RESUMEN
BACKGROUND/AIM: Task-specific repetitive training, a usual care in occupational therapy practice, and robotic-aided rehabilitation with bilateral practice are used to improve upper limb motor and task performance. The difference in effects of two strategies requires exploration. This study compared the impact of robotic-assisted therapy with bilateral practice (RTBP) and usual task-specific training facilitated by therapists on task and motor performance for stroke survivors. METHODS: Forty-three community-dwelling stroke survivors (20 males; 23 females; 53.3 ± 13.1 years; post-stroke duration 14.2 ± 10.9 months) were randomised into RTBP and usual care. All participants received a 10-minute per-protocol sensorimotor stimulation session prior to interventions as part of usual care. Primary outcome was different in the amount of use (AOU) and quality of movement (QOM) on the Motor Activity Log (MAL) scale at endpoint. Secondary outcomes were AOU and QOM scores at follow-up, and pre-post and follow-up score differences on the Fugl-Meyer Assessment (FMA) and surface electromyography (sEMG). Friedman and Mann-Whitney U tests were used to calculate difference. RESULTS: There were no baseline differences between groups. Both conditions demonstrated significant within-group improvements in AOU-MAL and FMA scores following treatment (P < 0.05) and improvements in FMA scores at follow-up (P < 0.05). The training-induced improvement in AOU (30.0%) following treatment was greater than the minimal detectable change (16.8%) in the RTBP group. RTBP demonstrated better outcomes in FMA wrist score (P = 0.003) and sEMG of wrist extensor (P = 0.043) following treatment and in AOU (P < 0.001), FMA total score (P = 0.006), FMA wrist score (P < 0.001) and sEMG of wrist extensor (P = 0.017) at follow-up compared to the control group. Control group boost more beneficial effects on FMA hand score (P = 0.049) following treatment. CONCLUSIONS: RTBP demonstrated superior upper limb motor and task performance outcomes compared to therapists-facilitated task training when both were preceded by a 10-minute sensorimotor stimulation session.

AIMS/INTRODUCTION: The purpose of the present study was to identify whether there are differences in hand dexterity, hand functional performance and quality of life between diabetes patients with mononeuropathy and polyneuropathy of their hands to further present the importance regarding the impacts of diabetic neuropathic deficits on patients' functional capacity. MATERIALS AND METHODS: The neurological deficits of 127 patients with type 2 diabetes were examined by electrophysiological tests for the median and ulnar nerves, and were stratified into the diabetic mononeuropathy, diabetic polyneuropathy and non-diabetic neuropathy groups by sensory amplitude of these nerves. The Purdue pegboard test, Michigan Hand Outcomes Questionnaire, and Diabetes-39 were carried out to understand patients' hand dexterity, functional hand performance and quality of life, respectively. RESULTS: The results showed significant differences in all subtests of the Purdue pegboard test among the three groups. Furthermore, aesthetics, patient's satisfaction of the Michigan Hand Outcomes Questionnaire and diabetes control, sexual functioning, energy, and mobility of the Diabetes-39 also showed significant differences among the three groups. CONCLUSIONS: The present study shows the patients with polyneuropathy suffer from more negative impacts on hand functional performance and quality of life than those with mononeuropathy and without neuropathy. These findings might assist both patients and clinicians in better realizing the impacts of neuropathic hands, and planning suitable strategies of intervention or health education to prevent declines in hand functions.

STUDY DESIGN: Case-controlled cohort study. INTRODUCTION: Sensory function is difficult to observe during nerve regeneration processes. Traditional sensory tests are limited to identifying the level of functioning hand sensation for sensory stimulus is given passively to the cutaneous surface of the hand. PURPOSE OF THE STUDY: To examine the outcome changes in the manual tactile test (MTT), Semmes-Weinstein monofilament (SWM) and 2-point discrimination (2PD) tests for patients with nerve repair and to investigate the concurrent validity of MTT by comparing it with the results of traditional tests. METHODS: Fifteen patients with nerve injury of the upper limbs were recruited, along with 15 matched healthy controls. The MTT, SWM, and 2PD tests were used to examine the sensory status of the subjects. RESULTS: Three subtests (barognosis, roughness differentiation, and stereognosis) in MTT showed that the patients improved with time. A moderate and mild correlation was found between the MTT and 2PD results and between the barognosis and SWM results. CONCLUSIONS: The MTT provides practical and functional perspectives on detecting nerve progression during the courses of degeneration and regeneration. LEVEL OF EVIDENCE: IV.

