ABSTRACT

Background: Microsurgical great toe-to-thumb transfer (mGTT) is a widely used procedure when immediate replantation of thumb is not feasible. The aim of this study was to investigate the alteration of plantar pressure profile of the donor foot after mGTT. Methods: Twenty patients receiving microsurgical great toe-to-hand transfer between 1985 to 2014, and 16 healthy subjects were recruited. Group 1 consisted of 20 feet receiving mGTT, whereas group 2 consisted of 32 normal feet as control. The flap design in this study was to preserve 1 cm of the proximal phalanx to maintain the attachment of the plantar aponeurosis and intrinsic muscles. The Taiwan Chinese version of the Foot Function Index was used for patient-reported outcome measurement. A novel Emed-X system was used for dynamic plantar pressure measurement. A total of four parameters were collected, including peak pressure, contact area, contact time, and pressure-time integral. Results: In group 1, the peak pressure redistributed under the first metatarsal bone and was significantly higher than group 2 (P < 0.05). There was no significant change of the contact area between the midfoot region of group 1 and group 2 (P > 0.05). Furthermore, similar foot clearance efficiency was demonstrated in group 1 and group 2 (P > 0.05). Conclusions: The windlass effect of the foot will not be affected when performing mGTT with preservation of 1 cm of the proximal phalanx. Therefore, this surgical procedure is highly recommended for clinical application.

ABSTRACT

INTRODUCTION: OnabotulinumtoxinA treatment for spasticity varies according to numerous factors and is individualized to meet treatment goals. OBJECTIVE: To explore real-world onabotulinumtoxinA utilization and effectiveness in patients with lower limb spasticity from the Adult Spasticity International Registry (ASPIRE) study. DESIGN: Two-year, multicenter, prospective, observational registry (NCT01930786). SETTING: Fifty-four international clinical sites. PATIENTS: Adults (naïve or non-naïve to botulinum toxin[s] treatment for spasticity, across multiple etiologies) with lower limb spasticity related to upper motor neuron syndrome. INTERVENTIONS: OnabotulinumtoxinA administered at the clinician's discretion. MAIN OUTCOME MEASURES: OnabotulinumtoxinA treatment utilization, clinician- and patient-reported satisfaction. RESULTS: In ASPIRE, 530 patients received ≥1 onabotulinumtoxinA treatment for lower limb spasticity (mean age, 52 years; stroke, 49.4%; multiple sclerosis, 20.4%). Equinovarus foot was treated most often (80.9% of patients), followed by flexed knee (26.0%), stiff extended knee (22.5%), and flexed toes (22.3%). OnabotulinumtoxinA doses ranged between 10 and 1100 U across all presentations. Electromyography (EMG) was most commonly used for injection localization (≥41.1% of treatment sessions). Despite low patient response on the satisfaction questionnaire, clinicians (94.6% of treatment sessions) and patients (84.5%) reported satisfaction/extreme satisfaction that treatment helped manage spasticity, and clinicians (98.3%) and patients (91.6%) would probably/definitely continue onabotulinumtoxinA treatment. These data should be interpreted with care. Twenty-one adverse events (AEs) in 18 patients (3.4%) were considered treatment-related. Sixty-seven patients (12.6%) reported 138 serious AEs; 3 serious AEs in two patients (0.4%) were considered treatment-related. No new safety signals were identified. CONCLUSIONS: ASPIRE provides long-term observational data on the treatment of lower limb spasticity with onabotulinumtoxinA. Real-world data from this primary analysis can help to guide the clinical use of onabotulinumtoxinA to improve spasticity management.

