Factors influencing home discharge of hospitalized oldest-old patients (≥90 years): A retrospective quantitative case-control study.

The purpose of this retrospective study was to identify factors that could predict the discharge destination of oldest-old patients (patients aged ≥90 years). Information on the nutritional status, activities of daily living (ADL), nursing care needs based on nursing need degree (NND), rehabilitation therapy, and discharge destination was obtained from the medical records of 90 oldest-old patients aged ≥90 years admitted to our hospital, excluding orthopedic inpatients and short-term (≤5 days) inpatients. Of these, 64 were discharged home while 4 died during hospitalization. More than half had moderately low total lymphocyte count (<1200/µL). Home discharge was correlated with living with someone else and little need for assistance during eating and getting/standing-up at admission. The cutoff value for ability for basic movement scale (ABMS) at admission for home discharge was 18 points. Nutritional management and early mobilization are important aspects of clinical management of the oldest-olds.

Claw Toe: Anatomic Guide for Injection of Botulinum Toxin into Foot Muscles.

BACKGROUND: Poor response to injection of botulinum toxin (BoNT) into the flexor digitorum longus (FDL) muscle has been reported especially in patients with claw foot deformity. We previously advocated BoNT injection into the flexor hallucis longus (FHL) muscle in such patients. Here, we determined the functional and anatomical relationships between FHL and FDL. METHODS: Toe flexion pattern was observed during electrical stimulation of FHL and FDL muscles in 31 post-stroke patients with claw-foot deformity treated with BoNT. The FHL and FDL tendon arrangement was also studied in five limbs of three cadavers. RESULTS: Electrical stimulation of the FHL muscle elicited big toe flexion in all 28 cases examined and second toe in 25, but the response was limited to the big toe in 3. FDL muscle stimulation in 29 patients elicited weak big toe flexion in 1 and flexion of four toes (2nd to 5th) in 16 patients. Cadaver studies showed division of the FHL tendon with branches fusing with the FDL tendon in all five limbs examined; none of the tendons was inserted only in the first toe. No branches of the FDL tendon merged with the FHL tendon. CONCLUSION: Our results showed coupling of FHL and FDL tendons in most subjects. Movements of the second and third toes are controlled by both the FDL and FHL muscles. The findings highlight the need for BoNT injection in both the FDL and FHL muscles for the treatment of claw-toe deformity.

Botulinum toxin treatment for difficult-to-treat finger pressure ulcers caused by severe hand flexion: case report.

We report the successful treatment of two cases of difficult-to-treat pressure ulcers with botulinum toxin type A (BoNT-A). A 71-year-old male patient with Parkinson's disease presented with severe hand grip deformities of the fingers and a pressure ulcer (PU) on the right hand. He received 240U of BoNT-A into the upper limb muscles, which improved finger mobility during passive extension and resulted in resolution of the palm PU. No recurrence was noted. A 69-year-old female patient with Lewy body dementia presented with a PU on the palm side of the middle finger apex of the right hand, with exposure of the phalanx bone and dark red oedematous granulation of the tip of the finger. Severe muscle tone was noted. She received 240U of BoNT-A injected into the muscles of the upper extremities. This resulted in the disappearance of the contracture between the middle finger cusp and palm, and prompt healing of the PU. A protective finger orthosis was also used to improve hand finger grip and prevent further PUs. Although BoNT-A injection resulted in only slight improvement in the range of motion, it produced relief of pressure with consequent healing of the PU. Injection of BoNT-A into the affected muscles of the patients in this case report was effective in reducing flexor muscle tone, relief of pressure on the palm skin and healing of hand PUs.

Brain perfusion and upper limb motor function: a pilot study on the correlation between evolution of asymmetry in cerebral blood flow and improvement in Fugl-Meyer Assessment score after rTMS in chronic post-stroke patients.

