Population based norms for the box and blocks test in healthy right-handed Taiwanese adults

BackgroundThis study establishes norms for the Box and Block Test (BBT) in healthy Taiwanese adults between 15 and 75 years of age. Methods621 right-handed healthy adults (296 males and 325 females) completed the study. All participants performed the BBT following the standard protocol. An age by gender by testing hand analysis of variance (ANOVA) was performed to determine differences for the variables of interest. ResultsOn average, females performed better on the BBT than males by approximately 2 points (p < 0.001). Across all participants, dominant hand performance was 2.8 points higher than non-dominant hand performance (p < 0.001). Significant changes of BBT scores across life span were observed at the ages of 30, 45 and 60 years old. Average scores across all age groups are at least one standard deviation below the previously established American norms for each corresponding age group. ConclusionWhen using the BBT test with adult Taiwanese clients, clinical practitioners should strongly consider using right-handed normative data from Taiwanese individuals as the norms for this population differ from the previously established norms from American adult participants.

Box and block test, hand grip strength and nine-hole peg test: correlations between three upper limb objective measures in multiple sclerosis.

Limited data are available in the literature for upper limb impairment in multiple sclerosis (MS). This study aimed to report the distribution of values of hand grip strength (HGS), of the box and block test (BBT) and of the nine-hole peg test (9HPT) correlated with demographic and clinical data in subjects with MS. This study involved five Italian neurological centres. The inclusion criteria were age ≥18, MS diagnosis, stable disease phase, right-hand dominance. All subjects underwent HGS, BBT and 9-HPT evaluation. In all, 202 subjects with MS were enrolled: 137 females; mean age 48.4years; mean Expanded Disability Status Scale (EDSS) 4.17; mean disease duration 14.12years; disease course 129 relapsing-remitting, 21 primary progressive and 52 secondary progressive MS subjects; mean right HGS 25.3 kg, left 23.2 kg; mean right BBT 45.7 blocks, left 44.9 blocks; mean right 9-HPT 30.7 s, left 33.4 s. All results were statistically significantly different compared to healthy controls. HGS, BBT and 9-HPT were associated with age, EDSS and disease duration, whilst disease course correlated with BBT and 9-HPT. The BBT and 9-HPT scores significantly differed according to level of disability (EDSS ≤3.0, 3.5-5.5, ≥6.0). Hand grip strength and BBT value distribution in a large MS population is reported. Correlations between HGS, BBT and 9-HPT were generally low.

Non-immersive Virtual Reality Rehabilitation Applied to a Task-oriented Approach for Stroke Patients: A Randomized Controlled Trial.

Virtual reality (VR) training allows the creation of the most applicable practice environment incorporated into computer-generated multisensory imagery. The purpose of this study was to investigate the effects of a virtual training program based on a RAPAEL smart glove on the upper extremity function and quality of life of community-dwelling individuals with chronic hemiparetic stroke. Thirty-six outpatients diagnosed as having a first stroke were selected to receive a therapeutic rehabilitation program at local rehabilitation units. Participants were allocated randomly into two groups: the non-immersive VR training (intervention) group and the recreational activity (control) group. The intervention group received non-immersive VR training using a RAPAEL smart glove for 30 minutes per session, 3 days a week for 8 weeks. The control group performed recreational activities for the same period and also participated in a conventional rehabilitation program for 30 minutes per session, 3 days a week for 8 weeks as an additional therapy. To analyze the effects of the non-immersive VR intervention on upper extremity function, four clinical measures, namely the box and block test (BBT), the Wolf motor function test (WMFT), the Jebsen-Taylor hand function test (JTT), and a grip strength test, were used in this study. For the secondary clinical outcome, the trail-making test (TMT) was used to determine any improvement in cognitive function. At week 8, upon completion of the non-immersive VR-training the intervention group demonstrated significantly greater WMFT scores (73.0±12.9 to 81.6±7.5), BBT scores (27.3±8.9 to 34.2±7.1), and grip strength (19.2±8.2 to 23.8±8.5) compared with WMFT scores (70.4±12.1 to 73.2±13.1), BBT scores (27.1±10.5 to 28.8±12.9), and grip strength (18.4±4.2 to 18.3±4.9) in the control group. This study suggests that virtual upper extremity training using the RAPAEL smart glove has reasonable and beneficial effects on upper extremity and cognitive function for chronic hemiparetic stroke survivors.