ABSTRACT

OBJECTIVE: The purpose of this study was to observe whether our custom made shoes and total contact insoles can effectively increase the plantar contact areas and reduce peak pressures in patients with leprosy. DESIGN: In the rehabilitation laboratory of a tertiary medical center. Six male and two female leprosy patients were recruited in this study. In this study, parameters related to foot pressures were compared between these patients wearing commercial available soft-lining kung-fu shoes and our custom made shoes with total contact insoles. The custom made shoes were made with larger toe box and were able to accommodate both the foot and the insoles. Custom made total contact insoles were made with the subtalar joints under neutral and non-weight-bearing positions. The insole force measurement system of Novel Pedar-X (Novel, Munich, Germany) was used to measure the plantar forces. The parameters of contact area (cm(2)), peak plantar pressures (kPa), contact time (s), and pressure time integral (kPa s) were measured. RESULTS: There were significant contact area increases in the right and left foot heel areas, left medial arch, and second to fifth toes after wearing the custom made shoes and insoles. There were significant decreases in peak plantar pressures in bilateral heels, left lateral midfoot, bilateral second to fourth metatarsal areas, and left fifth metatarsal head after wearing the custom made shoes and insoles (p<0.05). CONCLUSIONS: Plantar ulceration is a common serious disability in leprosy patients. As a result, footwear and measures able to reduce plantar pressures may be beneficial in preventing plantar ulcers from occurring in these patients. Our custom made shoes and total contact insoles were proven to be effective in increasing contact areas and decreasing peak pressures in plantar surfaces, and may therefore be a feasible treatment option in preventing leprosy patients from developing plantar ulcers.

ABSTRACT

OBJECTIVE: To evaluate the muscle activation pattern of lower extremities can be modified by intraarticular injection of hyaluronic acid( IAHA). MATERIAL AND METHOD: Twenty-three subjects with knee OA and 14 age-matched non-knee OA control subjects were recruited from an outpatient clinic. Three-dimensional gait analysis with using the MA- 100 EMG system was applied to measure the muscles activities. The quadriceps (QUA), hamstrings (HAM), tibialis anterior (TA), and medial gastrocnemius (MG) muscles were selected for this study. For the knee OA group, bilateral IA knee joint injections with HA were performed. RESULTS: During the stance phase of gait cycle, the quadriceps, hamstring, and tibialis anterior muscles had longer muscle contraction duration in the knee OA patients as compared with the control group. The muscle activities of quadriceps, hamstrings, tibialis anterior, and medial gastrocnemius muscles recovered to a pattern similar to the control group after the completion of IA HA injections in knee OA patients. The H/Q ratio improved significantly after the IA HA injections, and also lasted up to a period of six months (p<0.01). CONCLUSION: IA HA is an available treatment option as it effectively decreases co-contraction and improves motor activity of the lower extremity muscles. The improved muscle activities lasted up to a period up to six months.

ABSTRACT

OBJECTIVES: To examine the kinetic features in patients with knee osteoarthritis (OA) after intra-articular hyaluronic acid (IAHA) injections in different time periods. DESIGN: A single group repeated measures study. SETTING: Gait laboratory in a tertiary hospital. PARTICIPANTS: Twenty-five subjects with bilateral symptomatic knee OA and 15 healthy control subjects. INTERVENTION: Gait analyses were performed in both control and OA groups before (baseline), and after the completion of IAHA injections (1 week, 3 months, and 6 months). MAIN OUTCOME MEASURES: Knee pain and functional indices were assessed using a visual analogue scale (VAS) and the Lequesne function Index (LI). Joint kinetic changes were analyzed in the frontal and sagittal planes with 6-camera motion analysis system and two AMTI force plates. RESULTS: VAS and LI scores were both improved in OA group after IAHA injections (p<0.001). In the frontal plane, increased knee adduction moment (p<0.001) after IAHA treatment was observed and would last up to a period of 6 months. In the sagittal plane, lower knee extension moments at early stance, and larger knee flexion moments at terminal stance were demonstrated after the completion of IAHA injections (p<0.05). CONCLUSIONS: This study revealed that IAHA injections can provide significant pain relief and improvement in activity of daily living function for patients with knee OA. However, the reduction in pain and the increase in knee adduction moment may last up to 6 months. This may cause excessive loading on the knee joints, which may further accelerate the rate of knee degeneration. As a result, longer study time is needed to determine whether the observed kinetic findings in this study are associated with detrimental outcomes on the knee joints.

ABSTRACT

OBJECTIVE: To investigate the therapeutic effects of Botulinum toxin type A (BTA) for anterior knee pain caused by patellofemoral pain syndrome (PFPS). DESIGN: Prospective case control study for intervention. SETTING: A tertiary hospital rehabilitation center. PARTICIPANTS: Twelve bilateral PFPS patients with anterior knee pain were recruited. The worse pain knee was selected for injection, and the counterpart was left untreated. INTERVENTION: Injection of BTA to vastus lateralis (VL) muscle. MAIN OUTCOME MEASURES: Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was used to assess pain, stiffness, and functional status of the knee, and CYBEX isokinetic dynamometer to assess isokinetic muscle force before and after BTA application to VL. RESULTS: Remarkable improvement after receiving BTA injection was obtained not only in the questionnaire of WOMAC (p<0.05), but also in knee flexion torque (p<0.05). No significant change of knee extension torque was noted (p=0.682). CONCLUSION: BTA injection is a good alternative treatment to improve anterior knee pain, knee function and isokinetic flexion torque.

