Treatment outcomes in post-stroke shoulder-hand syndrome: The role of combined acupuncture, traditional Chinese herb hot compress and rehabilitation training.

BACKGROUND: Acupuncture, traditional Chinese herb hot compress and rehabilitation training is useful in post-stroke shoulder-hand syndrome (SHS), but it is less commonly used in combination. OBJECTIVE: To analyse the therapeutic efficacy of a combination of acupuncture, traditional Chinese herb hot compress and rehabilitation training in SHS patients. METHOD: Patients diagnosed with post-stroke SHS and treated from January 2022 to March 2023 at Beijing Friendship Hospital and Beijing Pinggu Hospital were selected and randomly divided into three groups (A, B and C). Group A received conventional rehabilitative treatment (35 cases), Group B underwent conventional rehabilitative treatment + acupuncture (35 cases), and Group C received conventional rehabilitative treatment + acupuncture + traditional Chinese herb hot compress treatment (35 cases). The post-treatment effectiveness rate, visual analogue scale (VAS) score, activities of daily living (ADL) score, Fugel-Meyer assessment (FMA) score, SHS assessment scale (SHSS) score and shoulder joint mobility were compared among the three groups. RESULTS: The post-treatment VAS score (FVAS score= 232.512, P< 0.001), FMA score (FFMA score= 239.412, P< 0.001), ADL score (FADL score= 412.634, P< 0.001), SHSS score (FSHSS score= 212.542, P< 0.001) and shoulder joint mobility (FShoulder Joint Mobility= 197.531, P< 0.001) all showed statistically significant differences. The VAS and SHSS scores decreased in the order of Group A > Group B > Group C, while the FMA, ADL and shoulder joint mobility scores increased in the order of Group C > Group B > Group A. The post-treatment effectiveness rates (χ2= 48.510, P< 0.001) also exhibited statistically significant differences, decreasing in the order of Group C (94.29%) > Group B (82.86%) > Group A (71.43%). CONCLUSION: The treatment efficacy of the combined acupuncture, traditional Chinese herb hot compress and rehabilitation training for SHS patients is significant, warranting its clinical promotion.

Mirror visual feedback as therapeutic modality in unilateral upper extremity complex regional pain syndrome type I: randomized controlled trial.

BACKGROUND: There is growing evidence for the effectiveness of mirror therapy (MT) on pain reduction in patients with type I complex regional pain syndrome (CRPS I). AIM: To evaluate the efficacy of MT on pain reduction and hand function in subjects with unilateral upper extremity CRPS I. DESIGN: Randomized controlled trial with control group cross-over (half cross-over design). SETTING: Subjects with CRPS I were outpatients of a university hospital and cooperating centers. All patients carried out the daily exercise at home. POPULATION: Subjects with unilateral upper extremity CRPS I meeting the Budapest diagnostic criteria. METHODS: Subjects were randomly divided into two groups. Group A (N.=13) carried out a ten-minute MT exercise daily, for a total duration of six weeks. Group B (N.=14) acted as a control group for six weeks followed by six weeks of MT with the same characteristics as Group A. Upper extremity active range of motion, strength, dexterity, limb volume, affected-to-unaffected hand temperature difference, and health-related quality of life were evaluated before and after each period. Daily records on the visual analogue scale were used for pain evaluation. Effectiveness was calculated using mixed-effects modelling for between-group comparisons and within-group variability, and identification of significant predictors. RESULTS: Twenty-three females and four males with an average age of 56.1±9.6 years completed the study. Except for the affected-to-unaffected hand temperature difference, both groups consistently demonstrated significant or near-significant improvements in measured parameters after MT period. The improvements were evident upon an intergroup comparison of Group A and the control period of Group B as well as longitudinally within Group B. No significant improvement was found during the control period. CONCLUSIONS: Principles focused on mirror visual feedback to the central nervous system can sustain promising therapeutic potential as part of the treatment for pain reduction and hand function in CRPS I patients. CLINICAL REHABILITATION IMPACT: MT can be considered as part of the therapeutic regimen employed for the treatment of CRPS I.

