“…No such difference between sides was reported when applying the prediction algorithm on healthy walking patterns ( Fluit et al, 2014 ). It is possible that this side-to-side difference results from the non-optimality of the pathological locomotor patterns, as children with unilateral CP rely more on their unaffected limb than on their affected one, especially during double support phases, potentially due to a lack of strength and confidence in their affected limb ( Kim et al, 2015 ).…”

IntroductionGait analysis is increasingly used to support clinical decision-making regarding diagnosis and treatment planning for movement disorders. As a key part of gait analysis, inverse dynamics can be applied to estimate internal loading conditions during movement, which is essential for understanding pathological gait patterns. The inverse dynamics calculation uses external kinetic information, normally collected using force plates. However, collection of external ground reaction forces (GRFs) and moments (GRMs) can be challenging, especially in subjects with movement disorders. In recent years, a musculoskeletal modeling-based approach has been developed to predict external kinetics from kinematic data, but its performance has not yet been evaluated for altered locomotor patterns such as toe-walking. Therefore, the goal of this study was to investigate how well this prediction method performs for gait in children with cerebral palsy.MethodsThe method was applied to 25 subjects with various forms of hemiplegic spastic locomotor patterns. Predicted GRFs and GRMs, in addition to associated joint kinetics derived using inverse dynamics, were statistically compared against those based on force plate measurements.ResultsThe results showed that the performance of the predictive method was similar for the affected and unaffected limbs, with Pearson correlation coefficients between predicted and measured GRFs of 0.71–0.96, similar to those previously reported for healthy adults, despite the motor pathology and the inclusion of toes-walkers within our cohort. However, errors were amplified when calculating the resulting joint moments to an extent that could influence clinical interpretation.ConclusionTo conclude, the musculoskeletal modeling-based approach for estimating external kinetics is promising for pathological gait, offering the possibility of estimating GRFs and GRMs without the need for force plate data. However, further development is needed before implementation within clinical settings becomes possible.

Different temporal weight-bearing tendencies of persons with right and left hemiplegia while sitting in a wheelchair

The tendency of persons with hemiplegia to sit for prolonged periods can cause excessive interface pressure (IP) on their buttocks. Due to the different neuromusculoskeletal conditions, different buttock IP relief methods are required for persons with left hemiplegia (LH) and right hemiplegia (RH). Therefore, this study investigates temporal characteristics of IP on the right and left buttocks for RH, LH, and able-bodied individuals (AB) sitting in a wheelchair for 30 min. Thirty-five males participated in the study: 13 LH, 12 RH, and 10 AB. In the initial adjustment phase, the participants maintained an erect sitting posture for 7 min (2 min for posture and 5 min for creep adjustments). After the adjustments, experiments were conducted for 30 min to measure the IP. In the experiments, significant right-sided asymmetries of the mean IP were found for each group (P < 0.05). The right buttocks of LH exhibited significantly more right-sided asymmetry of the mean IP than that of AB (p < 0.01). Moreover, the right buttocks of RH exhibited insignificant asymmetry of the mean IP compared to that of AB (p >0.21). The peak IPs of RH and LH were significantly higher than those of AB (p <0.05), and temporal changes of the mean and peak IP of hemiplegia were significant (p <0.05) and not significant (p >0.05), respectively. The RH exhibited affected-side weight-bearing based on the mean IP. In contrast, the LH relieved the mean IP on the affected-side buttock. Due to the right-sided asymmetric mean and high peak IP, hemiplegia in acute and recovery stages using wheelchairs can cause ulceration. Therefore, different rehabilitation approaches are required for the RH and LH to reduce the peak IP and avoid an uneven distribution of the mean IP.

Mitigating Gait Decline in a Woman With Parkinson’s Disease: A Case Report

Levodopa therapy is the standard pharmacological treatment for Parkinson’s disease (PD). However, after an initial period of significant benefit, the effects of levodopa begin to wear off. This results in a reduction in the effect duration and the development of motor complications. We describe the case of a 69-year-old woman presented with a 3-year history of lower back pain and progressive left leg weakness. One year prior to referral for neurological assessment, the patient first noted progressive leg weakness and insufficient strength to rise from a chair. The diagnosis of PD was made after excluding potential neurological disorders. The patient was initially started on oral levodopa, which improved her motor symptoms considerably during the first year. However, dose adjustment and combined pharmacological strategies failed to sufficiently control motor symptoms during the subsequent year. The patient experienced declines in gait ability, clumsiness in the left limbs, and difficulty in performing housework. The patient then sought chiropractic attention. Gait rehabilitation was the major goal in the treatment program for this patient, with the impression of motor complications of PD. The intervention consisted of spinal manipulation, intermittent motorized traction of the lumbar segments, and gait training programs. Following 3 months of the intervention, the patient demonstrated increased muscle strength and improved gait characteristics, as depicted by a gait cyclogram and vertical ground reaction force graphing. The current report illustrates that a multicomponent chiropractic approach may be used as an additional measure to mitigate gait decline in PD patients.
