![]() ![]() Participants demonstrated dramatic improvement of the sEMG activity during game play. Participants completed a mean of 8.8 hours of NGT over 5-6 weeks. Secondary outcomes included changes in co-contraction, range of motion, segmental alignment, and spontaneous upper extremity function following intervention. specificity (changes in sEMG activity during game play). Primary outcomes of NGT included feasibility (hours of play) and. NGT uses surface electromyographic (sEMG) signals routed through motivating computer games to improve motor control. This case series examines the feasibility, specificity, and preliminary effectiveness of NeuroGame Therapy (NGT) for improving wrist control in four children with cerebral palsy (CP). Assessment of blood pooling could be used to study arm pain of Useful to design and develop a biofeedback controller for anti G-suit ofġ. Results obtained forĪssessment of blood pooling in the forearm clearly establishes that theĮIP provides assessment of blood pooling noninvasively with noĭiscomfort to the body. OFP techniques resulted correlation factor of 0.99. Maximum blood pooling found as approximately 10 ml in the forearmĬorresponding to maximum cuff pressure of 100 mmHg. Plotted for fi ve sets of experimental data of blood pooling assessed byĮIP and OFP techniques for applied pressures from 0 to 100 mm Hg. For OFP measurements, capillary fi tted on the plastic containerĭirectly indicated blood pooling of forearm. Blood pooling wasĬalculated from base and lowered values of forearm electrical impedance.īlood pooling assessed by EIP was compared by oil fi lled Plethysmograph Recorded without infl ation and with infl ations of cuff. The electrical impedance of the forearm was then The EIP was then connected to the electrodes viaĬonnecting leads. TwoĪluminum foil current electrodes (I1, I2) and two aluminum foil voltageĮlectrodes (E1, E2) were made and placed on the wrist and above elbow Were observed on digital display of Impedance Plethysmograph. The electrical impedance changes from base value Polar electrode system was used to drive a constant current of 3mA atĢ0 KHz into forearm. Electrical Impedance Plethysmography (EIP) with tetra ![]() ![]() When the cuff was infl ated to pressures beyond venous pressure butīelow arterial pressure, blood pooling in the lower arm below the cuff Physiologically blood pooling has been induced in the forearm by placingĪ blood pressure cuff around the upper arm of human volunteers. Pilot’s ability to function eff ectively during high G maneuvers. Onset ofĪrm pain terminates high G centrifuge test runs and reduces aircraft Gravity (G) Suit is worn along with positive pressure breathing. A number of studies reveal thatīlood pooling induces arm pain especially when Extended Coverage Anti Pooling in the body of the aircraft pilot.
