participants in this arm receive PNF without electrical stimulation to reduce pain and functional disability in patients with chronic lumbar radiculopathy

Group A receive PNF including combination of isotonic and rhythmic stabilization on trunk with electrical stimulation Participants perform three sets10 repetitions at maximal resistance The resting interval of 30 seconds and 60 seconds will be provided after the completion of 10 repetitions for each pattern and between sets respectively.

In total all PNF exercise will be held for 30 to 45 minutes. 'BURST' TENS (acupuncture-like TENS), characterized by discontinuous stimulation at low frequencies (1-4 Hz), with wave durations of 100-400 ms and high intensities, inducing weak muscle twitches for 10 minutes.

The pain numeric rating scale is a segmented numeric version of visual analog scale in which a respondent selects a whole number 0 to 10 that reflects the intensity of pain. The 11 point numeric scale ranges from 0 representing no pain and 10 representing extreme pain. Higher scores indicating greater pain intensity. e.g. as bad as you can imagine or worst pain. NPRS takes less than 1 minute to complete and easy to administer and score.

MODI also known as the Oswestry Low Back Pain Disability Questionnaire, as a very crucial instrument to assess a patient's functional disability over the long term. MODI is a patient completed questionnaire included 10 sections of questions. This tool is effective for persistent severe disability. The MODI domains are the following: pain intensity, personal care, lifting, walking, sitting, standing, sleeping, social life, travelling and employment/home making. Each section has six statements that are scored from 0 means minimum degree of difficulties in that activity to 5 means maximum degree of difficulty.
