Effects of passive upper extremity joint mobilization on pain sensitivity and function in participants with secondary carpometacarpal osteoarthritis: a case series

Effectiveness of manual therapy in patients with thumb carpometacarpal osteoarthritis: a systematic review and meta-analysis

Background: The effectiveness of Manual Therapy (MT) in thumb carpometacarpal osteoarthritis (OA) is unclear.Objective: This study aimed to determine the effectiveness of MT for functional outcomes in patients with thumb carpometacarpal OA. Design: Systematic review and meta-analysis of randomized clinical trials. Methods: An electronic search was performed in the Medline, Central, Embase, PEDro, Lilacs, Cinahl, SPORTDiscus, and Web of Science databases. The eligibility criteria for selecting studies included randomized clinical trials that compared MT versus other interventions in functional outcomes, such as thumb and/or hand function questionnaires, pinch and/or grip strength, thumb and/or hand range of motion, and pain intensity or pressure pain threshold in patients with thumb carpometacarpal OA. Results: Five clinical trials met the eligibility criteria; for the quantitative synthesis, four studies were included. The mean difference (MD) for grip strength was 0.87kg (95% CI = 0.29-1.44, p = .003), for pinch strength was 0.10kg (95% CI = -0.01-0.20, p = .06), and for the pressure pain threshold was 0.64kg/cm² (95% CI = 0.07-1.20, p = .03). All differences were in favor of the MT group. Conclusions: In the short-term, there was moderate to high evidence, with statistically significant differences in the functional outcomes, in favor of MT versus sham interventions in patients with thumb carpometacarpal OA. However, these differences are not clinically important.

Changes in glenohumeral translation, electromyographic activity, and pressure-pain thresholds following sustained or oscillatory mobilizations in stiff and healthy shoulders: Results of a randomized, controlled laboratory trial

STUDY DESIGN

Randomized Controlled Laboratory Study.

BACKGROUND

Posterior glide glenohumeral (GH) mobilizations are utilized to improve motion and decrease pain in patients with shoulder pathologies, thought to be due to capsular stretch and neurophysiologic effects. However, it remains unclear how different GH mobilizations influence mobility, rotator cuff (RC) activity, and pain processing, or if effects are different in stiff (≥15-degree loss of passive motion in any plane) rather than healthy shoulders.

OBJECTIVES

To compare the effects of oscillatory and sustained posterior GH mobilizations on translation, RC activity, and pressure pain threshold (PPT) in stiff and healthy shoulders.

METHODS

Eighty-eight participants, (44 control, 44 stiff shoulders) were randomly assigned to one of two mobilization conditions. Pre-post intervention measurements of PPT, GH translation via ultrasound imaging, and RC activity assessed via electromyography were performed. Sustained or oscillatory grade III posterior GH mobilizations were then provided to all participants. Data were analyzed using tests of difference and regression modeling.

RESULTS

Sustained glides (2.8 ± 3.3 mm) demonstrated significantly greater changes in translation compared to oscillatory glides (1.1 ± 3.9 mm), p = .028. Stiff shoulders demonstrated higher total RC activity than controls both pre (+24.51%, p = .004) and post-intervention (+23.10%, p = .01). Small changes in PPT occurred across all conditions, none reaching clinically meaningful levels.

CONCLUSION

Sustained mobilizations resulted in greater changes in GH translation. RC activity was higher in the stiff shoulder group, and remained higher post-intervention despite gains in GH translation, suggesting a mechanical rather than neurophysiologic effect. There was no meaningful difference in PPT between modes of mobilization.

Human adipose-derived Mesenchymal stem cells, low-intensity pulsed ultrasound, or their combination for the treatment of knee osteoarthritis: study protocol for a first-in-man randomized controlled trial

Background

Human adipose-derived Mesenchymal stem cells (HADMSCs) have proven their efficacy in treating osteoarthritis (OA), in earlier preclinical and clinical studies. As the tissue repairers are under the control of mechanical and biochemical signals, improving regeneration outcomes using such signals has of late been the focus of attention. Among mechanical stimuli, low-intensity pulsed ultrasound (LIPUS) has recently shown promise both in vitro and in vivo. This study will investigate the potential of LIPUS in enhancing the regeneration process of an osteoarthritic knee joint.

Methods

This study involves a prospective, randomized, placebo-controlled, and single-blind trial based on the SPIRIT guidelines, and aims to recruit 96 patients initially diagnosed with knee osteoarthritis, following American College of Rheumatology criteria. Patients will be randomized in a 1:1:1 ratio to receive Intraarticular HADMSCs injection with LIPUS, Intraarticular HADMSCs injection with shame LIPUS, or Normal saline with LIPUS. The primary outcome is Western Ontario and McMaster Universities Index of OA (WOMAC) score, while the secondary outcomes will be other knee structural changes, and lower limb muscle strength such as the knee cartilage thickness measured by MRI. Blinded assessments will be performed at baseline (1 month prior to treatment), 1 month, 3 months, and 6 months following the interventions.

