Management of a female with chronic sciatica and low back pain: A case report

This case report describes therapeutic exercise management for a female with a chief complaint of right sciatica and secondary low back pain (LBP). The patient was a 61-year old female with chronic right sciatica and LBP. At initial examination she reported pain at 9 on a scale of 10, with 10 being the most severe, demonstrated a straight leg raise (SLR) limited to 45°, and a positive Ober's test. The Oswestry Disability Index (ODI) was 40%. The first six weeks (five visits) the patient was instructed in stabilization and spinal flexion exercises. After noting limited improvement, the intervention plan was revised for 13 additional weeks (10 visits) to include the following exercises to reposition and stabilize the pelvis: muscle activation of the left hamstrings, adductors, gluteus medius, abdominals, and right gluteus maximus; stretching the left posterior hip capsule; and muscle inhibition for the paraspinals. After five visits (six weeks), the patient reported 6/10 pain and leg pain. At discharge, patient reported 0/10 pain, SLR was 70°, the Ober's test was negative, and the Oswestry Disability Index was 0%. Stabilization and flexion exercises resulted in limited outcomes and did not eliminate the right sciatica symptoms. The addition of muscle activation, muscle inhibition, and a left hip capsule flexibility exercises resulted in remarkable outcomes and appears to be beneficial for eliminating pain and improving function for this woman with chronic right sciatica/LBP.     

Effect of the Individual Strengthening Exercises for Posterior Pelvic Tilt Muscles on Back Pain,Pelvic Angle,and Lumbar ROM of a LBP Patient with Excessive Lordosis: A Case Study

[Purpose] The purpose of this study was to document the effect of individual strengthening exercises for posterior pelvic tilt muscles on back pain, pelvic tilt angle, and lumbar ROM of a low back pain (LBP) patient with excessive lordosis. [Subjects] The subject was a 28 year-old male with excessive lordosis who complained of severe LBP at the L3 level. [Methods] He performed individual strengthening exercises for the posterior pelvic tilt muscles (rectus abdominis, gluteus maximus, hamstring). [Results] Pelvic tilt angles on the right and left sides recovered to his normal ranges. Limited lumbar ROM increased, and low back pain decreased. [Conclusion] We suggest that an approach of individual resistance exercises is necessary for the effective and fast strengthening of the pelvic posterior tilt muscles in case of LBP with excessive lordosis.Key words: LBP, Lordosis, Posterior pelvic tilt     

Effects of Individual Strengthening Exercises on Subdivisions of the Gluteus Medius in a Patient with Sacroiliac Joint Pain

[Purpose] We investigated the effects of individual strengthening exercises for subdivisions of the gluteus medius in a patient with sacroiliac joint pain. [Subject] A 32 year-old female who complained of pain in the posterior area of the left iliac crest and sacroiliac joints over a period of 6 months was the subject of this study. [Methods] She performed individual strengthening exercises for subdivisions of the gluteus medius over 3 weeks. Pain-provocation tests and VAS scores were evaluated before and after the intervention. [Results] After individual strengthening exercises for subdivisions of the gluteus medius, the subject showed no pain in the Gaenslen, Patrick, or REAB tests for the left sacroiliac joint. The VAS score was less the 3/10, compared with 7/10 initially. [Conclusion] Individual strengthening exercises for the subdivisions of the gluteus medius were effective at reducing SI joint pain for this patient.Key words: Gluteus medius, Pain-provocation tests, Sacroiliac joint pain     

Effects of double air-cushion biofeedback exercises in a patient with sacroiliac joint pain

[Purpose] We developed a double air-cushion biofeedback device to be used for sacroiliac (SI) joint exercises and investigated the effects of exercising using the device in a patient with SI joint pain. [Subject] A 40-year-old man, who complained of pain in the left posterior iliac crest area and SI joints over a 6-month period participated. [Methods] After a 4-week exercise program using the double air-cushion biofeedback device, the subject was assessed using the Gaenslen, Patrick, posterior shear (POSH), and resisted abduction (REAB) tests. [Results] After performing exercise designed to strengthen subdivisions of the gluteus medius, the subject had no pain in the Gaenslen, Patrick, POSH, or REAB tests of the SI joint. The visual analog scale (VAS) score for pain on palpation of the left posterior iliac crest area decreased to 4/10 from an initial score of 7/10. [Conclusion] Exercises with the double air-cushion biofeedback device improved hip asymmetry, SI joint mobility, and muscle strength.Key words: Biofeedback, Pain-provocation tests, Sacroiliac joint pain     