Complex regional pain syndrome.

ABSTRACT: Complex regional pain syndrome (CRPS), formerly called reflex sympathetic dystrophy (RSD), is a chronic pain phenomenon associated with an alteration in peripheral and central pain perception in a localized body region. Because of the many risk factors associated with this phenomenon, the true nature of the disease risk and clinical course are a challenge to predict. After the diagnosis is confirmed and treatment is provided promptly, clinicians must consider patient health and function holistically to foster improvement in overall quality of life.

Feasibility analysis of combined traditional Chinese medicine fumigation and electromyography biofeedback in injured players with shoulder-hand syndrome after stroke

Objective: Exploring the feasibility of combining herbal fumigation and myoelectric biofeedback therapy in injured players with post-stroke shoulder-hand syndrome. Methods: A total of 80 players with shoulder-hand syndrome after stroke who were healed in our hospital from July 2019 to June 2021 were retrospectively opted as the research subjects, and were divided into a joint intervention cluster (JIG) according to the variations in their healing methods. cluster, n=40, receiving traditional Chinese medicine fumigation and EMG biofeedback healing) and EMG healing cluster (Electromyobiological feedback cluster, EFG cluster, n=40), the healing effect, changes in simplified FMA mark of upper limbs before and after healing, and healing effects were contrasted between the two clusters. The changes of the front and rear shoulder pain and the pain part of the High Coast Shoulder Joint Function Rating Scale were recorded, and the occurrence of adverse reactions in the two clusters of injured players was recorded; Results: The total effective rate of injured players in the JIG cluster was 97.50% (39/40), which was notably upper than 85.00% (34/40) in the EFG cluster, and the variation between the clusters was notable (P<0.05). None notable variation in the simplified FMA mark between the clusters (P>0.05).

Latent infection after spinal cord stimulation device implantation for complex regional pain syndrome: A case report.

RATIONALE: Spinal cord stimulation (SCS) is one of the invasive treatments of complex regional pain syndrome (CRPS). The positive effect has been observed for several years after implantation. However, infection is a common cause of SCS failure and device removal. PATIENT CONCERNS: Here we describe a case of latent infection at the implantable generator pocket site 9 years after SCS implantation in a patient with CRPS. DIAGNOSES: A 52-year-old patient was diagnosed with type 1 CRPS. The right foot pain was intractable with standard treatments. SCS implantation was performed and SCS worked well without complication. Nine years later, the patient revisited due to pain, tenderness, and redness at the abdominal wall for 2 weeks. The right foot pain was maintained with NRS 4 for 8 years, and the stimulation stopped 1 year back. SCS infection was diagnosed. INTERVENTIONS: The patient underwent SCS removal surgery. OUTCOMES: All SCS devices were removed successfully. The patient was discharged without any complications. CONCLUSIONS: While uncommon, infection after SCS implantation can occur even 9 years later. Immediate diagnosis, proper antibiotics, and surgical removal could be needed to prevent further spread of infection and better prognosis.

[Clinical observation on wrist-ankle acupuncture for shoulder-hand syndrome phaseâ after stroke].

