“…Trunk flexion may have been reduced by the higher initial momentum caused by the increased strength in lower-limb extensor muscles. As a result, joint coordination would improve in sit-to-stand exercises, as proposed by Fujimoto and Chou [ 30 ] and Bowser et al [ 31 ]. Therefore, the CTP helped MS subjects improve their performance in sit-to-stand tests as a result of the improvement achieved in dynamic strength.…”

This study investigated the effects of a 24-week combined training program (CTP) based on strength exercises and cognitive–motor tasks performed concurrently in participants with multiple sclerosis. A randomized, controlled intervention study was carried out. In total, 31 subjects with a confirmed diagnosis of multiple sclerosis (14 men and 17 women) were stratified and randomized into an intervention group (17 subjects) and a control group (14 subjects). The intervention group completed three weekly training sessions for 24 weeks, while the control group pursued their normal daily activities. In this program, cognitive–motor tasks were completed at once (dual tasking). A 3D photogrammetry connected to a selective attention system designed for dual tasking while walking was used. Ground reaction forces were measured using two force plates, one for sit-to-stand testing, while the other was used for static force measurement. Postural equilibrium was examined using a stabilometric plate based for Romberg test assessment. The 24-week training program for multiple sclerosis patients improved their static peak force by 11% (p < 0 .05), their rate of force development by 36% (p < 0.05), and their balance (p < 0.05). Performance in daily activities such as walking or sitting-to-standing improved significantly in multiple sclerosis participants. CTP training was effective in reducing the dual-task costs of step length (48%) and walking velocity (54%), as compared to a matched control group.

“…The magnitude of coactivation was highest in the patients with the slowest gait, the greatest motor impairment and the most instability. 3 Bowser et al 2015, USA [ 47 ] To compare sit-to-stand biomechanics among three groups: people with multiple sclerosis who exhibit leg weakness, people with multiple sclerosis who have comparable strength to controls, and healthy controls. Cross-sectional design; n = 21 PwMS divided in two groups: Leg weakness group n = 10, mean age 49.2 Comparable strength group n = 11, mean age 39.8 Lower extremity muscle strength Persons with multiple sclerosis exhibiting leg weakness displayed decreased leg strength, greater trunk flexion, faster trunk flexion velocity and decreased knee extensor power compared to the other two groups, and slower rise times compared to controls.…”

“…Changes lower extremity biomechanics and muscle strength caused lower extremity problems which were affecting gait in many ways [ 48 , 54 , 56 ]. The lower extremity problems caused walking difficulties which were seen in the length of the step or the walking speed [ 44 , 47 , 48 , 54 , 73 ]. Walking and mobility problems and a limited range of motion in the lower limb joints were the most bothersome symptoms in patients with MS [ 44 ].…”

“…This kind of information could be used as the basis for future interventions and technological innovations. [46,47,51,56,62,82] Impaired balance [48,50,51,67] Walking dysfunction [44,54,59,66,67,73,78,79,82,84] Decreased pressure sensation [50] Decreased vibration sensation [50,60] Sudomotor dysfunction [60] Oedema [80] Pes cavus [75] Claw toes [75] Spasticity [68,81] One important aspect of lower extremity health is foot self-care, but there is limited evidence of how patients with MS manage this. Therefore, it is important to identify potential gaps in foot care knowledge and habits among patients with MS, which could be done by using, for example, information technology for communication.…”

Background: Multiple sclerosis (MS) often affects ambulation and the function of the lower limbs. However, little is known about how much research has been conducted on lower extremity health in patients with MS. Objective: To analyse empirical studies and their evidence on lower extremity health in patients with MS, in order to identify the need for future studies in key areas. Methods: A systematic scoping review was conducted. A literature search of Medline (PubMed), CINAHL (EBSCO) and the Cochrane Library databases was performed. The search covered the period up to 15 January 2020 from the earliest records available. This led to the inclusion of 42 empirical articles. The data were analysed using content analysis and quantification techniques. Results: The research on lower extremity health focused primarily on two main areas: gait and lower extremity muscle strength. Lower extremity health was assessed using a variety of methods, most of which consisted of objective physical tests and gait analysis. Patients with MS had many problems with the health of their lower extremities, which manifested in walking difficulties, balance problems, muscle weaknesses and spasticity. In the feet, pes cavus, claw toes, oedema and altered foot sensation were common. Conclusions: MS affects lower limb and foot health, and these problems can affect patients' daily lives. However, the extent of these problems is poorly understood, partly due to the dearth of research on lower limb and foot health. Therefore, further research is warranted in order to better understand the impact of MS on foot and lower limb health in everyday life.

“…16,17 The biomechanics of the sit-to-stand and sit-to-walk movement, in people with disabilities, has been previously reported. [18][19][20][21] The identification of movement strategies, or the study of their effects has been achieved via questionnaires, video observation and motion analysis. [22][23][24][25][26] Pushing through the armrest, pushing through the knees, scooting forward, leaning forward, thorax flexion and obliquity, feet backward, and no arms used have all been identified as categories of movement strategy.…”