Electromyographic analysis of gluteus maximus and hamstring activity during the supine resisted hip extension exercise versus supine unilateral bridge to neutral

Hip extension strengthening exercises which maximize gluteus maximus contributions and minimize hamstring influences may be beneficial for persons with hip pain. This study’s aim was to compare muscle activation of the gluteus maximus and hamstrings from healthy subjects during a supine resisted hip extension exercise versus supine unilateral bridge to neutral. Surface electromyographic (EMG) signals were obtained from the right gluteus maximus and hamstrings in 13 healthy male and 13 healthy female subjects. Maximum voluntary isometric contractions (MVICs) were collected to normalize data and permit meaningful comparisons across muscles. Peak median activation of the gluteus maximus was 33.8% MVIC for the bridge and 34.7% MVIC for the hip extension exercise, whereas peak median recruitment for hamstrings was 28.4% MVIC for the bridge and 51% MVIC for the hip extension exercise. The gluteus maximus to hamstrings ratio was compared between the two exercises using the Wilcoxon signed-ranks test (α = 0.05). The ratio (p = 0.014) was greater in the supine unilateral bridge (median = 111.3%) than supine hip extension exercise (median = 59.2%), suggesting a reduction of hamstring recruitment in the unilateral bridge to neutral compared to the supine resisted hip extension exercise. The supine hip extension exercise demonstrated higher EMG activity of hamstrings in comparison with supine unilateral bridge and, therefore, may be less appropriate in subjects who need to increase gluteus maximus activation.     

Changes in pelvic floor and diaphragm kinematics and respiratory patterns in subjects with sacroiliac joint pain following a motor learning intervention: a case series

This study was a case series design. The objectives of the study were to investigate the ability of a motor learning intervention to change aberrant pelvic floor and diaphragm kinematics and respiratory patterns observed in subjects with sacroiliac joint pain (SIJP) during the active straight leg raise (ASLR) test. The ASLR test is a valid and reliable tool to assist in the assessment of load transference through the pelvis. Irregular respiratory patterns, decreased diaphragmatic excursion and descent of the pelvic floor have been reported in subjects with SIJP during this test. To date the ability to alter these patterns has not been determined. Respiratory patterns, kinematics of the diaphragm and pelvic floor during the ASLR test and the ability to consciously elevate the pelvic floor in conjunction with changes in pain and disability levels were assessed in nine subjects with a clinical diagnosis of SIJP. Each subject then undertook an individualized motor learning intervention. The initial variables were then reassessed. Results showed that abnormal kinematics of the diaphragm and pelvic floor during the ASLR improved following intervention. Respiratory patterns were also influenced in a positive manner. An inability to consciously elevate the pelvic floor pre-treatment was reversed. These changes were associated with improvement in pain and disability scores. This study provides preliminary evidence that aberrant motor control strategies in subjects with SIJP during the ASLR can be enhanced with a motor learning intervention. Positive changes in motor control were associated with improvements in pain and disability. Randomized controlled research is required to validate these results.     

The relationship beween posture and back muscle endurance in industrial workers with flexion-related low back pain

This preliminary cross-sectional study was undertaken to determine if there were measurable relationships between posture, back muscle endurance and low back pain (LBP) in industrial workers with a reported history of flexion strain injury and flexion pain provocation. Clinical reports state that subjects with flexion pain disorders of the lumbar spine commonly adopt passive flexed postures such as slump sitting and present with associated dysfunction of the spinal postural stabilising musculature. However, to date there is little empirical evidence to support that patients with back pain, posture their spines differently than pain-free subjects. Subjects included 21 healthy industrial workers and 24 industrial workers with flexion-provoked LBP. Lifestyle information, lumbo-pelvic posture in sitting, standing and lifting, and back muscle endurance were measured. LBP subjects had significantly reduced back muscle endurance (P < 0.01). LBP subjects sat with less hip flexion, (P = 0.05), suggesting increased posterior pelvic tilt in sitting. LBP subjects postured their spines significantly closer to their end of range lumbar flexion in 'usual' sitting than the healthy controls (P < 0.05). Correlations between increased time spent sitting, physical inactivity and poorer back muscle endurance were also identified. There were no significant differences found between the groups for the standing and lifting posture measures. These preliminary results support that a relationship may exist between flexed spinal postures, reduced back muscle endurance, physical inactivity and LBP in subjects with a history of flexion injury and pain.     

