Comparison of pressure release, phonophoresis and dry needling in treatment of latent myofascial trigger point of upper trapezius muscle.

J Back Musculoskelet Rehabil 2019 ;32(4):587-594

Background: Latent myofascial trigger point (LMTP) is a small hypersensitive area in skeletal muscles that becomes painful under compression or stimulation. LMTPs are relevant for various musculoskeletal disorders. Although several treatments have been introduced to treat LMTP, the most efficient one is yet to be found.

Objective: The main purpose of the present study was to compare pressure release, phonophoresis of betamethasone and dry needling on the upper trapezius latent myofascial trigger point.

Methods: Sixty participants (mean ± SD age, 23.6 ± 2.1 y), with at least one latent myofascial trigger point in the upper trapezius muscle, participated in this study. Subjects were randomly divided into three groups (pressure release, phonophoresis with betamethasone and dry needling groups) for two weeks. Pain intensity, pain pressure threshold and active cervical range of motion were assessed.

Results: Significant pain decrease, active cervical range of motion and pain pressure threshold increase were observed in the three groups (p< 0.001). The dry needling and phonophoresis groups reported more significant improvement compared to the pressure release group (p< 0.001). There was no difference between the dry needling and phonophoresis groups.

Conclusions: Considering the significant, positive effects of all three methods, dry needling and phonophoresis seem to be more effective than pressure release.

The effects of arm movement on reaction time in patients with latent and active upper trapezius myofascial trigger point.

Med J Islam Repub Iran 2015 16;29:295. Epub 2015 Nov 16.

Assistant Professor, Physical Therapy Department, Rehabilitation Faculty, Iran University of Medical Sciences, Tehran, Iran.

Background: Myofascial pain syndrome is a significant source of mechanical pain. The aim of this study was to investigate the effects of arm movement on reaction time in females with latent and active upper trapezius myofascial trigger point.

Methods: In this interventional study, a convenience sample of fifteen women with one active MTP, fifteen women with one latent MTP in the upper trapezius, and fifteen normal healthy women were participated. Participants were asked to stand for 10 seconds in an erect standing position. Muscle reaction times were recorded including anterior deltoid (AD), cervical paraspinal (CP) lumbar paraspinal (LP), both of upper trapezius (UT), sternocleidomastoid (SCM) and medial head of gastrocnemius (GcM). Participants were asked to flex their arms in response to a sound stimulus preceded by a warning sound stimulus. Data were analyzed using one-way ANOVA Test.

Results: There was significant differences in motor time and reaction time between active and control groups (p< 0.05) except for GcM. There was no significant difference in motor time between active and passive groups except for UT without MTP and SCM (p< 0.05). Also, there were no significant differences in motor times between latent MTP and control groups. Furthermore, there was no significant difference in premotor times between the three groups.

Conclusion: The present study shows that patients with active MTP need more time to react to stimulus, but patients with latent MTP are similar to healthy subjects in the reaction time. Patients with active MTP had less compatibility with environmental stimulations, and they responded to a specific stimulation with variability in Surface Electromyography (SEMG).

Strength of hip muscle groups in sedentary women with patellofemoral pain syndrome.

J Back Musculoskelet Rehabil 2014 ;27(3):299-306

Department of Physiotherapy, School of Rehabilitation, Tehran University of Medical Sciences, Tehran, Iran.

Objective: To compare the strength of hip muscle groups in sedentary women with bilateral patellofemoral pain syndrome (PFPS) with a matched control group of sedentary women without PFPS.

Methods: Twenty four women between 19 and 23 years of age (PFPS group, n=12; control group, n=12) participated in this study. Strength for all 6 hip muscle groups was measured bilaterally in all subjects using a stabilized Hand-held dynamometer.

Results: The hip musculature of sedentary women with bilateral PFPS was statistically weaker (range 31%-52%; p< 0.001) than that of the control group for all muscle groups.

Conclusion: This study demonstrated a statistically significant weakness of hip muscle groups in sedentary women with PFPS.

Ankle rotation changes and its influences in knee osteoarthritis.

Med J Islam Repub Iran 2013 May;27(2):67-76

PhD student, School of Biomedical Engineering, Amir Kabir University of Technology (Tehran Polytechnic), Tehran, Iran.

Background: Biomechanical factors are known to be important in knee osteoarthritis (OA) development and progression. This study was designed to determine changes of hamstrings muscle activation, knee adduction moment and ankle rotation angle in two knee osteoarthritis (mild and moderate) and a healthy control group.

Methods: 16 females (10 with mild and 6 with moderate medial knee osteoarthritis) and 10 control matched females were recruited. A 3D gait analysis was performed on the subjects while they walked along the walkway. Electromyography data was also collected during gait from lateral and medial hamstrings. Post Hoc Tukey HSD (multi comparison) was performed to compare knee adduction moment, ankle rotation angle and medial and lateral hamstrings activity at early and late stance, between three groups.

Results: Ankle rotation angle, knee adduction moment and lateral hamstrings activation showed no significant difference between three groups. Interestingly, medial hamstrings activity was significantly higher at late stance in moderate group compared with asymptomatic and mild groups (p=0.03, 0.02 respectively). Also knee adduction moment at late stance was significantly and directly correlated with ankle rotation angle, and lateral hamstrings activity at early stance was significantly and inversely correlated with this angle.

Conclusions: It can be concluded that, increased lateral hamstrings activity can increase external ankle rotation and consequently decrease knee adduction moment.

The effects of muscle fatigue on dynamic standing balance in people with and without patellofemoral pain syndrome.

Gait Posture 2013 Mar 1;37(3):336-9. Epub 2012 Sep 1.

Musculoskeletal Rehabilitation Research Center, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran.

The aim was to examine the effects of muscle fatigue of knee extensor and hip abductor muscles on dynamic standing balance of patients with patellofemoral pain syndrome (PFPS) compared to their healthy matched controls. Thirty participants (15 with PFPS, 15 controls) were recruited. Isolated muscle fatigue of two muscles was induced isokinetically in three separate sessions (one practice and two testing sessions) with a rest interval of at least 72h. In each testing session, fatigue protocol of only one muscle group was performed for the both legs with a rest time of 30min. After determining peak torque, participants were encouraged to perform continuous maximal concentric-eccentric contraction of the target muscle until the torque output dropped below 50% of peak value for 3 consecutive repetitions. Immediately after the completion of the fatigue protocol, balance testing of participants was undertaken during single leg standing using the Biodex stability system. Balance stability measures included the overall, anteroposterior and mediolateral stability indices (OSI, APSI and MLSI, respectively). Patients exhibited decreased balance stability in the sagittal plane (higher APSI) when compared to controls. Isolated muscle fatigue of the knee extensors and hip abductors reduced balance stability in both study groups. Fatigue of hip abductors was associated with greater balance instability (higher OSI and APSI) than fatigue of knee extensors.
