“…Muscle strength and ROM: The assessment of muscle strength was performed using a manual dynamometer (SP Tech, Medeor MedTech, Santa Catarina, Brazil), with a maximum capacity of 90.72 kgf (200 lbf) and reliable for use in this population. 22 Three isometric contractions lasting 15 seconds were performed for trunk extension, knee flexion and extension, internal and external rotation of the hip and and plantar flexion and dorsiflexion of the ankle (Supplemental Material).…”

Introduction: Functional incapacity caused by physical alterations leads to significant limitations in daily activities and has a major impact on the return of people with disabilities to the social space and the workplace. This calls for an evaluation of the long-term influence of the use of a device specially developed for orthostatic posture on the physiological, biomechanical and functional parameters of amputees and spinal cord patients. Objective: The objective was evaluate the effect of postural support device use on function, pain, and biomechanical and cardiologic parameters in spinal cord injury and amputees patients compared to a control group. Methods: The orthostatic device was used by the participants for a period of ten consecutive days, for three cycles of 50 minutes each day, and a 15-day follow-up. Participants were positioned and stabilized using adjustable straps on the shoulders, trunk, and hips. The primary outcome was brief pain inventory. Fifteen participants were included the control group, 15 in the amputee group, and 15 in the spinal cord group. Results: Our results demonstrate that the use of the device allows the orthostatic position of amputees and spinal cord patients evaluated for ten days, leading to improved functionality and pain in the spinal cord and amputee groups compared to the control group. In addition, no changes were observed for secondary outcomes, indicating that the use of the device did not cause harm interference to patients. Conclusion: The long-term use of the orthostatic device is beneficial for improving functionality, reduce pain in amputees and spinal cord injury patients.

“…The assessment of isometric knee extension muscle strength using an objectively quantifiable handheld dynamometer (HHD) is highly applicable to a wide range of age groups, from 3 years to over 65 years, as well as to patients with illnesses 1 , 2 , 3 , 4 ) . Two methods are used to measure muscle strength using HHD, handheld, or belt-stabilized sensors.…”

[Purpose] To determine the intra-rater and inter-devices reliability of isometric knee-extensor muscle-strength-measurement. [Participants and Methods] The participants were 77 university students (50 males; 27 females) who underwent isometric knee-extension muscle-strength measurement twice with a belt-stabilized handheld dynamometer and isokinetic dynamometer. The intra-rater and inter-devices reliability was ascertained from measurements that were performed with the participant seated on the edge of the bed, the toes of the contralateral nonexamined side off the floor, and the trunk supported by the upper limb. [Results] In the overall, male, and female cohorts, the 95% confidence intervals of intra-rater reliabilities (1,1) in the belt-stabilized handheld and isokinetic dynamometers were 0.96–0.98, 0.92–0.97, and 0.81–0.96, 0.82–0.92, 0.73–0.90, and 0.78–0.95, respectively, and the inter-device 95% confidence intervals were 0.52–0.77, 0.28–0.69, and −0.03 to 0.63, respectively. Compared to the belt-stabilized handheld dynamometer group, the isokinetic dynamometer group had higher knee-extension muscle strength. [Conclusion] The intra-rater reliability was rated good-to-excellent and moderate-to-excellent for the belt-stabilized handheld and isokinetic dynamometers, respectively. The inter-devices reliability was poor, and isometric knee-extension muscle strength in the isokinetic dynamometer group was higher than that in the belt-stabilized handheld dynamometer group.