Purpose This study investigates the effects of kinematic disturbances in rheumatoid thumb on patient's hand functions via objective and patient-perceived measurements. Method Twenty-one patients with rheumatoid arthritis (RA) and 21 healthy age- and gender-matched individuals were recruited to receive the objective evaluations, including the Purdue Pegboard Test, Jamar dynamometer, pinch-meter, Permanent Impairment Scale and self-administrated measurements, including the Health Assessment Questionnaire (HAQ) and Manual Ability Measure-36 (MAM-36). An electromagnetic tracking system was used to measure thumb kinematics. The differences in the measures between the RA and control groups and the dominant and non-dominant hands of the RA group were examined. The relationships between the thumb kinematics and hand functional capabilities, as well as impairment levels, were also explored. Results The RA group showed significantly smaller thumb movement capabilities and hand strength, as well as worse scores in hand dexterity, MAM-36 and HAQ than healthy controls. The movement workspace of the RA thumb showed moderate correlations with the factors of hand strength, dexterity, impairment scale, MAM-36 and HAQ scores. Conclusions The findings indicate deficits related to the movement capability of the RA thumb may negatively influence hand dexterity and functional hand performance, as well as life quality, for the patients with RA. Implications for Rehabilitation A deformed rheumatoid thumb might limit the movement workspace of the thumb and consequently impair the hand performance as well as the life quality. The dominant thumb of the RA patients might have greater structural and functional deterioration than the non-dominant side. Suitable joint protection strategies, exercises and orthotics should be early applied to the RA patients for preserving hand functions.

Health care professionals are known to have a high risk for work-related musculoskeletal disorders. However, the information on the risk of new-onset spine-related musculoskeletal disorders (SRMDs) in health care professionals is insufficient. This study aimed to investigate new-onset spine disorder associations among physical, occupational, and pharmacy health care professionals working in different workplaces.Taiwan's National Health Insurance Research Database for registered medical personnel claims from 2000 to 2011 was analyzed. An age- and sex-matched longitudinal cohort study of 7448 subjects (1682 physiotherapists, 1682 occupational therapists [OTs], and 3724 pharmacists) with or without new-onset spine disorders was conducted. The hazard ratios for the development of new-onset spine disorders were estimated among these 3 groups.The overall percentage of new-onset SRMD for physiotherapists is 32.12. The median time from obtaining a registered license to developing SRMD is 1.94 years. The log-rank test showed that physiotherapists have the least possibility of having a SRMD-free rate (Pâ<â0.0001). The Cox model showed that physiotherapists have a higher risk of new-onset SRMD (hazard ratio: 1.65, 95% confidence interval: 1.48-1.84, Pâ<â0.0001) compared with OTs and pharmacists. Physiotherapists working in clinics have a 2.40-fold increased risk of developing SRMD (95% confidence interval: 1.97-2.92, Pâ<â0.0001) relative to OTs and pharmacists.This may be the first study regarding new-onset SRMD in physiotherapists based on a powerful nationwide population-based database. We conclude that working in clinics is a potential risk for new-onset SRMD in physiotherapists. Therefore, we suggest that physiotherapists should pay more attention to this issue to prevent the development of spine disorders.

