Effect of botulinum toxin type a combined with physical therapy on functional capacity in children with spastic cerebral palsy: a randomized controlled clinical trial.

OBJECTIVE: Investigate the effects of botulinum toxin type A (BoNT-A) combined with physical therapy on functional capacity in children with spastic cerebral palsy (CP). METHODS: Twenty-four children with spastic CP were treated with either BoNT-A and physical therapy or physical therapy alone. RESULTS: Significant differences (p < 0.05) were found after 30 days of treatment for the Berg Scale, Timed Up and Go (TUG) test, Ashworth Scale and Pediatric Evaluation of Disability Inventory (PEDI) and after three months for the Berg Scale, TUG test and PEDI. No significant differences (p > 0.05) were found in the control group. DISCUSSION: BoNT-A combined with physical therapy leads to significant improvements in spasticity and functionality in children with CP within a period of three months from the onset of treatment.

Correlation Among Pain Intensity, Catastrophizing, and Falls in Older Individuals With Unilateral Knee Osteoarthritis: A Cross-Sectional Study.

OBJECTIVE: The purpose of this study was to investigate whether pain intensity and catastrophizing are associated with fear of falls and the number of falls in older persons with knee osteoarthritis (OA). METHODS: A cross-sectional study was conducted involving 100 volunteers (male and female participants), 60 to 80 years old, with a diagnosis of knee OA. Patients were recruited from a physical therapy clinic in the city of São Paulo, Brazil, from March 2019 to November 2019. The following measures were used for the evaluations: Numerical Rating Pain Scale (NRPS), Pain-Related Self-Statement Scale (PRSS), and Falls Efficacy Scale. In statistical analysis, histograms were created to determine the distribution of data. Spearman's correlation coefficients (rs) were then calculated to determine the strength of the associations among the variables. The receiver operating characteristic curve was used to identify the accuracy of PRSS and NRPS in differentiating participants with a history of falls from those without. RESULTS: No significant correlation was found among the pain intensity, pain catastrophizing, fear of falling, and number of falls (rs value ranging from -0.033 to -0.167; P value ranging from .096-.743). The accuracy of PRSS and NRPS in differentiating participants with falls from those without was insufficient, with area under the curve values of 0.46 and 0.42, respectively. CONCLUSION: Pain catastrophizing and intensity were not significantly associated with fear of falling and numbers of falls in older individuals with unilateral knee OA.

Prevalence of signs and symptoms of temporomandibular disorder in the metropolitan region of Rio De Janeiro: A population-based cross-sectional study.

OBJECTIVE: Temporomandibular disorder (TMD) is a group of heterogeneous pathological conditions that affect the temporomandibular joint (TMJ), mastication muscles, and some associated structures. The aim of this study was to measure the prevalence of signs and symptoms of dysfunction, including knowledge of TMD in a stratum of the population. METHODS: A population extract from Rio de Janeiro subdivided by conglomerates was interviewed through an online form. RESULTS: The results showed that only 19% of the participants had no symptoms related to TMD. CONCLUSION: The results showed that the symptom prevalence is directly related to knowledge and practices about the disorder and that its presence may be under-reported.

Ratio between maximum jaw opening and lateral excursion in brazilians with and without temporomandibular disorder / Razão entre abertura máxima e excursão lateral mandibular em brasileiros com e sem disfunção temporomandibular

Background: Mandibular movements (MM) can offer important information regarding temporomandibular joint health. Objective: Evaluate MM and the ratio between maximum jaw opening and mandibular lateral excursion in Brazilians with and without temporomandibular disorder (TMD). Methods: A cross-sectional study was conducted with 801 individuals between five and 80 years. All individuals answered a screening questionnaire; and MM were measured using digital calipers. The Mann-Whitney test was used to compare the differences between the sexes and groups with and without TMD. The Kruskal-Wallis test was used to determine differences in MM among age groups. Results: MM were smaller in individuals with TMD than in those without TMD. The ratio between jaw opening and lateral excursion was 5.23 in women without TMD and 5.59 in women with TMD. In males, the ratio was 4.75 and 5.52 in individuals without and with TMD, respectively. Conclusion: MM are smaller in Brazilians with TMD, whereas the ratio between jaw opening and lateral excursion is larger.

Conclusão: Os MM são menores em brasileiros com DTM, enquanto que a relação entre abertura mandibular e excursão lateral é maior.

