Kinematics and paraspinal muscle activation patterns during walking differ between patients with lumbar spinal stenosis and controls

The Application of Surface Electromyography Technology in Evaluating Paraspinal Muscle Function

“…Kääriäinen [114] 30 During two years of follow-up after decompressive surgery, muscle activation profiles tended to further deteriorate. Nüesch [112] 39 During midstance, higher activation of multifidus and erector spinae showed in the patients with LSS compared with the healthy controls.…”

Classification of inertial sensor‐based gait patterns of orthopaedic conditions using machine learning: A pilot study

“…These projects focused on patients scheduled for surgery for orthopaedic conditions of specific joints or skeletal regions including KOA, HOA, LSS and CSS. 13,15,29 Only in case of CSS, patients that were treated conservatively were also included in the original study. All previous projects and the further use of these data were approved by the Ethikkommision Nordwestschweiz (EKNZ 2022-01511), and all participants provided signed informed consent.…”

“…For instance, patients walk significantly slower than healthy controls, [8][9][10][11] patients with hip osteoarthritis (HOA) have a smaller range of motion in the hip than patients with lumbar spinal stenosis (LSS), 12 and patients with knee osteoarthritis (KOA) have less knee flexion during midstance, terminal stance and pre-swing as well as greater hip extension during late swing than patients with HOA. 13 Moreover, differences in the sagittal range of motion at the hip, knee, and ankle joint during walking were found between healthy controls and patients with cervical spinal stenosis (CSS). 10,14 For patients with LSS, significant differences in spatiotemporal parameters, such as a longer stance phase and longer stride duration, a greater gait asymmetry and higher deviations in the joint angles, such as less hip extension and greater ankle dorsiflexion during midstance, compared to healthy subjects were highlighted.…”

“…10,14 For patients with LSS, significant differences in spatiotemporal parameters, such as a longer stance phase and longer stride duration, a greater gait asymmetry and higher deviations in the joint angles, such as less hip extension and greater ankle dorsiflexion during midstance, compared to healthy subjects were highlighted. 13,15 There is also evidence that OA in one joint, for instance the knee, also results in secondary gait changes in adjacent and contralateral joints of the lower extremity. Compensatory gait mechanics in patients with unilateral KOA, HOA, or ankle OA not only include the affected joint but also the other joints of the lower extremity, which not only differ from gait patterns in asymptomatic controls but also between patients with OA of different joints.…”

Muscle activity and rehabilitation in spinal stenosis (MARSS) after conservative therapy and surgical decompression with or without fusion: Protocol for a partially randomized patient preference trial on rehabilitation timing

“…However, these can provide concrete evidence of muscular function and coordination and thus detect dysfunction or dyscoordination. A correlational study examining gait and muscle activation characteristics could demonstrate increased paraspinal and gluteal muscle activity in patients with LSS [ 14 ]. After decompression surgery, patients showed decreased paraspinal and increased gluteal muscle activation [ 15 ].…”