Functional and structural asymmetry in primary motor cortex in Asperger syndrome: a navigated TMS and imaging study

Motor functions are frequently impaired in Asperger syndrome (AS). In this study, we examined the motor cortex structure and function using navigated transcranial magnetic stimulation (nTMS) and voxel-based morphometry (VBM) and correlated the results with the box and block test (BBT) of manual dexterity and physical activity in eight boys with AS, aged 8–11 years, and their matched controls. With nTMS, we found less focused cortical representation areas of distinct hand muscles in AS. There was hemispheric asymmetry in the motor maps, silent period duration and active MEP latency in the AS group, but not in controls. Exploratory VBM analysis revealed less gray matter in the left postcentral gyrus, especially in the face area, and less white matter in the precentral area in AS as compared to controls. On the contrary, in the right leg area, subjects with AS displayed an increased density of gray matter. The structural findings of the left hemisphere correlated negatively with BBT score in controls, whereas the structure of the right hemisphere in the AS group correlated positively with motor function as assessed by BBT. These preliminary functional (neurophysiological and behavioral) findings are indicative of asymmetry, and co-existing structural alterations may reflect the motor impairments causing the deteriorations in manual dexterity and other motor functions commonly encountered in children with AS.

Cognitive strategy on upper extremity function for stroke: A randomized controlled trials.

Cognitive orientation to daily occupational performance (CO-OP) is a task-specific training applied using a cognitive behavioral approach to improve performance in daily activities and to enable the patient to overcome limitations related to them. The purpose of this study was to investigate the effects of the CO-OP approach in comparison with task-specific upper extremity training (TUET) on performance related to daily and functional activities in individuals with chronic hemiparetic stroke. Forty-nine participants diagnosed with stroke for the first time underwent 30 minutes of either the CO-OP approach or TUET 5 days a week for 4 weeks. We evaluated their performance on the box-and-block test (BBT), Canadian occupational performance measure (COPM), and community integration questionnaire (CIQ) and Wolf motor function test-functional score (WMFT-F) before and after the training. Our results show a significantly improvement in the WMFT-F, COPM-P, COPM-S, BBT, and CIQ scores after training in the CO-OP group, but only COPM-S score was significantly improvement after training in TUET group (p < 0.05). This study also found higher increases in the mean WMFT-F, COPM-P, COPM-S and BBT scores in the CO-OP group than in the TUET group, but CIQ score did not have a significantly higher increase between-group after training. The results of this study suggest that the CO-OP approach resulted in a positive therapeutic effect on self-selected occupational performance and daily and functional activities in individuals with chronic hemiparetic stroke.

Controlling pre-movement sensorimotor rhythm can improve finger extension after stroke

Objective. Brain–computer interface (BCI) technology is attracting increasing interest as a tool for enhancing recovery of motor function after stroke, yet the optimal way to apply this technology is unknown. Here, we studied the immediate and therapeutic effects of BCI-based training to control pre-movement sensorimotor rhythm (SMR) amplitude on robot-assisted finger extension in people with stroke. Approach. Eight people with moderate to severe hand impairment due to chronic stroke completed a four-week three-phase protocol during which they practiced finger extension with assistance from the FINGER robotic exoskeleton. In Phase 1, we identified spatiospectral SMR features for each person that correlated with the intent to extend the index and/or middle finger(s). In Phase 2, the participants learned to increase or decrease SMR features given visual feedback, without movement. In Phase 3, the participants were cued to increase or decrease their SMR features, and when successful, were then cued to immediately attempt to extend the finger(s) with robot assistance. Main results. Of the four participants that achieved SMR control in Phase 2, three initiated finger extensions with a reduced reaction time after decreasing (versus increasing) pre-movement SMR amplitude during Phase 3. Two also extended at least one of their fingers more forcefully after decreasing pre-movement SMR amplitude. Hand function, measured by the box and block test (BBT), improved by 7.3 ± 7.5 blocks versus 3.5 ± 3.1 blocks in those with and without SMR control, respectively. Higher BBT scores at baseline correlated with a larger change in BBT score. Significance. These results suggest that learning to control person-specific pre-movement SMR features associated with finger extension can improve finger extension ability after stroke for some individuals. These results merit further investigation in a rehabilitation context.