BACKGROUND AND PURPOSE: Few studies have explored the refinement of asymmetry in regional cerebral blood flow in relation to behavioral improvement after treatment. The purpose of this retrospective pilot study was to identify cerebral cortical regions with improved perfusion that correlated with improvement of upper limb motor function after repetitive transcranial magnetic stimulation (rTMS). MATERIALS AND METHODS: The study subjects were 33 post-stroke patients with upper limb hemiparesis who underwent rTMS combined with intensive occupational therapy (mean ± SD age: 64.9 ± 11.2 years; time since onset of stroke: 57.3 ± 45.9 months). Fugl-Meyer Assessment (FMA) and the Wolf Motor Function Test (WMFT) were applied before and after treatment to evaluate motor function in the affected upper limb. Regional brain perfusion was measured by single-photon emission computed tomography, and the percentages of asymmetry values (asymmetry index [AI]) for 52 bilateral regions of interest were calculated. The change in AI was calculated as the post-intervention minus pre-intervention values. RESULTS: Changes in AI in the superior and middle frontal areas correlated significantly and negatively with changes in FMA score (superior: r = -0.406, P = 0.03, R(2) = 0.251; middle: r = -0.437, P < 0.001, R(2) = 0.306), but not with changes in WMFT log performance time. CONCLUSION: Changes in AI less than zero reflect improved perfusion, suggesting that upper limb motor function improvement in post-stroke patients reflects evolution of brain perfusion in the superior and middle frontal areas.

Gait Reconstruction Strategy Using Botulinum Toxin Therapy Combined with Rehabilitation.

Numerous studies have established a robust body of evidence for botulinum toxin A (BoNT-A) therapy as a treatment for upper motor neuron syndrome. These studies demonstrated improvements in spasticity, range of joint motion, and pain reduction. However, there are few studies that have focused on improvement of paralysis or functional enhancement as the primary outcome. This paper discusses the multifaceted aspects of spasticity assessment, administration, and rehabilitation with the goal of optimising the effects of BoNT-A on lower-limb spasticity and achieving functional improvement and gait reconstruction. This paper extracts studies on BoNT-A and rehabilitation for the lower limbs and provides new knowledge obtained from them. From these discussion,, key points in a walking reconstruction strategy through the combined use of BoNT-A and rehabilitation include: (1) injection techniques based on the identification of appropriate muscles through proper evaluation; (2) combined with rehabilitation; (3) effective spasticity control; (4) improvement in ankle joint range of motion; (5) promotion of a forward gait pattern; (6) adjustment of orthotics; and (7) maintenance of the effects through frequent BoNT-A administration. Based on these key points, the degree of muscle fibrosis and preintervention walking speed may serve as indicators for treatment strategies. With the accumulation of recent studies, a study focusing on walking functions is needed. As a result, it is suggested that BoNT-A treatment for lower limb spasticity should be established not just as a treatment for spasticity but also as a therapeutic strategy in the field of neurorehabilitation aimed at improving walking function.

Survey on diagnosis of post-brain injury "higher brain dysfunction" in patients with cognitive impairment. Family/caregiver response.

In Japan, the diagnostic criteria for the higher brain dysfunction (HBD) emerged in 2005 in response to social needs for support for the patients and their families. The issue of cognitive dysfunction after brain trauma is not unique to Japan. The purpose of this study was to reveal the current status of family members of HBD patients from their perspective, focusing on the changes before and after the establishment of diagnostic criteria in Japan. We conducted a questionnaire survey for family members supporting the HBD patients. The questionnaire included the causative condition, explanation on HBD by health professionals, and problems/difficulties they encountered. This research involved family members of 278 HBD cases (males = 211, age 49 years). The major underlying cause was head injury (n = 139). Compared to patients diagnosed pre-2005, a significantly larger proportion of family members after 2005 received information on the condition during the acute phase (within one month) (p < 0.001), including that from physicians (p < 0.001). Nearly half of the families cited a lack of awareness of HBD among the professionals as a problem. In Japan, awareness of HBD in the society is gradually increasing especially after the current diagnostic criteria were implemented, and there has been a steady increase over time in early diagnosis. Yet, there still remain those not appropriately diagnosed. To salvage those patients and the families left behind, we are suggesting several recommendations to further augment clinical practice and the healthcare systems in Japan.

A 10-Year Study of the Trend of Accidental Falls in the Elderly in a Japanese Hospital.

