“…The amount of activity is presented as counts. Ratios (activity of impaired arm [AIA]/activity of nonimpaired arm [ANIA]) were calculated by dividing the activity counts of the affected upper limb (AIA) by the activity counts of the unaffected side (ANIA), which is in analogy with other studies [4][5][6]9]. An important reason to calculate the ratio variable is to avoid the influence of unintentional movements.…”

Abstract-Few studies have investigated how well early activity measurements by accelerometers predict recovery after stroke. First, we assessed the predictive value of accelerometer-based measurements of upper-limb activity in patients with acute stroke with a hemiplegic arm. Second, we established the difference in arm activity between hospitalized stroke and nonstroke patients. In total, 129 patients with acute stroke and 19 controls participated. Activity of the upper limbs was monitored for 48 h, and these data were used to determine the predictive value of the activity variables compared with the modified Rankin Scale (mRS), which was assessed at 3 mo poststroke onset. The sensitivity and specificity in relation to the mRS were 0.80 and 0.77, respectively, for the activity of impaired arm (AIA) and 0.85 and 0.75, respectively, for the ratio variable calculated by dividing the AIA by the activity of the nonimpaired arm. The corresponding cutoff values were 597,546 counts for AIA and 0.33 for the ratio. The predictive value of AIA combined with age was 85% to the disability status defined as an mRS score of 2 or less.

Children with hemiplegic cerebral palsy (CP) have impairments in bimanual coordination above and beyond their unilateral impairments. Recently we developed hand‐arm bimanual intensive therapy (HABIT), using the principles of motor learning, and neuroplasticity, to address these bimanual impairments. A single‐blinded randomized control study of HABIT was performed to examine its efficacy in children with hemiplegic CP with mild to moderate hand involvement. Twenty children (age range 3y 6mo‐15y 6mo) were randomized to either an intervention (n=10: seven males, three females; mean age 8y 7mo, SD 4y) or a delayed treatment control group (n=10: seven males, three females; mean age 6y 10mo, SD 2y 4mo). Children were engaged in play and functional activities that provided structured bimanual practice 6 hours per day for 10 days. Each child was evaluated immediately before and after the intervention, and again at 1‐month post‐intervention. Children in the intervention group demonstrated improved scores on the Assisting Hand Assessment, increased involved extremity use measured using accelerometry and a caregiver survey, bimanual items of the Bruininks–Oseretsky Test of Motor Proficiency, and the simultaneity of completing a draw‐opening task with two hands (p<0.05 in all cases). The results suggest that for this carefully selected subgroup of children with hemiplegic CP, HABIT appears to be efficacious in improving bimanual hand use.

Abstract-The purpose of this study was using an accelerometer to access the kinematics of reach-to-grasp movements in subjects with hemiparesis. Eight subjects (59.4 ± 6.9 years old) with chronic hemiparesis (50.9 ± 25.8 months post-stroke) participated in this study. Kinematic assessment was performed using a triaxial accelerometer (EMG Systems, Brazil) attached to the subjects' forearm. Ten reach-to-grasp movements of grabbing a 500ml-size bottle were performed by the subjects with the paretic and the non-paretic upper limbs (ULs). The following spacetemporal variables were calculated and used to compare the paretic and non-paretic ULs: movement time (MT), time to reach the peak velocity, absolute and relative (TPV and TPV%MT), relative deceleration duration (DEC%MT), time to peak acceleration (TPA) and peak hand acceleration (PA). Movements were slower in the paretic UL with increased MT, TPA and DEC. The accelerometer allowed to identify of changes in reaching-to-grasp movements of subjects with hemiparesis. When complex systems are not available, accelerometers can be an alternative to measure UL movements. Keywords: kinematic, movement, upper limb, hemiparesisResumo-"Usando um acelerômetro para analisar o movimento de alcance e e preensão após o AVE." O objetivo deste estudo foi usar um acelerometro para avaliar a cinemática do movimento de alcance e preensão de indivíduos com hemiparesia. Participaram deste estudo oito indivíduos (59,4 ± 6,9 anos) com hemiparesia crônica (50,9 ± 25,8 meses pós-AVE). A avaliação cinemática foi realizada através de acelerômetro triaxial (EMG Systems do Brasil) fixado no antebraço. Os indivíduos realizaram 10 movimentos de alcançar uma garrafa de 500 ml pelo membro superior (MS) parético e não parético. As seguintes variáveis espaço-temporais foram calculadas e utilizadas para comparar o MS parético e não parético: tempo de movimento (TM), tempo para alcançar o pico de velocidade, absoluto e relativo (TPV e TPV%TM), duração relativa da desaceleração(DEC%TM), tempo para alcançar o pico de aceleração (TPA) e pico de aceleração da mão (PA). Os movimentos foram mais lentos no MS parético com maiores TM, TPA e DEC. A utilização do acelerômetro permitiu identificar alterações no movimento de alcance em indivíduos com hemiparesia. Quando sistemas mais compexos não são disponiveis, acelerometros podem ser uma alternativa para medir o movimento do MS.