The effect of dynamic elastomeric fabric orthosis (DEFO) on sitting balance and gross manual dexterity in children with cerebral palsy: A single-blinded randomized controlled study

The aim of this study was to investigate if the use of a vest type dynamic elastomeric fabric orthosis (DEFO) will lead to improvement in sitting balance, hip lateralization and gross manual dexterity. Twenty-four children with CP between the ages of 3–7 with impaired trunk control were allocated to either of three groups: Control group who received only conventional exercise therapy, DEFO 2 hours group who wore DEFO 2 hours during therapy and DEFO 6 hours group who wore DEFO 4 hours in addition to 2 hours of wear during therapy. Children were evaluated with sitting domain of Gross Motor Function Measure (GMFM), Sitting Assessment Scale (SAS), Box and Block Test (BBT) and Parent Satisfaction Questionnaire before treatment (BT), at posttreatment, at 1 month posttreatment (MPT) and at 3 MPT. SAS and BBT were also assessed when immediately after wearing the orthosis. To measure trunk asymmetry and effect of orthosis in hip lateralization, changes in Cobb (CA) and kyphotic angles (KA) and Migration index (MI) between BT and 6 MPT were determined. All groups showed similar improvements except the control group showing less improvement in SAS scores than DEFO groups. SAS and BBT scores also improved immediately after wearing the orthosis. While CA and KA decreased significantly at 6 MPT, MI did not show statistically significant difference. Changes in radiographic assessments were similar between groups except kyphotic angle values. KA values showed less change in control group. When DEFO groups compared with each other, there were no significant differences in any of the assessments. DEFO vest has an immediate effect on sitting balance and gross manual dexterity. DEFO provides improvements in posture and balance during sitting. Using DEFO vest for 2 hours and 6 hours yielded similar outcomes. Wearing DEFO vest improves kyphotic posture but not scoliosis and hip lateralization.

Effects of live and video form action observation training on upper limb function in children with hemiparetic cerebral palsy.

The purpose of this study was to investigate the effects of live and video form action observation training (AOT) on upper limb (UL) movement acceleration and function in children with cerebral palsy (CP). In total, 12 children (7 boys, 5 girls) with CP participated in this study. The children were allocated randomly to live (experimental) and video (control) AOT groups. All children completed 20 treatment sessions, each 30 minutes in duration, 5 days per week for a month. Mediolateral (ML) and vertical (VT) acceleration data, Jebsen-Taylor Hand Function (JTHF) scores, and Box and Block Test (BBT) scores were obtained at baseline and at 4 weeks after the intervention. ML and VT movement acceleration and JTHF scores were significantly lower in the live group (p< 0.05). The BBT score was significantly higher in the live than in the video group (p< 0.05). Our findings suggest that live AOT is more effective than video AOT for improving UL movement acceleration and function. Clinically, our findings offer important insights for clinicians when planning AOT interventions to reduce UL movement acceleration and improve UL function.

Predictors of activities of daily living outcomes after upper limb robot-assisted therapy in subacute stroke patients.