OBJECTIVE: To compare the clinical efficacy between wrist-ankle acupuncture and conventional acupuncture on shoulder-hand syndrome (SHS) phaseⅠafter stroke. METHODS: A total of 64 patients with SHS phaseⅠafter stroke were randomized into a wrist-ankle acupuncture group and a conventional acupuncture group, 32 cases in each group. On the basis treatment of internal medicine and conventional rehabilitation, wrist-ankle acupuncture was applied at upper 4 area, upper 5 area and upper 6 area on the affected side in the wrist-ankle acupuncture group, while acupuncture was applied at Jianyu (LI 15), Quchi (LI 11), Shousanli (LI 10), etc. on the affected side in the conventional acupuncture group. The treatment was given 30 min each time, once a day, 5 days a week for 3 weeks in both groups. Before and after treatment, the visual analogue scale (VAS) score, degree of hand swelling, shoulder-hand syndrome scale (SHSS) score, Fugl-Meyer assessment for upper extremity (FMA-UE) score and modified Barthel index (MBI) score were observed, and the clinical therapeutic effect was evaluated in both groups. RESULTS: After treatment, the VAS scores, degree of hand swelling and SHSS scores were decreased (P<0.05), and the FMA-UE scores and MBI scores were increased (P<0.05) compared before treatment in both groups; in the wrist-ankle acupuncture group, the VAS score, degree of hand swelling and SHSS score were lower (P<0.05), and the FMA-UE score and MBI score were higher (P<0.05) than those in the conventional acupuncture group. The total effective rate was 96.9% (31/32) in the wrist-ankle acupuncture group, which was superior to 90.6% (29/32) in the conventional acupuncture group (P<0.05). CONCLUSION: Wrist-ankle acupuncture can effectively relieve pain and hand swelling, improve motor function of upper extremity and self-care ability of daily life in patients with shoulder-hand syndrome phaseⅠafter stroke, the therapeutic effect is superior to conventional acupuncture.

Two years follow-up of continuous erector spinae plane block in a patient with upper extremity complex regional pain syndrome type I.

BACKGROUND: Recalcitrant complex regional pain syndrome (CRPS) type 1 is a devastating condition. CASE PRESENTATION: We report a case of a patient in their twenties with left hand and forearm CRPS type I, transiently responsive to spinal cord stimulation, thoracic sympathectomy, and multimodal analgesia. The investigators initiated a trial of a single-shot erector spinae plane block at the T2 level, resulting in a clinically significant improvement in pain, function, vasomotor and sudomotor symptoms transiently for a 36-hour interval. As a result, a permanent e-port catheter implantation under combined ultrasound and fluoroscopic guidance was trialed. Two-year follow-up of the continuous erector spinae plane block (CESPB) indicated an 80% reduction in pain scores from baseline, and a 50% reduction in opiate consumption, with a clinically significant reduction in swelling, color changes, allodynia, and temperature asymmetry. CONCLUSION: Recalcitrant CRPS type 1 is a challenging life-altering condition that results in a cyclical triad of chronic pain, disability, and impaired psychosocial health. The profound and prolonged analgesic response to CESPB, highlights the clinical utility of this technique, and warrants more clinical investigation.

[Post-stroke shoulder-hand syndrome of phlegm-stasis obstruction treated with the combined therapy of eye acupuncture, Tengliao and rehabilitation training: a multi-central randomized controlled trial].