ABSTRACT

Tourette syndrome (TS) is a childhood-onset developmental disorder characterized by involuntary motor and vocal tics. Previous studies have indicated that children with TS demonstrate postural control anomalies when standing. The aim of this study was to compare postural stability under normal and altered sensory conditions in children with TS and healthy control (HC) children. A convenience sample of twelve children with TS (9 boys and 3 girls; 9.4 ± 1.1 yr) and 12 HC age- and gender-matched children (9.2 ± 1.1 yr) participated in this study. The Sensory Organization Test (SOT) was used to assess postural stability under six altered sensory conditions (1. normal vision, fixed support; 2. eyes closed, fixed support; 3. vision sway-referenced, fixed support; 4. normal vision, support sway-referenced; 5. eyes closed, support surface sway-referenced; 6. both vision and support surface sway-referenced) using the SMART Balance Master® 8.2 (NeuroCom® International, Inc, Clackamas, OR, USA). The results showed significant differences between the two groups in conditions 5 and 6 (p=0.003 and 0.002, respectively). The mean composite equilibrium score in children with TS was significantly lower than that of HC children (p<0.000). The results suggested that children with TS had greater difficulty in maintaining postural stability, especially when vestibular information was challenged. The results of this study provide supporting evidence for possible deficits in impaired access to vestibular information and sensorimotor integration of postural control in children with TS.

ABSTRACT

OBJECTIVE: The aim of the study was to compare the muscle activation feature of vastus medialis obliquus (VMO) and vastus lateralis (VL) between the osteoarthritic knee patients with patellar lateral subluxation (Group 1B) and without patellar lateral subluxation (Group 1A). METHODS: Isokinetic muscle strength of the knee extensor was evaluated using a CYBEX NORM dynamometer with angular velocities of 80, 120 and 240 degrees/second (°/sec) respectively, contraction activities of VMO and VL muscle were recorded with synchronized surface electromyography (sEMG). Age-matched healthy subjects were recruited and served as control group (Group 2). The VMO/VL ratio of EMG between Group 1A, Group 1B and Group 2 were compared. RESULTS: The peak torque in Group A was 40.7 ± 12.9, in Group B was 39.6 ± 12.9 and in Group C was 60.2 ± 9.5 respectively at 80°/sec angular velocity (p < 0.01). There were no significant difference between Group 1A and Group 1B in the three trial of tested velocities (p > 0.01). The sEMG ratios of VMO/VL of Group 1B calculated at angular velocities of 80/sec was 0.769 ± 0.15, 120°/sec was 0.818 ± 0.22 and 240°/ sec was 0.850 ± 0.22, all those were lower than Group 1A and Group 2 (p<0.01). CONCLUSION: Musculature imbalance of VMO and VL may explain the different muscle activation pattern in osteoarthritic knee patients with and without patellar lateral subluxation.

ABSTRACT

OBJECTIVE: Rehabilitation has been reported to improve pain and disability for patients after lumbar surgery. However, studies to investigate the rehabilitation intervention for lumbar decompression surgery during hospitalization are scarce. The aim of this study was to examine outcomes of perioperative rehabilitation intervention for patients who underwent lumbar decompression surgery (LDS). METHODS: Patients aged 18-65 years old who received their first LDS were randomized into the perioperative rehabilitation group (PG) or control group (CG). The PG received rehabilitation intervention during hospitalization for lumbar decompression surgery. Pain, functional capacity, Roland-Morris Disability Questionnaire (RMDQ), and Short-Form Health Survey (SF-12) were assessed on admission, at discharge, and at follow-ups one month, three months, and six months after surgery. Two-way repeated measures ANOVAs were used for statistical analysis. RESULTS: A total of 60 patients scheduled for decompression surgery for lumbar stenosis were enrolled into the study. After surgery, the PG showed significant pain relief and improvement of disability as well as quality of life, but there were no significant functional improvements compared with the CG. CONCLUSIONS: The findings of this study indicate that the rehabilitation intervention during hospitalization improves pain intensity as well as disability and quality of life, yet has limited effects on the functional performance over time up to six months post-surgery in patients who received LDS. The study suggest that rehabilitation interventions during hospitalization must include regular support for patient adherence to the intervention program and focus on task-oriented programs for lower extremities such as closed-chain exercises in functional postures.

