About this trial
Stroke is one of the world's leading causes of death and disability. It can cause a variety of motor disorders, such as apraxia, sensory deficits, abnormal muscle tone, inadequate weight transfer, lack of fine motor skills, incoordination, and balance deficit. These disorders can have a significant negative impact on a person's quality of life.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Both male and female patients were included in the study.
The age range of participants was between 45 and 60 years.
Participants that were diagnosed with ischemic stroke patient.
Participants had experienced sub-acute ischemic stroke, specifically 15 days to 12 weeks post-stroke.
Disqualifiers
People who had a history of serious neurological or mental conditions that would have impeded lower limb motor recovery-aside from stroke-were not included.
Individuals with severe arthritis or joint injuries, among other illnesses that would have interfered with treatment or evaluations, were not allowed to participate.
Individuals who had significant hearing or vision impairments that would have hampered treatment or evaluations were not included.
Individuals undergoing anti-spatial therapy or other clinical trials, those with bilateral brain lesions, and those with ischemic involvement of the cerebellum or basal ganglia were not allowed to participate.

Treatments tested in this trial
Experimental Group A: Segmental vibrator only on dorsiflexor
Other interventionSegmental vibrator only on dorsiflexor: After standard physiotherapy session this group received the intervention of segmental vibration. Tibialis anterior muscle targeted for dorsiflexor. The segmental vibration of high frequency i.e 100 Hz and low amplitude (0.2-0.5mm) was applied at muscle belly for 10 min while interpersed with a 1 min break by mean of segmental vibrator.
Experimental Group B: Segmental vibrator + Electrical stimulation on dorsiflexors
Other interventionSegmental vibrator + Electrical stimulation on dorsiflexors: After standard physiotherapy session this group received the intervention of neuromuscular electrical stimulations by means of EMS. Two electrodes were used for this procedure. Tibialis anterior muscle targeted for dorsiflexor. One pad of electrode was placed on anterior of lower leg just below tibial tuberisty and other was 5cm below to it .With a 250-microsecond pulse duration, the EMS device was set up to provide a biphasic current with a symmetrical waveform at 50 Hz for 15 seconds. It was also tuned for a 3-second ramp up time and a 30-second rest period. Each respondent set the intensity to the highest level they could tolerate. Secondly, segmental vibrator was applied for focal vibrations on tibialis anterior. The segmental vibration of high frequency i.e 100 Hz and low amplitude (0.2-0.5mm) was applied at muscle belly for 10 min while interpersed with a 1 min break by mean of segmental vibrator.

Trial outcomes
Primary outcomes
1
Modified Ashworth Scale (for spasticity)
The Modified Ashworth Scale (MAS) is a revised version of the original Ashworth Scale that measures spasticity in patients with lesions to the central nervous system. MAS is an assessment that is used to measure the increase in muscle tone. MAS assigns a grade of spasticity from a 0-4 ordinal scale.

Fugl-Meyer Assessment (for lower limb function)
Fugl-Meyer Assessment (FMA) is a stroke-specific, performance-based impairment index. It is designed to assess motor functioning, balance, sensation and joint functioning in patients with post-stroke hemiplegia. The scale is comprised of five domains and there are 155 items in total: * Motor functioning (in the upper and lower extremities) * Sensory functioning (evaluates light touch on two surfaces of the arm and leg, and position sense for 8 joints) * Balance (contains 7 tests, 3 seated and 4 standing) * Joint range of motion (8 joints) * Joint pain Scale items are scored on the basis of ability to complete the item using a 3-point ordinal scale where 0=cannot perform; 1=performs partially; and 2=performs fully. The total possible scale score is 226.

10 Metre Walk Test (mobility)
The 10-Metre Walk Test is a performance measure used to assess walking speed in meters per second over a short distance. It can be employed to determine functional mobility, gait, and vestibular function. Gait speed is calculated by dividing the total distance to time

8 weeks4
Wisconsin Gait Scale (for gait)
Wisconsin Gait Scale (WGS) is an observational tool for the evaluation of gait quality in individuals after stroke with hemiplegia. It is divided into four subscales, which assess a total of fourteen spatiotemporal and kinematic parameters of gait observed during the consecutive gait phases.
