Effect of a Positional Release Therapy Technique on Hamstring Flexibility
... Improved movement efficiency results in decreased injury risks. 5 Common noninvasive therapies used by clinicians, strength and conditioning professionals, and athletes include positional release therapy (PRT), 6 active release technique (ART), 7,8 trigger point pressure release, [9][10][11][12] and self-myofascial release. [13][14][15] Positional release therapy is a manual therapy that places the muscle in a shortened position to promote muscle relaxation. ...
... One article focused on PRT, 6 2 focused on ART, 7,8 4 focused on a variation of trigger point pressure release, [9][10][11]26 and 3 focused on some form of self-myofascial release. [13][14][15] Nine articles reported pre-and posttreatment ROM measurements or posttreatment measurements between the treatment and control groups. ...

[13][14][15] Nine articles reported pre-and posttreatment ROM measurements or posttreatment measurements between the treatment and control groups. 6,7,[9][10][11][13][14][15]26 Three articles reported pre-and posttreatment muscular activation measurements, 8,13,15 and 3 articles reported muscular force production measurements. 8,13,15 Table 2 presents an overview of the included studies. ...
... Al-Shawabka SA et al. (2013), in their study used PRT and reported that there is decrease in tender points by increasing pressure pain thresholds of trigger points in the upper trapezius muscle with mechanical neck pain patients. 28 Wynne MM et al.(2006), demonstrated reduction in pain and improvement in functional ability using PRT in subjects with plantar fasciitis. 29 Pattanshetty Renu et al. in 2015 organized a study on, "Immediate effect of three soft tissue manipulation tech-niques on pain response and flexibility in chronic plantar fasciitis". ...
Background: Plantar fasciitis (PF) is characterized by inflammation, fibrosis and structural deterioration of foot and there is pain over heel and plantar fascia. Plantar fasciitis pain is gradual in onset, sharp and diffusely located initially which later localizes to medial calcaneal tuberosity. Typically, pain is most severe in the morning which lessens with movement but intensifies with long-standing weight bearing. Plantar fasciitis has been experienced by 10% of the non-athletic population and most typically observed in weight-bearing activities. So, the aim was to study the effects of primal reflex release technique and positional release therapy on pain, functional ability and ankle range in patients with plantar fasciitis. Method: Total 36 patients were recruited for the study as per the selection criteria and were divided into two groups (18 in each group). Group A was treated with primal reflex release technique (PRRT) along with conventional therapy and Group B was treated with positional release therapy (PRT) along with conventional therapy for 7 consecutive days. Intergroup analysis by independent t-test showed statistically significant improvement in pain and functional ability (P value ≤ 0.001). Conclusion: Primal reflex release technique along with conventional therapy was found to be more predominant in improving pain and functional ability than positional release therapy along with conventional therapy. Also, Primal reflex release technique along with conventional therapy and positional release therapy along with conventional therapy were equally effective in improving ankle range of motion.
... In contrast, (Trevor et al., 2005) provides study to investigate the effect of positional release therapy (PRT) technique to increase hamstring flexibility, Hamstring flexibility was assessed before and after each technique by measuring the popliteal angle during maximal active knee extension performed in sitting, A blinded evaluator measured popliteal angles on digital photographs using a standard protractor. The finding suggested that the PRT technique is not effective to increase knee extension in healthy subjects who have decreased hamstring flexibility. ...
Introduction: Chronic Mechanical Low Back Dysfunction (CMLBD) is the most common problem of the working-age population in modern industrial society; it causes a substantial economic burden due to the wide use of medical services and absence from work. Aim of work: To investigate the effect of positional release technique on patients with chronic mechanical low back pain. Materials and Methods: Thirty two patients from both sexes were diagnosed with CMLBP, aged 20 to 45 years and were divided randomly into two equal groups; sixteen patients each; group A (control group) received therapeutic exercises that include (Stretch and Strength exercises for back and abdominal muscles). Group B (experimental group) received therapeutic exercises with positional release technique; treatment was applied 3 days/week for 4 weeks. Pain was measured by Visual Analogue Scale, Lumbar range of motion was measured by Inclinometer and Functional disability was measured by Oswestry disability scale. Measurements were taken at two intervals pre-treatment and post-treatment. Results: Data obtained was analyzed via paired and unpaired t-Test. There were statistical differences between the 2 groups, where the experimental group showed greater improvement than control group. Conclusion: Positional release technique

