“…Excessive cocontraction and abnormal muscle recruitment may limit the movement in the central nervous diseases. Studies have indicated higher cocontraction ratio of the affected limb in stroke [ 7 ] and cerebral palsy [ 8 ]. CCFES also favored decreased cocontraction of flexor carpi radialis, without significant difference with NMES.…”

“…The RMS of paretic extensor carpi radialis was standardized by calculating sEMG signal ratio in percentage, a ratio of RMS of the paretic side/the nonparetic side. Cocontraction ratio (CCR) of paretic flexor carpi radialis was calculated by the ratio of RMS of flexor carpi radialis/(RMS of flexor carpi radialis + RMS of extensor carpi radialis) [ 8 ]. The smaller CCR of paretic wrist flexors indicates the better motor control of voluntary wrist extension…”

Purpose. To compare the effectiveness of contralaterally controlled functional electrical stimulation (CCFES) versus neuromuscular electrical stimulation (NMES) on motor recovery of the upper limb in subacute stroke patients. Materials and Methods. Fifty patients within six months poststroke were randomly assigned to the CCFES group ( n = 25 ) and the NMES group ( n = 25 ). Both groups underwent routine rehabilitation plus 20-minute stimulation on wrist extensors per day, five days a week, for 3 weeks. Fugl-Meyer Assessment of upper extremity (FMA-UE), action research arm test (ARAT), Barthel Index (BI), and surface electromyography (sEMG) were assessed at baseline and end of intervention. Results. After a 3-week intervention, FMA-UE and BI increased in both groups ( p < 0.05 ). ARAT increased significantly only in the CCFES group ( p < 0.05 ). The changes of FMA-UE, ARAT, and BI in the CCFES group were not greater than those in the NMES group. The improvement in sEMG response of extensor carpi radialis by CCFES was greater than that by NMES ( p = 0.026 ). The cocontraction ratio (CCR) of flexor carpi radialis did not decrease in both groups. Conclusions. CCFES improved upper limb motor function, but did not show better treatment effect than NMES. CCFES significantly enhanced the sEMG response of paretic extensor carpi radialis compared with NMES, but did not decrease the cocontraction of antagonist.

“…Altered muscle tone and muscle coactivation is a typical feature in individuals with hypertonia, especially in antigravity muscles ( 40 ). This impairment could cause worse performance, decreasing players’ movement efficiency ( 41 ), reducing movements’ velocity ( 42 ) and hindering continuous elbow flexion–extension movements. On the other hand, players with severe dyskinetic or ataxic profiles may display uncontrollable muscle contractions, tending to activate the antagonist muscles before the agonist ( 43 ).…”

Manual Dexterity and Intralimb Coordination Assessment to Distinguish Different Levels of Impairment in Boccia Players with Cerebral Palsy

et al. 2017

BackgroundBoccia is a paralympic sport played by athletes with severe neurological impairments affecting all four limbs. Impaired manual dexterity (MD) and intralimb coordination (ILC) may limit individuals’ ability to perform certain activities such as grasping, releasing, or manipulating objects, which are essential tasks for daily life or to participate in para sports such as boccia. However, there are currently no specific instruments available to assess hand–arm coordination in boccia players with severe cerebral palsy (CP).PurposeTo design new sport-specific coordination tests to assess impaired MD and ILC in boccia players; afterward, quantify to what extent their coordination is impaired compared to a control group (CG) without neurological impairments.MethodsSeventy-three recreational boccia players with severe CP (BC1: age = 34.01 ± 16.43 years; BC2: age = 33.97 ± 14.29 years), and 19 healthy adults (age = 27.89 ± 7.08 years) completed the test battery. The Box and Block test (BBT) and Box and Ball test (BBLT) were used to assess MD and four tapping tests to assess upper ILC.ResultsBoth MD tests were able to discriminate between sport classes. Boccia players obtained better scores in the BBLT in comparison to the BBT, showing that the BBLT had more appropriate testing features. On the other hand, only one of the ILC tests was able to discriminate between sport classes, displaying the highest practical significance (d = −1.12). Participants with CP scored significantly worse in all the coordination tests compared to the CG.ConclusionUsing sport-specific equipment facilitated grasp function during the MD assessment. Regarding the ILC, the type of movement (continuous vs. discrete) seems to be more relevant for classification than the movement direction (vertical vs. horizontal) or the presence of a ball.