OBJECTIVE: To assess the efficacy on relieving pain and improving the range of motion of shoulder joint in post-stroke shoulder-hand syndrome of phlegm-stasis obstruction in treatment of the combined therapy of eye acupuncture, Tengliao (Chinese herbal warm dressing technique) and rehabilitation training (eye acupuncture + Tengliao + rehabilitation) as compared with the combined treatment of Tengliao and rehabilitation training (Tengliao + rehabilitation) and the simple rehabilitation training (rehabilitation). METHODS: A total of 356 patients with post-stroke shoulder-hand syndrome of phlegm-stasis obstruction were randomized into an eye acupuncture + Tengliao + rehabilitation group (group A, 122 cases, 2 cases dropped off), a Tengliao + rehabilitation group (group B, 120 cases, 3 cases dropped off) and a rehabilitation group (group C, 114 cases, 1 case dropped off). In the group C, the basic treatment was combined with routine rehabilitation training. In the group B, on the base of the treatment as the group C, Tengliao was exerted. A medical bag composed of over 20 Chinese herbal materials was heated and dressed at the affected area, 30 min each time, 5 times weekly. In the group A, besides the treatment as the group B, eye acupuncture was applied to heart region, kidney region, upper jiao region and lower jiao region, 30 min each time, 5 times weekly. The treatment lasted 28 days in all of three groups. Separately, before treatment, in 7, 14, 21 and 28 days of treatment, as well as in 14 days after treatment of follow-up, the score of visual analogue scale (VAS) for pain, the score of guides to evaluation of permanent impairment (GEPI) and the score of National Institutes of Health stroke scale (NIHSS) were observed in each group. RESULTS: The scores of VAS, GEPI and NIHSS were all improved with the treatment lasting in the three groups (P<0.000 1). In 7, 14, 21 and 28 days of treatment and in follow-up as well, VAS scores in the group A were all lower than the group C (P<0.05). After 14 days of treatment, GEPI score showed increasing trend, while NIHSS score showed decreasing trend in the group A compared with the group B. Before treatment, GEPI score was lower and NIHSS score was higher in the group A compared with the group C (P<0.05). It was suggested that the illness was slightly serious in the group A. After propensity score matching, in 14, 21 and 28 days as well as in follow-up, GEPI scores in the group A were higher than the group C respectively (P<0.05). Regarding NIHSS score at each time point, the difference had no statistical significance between the group A and the group C (P>0.05). CONCLUSION: The combined therapy of eye acupuncture, Tengliao and rehabilitation training obtains a better efficacy on post-stroke shoulder-hand syndrome of phlegm-stasis obstruction as compared with rehabilitation training.

[WANG Ju-yi's meridian diagnosis method combined with Bobath rehabilitation training for post-stroke shoulder-hand syndrome typeâ ].

OBJECTIVE: To compare the clinical efficacy differences between WANG Ju-yi 's meridian diagnosis method combined with Bobath rehabilitation training and Bobath rehabilitation training alone for post-stroke shoulder-hand syndrome (SHS) typeⅠ. METHODS: A total of 106 patients with post-stroke SHS typeⅠwere randomly divided into an observation group (53 cases, 2 cases dropped off ) and a control group (53 cases, 3 cases dropped off ). The patients in the both groups were treated with medications for basic diseases and conventional acupuncture at Waiguan (TE 5), Shousanli (LI 10) and Jianyu (LI 15) on the affected side. In addition, the patients in the control group were treated with Bobath rehabilitation training, 20 minutes each time; on the basis of the control group, the patients in the observation group were treated with WANG Ju-yi's meridian diagnosis method to adjust the abnormal parts in meridians of the hand taiyin and hand yangming on the affected side, 20 minutes each time. Both groups were treated once a day, 5 times a week for 8 weeks. The scores of visual analogue scale (VAS), upper-limb Fugl-Meyer assessment (FMA) and Barthel index (BI) were recorded before and after treatment as well as 6 weeks after treatment (follow-up), and the clinical efficacy of the two groups was evaluated after treatment. RESULTS: Compared before treatment, the VAS scores were reduced and the scores of upper-limb FMA and BI were increased in the two groups after treatment and in the follow-up (P<0.05). The VAS score in the observation group was lower than that in the control group (P<0.05), and the scores of upper-limb FMA and BI in the observation group were higher than those of the control group (P<0.05). The total effective rate in the observation group was 82.4% (42/51), which was higher than 62.0% (31/50) in the control group (P<0.05). CONCLUSION: WANG Ju-yi 's meridian diagnosis method combined with Bobath rehabilitation training could effectively treat post-stroke SHS typeⅠ, reduce pain symptoms and improve joint motor dysfunction, and improve the quality of life. Its curative effect is better than Bobath rehabilitation training alone.

Functional Outcomes After a Physiotherapy Program in Elderly Patients With Complex Regional Pain Syndrome Type I After Distal Radius Fracture: A Prospective Observational Study.