BackgroundUpper limb recovery is one of the main goals of post-stroke rehabilitation due to its importance for autonomy in Activities of Daily Living (ADL). Although the efficacy of upper limb Robot-assisted Therapy (RT) is well established in literature, the impact of the initial status of the patient on the effects of RT is still understudied. This paper aims to identify whether demographic, clinical and motor characteristics of stroke patients may influence the ability to independently perform ADL after RT.MethodsA retrospective study was conducted on sixty stroke patients who conducted planar upper limb goal-directed tasks with the InMotion 2.0 robot. The RT was administered 5 days/week for 4 weeks and each session lasted 45 minutes. The primary outcome measure was the Modified Barthel Index (BI), dichotomized into favourable (BI ≥75) and unfavourable (BI<75) outcomes. The potential predictors were the demographic and clinical records, and the following clinical assessment scores: Modified Ashworth Scale-Shoulder (MAS-S); Modified Ashworth Scale-Elbow (MAS-E); Fugl-Meyer Assessment Upper Extremity (FMA-UE); upper limb section of the Motricity Index (MIul); total passive Range Of Motion (pROM); and Box and Block Test (BBT).ResultsStatistical analysis showed that the BBT, FMA-UE and MIul scores were significant predictors of a favourable outcome in ADL. The cut-off scores of the independent variables were calculated (FMA-UE = 32; MIul = 48; BBT = 3) with respect to the dichotomic BI outcome. Their robustness was assessed with the Fragility Index (FMA-UE = 2; MIul = 3; BBT = 7), showing that BBT is the most robust predictor of favourable BI outcome. Moreover, subjects with all predictors higher than the cut-off scores had higher probability to increase their independence in ADL at the end of the therapy. Demographic records, spasticity and pROM were not identified as predictors.ConclusionStroke patients with greater manual dexterity and less impairment appear to have a higher probability of achieving clinically significant ADL outcomes after upper limb RT. The obtained results can help to optimise the management of RT treatment planning. Further studies on a larger number of patients with a long-term follow up are recommended in order to evaluate other potential predictors and to validate the results.

Effectiveness of Bilateral Arm Training for Improving Extremity Function and Activities of Daily Living Performance in Hemiplegic Patients

Bilateral movement therapy, which encourages simultaneous use of the limbs on both the affected and nonaffected sides, is known to help in motor function recovery in hemiplegic patients. However, studies on the effectiveness of bilateral arm training for improving upper limb function and activities of daily living (ADL) performance in hemiplegic stroke patients are lacking. The present study investigated the effectiveness of bilateral arm training for improving upper limb function and ADL performance in hemiplegic stroke patients. The study included 30 hemiplegic stroke patients. The patients were randomly divided into an experimental group (n = 15) and a control group (n = 15). All patients received a uniform general occupational therapy session lasting 30 minutes 5 times a week for 8 weeks. The experimental group received an additional session of bilateral arm training lasting 30 minutes, and the control group received an additional session of general occupational therapy lasting 30 minutes. The Fugl-Meyer assessment (FMA), Box and Block Test (BBT), and modified Barthel index (MBI) were used for evaluation. In both the experimental and control groups, the FMA, BBT, and MBI scores were significantly higher after the intervention than before the intervention (P <.05). The changes in the FMA, BBT, and MBI scores were greater in the experimental group than in the control group (P <.05). Bilateral arm training along with general occupational therapy might be more effective than occupational therapy alone for improving upper limb function and ADL performance in hemiplegic stroke patients.

Influence of Motor Cortex Stimulation During Motor Training on Neuroplasticity as a Potential Therapeutic Intervention

ABSTRACTRehabilitation options to promote neuroplasticity may be enhanced when patients are engaged in motor practice during repetitive transcranial magnetic stimulation (rTMS). Twelve participants completed 3 separate sessions: motor practice, motor practice with rTMS, and rTMS only: motor practice consisted of 30 isometric contractions and subthreshold rTMS was 30, 3-s trains at 10 Hz. Assessments included the Box and Block Test (BBT), force steadiness (10% of the maximum voluntary contraction), and TMS (cortical excitability, intracortical inhibition, and intracortical facilitation). Participants significantly increased BBT scores following the combined condition. Force steadiness improved after all 3 conditions (p < .05). TMS outcomes depended on intervention condition with significant increases in facilitation following the motor practice plus rTMS condition. All interventions influenced motor control, yet are likely modulated differently when combining motor practice plus rTMS. These results help guide the clinical utility of rTMS as an intervention to influence motor control.