Association of photobiomodulation therapy and therapeutic exercises in relation to pain intensity and neck disability in individuals with chronic neck pain: a systematic review of randomized trials.

Exercise is often pointed out as an effective form of treatment in the clinical management of chronic neck pain (CNP). However, due to its complex range of causal factors and great diversity of signs and symptoms, other resources such as photobiomodulation therapy (PBMT) have been routinely used for the treatment of CNP. The aim of this study was to systematically review the literature on the use of the association of PBMT and therapeutic exercises in relation to pain intensity and neck disability in individuals with CNP. PubMed, Medline (via Ovid), Embase (via Ovid), Cinahl (via Ebsco), and Central (via Cochrane library) databases were searched using the following terms: "laser," "low-level laser," "photobiomodulation," "light emitting diodes," "phototherapy," "exercise," "chronic neck pain." After verification and implementation of eligibility criteria, seven manuscripts were considered eligible for data analysis. These manuscripts had methodological quality between 5 and 8 points on the PEDro scale. Most studies used low infrared laser therapy to perform PBMT, with a wide range of parameters and energy density between 2 and 7 J/cm2 and a total treatment time between 2 and 6 weeks. Four studies showed significant benefits in terms of pain intensity at short-term follow-up and one at intermediate-term follow-up. However, only one showed a minimal clinically important change. No studies have shown significant improvement in disability. This review demonstrates that the association of PBMT with therapeutic exercises in general promotes significant benefits only for the intensity of pain. However, it does not seem to promote a minimally effective clinical difference in individuals with CNP.

Correlation between tactile acuity, pain intensity, and functional capacity in individuals with chronic neck pain.

OBJECTIVE: The aim of this study was to verify the correlation between tactile acuity, intensity of pain at rest, and movement and functional capacity in individuals with chronic neck pain. METHODS: This was a cross-sectional study composed of two groups: individuals with chronic neck pain and individuals without neck pain. Evaluations were performed using the Numerical Rating Pain Scale at rest and movement, Neck Disability Index, and two-point discrimination test. RESULTS: The final sample consisted of 100 volunteers, 50 in each group. The groups did not show significant differences (p>0.05) in personal characteristics. It was observed that volunteers with cervical pain presented alterations in tactile care, with a significant and clinical increase in the perceived distance (Median 6.66; 95%CI 6.29-7.02; Cohen's d 7.22; 95%CI 6.15-8.30), and yet, positive, moderate, and significant correlation between two-point discrimination test, intensity of pain at rest and movement, and neck disability index (r=0.778-0.789, p<0.05). CONCLUSION: Tactile acuity is associated with pain intensity at rest and movement and functional capacity in individuals with chronic neck pain.

Photobiomodulation on trigeminal neuralgia: systematic review.

Trigeminal neuralgia is a recurrent episode of facial pain, that may be associated with other conditions such as multiple sclerosis, neoplasms, and nerve compromises or may occur due to an unknown cause. The available treatments are pharmacotherapy or surgery; however, both are susceptible to develop side effects. Photobiomodulation could be a promising alternative therapy for trigeminal neuralgia. A systematic review of literature was carried out using the PRISMA protocol, in the PubMed/MEDLINE, Embase, and Web of Science databases. Risk of bias by ROB 2.0 protocol was performed in included studies. Initially, 20 identified articles were collected varying between the years of 1983-2018, from which 6 were included. A total of 193 patients were evaluated; photobiomodulation was compared to conventional therapies, TENS, and therapy combinations with pharmacotherapy. The overall risk of bias was low, with some concerns in the randomization and double-blinding process; moreover, there are few reports in the literature. Photobiomodulation appears to be as effective as conventional therapies, being a coadjutant therapeutic opportunity for the treatment of trigeminal neuralgia.

The Effect of Sodium Bicarbonate Supplementation on Electromyographic Muscle Activity in Healthy, Physically Active Individuals: A Systematic Review.