OBJECTIVES: To comprehend the merits of a Manual Tactile Test (MTT) in assessing hand sensorimotor functions by exploring the relations among 3 subtests along with the precision pinch performances for patients with peripheral nerve injuries (PNIs); and to understand the accuracy of the MTT by constructing the sensitivity and specificity of the test for patients with PNI. DESIGN: Case-control study. SETTING: Hospital and local community. PARTICIPANTS: Patients with PNI (n=28) were recruited along with age-, sex-, and handedness-matched healthy controls (n=28) (N=56). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The Semmes-Weinstein monofilament, moving and static 2-point discrimination, roughness differentiation, stereognosis and barognosis subtests of the MTT, and precision pinch performance were used to examine the sensory and sensorimotor status of the hand. RESULTS: The worst results in all sensibility tests were found for the patients with PNI (P<.001) in comparison with the controls. Multiple linear regression analysis showed the MTT was a better indicator for predicting the sensorimotor capacity of hands in the patients with PNI (r(2)=.189, P=.003) than the traditional test (r(2)=.088, P=.051). The results of the receiver operating characteristic curve estimation show that the area under the curve was .968 and .959 for the roughness differentiation and stereognosis subtests, respectively, and .853 for the barognosis subtest, therefore revealing the accuracy of the MTT in assessing sensorimotor status for patients with PNI. CONCLUSIONS: This study indicates that the MTT is highly accurate and a significant predictor of sensorimotor performance in hands of patients with PNI. The MTT could therefore help clinicians obtain a better understanding of the sensorimotor and functional status of the hand with nerve injuries.

Glomus tumors are rare, usually benign, vascular hamartomas consisting cells resembling the smooth muscle cells of the normal glomus body. They can be solitary or multiple, whereas solitary tumors are majorly located on the digits. Digital glomus tumors most commonly appear in subungual region and show a strong female predominance. There are several classical symptoms, clinical tests, and imaging tools, such as X-ray, magnetic resonance imaging, and ultrasonography, which can provide good accuracy for clinical diagnosis. However, misdiagnosis and delayed diagnosis are still commonly observed because primary physicians are unfamiliar with classical symptoms and clinical tests. Complete surgical excision often can result in complete relief of symptoms. Recurrence is largely caused by incomplete excision, but repeated image study is recommended to rule out new or malignant lesions. This series is a retrospective review of 50 cases with glomus tumors managed at our institute. We aim to review the key aspects of glomus tumor and provide a simple guideline for earlier diagnosis and treatment.

Traumatic injuries to the digits resulting in soft tissue or bone loss require reconstruction. Traditionally, local flaps, such as homodigital flaps, heterodigital flaps, pedicled flaps, or distant flaps, are used for digital resurfacing. However, free tissue transfers can be used in selected patients. In this study, we present the use of different free flaps including groin skin flaps, groin osteocutaneous flaps, groin chimeric flaps, second dorsal metacarpal artery flaps, and partial toe flaps for digital reconstruction. A total of 19 digits were treated with 16 free flaps in our hospital. Of the flaps used, 5 were free groin skin flaps, 4 were free partial toe flaps, 3 were free groin chimeric flaps, 2 were free groin osteocutaneous flaps, and 2 were free second dorsal metacarpal artery flaps. The average flap size was 4.7 × 2.0 cm (range, 1.5 × 1 to 5 × 4 cm), and the average operative time was 6.0 hours (range, 4-9 hours). All flaps survived without partial or total necrosis. In conclusion, the free flap is a reliable and safe alternative for digital reconstruction. Moreover, the free groin flap provides not only a chimeric pattern for multiple fingers coverage but also an osteocutaneous pattern for thumb lengthening. The free second dorsal metacarpal artery flap provides a tenocutaneous pattern for tendon reconstruction and soft tissue coverage simultaneously, and the free partial toe flap is an excellent alternative for pulp reconstruction in terms of aesthetic appearance and functional outcome.

To investigate whether sensorimotor control of the hand could be an outcome indicator after carpal tunnel release (CTR), this work examined changes in the results of patients' manual tactile test (MTT), pinch-holding-up activity (PHUA), two-point discrimination (2PD) and Semmes-Weinstein monofilament (SWM) tests. Participants included 30 predominantly sensory neuropathy CTS patients, as confirmed by a nerve conduction study. The MTT, precision pinch performance in PHUA and traditional sensibility (2PD and SWM) tests were used to examine different aspects of sensory status at the time-points of two weeks before operation and one month post-operation, with a single-blind design. The results showed significant improvements in the sensory function as detected by the 2PD and SWM tests (p<0.001) and sensorimotor function as detected by the MTT (p<0.001) and PHUA test (p<0.05) for patients receiving CTR. The responsiveness of the SWM, MTT and PHUA tests (effect size>0.5, p<0.01) are better than that of two-point discrimination test (effect size<0.5, p<0.001). However, pinch strength saw a decline compared to baseline with a moderate effect sizes (effect size = 0.7, p<0.001). This cohort study found that the MTT and PHUA test can both meet all the statistical criteria with regard to assessing treatment outcomes for patients with CTS. In addition, the results of this work provide clinicians with the information that the sensorimotor functions of the hands, as assessed by MTT and PHUA, are responsive to clinical changes due to CTR.

