OBJECTIVE: To compare the effects of transcutaneous electrical nerve
stimulation (TENS) versus therapeutic ultrasound (US) on pain intensity
and cervical range of motion (ROM) in patients with upper trapezius
myofascial trigger points.
METHODS: Sixty-four patients, selected from Institute of Physical
Medicine & Rehabilitation and Rabia Moon Trust Hospital were divided
into two groups. Group-A was treated with TENS and upper trapezius
stretching while group-B was treated with US and upper trapezius
stretching. Both groups received 12 sessions of treatment, 6 times a
week for two weeks. Pre and post-treatment evaluation of pain intensity and cervical ROM was made through numerical pain rating scale (NPRS) and goniometer.
RESULTS: Mean pre & post-treatment pain intensity score (PIS),
was 5.16±1.09 & 2.62 ± 1.23 in Group-A (p<0.01) and 5.87±1.21 &
0.84±1.01 in Group-B (p<0.05). Mean pre & post-treatment left lateral
flexion (LLF) was 32.01±8.00 & 37.09±6.62 in Group-A (p<0.01) and
31.71±6.76 & 40.12±4.52 in Group-B (p<0.01). Mean pre & post-treatment right lateral flexion (RLF), was 30.87±7.15 & 36.01±6.92 in
Group-A and 32.09±6.54 & 40.81±4.78 in Group-B (p<0.01). Mean
change in PIS was 2.54±0.14 & 5.03±0.2 in Group-A & Group-B respectively (p<0.05). Mean change in LLF, was 5.08±1.38 & 8.41±2.24 in Group-A & Group-B respectively (p <0.05). Mean change in RLF, was 5.14±0.23 & 8.72±1.76 in Group-A & Group-B respectively (p <0.05).
CONCLUSION: Both therapeutic ultrasound and TENS resulted in
significant improvement in pain intensity and cervical ROM, in patients
having upper trapezius trigger points. Ultrasound was clinically more
effective as compared to TENS.