AIM: The aim of this systematic review was to investigate the effects of sodium bicarbonate supplementation on electromyographic (EMG) muscle activity in healthy, physically active individuals. METHODS: A systematic review of cross-sectional studies, crossover studies and randomized controlled trials was performed to investigate the effects of sodium bicarbonate supplementation on EMG muscle activity in healthy, physically active individuals. Potentially eligible for the systematic review were identified through searches conducted in the PubMed/MEDLINE, Science Direct and Scopus, considering publications from January 1980 to August 2019. The terms used in the search were: sodium bicarbonate, NaHCO3, alkalosis, alkaloses, electromyography, surface electromyography, electromyographies, electromyogram and EMG. Two independent assessors extracted data from the selected articles. Bias analysis was conducted using the Cochrane Risk of Bias tool and methodological quality was appraised using a checklist created based on the guidelines of the Consolidated Standards of Reporting Trials and the International Society of Electrophysiology and Kinesiology. RESULTS: A total of 67 studies were retrieved and seven were included in this review. Only two studies showed significant differences in muscle activity after sodium bicarbonate supplementation. The different EMG signal capturing, processing, and analysis methods used constitute an important limitation to the comparative analyses of the results reported in the studies selected for the present review. CONCLUSION: The results found do not allow us to affirm whether EMG may or may not be a safe tool to assess the effects of sodium bicarbonate supplementation on muscle activity.

Association between convergence insufficiency and temporomandibular disorder cross-sectional study.

OBJECTIVES: Evaluate whether there is an association between convergence insufficiency and temporomandibular disorder (TMD) and whether there is an association between pain and range of motion in different degrees of TMD. METHODS: We evaluated 138 individuals with TMD and 46 without TMD using the Research Diagnostic Criteria for temporomandibular disorders, the Fonseca Anamnestic Index (FAI), Numeric Pain Rating Scale, and the measurement of mandibular range of motion (ROM). Convergence insufficiency was diagnosed using the convergence test and Convergence Insufficiency Symptom Survey. Analysis of variance was used to compare age and mandibular ROM. The Kruskal-Wallis was used to compare mandibular ROM and pain between groups. The chi-square test was used to evaluate associations between TMD subgroups and the FAI, sex, and ocular convergence. RESULTS: The majority of individuals without TMD did not exhibit convergence insufficiency. The frequency convergence insufficiency was significantly higher among individuals with severe TMD (p < 0.003). Mean pain severity differed between individuals with and without TMD. Mandibular ROM diminished with the increase in TMD severity. CONCLUSIONS: Convergence insufficiency, age, the increase in pain, and the reduction in mandibular range of motion were associated with the degrees of TMD severity. Despite the significant associations between convergence insufficiency and both pain and TMD severity, these variables cannot be indicated as predictive factors due to the low variability in the linear regression analysis. CLINICAL RELEVANCE: The present findings can assist in decision making regarding the treatment of severe TMD and the evaluation of ocular convergence.

Correlation of pain sensitization with muscle strength and angular kinematics in women with patellofemoral pain.

BACKGROUND: Patellofemoral pain has a poor long-term prognosis, which can be explained by a pain sensitization process. The pain sensitization process may be related to the increase of stress in the patellofemoral joint that is already associated with kinematic alterations and weakness in the musculature of the hip and knee. METHODS: Were compared the pressure pain threshold, temporal summation, conditioned pain modulation, angular kinematics, and muscle strength between 26 patellofemoral pain and 24 asymptomatic women and then correlated pain sensitization variables with biomechanical variables in pain group. The pressure pain threshold was determined on seven points of the knee, tibialis anterior muscle, and elbow. Ten consecutive stimuli were performed for temporal summation, and cold water was used as the conditioning stimulus for conditioned pain modulation. The strength of hip and knee muscles was determined using a manual dynamometer. Three-dimensional kinematics were evaluated during the lateral step down, considering peak and excursion values of the movement and the Movement Deviation Profile. FINDINGS: The pressure pain threshold of the elbow (2.13 [1.84-2.41] vs. 1.63 [1.25-2] kg/cm2), all sites of the knee were lower, as well as the Movement Deviation Profile was higher (9.33 [9.20-9.46] vs. 12.43 [12.1-12.75]) in the pain group. No difference in temporal summation, conditioned pain modulation, muscle strength and discrete kinematic values were found. No significant correlation was found between the Movement Deviation Profile and pressure pain threshold. INTERPRETATION: Biomechanical factors, pain processing, and modulation in women with patellofemoral pain, when different from asymptomatic individuals, are not necessarily associated.