Intermanual Transfer Effects in Below-Elbow Myoelectric Prosthesis Users

ObjectivesTo determine intermanual transfer effects in patients with a below-elbow amputation using a myoelectric prosthesis and to establish whether laterality affects these effects. DesignCase-control. SettingA standardized setting in a rehabilitation clinic. ParticipantsA convenience sample (N=44) of experienced myoelectric prosthesis users (n=22) and matched controls (n=22). Controls were matched on sex, age (±5y), and hand dominance. InterventionsBoth the experienced group and the control group performed several tasks using a prosthesis simulator attached to their nonaffected arm. Main Outcome MeasuresMovement time, force control, Box and Block test (BBT) scores, and duration of hand opening. ResultsMovement times of myoelectric prosthesis users were shorter, and these users had significantly higher BBT scores and shorter hand opening durations than those of controls. No intermanual transfer effects on force control and no laterality effects were found. ConclusionsIntermanual transfer effects were present in experienced myoelectric prosthesis users with a below-elbow amputation, independent of laterality. These findings support the clinical relevance of intermanual transfer training, which may facilitate persons with an upper limb amputation to start training directly after the amputation.

Effects of action observation therapy on hand dexterity and EEG-based cortical activation patterns in patients with post-stroke hemiparesis

Background: Previous reports have suggested that action observation training (AOT) is beneficial in enhancing the early learning of new motor tasks; however, EEG-based investigation has received little attention for AOT.Objective: The purpose of this study was to illustrate the effects of AOT on hand dexterity and cortical activation in patients with post-stroke hemiparesis.Method: Twenty patients with post-stroke hemiparesis were randomly divided into either the experimental group (EG) or control group (CG), with 10 patients in each group. Prior to the execution of motor tasks (carrying wooden blocks from one box to another), subjects in the EG and CG observed a video clip displaying the execution of the same motor task and pictures showing landscapes, respectively. Outcome measures included the box and block test (BBT) to evaluate hand dexterity and EEG-based brain mapping to detect changes in cortical activation.Results: The BBT scores (EG: 20.50 ± 6.62 at pre-test and 24.40 ± 5.42 at post-test; CG: 20.20 ± 6.12 at pre-test and 20.60 ± 7.17 at post-test) revealed significant main effects for the time and group and significant time-by-group interactions (p < 0.05). For the subjects in the EG, topographical representations obtained with the EEG-based brain mapping system were different in each session of the AOT and remarkable changes occurred from the 2nd session of AOT. Furthermore, the middle frontal gyrus was less active at post-test than at pre-test.Conclusions: These findings support that AOT may be beneficial in altering cortical activation patterns and hand dexterity.

Immediate effects of somatosensory stimulation on hand function in patients with poststroke hemiparesis: a randomized cross-over trial.

This study aimed to determine the immediate effects of somatosensory stimulation on hand function in patients with poststroke hemiparesis. Eleven patients with poststroke hemiparesis participated in this study. Four types (no stimulation, vibration, and light and rough touches) of somatosensory stimulation were performed randomly for 4 days applying only one type of somatosensory stimulation each day. The box and block test (BBT), the Jebsen-Taylor hand function test (JTHFT), hand grip strength (HGS), and movement distance and peak velocity of the wrist joint during a forward-reaching task were measured. The BBT and JTHFT scores for no stimulation [BBT: median (interquartile range), 0.00 (-1.00 to 1.00) and JTHFT: 2.57 (-0.47 to 4.92)] were significantly different from those for vibration [BBT: 3.00 (2.00-5.00) and JTHFT: -16.02 (-23.06 to -4.31)], light touch [BBT: 3.00 (1.00-4.00) and JTHFT: -5.00 (-21.20 to -0.94)], and rough touch [BBT: 2.00 (1.00-4.00) and JTHFT: -6.19 (-18.22 to -3.70)]. The JTHFT score was significantly higher for vibration than that for rough touch (P<0.05). The increase in HGS was significantly greater for light touch than that for no stimulation (P<0.05) and for vibration than that for light touch (P<0.05). There were significant differences for the sagittal and coronal planes in movement distance and for the sagittal and horizontal planes in peak velocity during the forward-reaching task (P<0.05). The findings suggest that somatosensory stimulation may be advantageous to improve the hand function of patients with poststroke hemiparesis, with more favorable effects observed in vibration stimulation.