Elderly people are prone to falls. We established the Falls Prevention Working Group (FPWG) at our hospital in 2015 to reduce the number of falls during hospitalization. This study compared the trend of in-hospital falls in the elderly in two time periods (2008/9 and 2018/9) and determined the effects of FPWG-implemented measures. Using medical records, we counted the monthly number of falls suffered by patients during hospitalization in April 2008-March 2009 and April 2018-March 2019. We also categorized the falls according to the severity of fall-related complications.A total of 3609 hospital falls were recorded during the 2008-2019 period (2008/9: n = 433, 2018/9: n = 324). Falls were more common in patients aged 70-79 in 2008/9 but were noted in those aged ≥ 80 in 2018/9. The mean number of falls/month (27.3 ± 6.4, range: 12-45) was stable throughout the year. The incidence of falls in 2018/9 (1.90/1000 per persons per day) was significantly lower than in 2008/9 (2.30/1000, p = 0.006). Level ≥ 3b accidents, reflecting serious accidents with complications, were encountered in 12 of 433 accidents in 2008/9 compared with significantly fewer accidents (2 of the same severity among 324 accidents) in 2018/9 (p = 0.030).Our results showed a decrease in in-hospital falls in 2018/9 and that the sufferers were older relative to 10 years earlier. A multidisciplinary team should recommend measures to prevent falls and an environment "resilient" to falls, and encourage patients to be aware of possible falls.

Multimodal treatment, including extracorporeal shock wave therapy, for refractory chronic tension-type headache: a case report.

BACKGROUND: Few reports have described multidisciplinary treatment, including extracorporeal shock wave therapy, for patients with refractory chronic tension-type headache. In this study, we conducted multidisciplinary treatment for a patient with chronic tension-type headache who suffered from chronic headache refractory to treatment. CASE PRESENTATION: The patient was a 45-year-old Japanese male suffering from 20 years of headache. As his headache had worsened recently, he visited a local clinic. With the diagnosis of suspected tension-type headache, its treatment was unsuccessful and he was referred to our hospital. The neurology department confirmed the tension-type headache and prescribed another medication, but he showed no improvement. Then, the patient was referred to the rehabilitation medicine department for consultation. At the initial visit, we identified multiple myofascial trigger points in his bilateral posterior neck and upper back regions. At the initial visit, he was prescribed 10 mL of 1% lidocaine injected into the muscles in these areas. In addition, he received 2000 extracorporeal shock wave therapy into bilateral trapezius muscles, and was instructed to take oral Kakkonto extract granules, benfotiamine, pyridoxine hydrochloride, and cyanocobalamin. Cervical muscle and shoulder girdle stretches and exercises were also recommended. At follow-up treatment visits, we used extracorporeal shock wave therapy to bilateral trapezius muscles, which led to immediate pain relief. After 11 weeks, he was not taking any medication and his headache was subjectively improved and his medical treatment ended. CONCLUSION: A patient with chronic tension-type headache refractory to regular treatment was successfully treated with a multimodal approach including extracorporeal shock wave therapy in addition to standard treatment. For patients with tension-type headache accompanied by myofascial trigger points, it may be recommended to promptly consider aggressive multimodal treatment that includes extracorporeal shock wave therapy.

Treatment outcome of local injection of botulinum toxin for claw toe: Differences between cerebral hemorrhage and infarction.

BACKGROUND: Some patients with post-stroke claw toe respond well to botulinum toxin (BoNT) treatment while others do not. This study was designed to assess the impact of stroke type (cerebral hemorrhage and cerebral infarction) on the outcome of BoNT treatment for claw toe. METHODS: We retrospectively examined the medical records of patients who received local BoNT (onabotulinumtoxin A) injections into the flexor hallucis longus (FHL) and flexor digitorum longus (FDL) muscles. All patients suffered stroke-related leg paralysis and spasticity. RESULTS: The study participants were 58 patients (mean age, 61.4 ± 10.3 years, ± SD) with time since stroke of 6.7 ± 4.4 years. The stroke type was cerebral hemorrhage (n = 38) and cerebral infarction (n = 20). After a total of 124 BoNT administrations with medical records entries on the subjective symptoms, the odds for symptomatic improvement was approximately 5.8 times higher in patients of the infarction group compared with the hemorrhage group (OR = 5.787, 95% CI = 2.369-14.134, p = 0. 000). Fifty-one patients (32 with cerebral hemorrhage, 19 with cerebral infarction) received the first local BoNT injection and had available medical records, analysis of which showed a significantly higher rate of symptomatic improvement in patients of the infarction group than those of the hemorrhage group (p = 0.006). After adjustment by factors known to influence treatment outcome (degree of spasticity and paralysis, BoNT dosage, and extent of FDL muscle control of toe movements), the treatment effect was predominantly higher in patients with cerebral infarction. CONCLUSION: The BoNT treatment response was better for claw toes in cerebral infarction patients than in hemorrhage patients, possibly suggesting that claw toe is associated with more severe spasticity in this group of patients.