Objetivo: Comparar clinicamente os pacientes com desordens buco-maxilo-faciais (DBMF) atendidos em uma clínica-escola de fisioterapia da cidade de Fortaleza. Materiais e métodos: Dentre 5.357 prontuários, foram coletados os dados de 315 prontuários referentes aos pacientes acometidos por DBMF, dentre eles, 62 homens e 253 mulheres. Resultados: O estudo adotou perfil predominante de pacientes do gênero feminino, solteiros, entre 21 a 30 anos, estudantes, que fizeram uso de relaxante muscular; mulheres sentiram dor irradiada, já homens, dor do tipo fina. Bruxismo/endentações/desgaste dentário foram prevalentes em ambos os sexos e os sintomas que apresentaram diferença estatística entre homens e mulheres foram cervicalgia (p=0,0051), cefaleia (p<0,0001), formigamento de membros superiores (p=0,0371) e dor corporal (p=0,0234). Conclusão: Bruxismo/endentações/desgaste dentário foram os prevalentes em ambos os sexos. Entre os homens, o sintoma mais prevalente foi a dor ou cansaço ao mastigar, já entre as mulheres foi a cefaleia.

Exercise program combined with electrophysical modalities in subjects with knee osteoarthritis: a randomised, placebo-controlled clinical trial.

BACKGROUND: It is not yet clear which of the various electrophysical modalities used in clinical practice is the one that contributes most positively when added to an exercise program in patients with knee osteoarthritis (OA). The aim of the present study was to analyze the clinical effects of the inclusion of interferential current therapy (ICT), shortwave diathermy therapy (SDT) and photobiomodulation (PHOTO) into an exercise program in patients with knee OA. METHODS: This prospective, five-arm, randomised, placebo-controlled trial was carried out with blinded participants and examiners. We recruited 100 volunteers aged 40 to 80 years with knee OA. Participants were allocated into five groups: exercise, exercise + placebo, exercise + ICT, exercise + SDT, and exercise + PHOTO. The outcome measures included Western Ontario and McMaster Universities (WOMAC), numerical rating pain scale (NRPS), pressure pain threshold (PPT), self-perceived fatigue and sit-to-stand test (STST), which were evaluated before and after 24 treatment sessions at a frequency of three sessions per week. RESULTS: In all groups, there was a significant improvement (p < 0.05) in all variables over time, except pressure pain threshold. We observed significant differences (p < 0.05) between the groups for WOMAC function (exercise vs. exercise + placebo, mean difference [MD] = 5.55, 95% confidence interval [CI] = 3.63 to 7.46; exercise vs. exercise + ICT, MD = 3.40, 95% CI = 1.46 to 5.33; exercise vs. exercise + SDT, MD = 4.75, 95% CI = 1.85 to 7.64; exercise vs. exercise + PHOTO, MD = 5.45, 95% CI = 3.12 to 7.77) and WOMAC pain, with better scores achieved by the exercise group. However, these differences were not clinically relevant when considering the minimum clinically important difference. CONCLUSION: The addition of ICT, SDT or PHOTO into an exercise program for individuals with knee OA is not superior to exercise performed in isolation in terms of clinical benefit. clinicaltrials.gov: NCT02636764, registered on March 29, 2014.

International consensus on the most useful assessments used by physical therapists to evaluate patients with temporomandibular disorders: A Delphi study.

OBJECTIVE: To identify assessment tools used to evaluate patients with temporomandibular disorders (TMD) considered to be clinically most useful by a panel of international experts in TMD physical therapy (PT). METHODS: A Delphi survey method administered to a panel of international experts in TMD PT was conducted over three rounds from October 2017 to June 2018. The initial contact was made by email. Participation was voluntary. An e-survey, according to the Checklist for Reporting Results of Internet E-Surveys (CHERRIES), was posted using SurveyMonkey for each round. Percentages of responses were analysed for each question from each round of the Delphi survey administrations. RESULTS: Twenty-three experts (completion rate: 23/25) completed all three rounds of the survey for three clinical test categories: 1) questionnaires, 2) pain screening tools and 3) physical examination tests. The following was the consensus-based decision regarding the identification of the clinically most useful assessments. (1) Four of 9 questionnaires were identified: Jaw Functional Limitation (JFL-8), Mandibular Function Impairment Questionnaire (MFIQ), Tampa Scale for Kinesiophobia for Temporomandibular disorders (TSK/TMD) and the neck disability index (NDI). (2) Three of 8 identified pain screening tests: visual analog scale (VAS), numeric pain rating scale (NRS) and pain during mandibular movements. (3) Eight of 18 identified physical examination tests: physiological temporomandibular joint (TMJ) movements, trigger point (TrP) palpation of the masticatory muscles, TrP palpation away from the masticatory system, accessory movements, articular palpation, noise detection during movement, manual screening of the cervical spine and the Neck Flexor Muscle Endurance Test. CONCLUSION: After three rounds in this Delphi survey, the results of the most used assessment tools by TMD PT experts were established. They proved to be founded on test construct, test psychometric properties (reliability/validity) and expert preference for test clusters. A concordance with the screening tools of the diagnostic criteria of TMD consortium was noted. Findings may be used to guide policymaking purposes and future diagnostic research.