ABSTRACT

OBJECTIVE: To describe the acquisition of anticipatory postural adjustment (APA) in healthy adults during standing forward reaching. DESIGN: Repeated-measures design Subjects/Patients: Ten healthy subjects. METHODS: Within one day, all subjects practiced forward reaching to a moving target for sixty trials (10 trials, 6 blocks). APAs were recorded by electromyography (EMG), center of pressure (COP), and kinematic measurements. Repeated measure ANOVA was used to compare the changes of APA among the six blocks. RESULTS: All subjects showed basic APA patterns in the beginning, such as posterior shift of COP and tibialis anterior firing first. The adults demonstrated significantly quicker onset of posterior shift of COP between block 2 and 6 (p<0.05) and decreased muscle activation of ispilateral tibialis anterior between block 1 and 3 (p=0.01). CONCLUSIONS: The results suggested the acquisition process of APA could be observed after 50 trials of practice. Further study will need to verify the optimal practice trials in different populations with movement disorders.

ABSTRACT

OBJECTIVE: To evaluate the effects of a custom-molded heel-elevated total contact insole (TCI) on rearfoot pressure reduction and heel cushion for patients with heel-reconstruction. METHODS: Eleven patients with unilateral heel-reconstruction were recruited in this study. Maximal force and plantar pressures (peak pressure and pressure-time integral) at three different areas (heel Midfoot and forefoot) were measured under 3 randomized conditions (shoe-only flat insole and heel- elevated TCI) after wearing a heel-elevated TCI for 3 months. Ulceration inspection and pain intensity were evaluated before and 3 months after wearing a heel-elevated TCI Results: Pain intensity was decreased and walking velocity was improved in all patients (p<0.01), and ulcerations were completely healed in all of the five patients who had heel ulcers 3 months after wearing heel-elevated TCIs. Compared to shoe-only condition, the heel-elevated TCI was effectively reduced maximal force and plantar pressures in heel area (p<0.01) while part of the body weight was shifted from heel to midfoot and forefoot. Plantar pressures in heel area were more effectively reduced in the heel-elevated TCI than in the flat insole (p<0.05). CONCLUSION: These findings suggested that heel-elevated TCI provided more effective heel pressure reduction and shock absorption, and resulted in improvement of clinical symptoms.

ABSTRACT

The purpose of this study is to evaluate the therapeutic effect of total contact insole with forefoot medial posting (TCIFMP) orthosis in patients with flexible flatfoot. The TCIFMP insole was custom- mode, made from semi-rigid plastazote and PPT. Using the gait analysis and the plantar-pressure measure systems, we investigate rearfoot motion and plantar pressure redistribution in these patients. The results of this study showed that the excessive valgus movement of the rearfoot can be reduced significantly by the TCIFMP insole in these patients. Besides, there were significant decreases in the peak pressure under the toe, lateral metatarsal, lateral foot and heel areas. Therefore, we suggested that the TCIFMP insole is an effective orthotic device for rearfoot motion control, plantar pressure reduction and re-distribution in patients with flexible flatfoot.

ABSTRACT

Earlier studies had suggested that variability of stride length in gait is a pathological sign of basal ganglia disease. Some evidence implicates the involvement of the basal ganglia and related thalamocortical circuitry in Tourette syndrome (TS). To date, the gait of subjects with TS has only discussed in case reports. This investigation compared the spatial and temporal gait characteristics of a sample of children with TS (N=8) with those of healthy controls (HC; N=8). All children were instructed to walk under two speed conditions: "preferred" and "fastest." Gait parameters were measured using an electronic walkway. Spatial and temporal gait parameters were compared using a two-way (group)×(conditions) repeated measures ANOVA. The preliminary results suggested that similar to HC children, children with TS were capable of regulating temporal characteristics of gait based on walking speed. They also exhibited subtle gait anomalies such as irregular step length, as evidenced by significant differences in step length differential (p=0.003), detectable despite the small sample size. These findings warrant further investigation into the gait control of children with TS.