Effect of Individual Strengthening Exercises for Anterior Pelvic Tilt Muscles on Back Pain,Pelvic Angle,and Lumbar ROMs of a LBP Patient with Flat Back

[Purpose] The purpose of this paper is to report the effect of individual strengthening exercises for the anterior pelvic tilt muscles on back pain, pelvic tilt angle, and lumbar ROM of a low back pain (LBP) patient with flat back. [Subject] A 37 year-old male, who complained of LBP pain at L3-5 levels with flat back, participated. [Methods] He performed the individual strengthening exercises for anterior pelvic tilt muscles (erector spinae,iliopsoas, rectus femoris). [Results] Pelvic tilt angles of the right and left sides were recovered to normal ranges. His lumbar ROMs increased, and low back pain decreased. [Conclusion] We suggest that individual resistance exercises are a necessary approach for effective and fast strengthening of pelvic anterior tilt muscles in LBP with flat back.Key words: Anterior pelvic tilt, Flat back syndrome, LBP     

CLINICAL APPLICATION OF THE RIGHT SIDELYING RESPIRATORY LEFT ADDUCTOR PULL BACK EXERCISE

Problem:

Lumbopelvic‐femoral conditions are common and may be associated with asymmetrical musculoskeletal and respiratory impairments and postural mal‐alignment called a Left Anterior Interior Chain (AIC) pattern. An inherent pattern of asymmetry involves the trunk/ribs/spine/pelvis/hip joints and includes the tendency to stand on the right leg and shift the center of gravity to the right which may result for example, in a tight left posterior hip capsule, poorly approximated left hip, long/weak left adductors, internal obliques (IO) and transverse abdominus (TA), short/strong/over active paraspinals and muscles on the right anterior outlet (adductors, levator ani and obturator internus), a left rib flare and a decreased respiratory diaphragm zone of apposition (ZOA).

The Solution:

A therapeutic exercise technique that can address impairments associated with postural asymmetry may be beneficial in improving function, reducing and/or eliminating pain causation, and improving breathing. The Right Sidelying Left Respiratory Adductor Pull Back is an exercise designed to affect alignment of the lumbopelvic‐femoral region by influencing the left posterior ischiofemoral ligament, ZOA and right anterior outlet and left anterior inlet (rectus femoris, sartorius), activating/shortening the left adductors, left IO/TA''s and inhibiting/lengthening the paraspinals, bilaterally.

Discussion:

The exercise technique is often used by Physical Therapists, Physical Therapist assistants and Athletic Trainers as an initial exercise to positively affect position/alignment of the lumbopelvic‐femoral region, referred to as “repositioning,” by clinicians who use it. Four published case studies have used similar exercises to address the above impairments associated with a Left AIC pattern and in each 100% improvement in function and pain intensity was described. This particular exercise technique is relatively new and warrants future research.     

Extensibility and stiffness of the hamstrings in patients with nonspecific low back pain

OBJECTIVE: To investigate the extensibility and stiffness of the hamstrings in patients with nonspecific low back pain (LBP). DESIGN: An experimental design. SETTING: A university laboratory for human movement analysis in a department of rehabilitation medicine. PARTICIPANTS: Forty subjects, a patient group (20) and a healthy control group (20). INTERVENTIONS: Subjects laid supine on an examination table with a lift frame, with left leg placed in a sling at the ankle. Straight leg raising, pulling force, and activity of hamstring and back muscles were recorded with electrodes. Patients indicated when they experienced tension or pain. MAIN OUTCOME MEASURES: The lift force, leg excursion, pelvic-femoral angle, first sensation of pain, and the electromyogram of the hamstrings and back muscles measured in an experimental straight-leg raising set-up. RESULTS: The patient group showed a significant restriction in range of motion (ROM) and extensibility of the hamstrings compared with the control group. No significant difference in hamstring muscle stiffness can be assessed between both groups. CONCLUSION: The restricted ROM and the decreased extensibility of the hamstrings in patients with nonspecific LBP is not caused by increased muscle stiffness of the hamstrings, but determined by the stretch tolerance of the patients.     

