Comparison of a foam rolling session with active joint motion and without joint motion: A randomized controlled trial

Background

Foam rolling has become a popular form of self-myofascial release or roller massage among health and fitness professionals. Due to this popularity, foam roller devices can be found in many clinical and fitness settings. Despite the popularity, there are still several unknowns regarding foam rolling such the optimal technique. Specifically, there is a lack of research analyzing different foam roll techniques such as combining active joint motion with foam rolling.

Effects of myofascial trigger point dry cupping on pain and function in patients with plantar heel pain: A randomized controlled trial

ObjectiveTo investigate the effects of dry cupping on calf muscle myofascial trigger points (MTrPs) on pain and function in patients with plantar heel pain.MethodsSeventy-one patients were randomly divided into an intervention group or control group. Both groups performed stretching exercises for the calf muscle and plantar fascia and ankle dorsiflexion exercises. The intervention group also received dry cupping. The primary outcome measures were visual analogue scale (VAS), pressure pain threshold (PPT), and patient-specific functional scale (PSFS). The secondary outcomes were ankle dorsiflexion range of motion (ROM) and ankle plantar flexor strength. These measurements were performed at baseline, immediately after intervention, and after 2 days.ResultsCurrent VAS significantly decreased immediately in the intervention group (p = 0.002), but not in the control group (p ≥ 0.220). Morning VAS decreased significantly in both groups (p < 0.001) after 2 days, but decreased more in the intervention group (p = 0.006). Trigger point PPT significantly improved immediately in the intervention group (p = 0.003), but not in the control group (p = 0.112). Both groups improved significantly in PSFS (p < 0.001) and ankle dorsiflexion ROM (p < 0.001). Plantar flexor strength significantly increased immediately in the intervention group (p < 0.001), but not in the control group (p = 0.556).ConclusionAdding dry cupping on calf MTrPs to self-stretching and ankle dorsiflexion exercises for patients with plantar heel pain was superior to only self-stretching and active ankle dorsiflexion exercises in pain, ankle dorsiflexion ROM, and plantar flexor strength.     

Comparison of specific and non-specific treatment approaches for individuals with posterior capsule tightness and shoulder impingement symptoms: A randomized controlled trial

BackgroundPosterior capsule tightness (PCT) is associated with shoulder pain and altered shoulder kinematics, range of motion (ROM), external rotation (ER) strength, and pain sensitization.ObjectiveTo assess the effects of two interventions on shoulder kinematics, Shoulder Pain and Disability Index (SPADI) scores, ROM, strength, and pressure pain threshold (PPT) in individuals with PCT and shoulder impingement symptoms.MethodsIn this prospectively registered randomized controlled trial 59 individuals were randomized to either an Experimental Intervention Group (EIG, n=31) or a Control Intervention Group (CIG, n=28). The low flexion (LF) test was used to determine the presence of PCT. Shoulder kinematics, SPADI scores, internal rotation (IR) and ER ROM, ER strength, and PPT were measured pre- and post-treatment. Those in the EIG received an intervention specific to pain and PCT and those in the CIG received a non-specific intervention, both 4 weeks in duration.ResultsIndividuals in the EIG demonstrated more scapular upward rotation (P=.03; mean difference (MD)=3.3°; 95% Confidence Interval (CI)=1.3°, 4.9°) and improved value on the LF test (P=.02; MD=4.6°; 95%CI=0.7°, 8.6°) than those in the CIG after treatment. Both groups presented less anterior (P<.01; MD=-0.7mm; 95%CI=-1.3mm, -0.2mm) and superior (P<.01; MD=-0.5mm; 95%CI=-0.9mm, -0.2mm) humeral translations, decreased SPADI score (P<.01; MD=-23.6; 95%CI=-28.7, -18.4), increased IR ROM (P<.01; MD=4.6°; 95%CI=1.8°, 7.8°) and PPTs for upper trapezius (P<.01; MD=60.1kPa; 95%CI=29.3kPa, 90.9kPa), infraspinatus (P=.04; MD=47.3kPa; 95%CI=2.1kPa, 92.5kPa), supraspinatus (P<.01; MD=63.7kPa; 95%CI=29.6kPa, 97.9kPa), and deltoid (P<.01; MD=40.9kPa; 95%CI=12.3kPa, 69.4kPa) after treatment.ConclusionThe experimental intervention was more effective at improving PCT as measured through changes in the LF test. No benefit of the specific approach over the non-specific intervention was noted for the remaining variables.     