ABSTRACT

Parental concern is a useful screening approach for early detection of children with developmental delay. We investigated the relationships among parental concerns, functional impairment, and final diagnosis of children (n = 273) with developmental delays. Of these, motor, language, and global delay were most common. Parental concerns, especially in language and motor development, were good predictors of children with language or motor delay, and provided reliable information for detection of children with delays in these domains. Parents were less likely to identify children with cognitive problems, global delay, or associated behavioral problems. Co-occurrence of developmental disorders was also recognized, especially in children with global delay. We conclude that parental concerns are useful information for detection of specific developmental problems in children. Because co-occurrence of developmental disorders is common, their early recognition would be helpful for better care of these children.

ABSTRACT

OBJECTIVE: The study attempted to evaluate the value of ultrasonography in determining the therapeutic strategy for patients with osseous injuries caused by ankle sprains. DESIGN: A 10-MHz compact linear-array ultrasound transducer was used to assess patients with inversion ankle sprains. Eleven female and 12 male patients who had fractures detected by sonograms were included in the study. All 23 patients underwent radiographic examination for identification of fractures. Bone scintigraphy was performed for those who had negative x-ray findings. RESULTS: Eighteen patients had distal fibular tip fractures, three patients had the fifth metatarsal base fractures, one patient had a talar neck fracture, and one patient had a navicular fracture. These fractures were all detected by ultrasonography and then proved even by radiography or by bone scans. All the 23 patients had anterior talofibular ligament injuries. Among these patients, 11 had anterior ankle-joint recess effusion, and two had additional anterioinferior tibiofibular ligament injuries. Six weeks of immobilization with the ankle fracture brace was prescribed for all the patients after the identification of fractures. Their ankle pain symptoms soon improved. CONCLUSIONS: Ultrasonography is valuable in evaluating tiny foot and ankle fractures and coexistent soft tissue injuries. It can guide the treatment for patients with osseous injuries caused by ankle sprains.

ABSTRACT

The aim of this study is to determine the predictive critical value of the Glasgow Coma Scale for use as a determinant of outcome for children with traumatic brain injuries. A total of 309 children, aged 2-10 years, were enrolled in this study. Each subject underwent the following assessments: Glasgow Coma Scale; clinical data; brain computed tomography; and Glasgow Outcome Scale assessments. The receiver operating characteristic curve indicated that a critical point of the Glasgow Coma Scale set at 5 was most strongly correlated with outcome of pediatric traumatic brain injury. Subarachnoid hemorrhage with brain swelling and edema, subdural, intracerebral hemorrhage, and basal ganglion lesions were associated with severe injury and poor outcome (P < 0.05). However, cortical lesions did not affect injury severity and outcome. In injuries associated with traumatic brain injuries, only chest trauma had a tendency to be associated with poor outcome (P < 0.05). Of the factors analyzed, the score of the Glasgow Coma Scale was the most effective predictor for outcome in pediatric traumatic brain injury. Furthermore, the predictive critical score of the Glasgow Coma Scale should be set at 5 for pediatric traumatic brain injury. The computed tomographic findings also were important in determining injury severity and predicting outcome.

ABSTRACT

PURPOSE: The purpose of the study was to determine the echogenicity and thickness of both the normal and injured posterior cruciate ligament (PCL). METHODS: Eight patients with anterior cruciate ligament injury received ultrasonographic evaluation during arthroscopic examination. With the aid of the comet-tail artifact produced by the metal hook during arthroscopic examination, the normal PCL was located on sonograms. Thereafter, 11 patients with PCL injury were examined. In all subjects, the PCL thickness was measured at 2.0 cm proximal from posterior end of the distal PCL inserting onto the tibia. RESULTS: The normal PCL was located just posterior to the posterior tibial intercondylar area. It was hypo-echoic and was thickened proximally and tapered distally. The mean thickness of the injured PCL was 0.71 +/- 0.12 cm, which was significantly (p < 0.05) greater than that of the normal ligament (0.52 +/- 0.08 cm). Different appearances could be observed, including ligamental rupture and avulsion fracture of the tibial insertion of the PCL. CONCLUSIONS: The normal PCL appears on longitudinal sonograms as a hypoechoic fan-shape structure. Sonographic examination can identify different types of PCL lesions.