BACKGROUND: No published prospective studies have reported the clinical effects of physiotherapy at 1-year follow-up in patients with complex regional pain syndrome type I (CRPS I) after distal radius fracture (DRF). The purpose of this study was to evaluate at 1-year follow-up the functional effects of physiotherapy program in elderly patients with CRPS I after extra-articular DRF. METHODS: A total of 72 patients with CRPS I after DRF were prospectively recruited. All patients were treated with a 6-week supervised physiotherapy treatment. Three evaluations were performed: at the beginning, at the end of the treatment, and at 1-year follow-up. Wrist function, upper limb function, grip strength, and pain intensity were assessed with the Patient-Rated Wrist Evaluation (PRWE), Disabilities of the Arm, Shoulder, and Hand (DASH), Jamar dynamometer, and Visual Analogue Scale (VAS), respectively. RESULTS: At 1-year follow-up, the PRWE showed a decrease of 21.6 points (Cohen's d = 2.8; 95% confidence interval [CI] = 18.6-24.6; P < .05); the DASH showed a decrease of 23.8 points (Cohen's d = 2.9; 95% CI = 20.8-26.7; P < .05); grip strength showed an increase of 40.6% (Cohen's d = 5.0; 95% CI = 43.5-37.6; P < .05); and the VAS showed a decrease of 2.6 cm (Cohen's d = 1.9; 95% CI = 2.11-3.16; P < .05). CONCLUSION: At 1-year follow-up, a physiotherapy program showed clinically and statistically significant results in all functional outcomes in elderly patients with CRPS I after extra-articular DRF.

Treatment of Distal Radius Fracture: Does Early Activity Postinjury Lead to a Lower Incidence of Complex Regional Pain Syndrome?

Background: The optimal treatment for a distal radius fracture (DRF) remains an ongoing discussion. This study observed whether early activity postinjury can lead to the prevention of type 1 complex regional pain syndrome (CRPS-1). Method: Patients who underwent nonoperative treatment for a DRF were invited to participate in this study. Patients followed an exercise program with progressive loading exercises at home immediately after cast removal. After a minimum of 3 months, patients were interviewed by telephone to determine the presence of disproportionate pain. If present, the patients were seen during a clinical consultation to determine whether they had CRPS-1, using the Budapest Diagnostic Criteria. Results: Of the 129 patients included in this study, 12 reported disproportionate pain, and none were diagnosed with CRPS-1. The incidence of CRPS-1 was zero in this study. Conclusion: A more active treatment approach seems to lower the incidence of CRPS-1. A larger randomized study is necessary to strengthen the evidence.

Hyperbaric oxygen treatment in recurrent development of complex regional pain syndrome: A case report.

A broad spectrum of conditions including neuropathic pain, complex regional pain syndrome (CRPS) and fibromyalgia, have been implicated as causes of chronic pain. There is a need for new and effective treatments that patients can tolerate without significant adverse effects. One potential intervention is hyperbaric oxygen treatment (HBOT). The case reported here is unique in describing repeated HBOT in a patient who developed recurrent post-traumatic CRPS of the lower as well as the upper limbs. In the first event, two months after distortion and abruption of the external right ankle, the patient suffered leg pain, oedema formation, mild hyperaemia, limited mobility of the ankle and CRPS Type 1. In the second event, the same patient suffered fracture-dislocation of the distal radius 1.5 years after the first injury. After the plaster cast was removed the patient developed pain, warmth, colour changes, oedema formation and limited wrist mobility with CRPS Type 1. Pharmacological treatment as well as HBOT were used with significant improvement of functional outcome in both cases. Some studies suggest that patients with a history of CRPS are more likely to develop secondary CRPS compared to the rates reported in the literature among the general population. Patients with a history of CRPS should be counselled that they may be at risk for developing secondary CRPS if they undergo surgery or sustain trauma to another extremity.

Socioeconomic Disparities in the Utilization of Spinal Cord Stimulation Therapy in Patients with Chronic Pain.