The effect of foam rollers of varying densities on range of motion recovery

ObjectiveThis study aimed to compare the effect of different density foam rollers on range of motion recovery.MethodTen active men completed two, 3-day trials in random order. During the experimental trials, all participants performed 2 min of foam rolling (FR) using a medium-density (medium trial) or hard-density (hard trial) foam roller on the right posterior thigh after completing the 90-min Loughborough Intermittent Shuttle Test (LIST). The hip joint range of motion (ROM), muscle hardness, and muscle soreness were assessed before and after the LIST and at 0 min, 20 min, 60 min, 24 h, and 48 h after FR intervention. Serum creatine kinase (CK) concentrations were assessed before the LIST and at 60 min, 24 h, and 48 h after FR intervention. The contralateral leg in each trial was used as a control.ResultsThe ROM at 0 min, 20 min, 60 min, 24 h, and 48 h after FR intervention were higher in the right leg (the massage leg) than in the left leg (the contralateral leg) (p < 0.05). In the right leg, the ROM at 0 min after FR intervention was higher than after the LIST (p < 0.05). There were no significant differences between the medium and hard trials for ROM. Muscle hardness, muscle soreness, and serum CK concentration were not affected by FR.ConclusionFR has a positive effect on ROM recovery. Moreover, the two roller densities provided similar ROM recovery.     

Effect of manual compressive therapy on latent myofascial trigger point pressure pain thresholds

ObjectiveThis study compared the effects of 90 s of manual compressive therapy (MCT) on latent myofascial trigger points (LTPs) for 3 sessions per week for 4 weeks to determine changes in individual pressure pain threshold (PPT). A total of 30 (15 males, 15 females; age = 22 ± 4 y/o, height = 175 ± 18 cm, weight = 162.5 ± 57.5 kg) symptomatic subjects with LTPs volunteered for the study.MethodsPPT was measured at baseline and pre- and post-treatment for all 12 sessions with a pressure algometer across the 4-week treatment time frame. The MCT was applied to the control group on their LTP at pressure intended to provide a sham condition (1/10 on verbalized analog scale (VAS)). Two experimental groups had MCT applied either directly on the LTP (d-TP) or in close-proximity to their LTP (cp-TP) at moderate pressure (7/10 on VAS).ResultsThere was a significant increase in PPT from the first through twelfth treatment sessions (p < 0.001, partial η² = 0.914). A significant increase in PPTs between treatment groups was acutely observed from pre- to post-therapy tests (p = 0.001, partial η² = 0.146). The differences between pre- versus post-treatment PPT measures indicated significant differences (d-TP vs. control, p < 0.001; cp-TP vs. control, p = 0.007). No differences were observed between experimental groups (p = 0.215).ConclusionsPPT continued to increase after several weeks of MCT when applied directly on or within 2.5 cm of an identified LTP compared to control.     

SPECIFIC AND CROSS OVER EFFECTS OF MASSAGE FOR MUSCLE SORENESS: RANDOMIZED CONTROLLED TRIAL

Purpose/Background:

Muscle soreness can negatively interfere with the activities of daily living as well as sports performance. In the working environment, a common problem is muscle tenderness, soreness and pain, especially for workers frequently exposed to unilateral high repetitive movements tasks. The aim of the study is therefore to investigate the acute effect of massage applied using a simple device Thera‐band roller Massager on laboratory induced hamstring muscle soreness, and the potential cross over effect to the non‐massaged limb.

Methods:

22 healthy untrained men (Mean age 34 +/− 7 years; mean height 181.7 +/− 6.9 cm; mean weight 80.6 +/− 6.4 kg; BMI: 24.5 +/− 1.3) with no prior history of knee, low back or neck injury or other adverse health issues were recruited. Participants visited the researchers on two separate occasions, separated by 48 hours, each time providing a soreness rating (modified visual analog scale 0‐10), and being tested for pressure pain threshold (PPT) and active range of motion (ROM) of the hamstring muscles. During the first visit, delayed onset muscular soreness of the hamstring muscles was induced by 10 x 10 repetitions of the stiff‐legged dead‐lift. On the second visit participants received either 1) 10 minutes of roller massage on one leg, while the contralateral leg served as a cross over control, or 2) Resting for 10 minutes with no massage at all. Measurement of soreness, PPT and ROM were taken immediately before and at 0, 10, 30 and 60 min. after treatment.

