Clinical Trial Summary

Background: Cerebral palsy (CP) is a neurodevelopmental disorder caused by damage of the developing brain and marked by impairments such as increased muscle tone. Physical therapy (PT) is an important element for spasticity management include some modalities as transcutaneous electrical nerve stimulation (TENS).

Purpose: To determine the effect of TENS on inhibition of upper limb spasticity in adult patients with spastic cerebral palsy.

Methods: Twenty-four adult spastic CP patients aged from 18 to 45 years old with grade 2 to 3 spasticity according to Modified Ashworth Scale will be randomly assigned into two equal groups: TENS group and conventional therapy group. Both groups will receive conventional therapy, while TENS group in addition will receive TENS over elbow flexors with parameter setup of (pulse frequency= 100 Hz, pulse duration= 250 μs, time=30 mints) 3 sessions per week for successive 4 weeks.

Outcome measures: Modified Ashworth scale for the spasticity and digital goniometer for elbow joint range of motion, Barthel index scale for upper limb activity of daily living. Follow-up measures will be calculated three times (preintervention, post 2 weeks, and post 4 weeks).

Eligibility

Inclusion Criteria:

• Male and female patients aged from 18 to 45 years old

• Diagnosed with spastic CP (upper limb is affected)

• Elbow flexor muscles spasticity grade 2 to 3 according to Modified Ashworth Scale

• Good cognition (patient able to follow the instruction)

Exclusion Criteria:

• Muscle Spasticity
• Paralysis

Intervention

Device:
• Transcutaneous Electrical Nerve Stimulation (TENS)
Put the patient in comfort position as long sitting on bed with a supported back and a pillow under the forearm, clean the skin by alcohol swab, setup the parameter, put a gel on electrodes then placed the negative electrode (black wire) over biceps belly and positive electrode (red wire) 3 cm distally from negative electrode , turn on TENS device . With increase the intensity gradually until patient feel a tingling sensation (no muscle contraction) and every 10 minutes ask patient about the feeling until complete 30 minutes.

Other:
• Conventional physiotherapy treatment
Application of a hot pack for 20 minutes to enhance muscle flexibility and get overall spastic muscle relaxation. Anti-spastic muscles (elbow extensors) facilitation: tapping followed by movements (three sets of 15 repetitions per session). Hand weight-bearing with bodyweight (two 5-minute per session). Passive stretching of tight muscles (elbow flexors) is used (this must be a slow and gradual stretch for 20 seconds, followed by 20 seconds of rest, five times per session). Upper-limb active exercises should be done gradually. include (finger flexion and extension exercises, elbow and shoulder (three sets of 20 reps for each session).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Modified Ashworth Scale (MAS) to assess the muscle spasticity changes	The modified Ashworth scale is the most widely used clinical instrument for determining muscle tone changes. In this study will measure the elbow flexor spasticity by 3 examiners (3 minutes rest in between), then will calculate the average. MAS grades of spasticity are as follows: 0 = normal muscle tone; 1= slight increase in muscle tone, manifested by catch and release or by minimal resistance at the end; 1+ = slight increase in muscle tone, manifested by a catch, followed by minimal resistance throughout; 2= more marked increase in muscle tone, but limb easily flexed; 3= considerable increase in muscle tone, passive movement difficult; and 4 = limb rigid in flexion or extension. According to inclusion criteria, patients with grades 2 or 3 will be enrolled , then after intervention may be this grade will be deceased ( spasticity decreased ).	Pre intervention ( at baseline) , post 2 weeks and post 4 weeks
Primary	Digital goniometer to assess the elbow range of motion changes	Digital goniometer is a valid tool for assessing joint range of motion. The digital goniometer has adequate concurrent criterion-related validity and comparable inter- and intra-rater reliability to the Universal goniometer. Three examiners will measure elbow joint range of motion (from full flexion to full extension), ( passively) 3 minutes rest in between.	Pre intervention( at baseline), post 2 weeks and post 4 weeks
Secondary	Barthel Index to assess the activity of daily living changes	The Barthel is a quick and accurate, reliable assessment of mobility and activity of daily living , that works in both skillful and unskilled hands. In this study, the investigators will choose the items related to upper limb function (feeding, bathing, grooming, dressing and toilet use) with total score 40 which indicating highest independence and 0 indicating highest dependence .	Pre intervention ( at baseline) , post 2 weeks and post 4 weeks