Lumbar extension exercises in conjunction with mechanical traction for the management of a patient with a lumbar herniated disc

ABSTRACT

Low back pain resulting from lumbar disc herniation is a common reason for referral for physical therapy. There is no evidence to support the management of lumbar disc herniation and derangement using mechanical traction combined with lumbar extension exercises. Therefore, the purpose of this case report was to describe and discuss the use of mechanical traction in conjunction with lumbar extension exercises for a patient with a lumbar herniated disc. The patient was a 49-year-old male referred to physical therapy with a medical diagnosis of a lumbar herniated disc at L5-S1 with compression of the L5 nerve root confirmed by MRI. The patient's chief complaint was pain over the left lumbosacral and central lumbar region with radiating pain into the left buttock accompanied by numbness and tingling in the left lower leg and foot. The patient was seen for a total of 14 visits. The first 5 days (2 weeks) of therapy consisted of lumbar extension exercises. For the following nine visits (over a 3-week period), mechanical traction was added as an adjunct to the extension exercises. Outcome measures included the Oswestry Disability Questionnaire, Back Pain Function Scale (BPFS), and the Numeric Pain Rating Scale (NPRS). Results from initial evaluation to discharge (Oswestry: 36% to 0%; BPFS: 33/60 to 57/60; NPRS: 7/10 to 0/10) demonstrated that the patient no longer experienced low back pain and improved in terms of functional status and pain-related disability. The patient no longer complained of numbness and tingling in the left lower extremity and the goals for the patient had been attained. The data from this case report suggests lumbar extension exercises in conjunction with mechanical traction facilitated the patient's improvement in pain and return to prior level of function.     

Effect of abduction and external rotation of the hip joint on muscle onset time during prone hip extension with knee flexion

[Purpose] This study investigated the effect of hip position on muscle onset time during prone hip extension with knee flexion. [Subjects] The study included 21 healthy male volunteers. [Methods] Muscle onset times of the right gluteus maximus, right hamstrings, bilateral lumbar erector spinae, and bilateral lumbar multifidus were measured using surface electromyography during right hip extension with knee flexion in the prone position. Measurements were made with the hip in 3 positions: (1) neutral, (2) abduction, and (3) abduction and external rotation. [Results] Gluteus maximus onset relative to the hamstrings was significantly earlier with hip abduction and with hip abduction and external rotation compared with that with the hip in the neutral position. Gluteus maximus onset relative to the hamstrings was significantly earlier with hip abduction and external rotation compared with that with hip abduction. The bilateral multifidus and left lumbar erector spinae onset times relative to the hamstrings were significantly earlier with hip abduction and external rotation compared with those with hip abduction and with the hip in the neutral position. [Conclusion] Abduction and external rotation of the hip during prone hip extension with knee flexion is effective for advancing the onset times of the gluteus maximus, bilateral multifidus, and contralateral lumbar erector spinae.Key words: Prone hip extension with knee flexion, Hip joint position, Muscle onset time     

Effect of low back pain on the muscles controlling the sitting posture

[Purpose] The purpose of the current study was to reveal the association between posture control and muscle activity by measuring the trunk and hip joint muscle activities in the upright and slump sitting positions in both the healthy participants and patients with recurrent lower back pain. [Participants and Methods] We recruited eleven patients of recurrent lower back pain and ten healthy participants. During the maintenance of the two types of posture, upright and slump, we collected the surface electromyography data. We assessed the following muscles: rectus abdominis, external oblique, thoracic erector spinae, lumbar erector spinae, internal oblique, lumbar multifidus, iliacus, serratus anterior, rectus femoris, tensor fascia latae, and gluteus maximus. We studied the differences in spinal–pelvic curvature and muscle activity between the upright and slump positions in each group. [Results] In the healthy group, comparison of the muscle activity in upright and slump positions for both the trunk (external oblique, internal oblique, lumbar erector spinae, and lumbar multifidus), and the hip muscles (iliacus and gluteus maximus) showed a significant decrease in activity in the slump position. In the group with recurrent lower back pain, although the external oblique, lumbar erector spinae and lumbar multifidus showed reduced activity in slump position, these values were smaller when compared to those in the healthy group. [Conclusion] This study aimed to clarify the relationship between posture (upright and slump) and the activity of the trunk and hip joint muscles in the healthy participants and the patients with recurrent lower back pain. The results indicated that postural changes caused by recurrent lower back pain significantly affected the activity of the muscles involved in controlling the posture.Key words: Sitting posture, Muscle control, Low back pain     

Acute affective responses to prescribed and self-selected exercise sessions in adolescent girls: an observational study

Background

Thigh muscle injuries commonly occur during single leg loading tasks and patterns of muscle activation are thought to contribute to these injuries. The influence trunk and pelvis posture has on hip and thigh muscle activation during single leg stance is unknown and was investigated in a pain free population to determine if changes in body posture result in consistent patterns of changes in muscle activation.