BACKGROUND: To understand the impacts of disease chronicity and hyperglycaemia on sensorimotor control of hands of diabetic patients, this study investigated the differences in hand sensation, strength and motor control by applying the pinch-holding-up activity test for patients with diabetes mellitus (DM) with different levels of glycaemic control and disease chronicity. METHODS: One hundred and fifty-nine patients with clinically defined DM were included. Semmes-Weinstein monofilament, static two-point discrimination and moving two-point discrimination, maximal pinch strength precision pinch performance tests and nerve conduction studies (NCS) of the subjects were carried out. Forty-seven (29.6%) patients were in the HbA(1c) < 7% category, and 112 (70.4%) patients were in the >7% group. There were 87 (54.7%) patients with the disease duration <10 years, and 72 (45.3%) patients with disease duration â§10 years. RESULTS: The severity of hyperglycaemia significantly impacts the results for Semmes-Weinstein monofilament, precision pinch force control, sensory and motor NCS tests (p < 0.05). In addition, the chronicity of disease influences the motor control of precision pinch performance and the amplitude of motor NCS (p < 0.05) for the diabetes patients. CONCLUSIONS: The evidence suggests that disease chronicity and hyperglycaemia have impacts on sensorimotor control in the hands of DM patients. In addition, the efficiency of prehensile forces of hand-to-object interactions in the pinch-holding-up activity test could be significant for identifying hand function, as well as pathologic changes in median nerve function, for patients with DM.

PURPOSE: To comprehend the associations among the dexterity and functional performance of the hands and quality of life in diabetic patients with neuropathic hands, via objective- and patient-perceived measurements. METHODS: The study participants were 144 diabetes patients who received objective evaluations, including the Purdue pegboard test, electrophysiological testing in sensory amplitude of the median nerve, and self-administrated measurements, including the Michigan Hand Outcomes Questionnaire (MHQ) and Diabetes-39 (D-39). Pearson's and Spearman's correlation tests were conducted to assess the relationships among hand neuropathy, hand dexterity and functions, and quality of life. RESULTS: The results show that the amplitude of the sensory nerve action potential of the median nerve was positively correlated with hand dexterity (r = 0.28-0.43; p < 0.01) and the total score of MHQ (r = 0.24-0.33; p < 0.01). Objective hand dexterity had mild to moderate relationships with most of the MHQ results, but only weak associations with some dimensions of the D-39 results. The MHQ results were negatively correlated with the D-39 scores, with mild to moderate relationships in the domains of energy/mobility and anxiety. CONCLUSIONS: In comparison with diabetic feet, neuropathic diabetic hands are an easily neglected problem, with insufficient empirical evidence in the literature to indicate its impact on functional performance and quality of life. This study showed that lesions related to neural functioning in the diabetic hand may negatively influence dexterity and functional hand performance and thus also affect the quality of life.

To comprehend the sensorimotor control ability in diabetic hands, this study investigated the sensation, motor function and precision pinch performances derived from a pinch-holding-up activity (PHUA) test of the hands of diabetic patients and healthy subjects. The precision, sensitivity and specificity of the PHUA test in the measurements of diabetic patients were also analyzed. We hypothesized that the diabetic hands would have impacts on the sensorimotor functions of the hand performances under functionally quantitative measurements. One hundred and fifty-nine patients with clinically defined diabetes mellitus (DM) and 95 age- and gender-matched healthy controls were included. Semmes-Weinstein monofilament (SWM), static and moving two-point discrimination (S2PD and M2PD), maximal pinch strength and precision pinch performance tests were conducted to evaluate the sensation, motor and sensorimotor status of the recruited hands. The results showed that there were significant differences (all p<0.05) in SWM, S2PD, M2PD and maximum pinch strength between the DM and control groups. A higher force ratio in the DM patients than in the controls (p<0.001) revealed a poor ability of pinch force adjustment in the DM patients. The percentage of maximal pinch strength was also significantly different (p<0.001) between the DM and control groups. The sensitivity, specificity and area under the receiver operating characteristic curve were 0.85, 0.51, and 0.724, respectively, for the PHUA test. Statistically significant degradations in sensory and motor functions and sensorimotor control ability were observed in the hands of the diabetic patients. The PHUA test could be feasibly used as a clinical tool to determine the sensorimotor function of the hands of diabetic patients from a functional perspective.

