“…The proposed estimation methods would not be as accurate as the comprehensive gait analysis using the 3-D musculoskeletal model, which has allowed researchers to simulate the roles and the capacities of the lower limb muscles in individuals with CP [27]–[30]. The estimation gains might not hold across non-weight bearing tasks and weight bearing tasks.…”

Individuals with cerebral palsy have neurological deficits that may interfere with motor function and lead to abnormal walking patterns. It is important to know the joint moment generated by the patient’s muscles during walking in order to assist the suboptimal gait patterns. In this paper, we describe a practical strategy for estimating the internal moment of a knee joint from surface electromyography (sEMG) and knee joint angle measurements. This strategy requires only isokinetic knee flexion and extension tests to obtain a relationship between the sEMG and the knee internal moment, and it does not necessitate comprehensive laboratory calibration, which typically requires a 3-D motion capture system and ground reaction force plates. Four estimation models were considered based on different assumptions about the functions of the relevant muscles during the isokinetic tests and the stance phase of walking. The performance of the four models was evaluated by comparing the estimated moments with the gold standard internal moment calculated from inverse dynamics. The results indicate that an optimal estimation model can be chosen based on the degree of cocontraction. The estimation error of the chosen model is acceptable (normalized root-mean-squared error: 0.15–0.29, R: 0.71–0.93) compared to previous studies (Doorenbosch and Harlaar, 2003; Doorenbosch and Harlaar, 2004; Doorenbosch, Joosten, and Harlaar, 2005), and this strategy provides a simple and effective solution for estimating knee joint moment from sEMG.

“…Standard gait analysis methods using joint kinematics and sEMG have been used to estimate the joint moment of the lower limb in individuals with TD [23]–[26] and CP [27]–[30]. Delp et al analyzed joint moment and muscle contributions during TD [25] and CP [28]–[30] gait cycles using a 3-D musculoskeletal model.…”

“…38,43 A 'limited positive (+)' evidence level was given for its validity testing with the Berg Balance Scale, 45 and for predicting knee flexion during initial contact during stance phase of gait. [39][40][41] Therefore, their level of evidence was rated as 'conflicting (AE)'. Two studies found significant correlations and one did not.…”

“…The study of Manikowska et al compared, using EMG, Gillette's knee flexion SMC scores in patients with CP versus participants who were neurologically intact. 35,36 Two kinematic papers were already evaluated in relation to the SCALE's construct validity (see previous paragraph), 39,40 but we decided to list them under this section as well. 30 Seven papers investigated construct validity of SVMC using laboratory-based measurement tools, including lower limb kinematics, 32,34,39,40 EMG, 33 and torque steadiness.…”
