Comparison of High Intensity Laser Therapy (HILT) and Extracorporeal Shock Wave Therapy (ESWT) for the Treatment of Plantar Flexor Spasticity in Post-Stroke Patients
In Brief
A clinical study evaluating Rehabilitation Protocol, Extracorporeal Shock Wave Therapy (ESWT), and 1 other intervention for Stroke Gait Rehabilitation. Completed, enrolled 39 participants across 1 site.
Detailed Summary
Stroke is one of the leading causes of long-term disability worldwide. Spasticity (muscle spasm) is a common and disabling consequence of stroke. Lower extremity spasticity significantly compromises postural control, balance, and gait performance. Patients with spasticity demonstrate greater difficulty in standing and walking compared with non-spastic stroke survivors. Management of spasticity includes physical therapy modalities, exercise programs, orthoses, and pharmacological agents. In recent years, novel noninvasive treatment modalities including extracorporeal shock wave therapy (ESWT), and low- and high-intensity laser therapy (HILT) have been investigated for spasticity management however, robust evidence remains limited. ESWT is a treatment method applied by focusing high-pressure sound waves produced outside the body on the desired area of the body using a steel-tipped applicator. Patients can resume their daily activities immediately after a treatment session lasting between 5-20 minutes. Scientific researches have demonstrated that ESWT is a safe and effective modality for reducing upper and lower extremity spasticity after stroke. HILT is a a non-invasive, advanced therapeutic approach that utilizes high-intensity laser technology to promote healing and alleviate pain. It has been widely used in musculoskeletal disorders and generally well tolerated without significant adverse effects. Previous studies suggest that laser application to spastic muscles after stroke may reduce spasticity and pain. The present study aimed to investigate and compare the effects of ESWT and HILT applied to the calf muscles on spasticity and functional gait parameters only with clinical examination methods in patients with stroke.
Study Details
Timeline
Interventions
All participants received a standardized rehabilitation program consisting of 1-hour sessions, 5 days per week, for 3 consecutive weeks. The program included: * Range of motion and stretching exercises targeting the hamstrings, rectus femoris, and ankle plantar flexors; * Strengthening exercises for hip flexors, hip extensors, knee extensors, hamstrings, ankle plantar flexors, and trunk muscles; * Gait training, postural exercises, balance training, transfer training, and endurance exercises, all performed under the supervision of a physiotherapist
Participants in the ESWT group received ESWT once weekly for 3 consecutive weeks (total of 3 sessions), in addition to the rehabilitation program. ESWT was applied to the gastrocnemius muscle belly in the prone position using a Starz Medical Masterpuls MP100 device, with the following parameters: frequency 5 Hz, energy flux density 0.340 mJ/mm², 2000 pulses, and a 15-mm applicator.
In addition to the rehabilitation program, participants in the HILT group received HILT three times per week for 3 consecutive weeks (total of 9 sessions). Each session lasted 4 minutes. HILT was applied to the gastrocnemius muscle belly in the prone position using longitudinal movements, with an energy density of 50 J/cm² and output power of 5 W in biostimulatory mode, using a BTL-6000 High-Intensity Laser device.