Is there a difference in the electromyographic activity of the masticatory muscles between individuals with temporomandibular disorder and healthy controls? A systematic review with meta-analysis.

The diagnosis of temporomandibular disorders (TMD) is complex, and it is not yet clear in the literature whether the clinical changes associated with these disorders are also reflected in the electromyographic (EMG) activity of the muscles of mastication. To determine whether there is a difference in the electromyographic activity of the masticatory muscles between individuals with TMD and healthy controls. ScienceDirect, EMBASE, MEDLINE, PEDro, SciELO, CINAHL and LILACS databases from January 2000 to February 2019. Cross-sectional studies, crossover studies and randomised controlled trials evaluating EMG activity of right and left masseter and anterior temporal muscles in patients with TMD and healthy controls. Two independent assessors extracted data from the selected articles. The risk of bias was determined using a checklist for assessing methodological quality created based on the guidelines of the Strengthening the Reporting of Observational Studies in Epidemiology and International Society of Electrophysiology and Kinesiology. Mean differences and 95% confidence intervals were calculated and combined in meta-analyses. A total of 51 267 studies were retrieved, and 12 were included in this review. Only two studies enabled the comparative analysis of the results. The different EMG signal capturing, processing and analysis methods used constitute an important limitation to the comparative analyses of the results reported in the studies selected for the present review. This systematic review did not demonstrate evidence of significant differences in the EMG activity of the masticatory muscles between individuals with TMD and healthy controls.

Intraoral photobiomodulation diminishes pain and improves functioning in women with temporomandibular disorder: a randomized, sham-controlled, double-blind clinical trial : Intraoral photobiomodulation diminishes pain in women with temporomandibular disorder.

The aim of the present study was to evaluate the effect of intraoral photobiomodulation involving super-pulsed laser (905 nm) combined with red (640 nm) and infrared (875 nm) light-emitting diodes on pain, mandibular range of motion, and functioning in women with myogenous temporomandibular disorder. A randomized, sham-controlled, double-blind clinical trial was conducted involving 30 women with myogenous temporomandibular disorder diagnosed using the Research Diagnostic Criteria for Temporomandibular Disorders. The participants were randomly allocated to two groups (active and sham photobiomodulation). The evaluations involved this use of the visual analog scale, digital calipers, and a functional scale. Photobiomodulation was administered intraorally in the region of the pterygoid muscles, bilaterally, in all participants for a total of six sessions. Evaluations were performed on five occasions: prior to the intervention, immediately after the first session, 24 h and 48 h after the first session, and after the six sessions. Significant differences between groups were found regarding pain (p ≤ 0.01) and functioning (p ≤ 0.04). However, no statistically significant difference was found regarding range of mandibular motion. The findings demonstrate that intraoral photobiomodulation involving super-pulsed laser (905 nm) combined with red (640 nm) and infrared (875 nm) light-emitting diodes diminishes pain and improves functioning but does not exert an influence on mandibular range of motion in women with temporomandibular disorder.Trial registration: NCT02839967.

Visceral Manipulation Decreases Pain, Increases Cervical Mobility and Electromyographic Activity of the Upper Trapezius Muscle in Non-Specific Neck Pain Subjects with Functional Dyspepsia: Two Case Reports.

