简要总结
This study examined the effect of reciprocal electrical stimulation (RES) across elbow flexors and extensors on the reaction of degeneration percentage and motor function in Erbs palsy infants.
Forty infants with Erb's palsy aged between 2-5 months were randomly allocated to one of two equal groups: the control group (A) received standard physical therapy, the study group (B) received traditional physical therapy plus a 15-minute RES through elbow flexors and extensors. For three months, interventions were carried out three times each week. The percentage of degeneration and motor function reaction were assessed pre-and post-treatment using electromyography and Toronto active motion scale, respectively.

主要结局
Percentage of degeneration
时间窗: 2 months
Surface electrodes were used in a computerized electromyographic device (Neuro screen plus four channel-version, TOENNES 97204 Hochberg, Germany) to calculate the percentage of degeneration of the biceps and triceps brachii muscles. A 1 Hz frequency and 5 ms time basis were used to create a rectangular pulse. The strength of the stimulating current was gradually raised until there was no further rise in the amplitude of the diphasic myogenic compound action potential. A 10% increase in current was given to assure supramaximal stimulation. The level of stimulation ranges from 15 to 40 mA. The Neuro screen plus system's software was used to calculate the peak-to-peak amplitude. The following equation was used to compute the percentages of degeneration: RD= 100{Amplitude of evoked response(in µv) affected side/Amplitude of evoked response(in µv)normal side x 100}
Toronto active motion scale (TAMS)
时间窗: 2 months
The motor recovery was assessed using the Toronto Active Motion Scale (TAMS). For this study, scores for elbow flexion and extension were recorded. It consists of 15 movements of upper limb joints with an eight-point scale measuring the strength of these movements, first by measuring the range of motion at each joint with gravity eliminated, and then measuring the range of motion against gravity. The scoring of the TAMS is defined as follows: Observation Gravity elimination Muscle grade No muscle contraction 0 Contraction, no movement 1 Motion \< range 2 Motion \> range 3 Full range of movement 4 Against gravity Motion \< range 5 Motion \> range 6 Full range of movement 7