Results:

There was a significant group by time interaction for soreness (p < 0.0001) and PPT (p = 0.0007), with the massage group experiencing reduced soreness and increasing PPT compared with the control group. There was no group by time interaction for ROM (p = 0.18). At 10 min. post massage there was a significant reduction in soreness of the non‐massaged limb in the cross over control group compared to controls but this effect was lost 30 minutes post massage.

Conclusion:

Massage with a roller device reduces muscle soreness and is accompanied by a higher PPT of the affected muscle.

The effect of dry needling & muscle energy technique separately and in combination in patients suffering shoulder impingement syndrome and active trigger points of infraspinatus

ObjectiveThe aim of this study was to investigate the effects of a combination of dry needling (DN) and muscle energy technique (MET) on pain intensity (PI), pressure pain threshold (PPT) and shoulder active range of motion (ROM) in patients with shoulder impingement syndrome and active trigger points in the infraspinatus muscle.Methods39 patients, aged 20–50 participated in this study. All the cases were randomly assigned into three groups: group 1 (n = 13) received DN, group 2 (n = 13) received MET, and group 3 (n = 13) received DN & MET. The patients were treated for three sessions in a one-week period with at least a two-day break between sessions.ResultsThe results showed a significant improvement in visual analog scale (VAS), PPT and shoulder ROM over time (P < 0.001) in all three groups. There were no significant differences BETWEEN VAS (P = 0.406) PPT (P = 0.293), external rotation(EXT.ROT) (0.476), internal rotation (INT.ROT)(P = 0.476) and extension(EXT) (P = 0.574) ROMs in the three groups; however, DN group was significantly more effective on abduction(ABD) (P = 0.003) and flexion(FLEX) (0.012) ROM compared with other two groups.ConclusionIn line with previous studies, the present study found that the application of DN, MET and combined of these treatment on active trigger points in the infraspinatus muscle of patients with shoulder impingement syndrome helps reduce pain, increase PPT and enhance the shoulder ROM. Both techniques are effective in the treatment of trigger points. Nevertheless, DN is more effective in enhancing the ROM of flexion & abduction.     

Study of the mechanisms of action of the hypoalgesic effect of pressure under shock waves application: A randomised controlled trial

ObjectiveTo determine if the perceived pain intensity during the application of shock waves (SWs) is a determinant mechanism in producing hypoalgesic changes in pressure pain thresholds (PPTs) in asymptomatic individuals.DesignA randomised, single-blind controlled trial [NCT03455933].SettingUniversity.ParticipantsSixty-three asymptomatic individuals.InterventionsParticipants were randomised into three groups: 1-SWs causing mild pain (SW-DP); 2-SWs generating moderate pain (SW-MP); and 3-cold pressor test (CPT).Main outcome measurementsBefore and after the intervention, the PPT was evaluated bilaterally at the following points: lateral epicondyle, median nerve in the flexure of the elbow, and tibia.ResultsThe results showed differences between various groups over time for all PPTs assessments, due to the existence of statistically significant differences in the interaction group x times (dominant arm lateral epicondyle [P < 0.001; η²p = 0.255]; dominant arm median nerve [P = 0.001; η²p = 0.212]; nondominant arm lateral epicondyle [P < 0.001; η²p = 0.275]; nondominant arm median nerve [P < 0.001; η²p = 0.268]; tibia [P = 0.012, η²p = 0.138]). The SW-MP group obtained a significant increase in all the PPT evaluations compared with the SW-DP group (d > 0.80). The CPT group only showed significantly higher results, and of high magnitude (d > 0.80), regarding the SW-DP group for the PPT evaluation in the dominant member. The SW-MP group showed differences compared with the CPT only for the PPT obtained in the nondominant arm.ConclusionsThe findings show that SW treatment generates a hypoalgesic effect on the application point, with moderate pain. Further studies are necessary in order to link these hypoalgesic changes to the activation of the descending inhibitory systems.     

