CEA, and it was the lowest in 1.0 T group, lower in 0.6 T group 3 month after CEA. Conclusion The pulsed magnetic field therapy can decrease the expression of PDGF-A, which might be helpful to prevent the carotid from restenosis.

Objective To observe the clinical effect of manipulation combined with physical therapy on middle-elderly knee osteoarthritis (KOA).Methods 32 KOA patients (49 knees) were treated with manual operation, such as manipulation relaxing the end of quadriceps, triceps, surae and other manipulation method for knee joint and combined with physical therapy.Results 11 cases (18 knees) were clinical curative, 16 cases (23 knees) had good effective, 5 cases (knees) had effective. The good effective rate was 84%.Conclusion Manipulation combined with physical therapy is effective on middl-elderly KOA patients.

Objective To observe the effect of manipulation treatment on headache induced by pure pillow linea nuchae inferior adhesion muscle spasm.Methods 36 headache patients caused by pure pillow linea nuchae inferior adhesion muscle spasm were treated by manipulate the methods of finger press and palm root circle press in base on fixing Ash points according to the symptoms and physical signs.Results After 5 to 10 times by manipulation,of 36 patients,25 cases were recovery,10 cases were excellent,1 case was effective,and the excellence effective rate was 97.22%.Conclusion The manipulation treatment is effect on headache induced by pure pillow linea nuchae inferior adhesion muscle spasm;the curative effect is satisfactory and stable.

Objective To observe the effect of multidisciplinary rehabilitation on activity of daily living (ADL) and injured nerve function of old stroke patients.Methods 78 old stroke patients were randomly divided into the simple rehabilitation group (36 cases) and multidisciplinary rehabilitation group (42 cases). The patients of the simple rehabilitation group were treated with Bobath method only, those of the multidisciplinary rehabilitation group were added with acupuncture and Chinese herbs. The treatment course of two groups was 6 weeks. All patients in two groups were assessed with Modified Brathel Index (MBI) for ADL before treatment and every week after treatment and the evaluation of National Institute of Health Stroke Scale (NIHSS) was also performed for injured nerve function at same times.Results After 3 weeks treatment, the scores of MBI and NIHSS of all patients improved, but there was no significant difference compared with that before treatment ( P>0.05). After 6 weeks treatment, the NIHSS scores of the patients in the multidisciplinary rehabilitation group was significant superior to that before treatment ( P<0.05), the MBI scores was also superior to that before treatment ( P<0.01); while, the NIHSS and MBI scores of the patients in the simple rehabilitation group also improved compared with that before treatment, but no significant difference ( P>0.05).Conclusion Both multidisciplinary rehabilitation and simple rehabilitation are all effect on ADL and injured nerve function of old stroke patients, but the effect of multidisciplinary rehabilitation is superior to that of simple rehabilitation (using Bobath method only).

ObjectiveTo determine the test-retest reliability of isometric muscle strength measurement for the lower limb with functional squat system （FSS） in elderly people. Methods20 elderly participants were measured the isometric muscle strength in 5 s of each lower limb with FSS, and retested a week later. The maximal voluntary contraction and the average strength of each lower limb were recorded. ResultsThe intraclass correlation coefficient were 0.77～0.88 (P<0.01). ConclusionIsometric muscle strength measurement of the lower limb with FSS shows acceptable test-retest reliability in elderly.

Objective To explore the relationship between the somatosensory evoked potential (SEP) diversification during operation and the short term outcome of ossification of posterior longitudinal ligament (OPLL) of cervical spine. Methods 70 OPLL inpatients from February 2008 to February 2011were included in this study. All patients received anterior cervical operation. According to the diversification of the SEP during surgery, the patients were divided into 2 groups. The preoperative and postoperative JOA scores of the OPLL patients were collected. Results There were 35 patients in the SEP no change group and 30 in SEP improved group. There was no difference in the preoperative JOA scores between them (P>0.05), but was significantly different in the postoperative JOA scores (P>0.05). Conclusion There is some relationship between the SEP diversification during operation and the short term outcome of OPLL of cervical spine.

ObjectiveTo investigate the age-related changes in grip strength of the elderly men and compare with the norms of overseas. Methods112 subjects were divided into six groups: 65～69 years old, 70～74 years old, 75～79 years old, 80～84 years old, 85～89 years old, and 90～95 years old. The grip strength was measured with Jamar dynamometer. ResultsThe grip strength of both sides were significantly moderate negative correlated to age (r=-0.681 and -0.68, P<0.001) and stepwise regression analysis showed the age was important clinical factor to consider in determining grip strength in the elderly men （R2=0.468, F=47.951, P＜0.001). The grip strength was declined significantly during the 75～79 and 85～89 years old. ConclusionGrip strength had declined in the elderly men and these losses were significantly related to age. The highest loss in men was in the age over 75. The norms of grip strength overseas were not applicable to Chinese older adults.