고유수용성신경근 촉진법 훈련과 동작관찰 훈련이 뇌졸중 환자의 상지 운동기능에 미치는 효과: 단일사례 연구

This study evaluated and compared the effectiveness on upper motor extremity function between proprioceptive neuromuscular facilitation which has been frequently used in clinical practice, and action observation training in terms of improving upper motor extremity function. A study with a single-subject design (A-B-C-A`) was conducted with a patient who was diagnosed with left hemiplegia. A repeated-measure analysis was conducted to assess results of the Wolf Motor Function Test (WMFT), Box and Block Test (BBT), and grip and pinch strength test performed daily in the study for 4 weeks. The results of the analysis indicated that the WMFT score, BBT score, grip strength, and pinch strength were improved from 29.60 to 39 (24.10%), from 1.67 to 4.93 each (EA) (66.22%), from 2.06 to 2.66 libras (lbs) (22.61%), and from 1.57 to 1.93 lbs (18.94%), respectively, from the baseline period to treatment period B. The values were improved from 29.60 to 42.20 (29.86%), from 1.67 to 7 EA (76.21%), from 2.06 to 3.47 lbs (40.57%), and from 1.57 to 1.67 lbs (6.12%), respectively, from the baseline period to treatment period C. From treatment period B to treatment period C, the WMFT score, BBT score, and grip strength were improved from 39 to 42.20 (7.58%), from 4.93 to 7 EA (29.56%), and from 2.66 to 3.47 lbs (23.20%), respectively, but pinch strength was decreased from 1.93 to 1.67 lbs (15.83%). In conclusion, proprioceptive neuromuscular facilitation and action observation training both have positive effects on upper extremity motor function. However, we suggest that the posttreatment effect of action observation training was better than that of proprioceptive neuromuscular facilitation.

The impact of high-frequency magnetic stimulation of peripheral nerves: muscle hardness, venous blood flow, and motor function of upper extremity in healthy subjects.

The purpose of this study was to investigate the impact of high-frequency peripheral nerve magnetic stimulation on the upper limb function. Twenty-five healthy adults (16 men and 9 women) participated in this study. The radial nerve of the non-dominant hand was stimulated by high-frequency magnetic stimulation device. A total of 600 impulses were applied at a frequency of 20 Hz and intensity of 1.2 resting motor threshold (rMT). At three time points (before, immediately after, and 15 min after stimulation), muscle hardness of the extensor digitorum muscle on the stimulated side was measured using a mechanical tissue hardness meter and a shear wave imaging device, cephalic venous blood flow on the stimulated side was measured using an ultrasound system, and the Box and Block test (BBT) was performed. Mechanical tissue hardness results did not show any significant differences between before, immediately after, and 15 min after stimulation. Measurements via shear wave imaging showed that muscle hardness significantly decreased both immediately and 15 min after stimulation compared to before stimulation (P < 0.05). Peripheral venous blood flow and BBT score significantly increased both immediately and 15 min after stimulation compared to before stimulation (P < 0.01). High-frequency peripheral nerve magnetic stimulation can achieve effects similar to electrical stimulation in a less invasive manner, and may therefore become an important element in next-generation rehabilitation.

NMES with rTMS for moderate to severe dysfunction after stroke.