Knee motion and muscle activation patterns are altered in hip osteoarthritis: The effect of severity on walking mechanics

BackgroundKnee function is impaired in individuals with moderate hip osteoarthritis. How this extends to those undergoing total hip arthroplasty is unknown despite the common requirement for knee arthroplasty in this population. The study purpose was to determine whether sagittal plane knee joint movements and quadriceps and hamstring activation patterns differ between individuals with either moderate or severe unilateral hip osteoarthritis, and between ipsilateral and contralateral knees.Methods20 individuals with moderate osteoarthritis and 20 with severe osteoarthritis were recruited. Sagittal knee motion and surface electromyograms from the hamstrings and quadriceps were collected during treadmill walking at a self-selected speed. Principal component analysis captured amplitude and temporal sagittal plane motion and EMG waveform features. Student's t-tests and Analysis of Variance determined between group differences and within/between group leg differences.FindingsThe severe groups' contralateral knee was in greater flexion at initial contact and demonstrated a movement profile of a longer stance phase (p < 0.001). The severe group had reduced sagittal plane knee motion (p < 0.0001); more so in the ipsilateral knee (p < 0.0001). The severe group had greater hamstring (p = 0.009) and quadriceps activation (p < 0.001) overall, specifically mid-stance quadriceps bilaterally (p = 0.002). Ipsilateral sagittal plane knee motion was reduced in both groups. Compared with those with moderate osteoarthritis, individuals with severe osteoarthritis walk with reduced sagittal plane knee motion bilaterally, suggesting prolonged contralateral stance, and elevated mid-stance hamstring and quadriceps activation.InterpretationAltered kinematics and muscle activity could contribute to a greater mechanical demand on the contralateral knee in those with more severe hip osteoarthritis.     

Short-term effect of myofascial trigger point dry-needling in patients with Adhesive Capsulitis

BackgroundAdhesive Capsulitis (AC) is a common disabling musculoskeletal pain condition of unknown etiology related to the shoulder joint. Literature reported the restricted range of motion (ROM) and pain could be the result of myofascial trigger points (MTrPs) in the muscles of the shoulder girdle. Hence, the objective of this study was to assess the short-term effectiveness of MTrP dry needling (DN) in improving ROM, pain, pressure pain threshold (PPT), and physical disability among patients having AC.MethodsIn a single group pre-post experimental study design, a total of 70 clinically diagnosed patients (both male & female, age group between 40 and 65 years) with AC were recruited from three multi-specialty hospitals. The informed consent forms were received from each patient before participating in the study. Each patient received DN for the MTrPs of shoulder girdle muscles for alternative six days. In addition to DN, each patient had received conventional physiotherapy for continuous twelve days which includes electrotherapy modalities and exercises. The pain intensity (visual analog scale), shoulder ROM (Goniometer), disability (shoulder pain and disability index) and PPT (Algometer) were the outcome measures assessed at the baseline and twelfth day of the intervention.ResultsThere was a statistically significant (p < 0.05) improvement in shoulder ROM, pain intensity, shoulder disability, and PPT at the end of the twelve days of intervention as compared to baseline assessment.ConclusionMTrPs-DN techniques may improve the pain, ROM, disability and PPT along with conventional physiotherapy management among patients with AC.     

Smartphone goniometer has excellent reliability between novice and experienced physical therapists in assessing knee range of motion

IntroductionSmartphone app-based goniometer (SG) are emerging as an alternative to Universal Goniometers (UG) in assessing joint range of motion (ROM). This study examined whether the experience level of examiner affected the reliability of assessing knee flexion (KF) and knee extension (KE) ROM using UG and SG.MethodsParticipants with osteoarthritis of the knee or following total knee replacement were recruited. KF and KE ROM using UG and SG were assessed twice by an experienced physical therapist (PT) and a student PT (SPT). Intraclass correlation coefficients (ICC) examined the interrater (experienced PT vs SPT) and intrarater reliabilities (for experienced PT and SPT) in assessing KF and KE ROM for UG and SG. Concurrent relationships were examined between the knee ROM with pain and physical function using Pearson Correlation Coefficient (r).ResultsThe interrater reliability in assessing KF and KE ROM was excellent (ICC>0.90) between novice and experienced examiners. The standard error of measurement (SEM) for novice examiner in assessing KF was 1° and 2° while using UG and SG respectively; whereas the SEM for experienced examiner in assessing KF was 1° irrespective of which device was used. The concurrent relationships between KF and KE ROM with measures of pain and function were divergent (moderate to low correlations; r <0.7; p > 0.05).ConclusionBoth UG and SG have smaller measurement error in assessing KF and KE ROM irrespective of experience level of examiner and therefore no one tool is superior than the other for assessing knee ROM in clinical practice.     