OBJECTIVES: Spinal cord stimulation (SCS) therapies are used in the management of patients with complex regional pain syndrome I (CRPS I) and failed back surgery syndrome (FBSS). The purpose of this study was to investigate the racial and health insurance inequalities with SCS therapy in patients with chronic pain who had CRPS I and FBSS. METHODS: Patients with chronic pain who had a discharge diagnosis of FBSS and CRPS I were identified using the National Inpatient Sample database. Our primary outcome was defined as the history of SCS utilization by race/ethnicity, income quartile, and insurance status. Multivariable logistic regression was used to determine the variables associated with utilization of SCS therapy. RESULTS: Between 2011 and 2015, 40,858 patients who were hospitalized with a primary diagnosis of FBSS and/or CRPS I were identified. Of these patients, 1,082 (2.7%) had a history of SCS therapy. Multivariable regression analysis revealed that compared to White patients, Black and Hispanic patients had higher odds of having SCS therapy (Black patients: odds ratio [OR] = 1.41; 95% confidence interval [CI], 1.12 to 1.77; P = 0.003; Hispanic patients: OR = 1.41; 95% CI, 1.10 to 1.81; P = 0.007). Patients with private insurance had significantly higher odds of having SCS therapy compared with those with Medicare (OR = 1.24; 95% CI, 1.08 to 1.43; P = 0.003). Compared to patients with Medicare, Medicaid patients had lower odds of having SCS therapy (OR = 0.50; 95% CI, 0.36 to 0.70; P < 0.001). CONCLUSIONS: Our study suggests that socioeconomic disparities may exist in the utilization of SCS among hospitalized patients with CRPS I and FBSS the United States. However, confirming these data from other administrative databases, in the outpatient setting, may shed more insight.

Utilization of Concurrent Dorsal Root Ganglion Stimulation and Dorsal Column Spinal Cord Stimulation in Complex Regional Pain Syndrome.

INTRODUCTION: Complex regional pain syndrome (CRPS) can be effectively treated with spinal cord stimulation (t-SCS). There is also evidence that dorsal root ganglion (DRG) stimulation may be superior to t-SCS in CRPS. However, there has been no published data, to our knowledge, that looked at the concurrent use of t-SCS and DRG stimulation for treatment of CRPS. METHODS: Our study includes four patients with severe CRPS who had all been implanted with a t-SCS. While all these patients had positive results from their t-SCS, they all had areas which lacked coverage, giving them incomplete pain relief. These patients also underwent successful trial and implantation of DRG-S. All four patients reported further improvement in their residual pain and function with DRG-S (>60%), and even superior pain relief (>80%) with concurrent use of t-SCS and t-SCS. RESULTS: All patients had a diagnosis of lower extremity CRPS-1. After DRG-S implantation, multiple attempts were made in each patient to use DRG-S alone by temporarily turning the t-SCS off. However, in each attempt, all patients consistently reported superior pain relief and improvement in function with the concurrent use of t-SCS and DRG, as compared to DRG alone. The average numeric rating scale pain score decreased from approximately 7 in the regions not covered by t-SCS to 3 after DRG-S implantation, and to 1.25 with concurrent use t-SCS and DRG-S. CONCLUSION: Both t-SCS and DRG-S have been shown to be effective in treatment of patients with CRPS. In our study, concurrent use of t-SCS and DRG-S provided significant improvement in pain and function as compared to using either device alone. This suggests the potential that combination therapy with t-SCS and DRG-S may be beneficial in patients with CRPS. Further prospective studies are required to evaluate this concept.

Direct Peripheral Nerve Stimulation for the Treatment of Complex Regional Pain Syndrome: A 30-Year Review.