BACKGROUND AND PURPOSE: The lack of clear knowledge about the etiology of nonspecific neck pain (NS-NP) strengthens the need for other mechanisms, still poorly described in the literature, to be investigated. Therefore, a quantitative analysis of two cases of NS-NP in subjects with functiona dyspepsia was conducted in order to verify the immediate and seven-day postintervention effects of visceral manipulation (VM) to the stomach and liver on neck pain, cervical range of motion (ROM), and electromyographic (EMG) activity of the upper trapezius muscle. CASE DESCRIPTION: Case A was an 18-year-old female with a complaint of nonspecific neck pain for one year, with reported pain on waking, momentary intermittent pain, and occasional symptoms of paresthesia in the upper limbs. Case B was a 25-year-old female with a complaint of cervical pain for one year, accompanied by pain in the unilateral temporomandibular joint, and medial thoracic region. Both cases presented functional dyspepsia. OUTCOMES: The results demonstrated (subjects A and B, respectively) a general increase in cervical ROM (range: 12.5% to 44.44%) and amplitude of the EMG signal (immediately postintervention: 57.62 and 20.78; post seven days: 53.54% and 18.83%), and an increase in muscle fiber conduction velocity immediately postintervention (4.44% and 7.44%) and a decrease seven days postintervention (25.25% and 21.18%). For pain, a decrease was observed immediately postintervention (23.07% and 76.92%) and seven days postintervention (100% for both subjects). DISCUSSION: A single VM provided important clinical improvement in neck pain, cervical spine range of motion, and EMG activity of the upper trapezius muscle, immediately and seven days postintervention in two NS-NP subjects with functional dyspepsia.

Biofeedback for pelvic floor muscle training in women with stress urinary incontinence: a systematic review with meta-analysis.

BACKGROUND: Several clinical effects have been attributed to the use of biofeedback (BF) as an adjuvant in the treatment of women with stress urinary incontinence (SUI). OBJECTIVES: To determine whether BF is more effective than other interventions for women with SUI in terms of quantification of urine leakage, episodes of urinary loss, quality of life and muscle strength. DATA SOURCES: Science Direct, Embase, MEDLINE, Pedro, SciELO, CINAHL and LILACS from January 2000 to February 2017. STUDY SELECTION: Randomised controlled trials (RCTs) addressing the effects of pelvic muscle floor training (PFMT) with BF for the conservative treatment of women with SUI. DATA EXTRACTION AND DATA SYNTHESIS: Two independent assessors extracted data from articles. The risk of bias for individual studies was assessed using the Jadad scale and Physiotherapy Evidence Database (PEDro) scale. Mean differences (MD) and 95% confidence intervals were calculated and combined in meta-analyses. RESULTS: In total, 1194 studies were retrieved and 11 were included in this review. Only two RCTs demonstrated a low risk of bias according to the PEDro scale. The results demonstrated that PFMT with BF was no better than alternative interventions in terms of muscle strength measured using a perineometer. LIMITATIONS: Low methodological quality of studies, heterogeneity of outcomes, and differences in implementation of intervention protocols and BF modalities. CONCLUSIONS: PFMT with BF does not offer therapeutic benefits over alternative interventions (no training, PFMT alone and vaginal electrical stimulation) for the treatment of female SUI.

Age-Related Changes in Postural Control in Physically Inactive Older Women.

BACKGROUND AND PURPOSE: The maintenance of postural control is influenced by the complexity of a given task. Tasks that require greater attention and cognitive involvement increase the risk of falls among older adults. The aim of the present study was to evaluate the adaptation of the postural control system to different levels of task complexity in physically inactive young and older women. METHODS: A cross-sectional study was conducted with adult women classified as physically inactive based on the results of the International Physical Activity Questionnaire. The participants were 27 young (20-30 years of age) and 27 older (60-80 years of age) women. Sway velocity of the center of pressure in the anterior-posterior and medial-lateral directions was calculated using a force plate under 6 conditions: standing directly on the force plate or on a foam placed over the force plate, eyes open or closed, and dual-task complexity with and without the foam. RESULTS AND DISCUSSION: A 2-way analysis of variance revealed that sway velocity increased in both groups when the task conditions were altered. The older women exhibited significantly greater sway velocity compared with the young women on all tasks. However, the patterns of postural control adaptation to the different levels of complexity were similar among all participants. CONCLUSIONS: In this study, the adaption of the postural control system to different levels of task complexity did not differ between physically inactive young and physically inactive older women. However, the physically inactive older women exhibited greater sway velocity compared with the young women.