Self-reported sinus headaches are associated with neck pain and cervical musculoskeletal dysfunction: a preliminary observational case control study

Objectives: Headaches can be associated with rhinosinusitis and may present a diagnostic challenge because of symptomatic overlap with other recurring headaches. Neck pain has received extensive attention in migraine, tension-type and cervicogenic headache but not as a comorbid feature of headache in those with rhinosinusitis. This study investigated the occurrence of neck pain and cervical musculoskeletal dysfunction in individuals with self-reported sinus headaches (SRSH).

Methods: Participants with and without SRSH attended a single data collection session. Participants completed the Headache Impact Test (HIT)-6 and the Sino-Nasal Outcome Test (SNOT)-22. Cervical range of motion (ROM), segmental examination, muscle endurance and pressure-pain threshold (PPT) were measured .

Results: Participants included 31 with SRSH (77.4% female; age 43.7 (9.9) years) and 30 without headache. Average symptom duration was 89.7 (±85.6) months. Mean SNOT-22 and HIT-6 scores were 36.2 (15.3) and 56.7 (7.1), respectively. In the SRSH group, 83.9% (n = 26) reported neck pain. There was a significant difference between groups for cervical sagittal (14.3° [5.3°, 23.3°], p = 0.002) and transverse plane ROM (21.5° [12.4°, 30.6°], p < 0.001), but no difference in frontal plane motion (p = 0.017). There were significant between groups difference in neck flexor endurance (19.5 s [10.1 s, 28.9 s], <0.001), segmental dysfunction O-C4 (p < 0.001) but not in PPT (p = 0.04).

Discussion: Neck pain and cervical musculoskeletal dysfunction are common among persons with SRSH and may be a comorbid feature or contributing factor to headaches attributed to rhinosinusitis. Further research is needed to understand these associations.     

Hypoalgesic effects of specific vs non-specific cervical manipulation in healthy subjects: a randomized crossover trial

BackgroundJoint manipulation is generally used to reduce musculoskeletal pain; however, evidence has emerged challenging the effects associated with the specificity of the manipulated vertebral segment. The aim of this study was to verify immediate hypoalgesic effects between specific and non-specific cervical manipulations in healthy subjects.MethodTwenty-one healthy subjects (18–30 years old; 11 males, 10 females) were selected to receive specific cervical manipulation at the C6-7 segment (SCM) and non-specific cervical manipulation (NSCM) in aleatory order. A 48h interval between manipulations was considered. Pressure pain threshold (PPT) was measured pre- and post-manipulation with a digital algometer on the dominant forearm.ResultsThe SCM produced a significant increase in the PPT (P < 0.001) however no difference was observed in the PPT after the NCSM (P = 0.476). The difference between the two manipulation techniques was 37.26 kPa (95% CI: 14.69 to 59.83, p = 0.002) in favor of the SCM groupConclusionSpecific cervical manipulation at the C6-7 segment appears to increase PPT on the forearm compared to non-specific cervical manipulation in healthy subjects.     

Immediate effect of foam roller on pain and ankle range of motion in patients with plantar fasciitis: A randomized controlled trial

