Procedure and dosage for various groups

Groups	Intervention
Group A	Conventional treatment that included hot pack, isometric quadriceps exercises, high sitting knee extension, and straight leg raise, 10 repetitions once a day, three times a week for six weeks.
Group B	Forward and backward stepping, sideways exercises (3 sets of 10 repetitions), hip muscle strengthening, standing isometric abduction (2 sets of 5 repetitions), knee muscle strengthening (3 sets of 10 repetitions), step-ups & down (3 sets of 10 repetitions), balance exercise for two minutes three times a week for six weeks [26].
Group C	NMES with the following parameters: pulsed current, asymmetrical, frequency 50 Hz, pulse duration 250 μs, contraction time 10 s, rest time 30 s every 20 minutes; current intensity maximum tolerated by each patient for thrice a week for 6 weeks [15].
Group D	Combination of NEMEX, NMES and conventional treatment three times week for six weeks.