INTRODUCTION: Complex regional pain syndrome (CRPS), formerly known as reflex sympathetic dystrophy (RSD), is a difficult to treat condition characterized by debilitating pain and limitations in functional ability. Neuromodulation, in the form of spinal cord stimulation (SCS) and peripheral nerve stimulation (PNS), have been traditionally used as a treatment for CRPS with variable success. OBJECTIVE: This chart review describes the use of implantable PNS systems in the treatment of CRPS of the upper and lower extremities spanning nearly three decades. MATERIALS AND METHODS: A retrospective chart review was performed on 240 patients with PNS implanted between 1990 and 2017 at our institution. Of these, 165 patients were identified who had PNS systems implanted for a diagnosis of CRPS. Patient profile, including baseline characteristics, comorbidities, past/current interventions/medications and targeted nerves, was descriptively summarized through standard summary statistics. Patients' pain scores and opioid consumptions at baseline (preimplant), 1 month, 6 months, and 12 months were collected and compared. Device revisions and explants were summarized, and patient functional outcomes were described. RESULTS: Pain scores at baseline and at 12-month follow-up were decreased from a mean of 7.4 ± 1.6 to 5.5 ± 2.4 and estimated to be 1.87 (95% CI: [1.29, 2.46], paired t-test p-value <0.001) lower at 12 months. At baseline, 62% of patients were on chronic opioid therapy, compared with 41% at 12 months. Of 126 patients who reported changes in functional status, 64 (51%) reported improvement, 27 (21%) reported worsening, and 35 (28%) did not report any meaningful change. Excluding end-of-life battery replacements, surgical revision occurred in 56 (34%) of patients. Thirteen patients (8%) underwent implantation of a second PNS because of symptomatic expansion outside of the original painful region. Device explant was performed in 32 (19%) of patients. Median length of follow-up was 74 [14, 147] months. Of the 36 patients who continue to follow-up at our institution, 29 (81%) continue to use their PNS. CONCLUSIONS: We can conclude that PNS is a useful modality to improve function and reduce long-term pain in selected patients suffering from CRPS type I and type II.

[Analysis of the clinical effect on post-stroke shoulder hand syndrome stage â treated with the along-meridian trochar acupuncture therapy].

OBJECTIVE: To compare the differences in the clinical effect on post-stroke shoulder hand syndrome (SHS) stage Ⅰ between the along-meridian trochar acupuncture therapy and the routine acupuncture therapy with filiform needles. METHODS: A total of 80 patients with post-stroke SHS stage I were divided into a treatment group (41 cases) and a control group (39 cases) according to the random number table. In the control group, the common filiform needles were used to stimulate Jianyu (LI15), Jianliao (TE14), Jianzhen (SI9), Jianzhongshu (SI15), Jianwaishu (SI14), 5 times a week, 3 weeks as 1 course. In the treatment group, along-meridian trochar acupuncture therapy was applied, 3 times a week, 3 weeks as 1 course. The patients in both groups were all treated with basic medications and routine rehabilitation training. Pain degree, edema degree, upper limb motor function and activity of daily living were observed in the two groups before the treatment, at the end of the treatment and in follow-up. At the end of treatment and in follow-up, the therapeutic effect was evaluated respectively in the patients of the two groups. RESULTS: Compared with the values before treatment, the VAS score of the upper limb was reduced obviously (P< 0.001), the score of the upper limb motor function and Barthel index were increased obviously (P<0.001, P<0.05) in the patients of the two groups, the score of edema degree of the affected limb was reduced after treatment in the patients of the treatment group (P<0.001). Compared with the control group, VAS score of the upper limb and the score of edema degree of the affected limb were obviously lower (P<0.001), and the score of the upper limb motor function and Barthel index were obviously higher in the treatment group (P<0.001). The total effective rate was 66.7% (26/39) after treatment and was 74.4% (29/39) in follow-up in the treatment group and they were 20.5% (8/39) and 28.2% (11/39) respectively in the control group. The total effective rates after treatment and in follow-up in the treatment group were all obviously higher than those in the control group respectively (P<0.001). CONCLUSION: The along-meridian trochar acupuncture therapy remarkably relieves pain and edema and improves the upper limb motor function and the activity of daily living in the patients with post-stroke shoulder hand syndrome and its clinical therapeutic effect is definite.