Background:Stretching has been proven to be effective on pain and range of motion (ROM) in patients with plantar fasciitis. Despite recent gain in popularity and the proposed theories of effectiveness of foam roller, there is a lack of literature on the effect of foam rolling on plantar fasciitis.Objective:The objective of this study was to compare the effects of foam rolling and stretching on pain and ankle ROM in patients with plantar fasciitis.Methods:A total of 50 participants were included and randomly allocated to the stretching and foam roller groups. Visual analog scale (VAS), pressure pain thresholds (PPTs) for gastrocnemius, soleus and plantar fascia and weight-bearing lunge test (WBLT) measurements were recorded at baseline and immediately after treatment.Results:Within-group analysis has shown there is a statistically significant difference (p<0.001) in all the outcome measures in both foam roller and self-stretching groups. The between-groups analysis showed no statistical significance difference in VAS, plantar fascia PPT and WBLT parameters (with p-values of 0.171, 0.372 and 0.861, respectively); however, significant differences were found in gastrocnemius PPT (p=0.029) and soleus PPT (p=0.013).Conclusion:It was seen that both stretching and foam rolling techniques helped in reducing pain and increasing the ROM. However, the effectiveness of foam roller was superior to stretching in terms of increase in PPTs at gastrocnemius and soleus.Clinical Trial Registration No:CTRI/2018/01/011398.Name of registry:The Clinical Trials Registry — India (CTRI); https://ctri.nic.in.     

Osteopathic manipulative treatment combined with exercise improves pain and disability in individuals with non-specific chronic neck pain: A pragmatic randomized controlled trial

PurposeTo determine effectiveness of osteopathic manipulative treatment combined with stretching and strengthening exercises in the cervical region on pain and disability in individuals with non-specific chronic neck pain.Methods90 adults with non-specific chronic neck pain were randomized to either exercises group (EG, n = 45) or osteopathic manipulative treatment associated with exercises group (OMT/EG, n = 45). The primary outcomes were obtained by the use of Numeric Pain-Rating Scale (NPRS), Pressure Pain Threshold (PPT) and Neck Disability Index (NDI). Secondary outcomes included range of motion (ROM) for cervical spine rotation, Fear-Avoidance Beliefs Questionnaire Work/Physical Activity (FABQ-W/PA) and Pain-self efficacy at two different moments: baseline and 4 weeks after the first treatment. Techniques and dosages of OMT were selected pragmatically by a registered osteopath. Generalized Estimating Equations model (GEE), complemented by the Least Significant Difference (LSD) and the intention-to-treat analysis, was used to assess the clinical outcomes.ResultsAnalysis with GEE indicated that OMT/EG reduced pain and disability more than the EG alone after 4 weeks of treatment with statistically significant difference (p < 0,05), as well as cervical active rotation was significantly improved (p = 0.03). There were no between-group differences observed in Pressure Pain Threshold (PPT) measure, Fear-Avoidance Beliefs Questionnaire and Pain-self efficacy.ConclusionThe association between OMT and exercises reduces pain and improves functional disability more than only exercise for individuals with non-specific chronic neck pain.     

Effect of Turmacin supplementation on joint discomfort and functional outcome among healthy participants – A randomized placebo-controlled trial

ObjectiveCurcuma longa has been widely used in Ayurveda for its medicinal properties and Turmacin was developed from C. longa as a standardized extract containing turmerosaccharides. In this clinical trial, the effect of Turmacin on knee joint discomfort in healthy adults subjected to strenuous physical activity was evaluated.DesignDouble-blind, triple-arm, parallel-group, randomized placebo-controlled trial.SettingHealthy participants from an urban tertiary care teaching hospital.InterventionHealthy participants were randomized in 1:1:1 ratio to receive either Turmacin 0.5 g/1 g or placebo once daily for 84 days. The participants were subjected to 10-minute strenuous exercise.Outcome measuresTime to initial pain, final pain score on a visual analogue scale, range of movement (ROM) of knee and the force of contractions of muscles around the knee joint.ResultsA total of n = 90 participants were recruited. The mean final pain scores were significantly lower in the Turmacin 1 g and Turmacin 0.5 g when compared with the placebo from day-7 and day-5 onwards respectively. The survival analysis consistently showed a decreased hazard for early onset of pain in both the Turmacin groups. On day-84, the difference in mean ROM between Turmacin 0.5 g and placebo was 4.79 degrees (p = 0.008) and that for Turmacin 1 g and placebo was 2.34 degrees (p = 0.306). The difference in muscle force for isokinetic contractions of the quadriceps at angular velocities of 120 and 180 was significant between Turmacin 0.5 g and placebo (p = 0.002 and p = 0.005 respectively) while that for Turmacin 1 g & Turmacin 0.5 g (p = 0.206 and p = 0.414 respectively) and Turmacin 1 g & Placebo (p = 0.046 and p = 0.037) were not significant. However, in the within group analysis participants in Turmacin 1 g group had better preserved muscle functions than Turmacin 0.5 g group at angular velocities of 120 and 180 when compared with placebo.ConclusionTurmacin (0.5 g and 1 g) was efficacious when compared to placebo in increasing the pain threshold and knee ROM in healthy participants with minor adverse events.     