In Taiwan, the aquatic environment and endemic hepatitis contribute to the high susceptibility of Vibrio vulnificus infection. A multidisciplinary treatment protocol for necrotizing fasciitis caused by V. vulnificus was developed in our institute, namely, ceftriaxone or ceftazidime combined with doxycycline or minocycline followed by an emergency fasciotomy and intensive care unit admission. We retrospectively reviewed 100 cases to evaluate the effectiveness of our treatment protocol and identify independent predictors of mortality to improve clinical outcomes. Cases of culture-confirmed V. vulnificus infection between January 1996 and December 2011 were reviewed. Necrotizing fasciitis was surgically diagnosed if these criteria were met: necrotic fascia, "dishwater discharge", and loss of resistance while doing finger dissection along the fascia plane. One hundred cases met these criteria and were included for analysis. Eighteen patients died (18 % mortality). Unknown injury events, presence of multiple skin lesions, leukocytes < 10,000 cells/mm(3), platelets < 100,000/mm(3), serum creatinine ≥1.3 mg/dL, serum albumin < 2.5 mg/dL, and delayed treatment beyond 3 days post-injury or symptom onset were associated with significantly higher mortality. Multivariate analysis showed that treatment delayed beyond 3 days is an independent factor indicating a poor prognosis (OR 10.75, 95 % CI 1.02-113.39, p = 0.048). Early diagnosis and prompt treatment within 3 days post-injury or symptom onset should be the goal for treating patients with necrotizing fasciitis caused by V. vulnificus. Additional investigations to rescue patients with a prolonged disease course of necrotizing fasciitis (≥3 days) may be important.

We presented a patient who experienced the anterolateral thigh (ALT) flap failure but the reconstruction was successfully salvaged by harvesting a second ALT flap from the same donor site 2 days after the first reconstruction. A 47-year-old man received cancer ablation for right mouth floor squamous cell carcinoma. The resultant defect was planned to be reconstructed with the ALT flap. During the flap dissection, we identified three proximal cutaneous perforators originating from the transverse branch of the lateral circumflex femoral artery (t-LCFA) and two distal cutaneous perforators originating from the descending branch (d-LCFA). We harvested a skin flap based on the distal two perforators and divided the d-LCFA just distal to the bifurcation of the d-LCFA and the t-LCFA. Unfortunately, the ALT flap showed venous congestion on postoperative day 2 and eventually failed. We harvested a second ALT flap from the same donor site based on the previously preserved perforators. The recovery course was smooth thereafter. We believe that the harvest of a second ALT flap from the same donor site may be an option, to avoid other donor site violation, in some patients who experienced the first flap loss. © 2014 Wiley Periodicals, Inc.

OBJECTIVES: To investigate how the severity levels revealed in a nerve conduction study (NCS) affect the results of the Manual Tactile Test (MTT) for patients with carpal tunnel syndrome (CTS), and to examine the relationships between the results of the MTT and precision pinch performance. DESIGN: Case-control studies. SETTING: Hospital and local community. PARTICIPANTS: Patients with CTS (N=70) with 119 affected hands were studied. A control group matched by age, sex, and hand dominance was also recruited. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: CTS severity was determined based on NCS findings. The MTT, traditional sensory tests, and precision pinch performance were used to examine the functional sensory status of the hand from different perspectives. RESULTS: The patients with CTS exhibited deterioration in all of the sensibility tests (P<.001). The results showed that the MTT could classify subgroups of severity in CTS (P<.001). A moderate correlation was found between the results of the MTT and precision pinch performance (r=.526-.585, P<.001). Multiple linear regression analysis showed that the MTT results were useful indicators for predicting precision pinch performance and differentiating severity in subjects with CTS (r(2)=.376 and .323, respectively). CONCLUSIONS: The findings indicate that the MTT could be a valid and useful assessment for hand sensibility and prehensile pinch performance in patients with CTS.

