Brief Summary

Postural stability is a complex sensorimotor process that depends on the integration of visual, vestibular, and somatosensory inputs, and its impairment increases the risk of falls and negatively affects quality of life. Prolonged sitting and low physical activity negatively influence postural stability, whereas regular physical activity has a positive chronic effect, despite some exercises causing temporary instability due to fatigue. Breaking up sitting time with light walking or active workstations may improve postural stability, and this study aims to evaluate the effects of McKenzie back extension exercises on postural stability, pain, and quality of life in individuals with mechanical back pain.

Outcome Measures

Primary Outcomes (2)

• postural stability

  postural stability will be measured by Biodex Balance System SD

  up to 6 weeks

• pain intensity

  pain intensity will be measured by VAS. A horizontal line, 100 mm in length, anchored by word descriptors at each end. The patient marks on the line the point that they feel represents their perception of their current state.

  up to 6 weeks

Secondary Outcomes (3)

• short form 36 health survey questionnaire (SF-36)

  up to 6 weeks

• Arabic sedentary behaviors questionnaire (ASBQ)

  up to 6 weeks

• lumbar lordotic curve by using Kinovea software program

  up to 6 weeks

Study Arms (2)

Mckenzie exercise

EXPERIMENTAL

this group will receive traditional physiotherapy program plus, Exercise 1 lying prone the patient adopts the prone lying position with the arms alongside the trunk and the head turns to one side. Exercise 2 lying prone in extension places the elbows under the shoulders and raises the top half of his body so that he comes to lean on elbows and forearms while pelvis and thighs remain on the couch. .Exercise 3 extension in lying the patient, already lying prone, places the hands (palms down) near the shoulders as for the traditional press-up exercise. and the exercise is repeated about ten times.Exercise 4 extension in standing the patient stands with the feet well apart and place the hands (fingers pointing backwards) in the small of the back across the belt line. He leans backwards as far as possible, using the hands as a fulcrum, and then returns to neutral standing. The exercise is repeated about ten times.

Other: mckenzie exercises

traditional physiotherapy program

ACTIVE COMPARATOR

traditional physiotherapy program is composed of 1-TENS:pulse frequencies\>250 pulses per second (pps), pulse durations\>500 microseconds (µs) and peak-to-peak amplitudes\>60 milliamperes (mA), pulse frequency from 0.7 to 108 Hz and a pulse width of 100 μs. Intensity level was instructed to be as high as tolerable.2-Hot pack: heated wrap applied for eight hours, or an electric blanket applied for 25 minutes, and at (104 -113) degree Fahrenheit.3-Ultrasound : 1 or 3 MHz and at amplitude densities between 0.1 W/cm² and 3 W/cm².pulsed.4-strengthening exercises: The exercise program includes a warm-up session (awareness of the back, pelvic tilt, whole-body movement in standing), back extensors, posterior buttocks, abdominals, lateral buttocks, leg muscles, as well as exercises for flexibility. Exercise will be at 60-70% of one repetition maximum (RM), held for 30 s and repeated 2-4 time.