The effect of isolytic contraction and passive manual stretching on pain and knee range of motion after hip surgery: A prospective, double-blinded, randomized study

Stretching has its impact on both contractile and noncontractile tissues and is the most important rehabilitation technique utilised used to prevent and treat joint stiffness. Passive manual stretch (PMS) and muscle energy technique (MET) are two of the most commonly used techniques. Our study evaluates the effectiveness of isolytic form of MET in gaining knee range of motion (ROM) and decreasing pain in acute knee involvement and comparing it with standard PMS. We used the clinical scenario of knee joint mobilization in patients operated for hip fractures. Fifty-two subjects were alternatively randomized to two groups, isolytic contraction (ILC) group (n = 26) and PMS group (n = 26). In both the PMS and ILC groups, significant improvements in pain score (measured by the visual analog scale) and knee ROM were reported after the treatment period (p < 0.001). The ILC had significantly better improvement in pain score than the PMS group (p = 0.003). The improvement in knee ROM, however, demonstrated no significant between-group difference (p > 0.05). Thus, isolytic form of MET may be a viable method to decrease pain and improve knee ROM in patients who had undergone surgery after a hip fracture.     

Short-Term Effect of Peer Volunteers in Providing Inpatient Rehabilitative Exercises for Patients After Total Knee Arthroplasty

ObjectiveTo investigate the short-term outcomes at discharge of patients who receive additional postoperative rehabilitative exercises by peer volunteers after total knee arthroplasty (TKA).DesignRetrospective cohort study.SettingTertiary teaching hospital.ParticipantsA total of 476 adult patients who had undergone a primary elective unilateral TKA (N=467).InterventionsAn intervention group received a standardized postoperative rehabilitative exercise protocol taught and supervised by peer volunteers in additional to standard physiotherapy (n=309) compared with a control group receiving standard physiotherapy alone (n=167).Main Outcome MeasuresDischarge outcomes were the pain score using the Numeric Rating Scale pain score, passive knee flexion and extension range of motion (ROM), length of hospitalization, ability to perform an unassisted straight leg raise of the operated leg, ambulation distance, ability in independent walking, walking aids required, discharge destination, and adverse events.ResultsOn multivariate analysis, patients in the intervention group had an increased discharge passive knee flexion ROM of 7.89 degrees (95% confidence interval, 5.47-10.33; P<.001). There were no significant differences for the other outcome measures between the intervention and control group.ConclusionsA rehabilitative exercise program by peer volunteers is feasible and safe after TKA in addition to standard physiotherapy and is associated with improved knee flexion ROM on discharge.     

Acute effect of different duration times of application of myofascial release on quadriceps femoris strength: A randomized clinical trial

ObjectivesTo evaluate the effect of Miofascial Release (MFR) on knee extensors strength, at different duration times of application.Method51 healthy individuals were randomly assigned to one of three groups (3min, 5min or placebo) in this randomized clinical trial. The knee extensors strength was assessed in two conditions: pre and post-intervention, using an isokinetic dynamometer, at speeds of 60° and 120°/s. MFR was applied on the anterior surface of the thigh for 3min or 5 min, according to the experimental groups. The placebo group underwent through the application of a non-therapeutic gel, associated with 3min of a light touch on the skin. Peak torque, total work and mean power were the isokinetic variables analyzed through a multivariate analysis of variance (MANOVA) with p ≤ 0.05.ResultsOur findings suggest a main effect and interaction between moments (pre and post-intervention) and speeds (60° and 120°/s) for total work and mean power (p < 0.01). Likewise, main effect and interaction of speed were observed for peak torque (p < 0.01). There were no significant differences for the other analyzed variables.ConclusionNo significant main effect of MFR were detected in any of the proposed application time on peak torque, total work and mean power, in the knee extensors, compared to the placebo group.