To understand the feasibility of a novel functional sensibility test for determining precision pinch performance in patients with carpal tunnel syndrome, this study investigates the validity, sensitivity and specificity of functional sensibility derived from a pinch-holding-up activity (PHUA) test. Participants include 70 clinically defined carpal tunnel syndrome (CTS) patients with 119 involved hands and 70 age- and gender-matched controls. To examine the discriminating ability of the functional sensibility test, the differences in the ability of pinch force adjustments to the inertial load of handling object between CTS and control subjects are analyzed. The results of functional sensibility are correlated with the severity of CTS to establish concurrent validity. The receiver operating characteristic (ROC) curve is constructed to demonstrate the accuracy of the proposed test. The functional sensibility score significantly discriminates the patients and control groups (respectively, 12.94±1.72 vs. 11.51±1.15N in peak pinch force (FPPeak), p<0.001; 2.92±0.41 vs. 2.52±0.24 in force ratio, p<0.001) and is moderately correlated (râ=â0.42-0.54, p<0.001) with the results of traditional sensibility tests (touch-pressure threshold and two-point discrimination test). In addition, there is a statistical difference in the results of functional sensibility (p<0.001) among the subgroups of CTS severity based on electrophysiological study. The sensitivity and specificity are 0.79 and 0.76, respectively, for the functional sensibility test. The areas under the ROC curve are 0.85 and 0.80 for the force ratio and FPPeak, respectively. In conclusion, the functional sensibility test could be feasibly used as a clinical tool for determining both the sensibility and precision pinch performance of hands for the patients with CTS.

BACKGROUND: Biofeedback training is widely used for rehabilitative intervention in patients with central or peripheral nervous impairment to train correct movement patterns; however, no biofeedback apparatus is currently available to correct pinch force ratios for patients with sensory deficiencies. DESIGN: A cross-sectional and longitudinal design was used in an observational measurement study for establishing a prototype and to determine the effects of biofeedback intervention, respectively. OBJECTIVE: This study aimed to develop a computerized evaluation and re-education biofeedback (CERB) prototype for application in clinical settings. METHODS: A CERB prototype was developed integrating pinch apparatus hardware, a biofeedback user-controlled interface, and a data processing/analysis interface to detect momentary pinch performances in 79 people with normal hand sensation. Nine patients with hand sensory impairments were recruited to investigate the effects of training hand function with the CERB prototype. RESULTS: Hand dominance, pinch pattern, and age significantly affected the peak pinch force and force ratio for lifting a 480-g object with a steel surface. In the case of the 79 volunteers with normal hand sensation, hand dominance affected the time lag between peak pinch force and maximum load; however, it was unaffected by pinch pattern or age. Training with the CERB prototype produced significant improvements in force ratio and better performance in the pin insertion subtests, although the results for both 2-point discriminative and Semmes-Weinstein monofilament tests did not change significantly. LIMITATIONS: The intervention findings are preliminary. CONCLUSIONS: This study developed a conjunct system suited for evaluating and restoring sensorimotor function for patients with impaired hand sensibility. The results from the participants with normal hand sensation could serve as a reference database for comparison with patients with nerve injuries.