Methods

Hip and thigh muscle activation patterns were compared in 22 asymptomatic, male subjects (20–45 years old) in paired functionally relevant single leg standing test postures: Anterior vs. Posterior Trunk Sway; Anterior vs. Posterior Pelvic Rotation; Left vs. Right Trunk Shift; and Pelvic Drop vs. Raise. Surface EMG was collected from eight hip and thigh muscles calculating Root Mean Square. EMG was normalized to an “upright standing” reference posture. Repeated measures ANOVA was performed along with associated F tests to determine if there were significant differences in muscle activation between paired test postures.

Results

In right leg stance, Anterior Trunk Sway (compared to Posterior Sway) increased activity in posterior sagittal plane muscles, with a concurrent deactivation of anterior sagittal plane muscles (p: 0.016 - <0.001). Lateral hip abductor muscles increased activation during Left Trunk Shift (compared to Right) (p :≤ 0.001). Lateral Pelvic Drop (compared to Raise) decreased activity in hip abductors and increased hamstring, adductor longus and vastus lateralis activity (p: 0.037 - <0.001).

Conclusion

Changes in both trunk and pelvic posture during single leg stance generally resulted in large, predictable changes in hip and thigh muscle activation in asymptomatic young males. Changes in trunk position in the sagittal plane and pelvis position in the frontal plane had the greatest effect on muscle activation. Investigation of these activation patterns in clinical populations such as hip and thigh muscle injuries may provide important insights into injury mechanisms and inform rehabilitation strategies.

     

The Effects of Manual Physical Therapy and Therapeutic Exercise on Peripartum Posterior Pelvic Pain: Two Case Reports

Abstract

Peripartum posterior pelvic pain is a clinical enigma commonly encountered by physical therapists. It is hypothesized that the release of relaxin hormone during pregnancy may result in ligament laxity, which could lead to sacroiliac instability resulting in pain and decreased function. The purpose of these case reports was to describe the effects of manual physical therapy and therapeutic exercise on a peripartum patient with reports of posterior pelvic pain. Two patients referred to physical therapy by their obstetrician during their pregnancy were recruited for these case reports. During the initial examination, both patients completed a number of self-report measures including the Oswestry Disability Index, a body diagram, and the Numeric Pain Rating Scale. Both patients were treated with muscle energy techniques directed at pelvic and sacral positional faults and therapeutic exercise consisting of transverse abdominis and multifidus neuromuscular re-education; isometric hip abduction and external rotation; and a force closure sacroiliac stabilization program directed at neuromuscular re-education of the anterior and posterior oblique sling systems (hip adductors-contralateral obliques and gluteus maximus-contralateral latissimus dorsi combinations). At the time of discharge, both patients again completed the self-report outcome measures as well as a global rating of change. Both patients demonstrated a clinically meaningful improvement in their pain levels as well as perceived disability. In addition, both rated their global rating of change as "a great deal better." These case reports provide preliminary evidence suggesting that manual physical therapy and therapeutic exercise may be an effective intervention strategy for peripartum patients reporting posterior pelvic pain.     

Pain and hip lateral rotator muscle strength contribute to functional status in females with patellofemoral pain

Background and Purpose . Patellofemoral pain (PFP) is a common musculoskeletal pain condition, especially in females. Decreased hip muscle strength has been implicated as a contributing factor, yet the relationships between pain, hip muscle strength and function are not known. The purpose of this study was to test the hypothesis that pain and hip muscle strength explain unique portions of variance in the functional status of females with PFP. Methods . An observational, cohort study was conducted. The subjects for this study were twenty‐one females with PFP (age: 26 ± 7 years; height: 163 ± 4 cm; and body mass: 62 ± 10 kg). Subjects had a minimum pain duration of two months (mean pain duration: 4.9 ± 3.6 years). The main measures were pain during a unilateral squat, measured with a visual analogue scale; isometric muscle force of gluteus medius, gluteus maximus and hip lateral rotators; and Kujala score (self‐report measure of function). Hierarchical multiple regression analysis was performed with Kujala score as the dependent variable. Pain and hip lateral rotator muscle strength were independent variables, entered in that order. Other strength measures were not correlated with the Kujala score, and as such, were not used in the analysis. Results . Pain explained 22% of the variance in the Kujala score (p = 0.03). Hip lateral rotator strength explained an additional 14% of the variance, after accounting for pain level (p = 0.06). Conclusions . Pain and hip lateral rotator strength contributed to the functional status of females with PFP. Improving pain and hip lateral rotator muscle strength may improve function in females with this common pain condition. Copyright © 2009 John Wiley & Sons, Ltd.
