Prone planking exercises have been used by rehabilitation professionals to activate torso muscles in healthy persons and those with low back pain. The aim of this study was to compare the magnitude of electromyographic (EMG) muscle activation from 10 right-sided muscles as demonstrated by the percentage of maximum voluntary isometric contraction (%MVIC) during four planking procedures. Surface EMG activity was acquired from the following muscles: (1) iliocostalis lumborum (IL), (2) longissimus thoracis (LT), (3) lumbar multifidus (LM), (4) rectus abdominis (RA), (5) external oblique (EO), (6) internal oblique (IO), (7) serratus anterior (SA), (8) latissimus dorsi (LD), (9) hamstrings (HS), and (10) gluteus maximus (GM)...

BACKGROUND: There are few published studies with very long-term follow-up of combined intra- and extra-articular anterior cruciate ligament (ACL) reconstruction. PURPOSE: To analyze clinical and radiographic outcomes of over-the-top ACL reconstruction plus extra-articular lateral tenodesis with autologous hamstrings at minimum 20-year follow-up. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Of 60 originally eligible patients who underwent over-the-top ACL reconstruction with double-stranded hamstring tendon (leaving intact graft tibial insertions) and extra-articular lateral plasty (performed with the remnant part of tendons), 52 were prospectively evaluated at a minimum 20-year follow-up (mean follow-up, 24 years; 41 men, 11 women; mean age at time of surgery, 25...

Anterior cruciate ligament (ACL) is the most commonly injured ligament occurs in young adult population, which markedly reduces activity level. Anterior cruciate ligament rupture is a threat to the homeostasis of the knee. So, reconstruction of the ACL is necessary to make them fit and return to their pre-injury activity level. The choice of graft for ACL reconstruction is a matter of debate, with the BPTB graft and quadruple graft of ST-G being the two most popular options. Use of triplet graft of semi-tendinosus tendon alone without sacrificing gracilis is another option...

INTRODUCTION: Lateral tenodesis (LT) is performed to limit the risk of iterative tear following anterior cruciate ligament (ACL) reconstruction in at-risk patients. By adding an extra procedure to isolated ACL graft, LT reconstruction increases operating time and may complicate postoperative course. The objective of the present study was to evaluate the rate of early complications. The study hypothesis was that associating ALL reconstruction to ACL reconstruction does not increase the complications rate found with isolated ACL reconstruction...

BACKGROUND: Tibial aperture fixation with a bioabsorbable interference screw is a popular fixation method in anterior cruciate ligament reconstruction (ACLR). An interference screw containing β-tricalcium phosphate (β-TCP) to improve bony integration and biocompatibility was recently introduced. This study aims to compare the clinical outcomes and radiological results of tunnel enlargement effect between the 2 bioabsorbable fixative devices of pure poly-L-lactic acid (PLLA) interference screws and β-TCP-containing screws, for tibial interference fixation in ACLR using hamstring autografts...

This was a prospective, repeat-treatment, open-label study (NCT01251380) of abobotulinumtoxinA for the management of lower limb spasticity in children who had completed a double-blind study. Children (2-17 years) received injections into the gastrocnemius-soleus complex, and other distal and proximal muscles as required (maximum total dose per injection cycle: 30 U/kg or 1000U). A total of 216 of the 241 double-blind patients entered the extension study and 207 received ≥1 open label injection into the gastrocnemius-soleus; 17-24% of patients also had injections into the hamstrings...

Compression and cold therapy used separately have shown to reduce negative effects of tissue damage. The combining compression and cold therapy (cryocompression) as a single recovery modality has yet to be fully examined. To examine the effects of cryocompression on recovery following a bout of heavy resistance exercise, recreationally resistance trained men (n =16) were recruited, matched, and randomly assigned to either a cryocompression group (CRC) or control group (CON). Testing was performed before and then immediately after exercise, 60 minutes, 24 hours, and 48 hours after a heavy resistance exercise workout (barbell back squats for 4 sets of 6 reps at 80% 1RM, 90 sec rest between sets, stiff legged deadlifts for 4 sets of 8 reps at 1...

