“…In a future work, the foot-stretching technique used by each physical therapist and its effectiveness for the patient should be analyzed simultaneously to establish an effective stretching method. Moreover, several previous studies developed automatic machines for ankle stretching 15 , 16 , 17 , 18 ) . Although currently, no such machine has been commercialized, the analysis of foot-stretching techniques in this study will help in their development.…”

[Purpose] Physical therapists frequently perform manual stretching of the ankle joints. Manual stretching procedures are challenging to define because they involve multidirectional joint motions and external forces. Therefore, in this paper, we propose a method for quantitatively and statistically analyzing the manual foot stretching techniques used by physical therapists. [Participants and Methods] The participants were four physical therapists, and three patients who have a spastic foot. We investigated the manual foot stretching techniques employed by the physical therapists using a three-dimensional analysis system and an instrumented brace with force sensors. Principal motion analysis was applied to the obtained data, and principal motions were determined. [Results] The first principal motion was the application of force for the dorsiflexion of the foot; second, the pushing/pulling of the heel; third, the eversion/inversion of the entire foot; and fourth, the eversion/inversion of the forefoot. Furthermore, the manual stretching techniques varied among the physical therapists, even for the same patient, and some techniques occurred only between particular pairs. [Conclusion] This study demonstrated the effectiveness of the principal motion analysis for the statistical assessment of manual stretching techniques and clarifying differences in stretching technique among physical therapists.

“…Currently, there exist numerous robotic systems focused on sensory-motor rehabilitation of patients with motor problems from a neurological disorder; for instance, MIME [ 31 ], InMotion [ 32 ], NeReBot [ 33 ], among others [ 34 , 35 , 36 ]. Since the use of robotic devices specifically designed for neurorehabilitation has shown positive effects in motor function recovery [ 37 ], some studies have included a robotic device for treating the spasticity phenomenon [ 38 ]. However, the development of robot-aided systems aiming to evaluate the degree of upper limb spasticity is reduced.…”

“…A possible explanation for this might be that the MAS is the most used scale among clinicians. The scale behaves better for upper limbs than for lower limbs, but even so, it is widely applied for measuring spasticity in the lower limb [ 38 ].…”

Spasticity is a motor disorder that causes stiffness or tightness of the muscles and can interfere with normal movement, speech, and gait. Traditionally, the spasticity assessment is carried out by clinicians using standardized procedures for objective evaluation. However, these procedures are manually performed and, thereby, they could be influenced by the clinician’s subjectivity or expertise. The automation of such traditional methods for spasticity evaluation is an interesting and emerging field in neurorehabilitation. One of the most promising approaches is the use of robot-aided systems. In this paper, a systematic review of systems focused on the assessment of upper limb (UL) spasticity using robotic technology is presented. A systematic search and review of related articles in the literature were conducted. The chosen works were analyzed according to the morphology of devices, the data acquisition systems, the outcome generation method, and the focus of intervention (assessment and/or training). Finally, a series of guidelines and challenges that must be considered when designing and implementing fully-automated robot-aided systems for the assessment of UL spasticity are summarized.

“…A previous study reported that an external output torque of approximately 13.5 Nm was required to assist dorsi exion movement from a drop foot posture [22]. Considering factors of individual differences and our application for subacute patients for full dorsi exion assistance during gait rehabilitation, the output torque of the system was set close to double, at 25 Nm.…”

A number of robotic ankle-foot orthoses with practical application for stroke patients have been developed in recent years. However, targets are mainly patients in the chronic phase. In this paper, we present development of a high-dorsiflexion assistive system aiming to support passive dorsiflexion movement in the swing phase for subacute patients in the early phase of gait rehabilitation. By applying a McKibben-type artificial muscle, output of high dorsiflexion torque with a low-weighted prototype was realized. This is expected to minimize loading burden on subacute stroke patients. An experiment on six healthy participants was conducted, and different extents of compensatory movements were applied when their dorsiflexion movements were restricted. The results of processed surface electromyography data significantly decreased when dorsiflexion movement was assisted with our system. Meanwhile, the results of spatial parameters also showed significant improvement of compensatory movement inclination with sufficient assistance. These indicate the potential of realizing assistance of passive ankle movements for patients with very low dorsiflexion abilities, which shows the potential for our future planning of practical pilot studies.