... Trevor B Birmingham found that positional release therapy and sham technique result in similar level of flexibility. [26] He indicates that the PRT technique is not effective to improve knee extension because of hamstring tightness. This supports our study which suggests that PRT is not much effective than MET in improving hamstring flexibility. ...
... According to the proprioception theory, movement in the direction of greatest ease reduces the tension on the affected tissues and minimizes stimulation of the affected proprioceptors in PRT. In fact, positioning the muscle in the position of ease for a short period in PRT (90 seconds for general orthopedic patients and 3 minutes for neurologic patients) (1) reduces the gamma gain, thereby allowing the hyperactive reflex arc to return to its original state and increase ROM (30). ...
Background: Positional release therapy (PRT) has been suggested as an effective treatment for myofascial trigger points (MTrPs). Considering the mechanism of PRT, a new modified technique, known as Manual Passive Muscle Shortening (MPMS), is introduced for the treatment of MTrPs. Objectives: To compare the effects of MPMS and PRT on the sensitivity of latent MTrPs in the upper trapezius and determine the active cervical lateral flexion range. Methods: In this double-blind randomized controlled trial, 30 female university students, who were identified with latent MTrPs of the upper trapezius, were recruited from Tabriz University of Medical Sciences, Tabriz, Iran. The participants were randomly allocated into experimental (n, 15) and control (n, 15) groups. The experimental group was treated with the MPMS technique, while the control group received PRT. The participants took part in 3 treatment sessions, as well as a follow-up session 1 week after the third session. During each session, the second physiotherapist, who was blind to the pretreatment information, applied the appropriate technique. The visual analogue scale (VAS), pressure pain threshold (PPT), and bilateral active range of cervical lateral flexion were recorded to assess the effects of treatment. The first physiotherapist, who was blind to the treatment approach for the participants, recorded the outcomes before treatment, during the first session, after treatment (third session), and in the follow-up. Results: A total of 30 participants were included in the data analysis. In the follow-up, intergroup changes indicated a significant increase in PPT (P = 0.000), a significant decrease in VAS scores (P = 0.002), and a significant increase in the right lateral flexion (P = 0.012) in the experimental group. Left lateral flexion also increased in this group, although it was not statistically significant (P = 0.254). At the end of the study, there were no significant differences between the groups (P > 0.05). Conclusions: According to the results, both MPMS and PRT were effective techniques in immediate pain relief of upper-trapezius MTrPs. Therefore, MPMS may be used as a new technique in the treatment of MTrPs.

... By positioning the patient's muscle in the position of ease for a short period of time, the gamma gain decreases, thereby allowing the hyperactive reflex arc to return to its original state and range of motion to increase. This technique has been proposed for resolving dysfunction in chronic, subacute and acute condition [38]. The treatment duration (90 sec) for Positional release therapy selected for this study produced immediate significant pain relief which further suggests that this time duration may be used in similar clinical set-ups in alleviating pain in chronic plantar fasciitis [33]. ...
Background and Objectives: Plantar fasciitis is a common foot disorder in which patients have pain and tenderness at the sole of the foot. Rest, exercises, orthotics, taping, cryotherapy, therapeutic ultrasound, electrical stimulation, whirlpool bath, and iontophoresis have been widely used to relieve plantar pain. Long term use of manual therapy techniques like myofascial release technique, positional release therapy and passive stretching have been used in the past to reduce pain and improve ankle range of motion. The present study aimed to evaluate and compare the immediate effectiveness of myofascial release technique, positional release therapy and passive stretching on pain response and ankle flexibility in chronic plantar fasciitis.
Material and methodology: A total of 60 participants with chronic plantar fasciitis were randomly allocated to Group A (myofascial release group) and Group B (positional release group) and Group C (passive stretching). Therapeutic ultrasound with intensity of 1W/cm2 and frequency of 1MHz for 5 min was given for a single session to all the patients and then given the manual techniques. Visual analogue scale, range of motion of the ankle were outcome measures that were assessed pre- and immediately post-interventional.
Results: The study demonstrated statistical significant reduction in pain, in all three groups (p
Context:
Ulnar nerve is formed by the branches of Medial cord of
the brachial plexus and is one of the main nerves of upper limb.
Ulnar nerve passes posterior to medial epicondyle of humerus
so may be stretched or compressed in elbow movement.
Objective:
To assess the ability of ulnar nerve motor fibers to pass
stimulus in three different position of elbow joint (0o, 90 o, 120 o
of elbow flexion).
Material and Methods:
The cross-sectional observational study was conducted on
30 normal healthy individuals (aged between 18 to 25 years) in
Government Spine Institute, Civil Hospital, Ahmedabad. Subjects
exposed to factors affecting nerve conduction velocities e.g.
smokers, alcoholic, diabetic etc. were not included in the study.
Subjects were selected by random sampling technique. Subjects
were given supine lying position to measure latency (from artifact
to first negative deflection) and amplitude (peak to peak) of right
ulnar nerve from above and below elbow in three different
positions of elbow (0 o, 90 o, 120 o of flexion) using EMG
instrument (RMS EMG EP MK-II, Version 1.1), measure tape,
thermometer, weighing-machine, height-scale, universal goniometer,
sketch pen, spirit, pen, electrode gel, cotton and
micropore adhesive tape.
Results:
Statistical analysis was done with ANNOVA test. F values
for below elbow latency, above elbow latency, below elbow
amplitude, above elbow amplitude are 0.0699, 0.1534, 0.1488,
and 0.2336 respectively. Results showed insignificant difference
at 0.05significance level in latency and amplitude of ulnar nerve
in three different positions of elbow.
Conclusion:
Study concludes that there is no effect of elbow positions
on latency and amplitude during ulnar motor nerve conduction.