Comparison of the effect and treatment sequence between a 2-week parallel repetitive transcranial magnetic stimulation and rehabilitation and a 2-week rehabilitation-only intervention during a 4-week hospitalization for upper limb paralysis after stroke: An open-label, crossover observational study.

BACKGROUND: NEURO® is a 2-week program that combines low-frequency repetitive transcranial magnetic stimulation (rTMS) and intensive occupational therapy (OT) to treat patients with chronic hemiparesis following stroke. The degree to which each element contributes to the improvement of upper limb function remains unclear. It has been suggested that low-frequency rTMS applied to a healthy cerebrum activates neural activity in the contralateral hemispheric area surrounding the lesion. Intensive OT performed in parallel to rTMS promotes the functional remodeling of the cerebrum to help with rehabilitation. OBJECTIVES: However, this has not been demonstrated using NEURO®. Therefore, we aimed to compare the effects of the NEURO® and OT-only protocols in patients with hemiparesis following stroke. METHODS: Thirty-seven patients with upper limb paralysis following stroke were recruited and hospitalized for treatments and randomly divided into two groups. Group A consisted of 16 patients who underwent NEURO® for the first 2 weeks, and Group B consisted of 21 patients who underwent OT-only for the first 2 weeks. After 2 weeks of hospitalization, the treatments of Groups A and B were reversed for the subsequent 2 weeks of treatment. Improvement in upper limb motor function in Groups A and B at 2 and 4 weeks after the start of treatment was evaluated using the Fugl-Meyer Motor Assessment (FMA) and the Wolf Motor Function Test (WMFT). RESULTS: Group A, who underwent NEURO® first during their initial 2-week hospitalization, showed significantly greater improvement than that in Group B, who underwent OT-only first (P = .041 for FMA and P < .01 for WMFT). At 4 weeks following the reversal of treatments, Group A who underwent NEURO® and then OT-only showed significantly greater improvement than that in Group B, who underwent OT-only followed by NEURO® (P = .011 for FMA and P = .001 for WMFT). CONCLUSION: Our findings indicate that rTMS facilitates neuromodulation when combined with OT, which leads to more effective rehabilitation than with OT alone (Trial registration: JMACCT (http://www.jmacct.med.or.jp/); trial ID JMA-IIA00215).

Rehabilitation therapy for a severe case of coronavirus disease 2019: a case report.

BACKGROUND: Patients with severe coronavirus disease 2019 (COVID-19) infection require a long period of time to return to work and society due to significant physical weakness even after recovery. Here we report a patient with a history of nephrectomy who developed severe COVID-19 infection associated with muscle weakness but was able to return to society after rehabilitation therapy. CASE PRESENTATION: A Japanese man in his 40s was admitted to the hospital with PCR-based COVID-19 diagnosis. The respiratory condition worsened rapidly and was treated with extracorporeal membrane-assisted ventilation in the intensive case unit. On admission to the Rehabilitation Department on day T + 30 [T: day patient became febrile (38 °C)], he was unable to stand for a long time and used a walker. Rehabilitation therapy was postponed to prevent COVID-19 spread, but the patient was encouraged to exercise during isolation to improve trunk and lower extremity muscle strength. Physical therapy commenced on day T + 49 to improve gait and trunk and lower limb muscle strength. He was able to walk independently and later returned to work following discharge on day T + 53. A computed tomography scan showed an increase in psoas muscle volume from 276 before to 316 cm3 after physical therapy, together with a decrease in whole-body extracellular water:total body weight ratio from 0.394 to 0.389. CONCLUSIONS: We have described the beneficial effects of rehabilitation therapy in a patient with severe COVID-19 infection. In addition to exercise, we believe that nutrition is even more important in increasing skeletal muscle mass. Rehabilitation therapy is recommended to enhance the return of severely ill COVID-19 patients to routine daily activity.