Motor dysfunction after stroke might be improved by neuromuscular electrical stimulation (NMES) combined with 1 Hz repetitive transcranial magnetic stimulation (rTMS) in patients with moderate and severe motor dysfunction. This preliminary study tested the effect of this treatment combination. Fifteen patients (60.5 ± 10.3 years old) participated in the study. All patients had been affected by cerebral artery infarction or hemorrhage and had moderate or severe motor dysfunction in their affected hand. The patients received NMES at paretic wrist extensor muscles combined with rTMS over the unaffected M1 hemisphere twice a day, six days/week over two weeks. All participants underwent the following battery of tests to evaluate the motor function of the affected hand: Upper limb Fugl-Meyer Assessment (UFMA), Wolf Motor Function Test (WMFT), and Box and Block Test (BBT). UFMA, WMFT, and BBT scores improved significantly after the study. These results suggest that NMES combined with rTMS could be useful for recovery of moderate and severe motor function after stroke.

Predictors of Motor, Daily Function, and Quality-of-Life Improvements After Upper-Extremity Robot-Assisted Rehabilitation in Stroke

A subgroup of patients benefiting most from robot-assisted therapy (RT) has not yet been described. We examined the predictors of improved outcomes after RT. Sixty-six patients with stroke receiving RT were analyzed. The outcome measures were the Fugl-Meyer Assessment (FMA), Wolf Motor Function Test (WMFT), Motor Activity Log (MAL), and Stroke Impact Scale (SIS). The potential predictors were age, side of lesion, time since onset, Modified Ashworth Scale (MAS) scores, accelerometer data, Box and Block Test (BBT) scores, and kinematic parameters. BBT scores were predictive of FMA (29%) and MAL (9%-15%) improvements. Reduced shoulder flexion synergy, as measured by less shoulder abduction during forward reach, and MAS-distal were predictive of WMFT-function improvements. MAS-distal was predictive of SIS-physical improvements. Demographic variables did not predict outcomes. Manual dexterity was a valuable predictor of motor impairment and daily function after RT. Outcomes at different levels may have different predictors.

Action Observation Therapy in the Subacute Phase Promotes Dexterity Recovery in Right-Hemisphere Stroke Patients

The clinical impact of action observation (AO) on upper limb functional recovery in subacute stroke patients is recent evidence. We sought to test the hypothesis that training everyday life activities through AO coupled with task execution might activate the left hemisphere different from the right one. Sixty-seven first-ever ischemic stroke subjects were randomly assigned to receive upper limb training coupled with AO tasks or standard rehabilitation. The groups were matched by age and gender, Bamford category, and interval from stroke and lesion side. Fugl-Meyer (FM) and Box and Block Test (BBT) were used to measure hand function recovery at the end (T1) and 4-5 months after the treatment (T2). At T1, FM was increased by 31% (±26%), of maximum achievable recovery, whereas BBT was increased by 17% (±18%); at T2, FM had reached 43% (±45%) of maximum recovery, while BBT had reached 25% (±22%). Combining the effects of treatment to those of lesion side revealed significantly higher gains, in both FM and BBT scores, in left hemiparetic subjects when exposed to AO as compared to standard rehabilitation alone (P < .01). The findings lead to recommend the use of AO in addition to motor training in left hemiparetic patients.

Effects of Task-oriented Approach on Affected Arm Function in Children with Spastic Hemiplegia Due to Cerebral Palsy.

[Purpose] The purpose of the present study was to examine the effects of task-oriented approach on motor function of the affected arm in children with spastic hemiplegia due to cerebral palsy. [Subjects] Twelve children were recruited by convenience sampling from 2 local rehabilitation centers. The present study utilized a one-group pretest-posttest design. All of children received task-oriented training for 6 weeks (40 min/day, 5 days/week) and also underwent regular occupational therapy. Three clinical tests, Box and Block Test (BBT), Manual Ability Measure (MAM-16), and Wee Functional Independence Measure (WeeFIM) were performed 1 day before and after training to evaluate the effects of the training. [Results] Compared with the pretest scores, there was a significant increase in the BBT, MAM-16, and WeeFIM scores of the children after the 6-week practice period. [Conclusion] The results of this study suggest that a task-oriented approach to treatment of the affected arm improves functional activities, such as manual dexterity and fine motor performance, as well as basic daily activities of patients with spastic hemiplegia due to cerebral palsy.