BACKGROUND: Hamstring injury with intramuscular tendon involvement is regarded as a serious injury with a delay in return to play (RTP) of more than 50 days and reinjury rates up to 63%. However, this reputation is based on retrospective case series with high risk of bias. OBJECTIVE: Determine whether intramuscular tendon involvement is associated with delayed RTP and elevated rates of reinjury. METHODS: MRI of male athletes with an acute hamstring injury was obtained within 5 days of injury...

The purpose of this study was to examine the impact of foam rolling (FR) on recovery from exercise-induced muscle damage (EIMD). Thirty-seven males performed 40 x 15 m sprints, inducing muscle damage. Immediately following sprinting and in the four days following, perceived muscle soreness, hip abduction range of motion (ROM), hamstring muscle length, vertical jump, and agility measures were recorded. Eighteen subjects (mean ± sd; age 22.4 ± 2.0 yrs; BMI 26.9 ± 4.2 kgm) foam rolled prior to testing each day (FR), while 19 (mean ± sd; age 23...

BACKGROUND: Gluteal strength plays a role in injury prevention, normal gait patterns, eliminating pain, and enhancing athletic performance. Research shows high gluteal muscle activity during a single-leg bridge compared to other gluteal strengthening exercises; however, prior studies have primarily measured muscle activity with the active lower extremity starting in 90 ° of knee flexion with an extended contralateral knee. This standard position has caused reports of hamstring cramping, which may impede optimal gluteal strengthening...

INTRODUCTION: After undergoing anterior cruciate ligament (ACL) reconstruction, patients must recover at least 80% of their hamstring and quadriceps strength to be able to return to sports without risk to the graft. Harvesting of the patellar tendon leads to large deficits in quadriceps strength, while harvesting the hamstring tendons leads to large deficits in hamstring strength. However, there are no published studies on the strength deficit after ACL reconstruction with the fascia lata...

The aim of this study was to assess sciatic nerve conductivity in athletes with a history of hamstring strain injuries. Twenty-seven athletes with a history of hamstring strain injuries were included in the injured group. The control group consisted of 16 uninjured participants. We measured the proximal and distal latencies and calculated the sciatic nerve conduction velocity to evaluate neuronal conductivity. The results were expressed as median values and interquartile ranges. Both proximal latency and distal latency of the injured limb in the injured group were significantly longer than those of the uninjured limb (p<0...

BACKGROUND: Prevention of knee osteoarthritis (OA) following anterior cruciate ligament (ACL) rupture and reconstruction is vital. Risk of postreconstruction knee OA is markedly increased by concurrent meniscal injury. It is unclear whether reconstruction results in normal relationships between tibiofemoral contact forces and cartilage morphology and whether meniscal injury modulates these relationships. HYPOTHESES: Since patients with isolated reconstructions (ie, without meniscal injury) are at lower risk for knee OA, we predicted that relationships between tibiofemoral contact forces and cartilage morphology would be similar to those of normal, healthy knees 2 to 3 years postreconstruction...

INTRODUCTION: Anterior cruciate ligament (ACL) reconstruction can be performed with an autograft, which is most often harvested from the patient's hamstring tendon (HT) or patellar tendon (PT). However, autograft harvesting leads to morbidity that is by no means insignificant.A systematic review of literature was performed to define the incidence of complications related to graft harvesting and the methods to prevent these complications. MATERIALS AND METHODS: In March 2017, a systemic review of literature was performed using the keywords"harvesting", "harvest", "morbidity", "complication", "cruciate ligament"...

Hamstring (HS) muscle injuries are the most common injury in sports. They are correlated to long rehabilitations and have a great tendency to recur. The HS consist of the long head of the biceps femoris, semitendinosus, and semimembranosus. The patient's clinical presentation depends on the characteristics of the lesion, which may vary from strain to avulsions of the proximal insertion. The most recognized risk factor is a previous injury. Magnetic resonance imaging is the method of choice for the injury diagnosis and classification...

INTRODUCTION: A calpain-3 (CAPN3) gene heterozygous deletion (c.643_663del21) was recently linked to autosomal dominant (AD) limb girdle muscular dystrophy. However, the possibility of digenic disease was raised. We describe three families with AD calpainopathy carrying this isolated mutation. METHODS: Probands heterozygous for CAPN3 c.643_663del21 were identified by targeted next generation or whole exome sequencing. Clinical findings were collected for probands and families...