Effects of Flexor Digitorum Longus Muscle Anatomical Structure on the Response to Botulinum Toxin Treatment in Patients with Post-Stroke Claw Foot Deformity.

(1) Background: The purpose of this retrospective case-control study was to determine the relationship between the control of toe movements by flexor hallucis longus (FHL) and flexor digitorum longus (FDL) muscles and the response to treatment with botulinum toxin (BoNT) in post-stroke patients with claw toe. (2) Methods: Subjects with stroke-related leg paralysis/spasticity and claw toes received multiple injections of BoNT (onabotulinumtoxin A) into the FHL or FDL muscles. We investigated the relationship between the mode of transmission of FHL and FDL muscle tension to each toe (MCT) and treatment outcome using the data of 53 patients who received 124 injections with clinically recorded treatment outcome. We also dissected the potential variables that could determine the treatment outcome. (3) Results: The effectiveness of BoNT treatment was significantly altered by FDL-MCT (OR = 0.400, 95% CI = 0.162-0.987, p = 0.047). Analysis of the response to the first BoNT injection showed an odds ratio of FDL-MCT of approximately 6.0 times (OR = 0.168, 95% CI = 0.033-0.857, p = 0.032). The more tibial the influence of the FDL muscle on each toe, the better the treatment outcome on the claw toe. (4) Conclusions: The anatomic relation between FDL muscle and each toe seems to affect the response to treatment with BoNT in post-stroke patients with claw toes.

Long-term effects of injection of botulinum toxin type A combined with home-based functional training for post-stroke patients with spastic upper limb hemiparesis.

The aim of this study was to assess the effects of botulinum toxin type A (BoNT-A) injection with home-based functional training for passive and active motor function, over a 6-month period in post-stroke patients with upper limb spasticity. We studied 190 patients with at least 6-month history of stroke. They received injections of BoNT-A in upper limb muscles and detailed one-to-one instructions for home-based functional training. At baseline (before therapy), and at 1-, 3- and 6-month follow-up, Fugl-Meyer assessment (FMA) and Wolf motor function test (WMFT) were used to assess active motor function, the modified Ashworth scale (MAS) for assessment of spasticity, and the range of motion (ROM) for passive motor function. The total score for upper limb and scores of categories A and B of the FMA increased significantly at 1, 3 and 6 months, while the FMA score for category D increased significantly at 3 and 6 months, but not at 1 month. Significant decreases in the MAS scores were noted in all muscles examined at 1, 3 and 6 months, compared with baseline. The ROM for elbow joint extension significantly improved at 1, 3, and 6 months, while that for wrist joint extension increased significantly at 1 month, but not 3 or 6 months, compared with baseline. The results suggest that comprehensive improvement of motor function requires improvement of motor function in the proximal part of the upper limb and that BoNT-A followed by rehabilitation reduces spasticity and improves motor function of fingers.

Botulinum toxin type A injection, followed by home-based functional training for upper limb hemiparesis after stroke.

Botulinum toxin type A (BoNT-A) has been reported to be an effective treatment for limb spasticity after stroke. However, the reduction in the spasticity after BoNT-A injection alone does not ensure an improvement in the active motor function of the affected limb. The aim of this study was to clarify the clinical effects of a BoNT-A injection, followed by home-based functional training on not only the passive but also the active motor function of the affected spastic upper limb in poststroke hemiparetic patients. Eighty poststroke patients with spastic upper limb hemiparesis were studied. The severity of hemiparesis was categorized as Brunnstrom stage of 3 for hand-fingers in all patients. BoNT-A (maximum dose of 240 U) was injected into the target muscles of the affected upper limb after a clinical evaluation using the modified Ashworth scale, range of motion, Fugl-Meyer Assessment, and the Wolf Motor Function Test. Following the injection, occupational therapists provided home-based functional training for each patient on a one-to-one basis. The follow-up evaluation was performed 4 weeks after the injection. A significant improvement was found in the modified Ashworth scale and range of motion. The changes in the Fugl-Meyer Assessment and the Wolf Motor Function Test indicated a significant improvement in the active motor function of the affected upper limb. In conclusions, our proposed protocol of a BoNT-A injection, followed by home-based functional training seems to have the potential to improve the active motor function of the affected upper limb after stroke, although the efficacy should be confirmed in a randomized-controlled trial.