OBJECTIVES: To (1) develop the Manual Tactile Test (MTT) for evaluating the hand perception to distinguish objects' characteristics; (2) establish the reliability and validity of the MTT for patients with carpal tunnel syndrome (CTS); and (3) integrate a normative database into the test. DESIGN: Cohort and case-control studies. SETTING: Hospital and local community. PARTICIPANTS: Participants included patients with CTS (n=70) and healthy volunteers (n=125). Twenty young volunteers were enrolled to evaluate the reliability of the test. Seventy patients with CTS and 70 age- and sex-matched controls were recruited to establish the discriminate validity and receiver operating characteristic (ROC) curves for the MTT. A normative database was constructed from 125 healthy, right-handed participants. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The MTT was designed to discriminate the characteristics of the objects' weight (barognosis test), texture (roughness differentiation test), and shape (stereognosis test) via active hand exploration. The times required discriminating the characteristics of objects and the accuracy of judgment were recorded and analyzed. RESULTS: High Cronbach alpha values (.83-.91) and small coefficient of variation (.10-.16) values showed that the MTT is a reliable testing tool. The results significantly discriminated the patients from the control group (P<.001). The sensitivity and specificity were .64 to .81 and .73 to .76, respectively, for the 3 subtests. The ROC curve area for the 3 subtests ranged from .70 to .84. The results of the MTT obtained from 125 healthy subjects showed that age significantly affects hand perceptive function (P<.001). CONCLUSIONS: The MTT is a reliable, accurate, and valid tool for determining the impairment of manual touch sensibility for CTS and can help clinicians understand age-related degradation in sensorimotor control of the hand in the elderly population.

Deep partial thickness burn (DPTB) wound fluids have a greater propensity for establishing neovascularization than did superficial partial thickness burn (SPTB) wound fluids in our previous study. To investigate the factors responsible for this activity, cytokine array and enzyme-linked immunosorbent assay were used to perform an expression analysis of angiogenic factors in burn fluid. Although present in approximately equal amounts in both SPTB and DPTB blister fluids from burn patients, angiogenin does appear to be involved in the ability of DPTB blister fluid to promote neovascularization in vitro and in vivo. Angiogenin alone was sufficient to induce endothelial differentiation of circulating angiogenic cells (CAC) without vascular endothelial growth factor A involvement. In addition, angiogenin was positively associated with CAC differentiation in the burn blister fluid. Blocking the effect of angiogenin in burn blister fluids resulted in a significant reduction of endothelial cell proliferation, CAC differentiation, and new blood vessels formation in vivo. Moreover, immunohistochemistry revealed that high angiogenin expression colocalizes with high vascularity in human burn wounds at day 7, further supporting our hypothesis that angiogenin is involved in burn wound neovascularization.

BACKGROUND: Hemianaesthesia patients usually exhibit awkward and inefficient finger movements of the affected hands. Conventionally, most interventions emphasize the improvement of motor deficits, but rarely address sensory capability and sensorimotor control following stroke. Thus it is critical for stroke patients with sensory problems to incorporate appropriate strategies for dealing with sensory impairment, into traditional hand function rehabilitation programs. In this study, we used a custom-designed computerized evaluation and re-education biofeedback (CERB) prototype to analyze hand grasp performances, and monitor the training effects on hand coordination for stroke patients with sensory disturbance and without motor deficiency. METHODS: The CERB prototype was constructed to detect momentary pinch force modulation for 14 sub-acute and chronic stroke patients with sensory deficiency and 14 healthy controls. The other ten chronic stroke patients (ranges of stroke period: 6-60 months) were recruited to investigate the effects of 4-weeks computerized biofeedback treatments on the hand control ability. The biofeedback procedures provide visual and auditory cues to the participants when the interactive force of hand-to-object exceeded the target latitude in a pinch-up-holding task to trigger optimal motor strategy. Follow-up measurements were conducted one month after training. The hand sensibility, grip forces and results of hand functional tests were recorded and analyzed. RESULTS: The affected hands of the 14 predominant sensory stroke patients exhibited statistically significant elevation in the magnitude of peak pinch force (p = 0.033) in pinching and lifting-up tasks, and poor results for hand function tests (p = 0.005) than sound hands did. In addition, the sound hands of patients were less efficient in force modulation (p = 0.009) than the hands of healthy subjects were. Training with the biofeedback system produced significant improvements in grip force modulation (p = 0.020) and better performances in the subtests of pin insertion (p = 0.019), and lifting of lightweight objects (p = 0.005). CONCLUSIONS: The CERB prototype can provide momentary and interactive information for quantitative assessing and re-educating force modulation appropriately for stroke patients with sensory deficits. Furthermore, the patients could transfer the learned strategy to improve hand function.