Discussion

This trial will be the first clinical study to comprehensively investigate the safety and efficacy of LIPUS on stem cell therapy in OA patients. The results may provide evidence of the effectiveness of LIPUS in improving stem cell therapy and deliver valuable information for the design of subsequent trials.

Necessity of Immobilizing the Metacarpophalangeal Joint in Carpometacarpal Osteoarthritis: Short-term Effect

BACKGROUND

Conservative treatment for carpometacarpal (CMC) joint osteoarthritis (OA) may include orthotic fabrication to decrease pain. Different types of orthoses have been used as conservative interventions to improve symptoms, but there are no guidelines specifying if inclusion of the thumb metacarpophalangeal (MCP) in an orthosis is required in the treatment of thumb CMC joint OA. The main objective of this study is to determine the effectiveness of 2 different thumb CMC joint orthotic designs on pain reduction and improved hand function: one design immobilizes both the MCP joint and the CMC joint and the other design immobilizes only the CMC joint.

METHODS

A total of 66 patients were included in the study. One group of 33 patients received a short thumb orthosis with the MCP joint excluded, and the other group of 33 patients received a short thumb orthosis with the MCP joint included. Outcomes measures included the visual analog scale for pain and the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH; Spanish version) for function.

RESULTS

In both patient groups, the orthoses contributed to decreased pain levels and improved functional abilities ( F_1.0 = 315.467 and F_1.0 = 72.419; both, P < .001). There was no significant difference between the 2 groups regarding pain or improvement in daily activities ( F_1.0 = 0.553 and F_1.0 = 2.539; both, P > .05).

CONCLUSION

There are benefits of either thumb orthotic design on pain reduction and functional improvement even after 1 week of using the orthoses as the sole conservative treatment.

Efficacy of Short-Term Robot-Assisted Rehabilitation in Patients With Hand Paralysis After Stroke: A Randomized Clinical Trial

BACKGROUND

We evaluated the effectiveness of robot-assisted motion and activity in additional to physiotherapy (PT) and occupational therapy (OT) on stroke patients with hand paralysis.

METHODS

A randomized controlled trial was conducted. Thirty-two patients, 34.4% female (mean ± SD age: 68.9 ± 11.6 years), with hand paralysis after stroke participated. The experimental group received 30 minutes of passive mobilization of the hand through the robotic device Gloreha (Brescia, Italy), and the control group received an additional 30 minutes of PT and OT for 3 consecutive weeks (3 d/wk) in addition to traditional rehabilitation. Outcomes included the National Institutes of Health Stroke Scale (NIHSS), Modified Ashworth Scale, Barthel Index (BI), Motricity Index (MI), short version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH), and the visual analog scale (VAS) measurements. All measures were collected at baseline and end of the intervention (3 weeks).

RESULTS

A significant effect of time interaction existed for NIHSS, BI, MI, and QuickDASH, after stroke immediately after the interventions (all, P < .001). The experimental group had a greater reduction in pain compared with the control group at the end of the intervention, a reduction of 11.3 mm compared with 3.7 mm, using the 100-mm VAS scale.

CONCLUSIONS

In the treatment of pain and spasticity in hand paralysis after stroke, robot-assisted mobilization performed in conjunction with traditional PT and OT is as effective as traditional rehabilitation.

Contralateral sensory and motor effects of unilateral kaltenborn mobilization in patients with thumb carpometacarpal osteoarthritis: a secondary analysis

[Purpose] The aim of this study was to determine changes in pressure sensitivity and pinch strength in patients with thumb carpometacarpal (CMC) osteoarthritis (OA) in the contralateral hand after unilateral Kaltenborn mobilization on the symptomatic hand. [Subjects and Methods] Twenty-nine females with dominant hand thumb CMC osteoarthritis participated (age 70–90), and were randomized into 2 groups. The experimental group received a Kaltenborn mobilization, and the placebo group received a nontherapeutic dose of intermittent ultrasound. Pressure pain thresholds (PPT) at the thumb CMC joint, scaphoid bone and hamate bone and tip and tripod pinch strength were assessed before and after the intervention and 1 week (1st follow-up) and 2 weeks (2nd follow-up) after the intervention. [Results] Significant increases in PPT in the experimental group at all follow-up periods as compared with baseline data were found. The post-intervention between-group mean differences for PPT were 1.1 (95%CI 0.4–1.8) for the CMC joint, 1.1 (95%CI 0.2–2.1) for the scaphoid, and 1.5 (95%CI 0.5–2.8) for the hamate. The post-intervention between-group mean differences were 0.5 (95%CI 0.2–0.9) for the tip pinch and 0.3 (95%CI 0.1–0.6) for the tripod pinch. [Conclusion] The current secondary analysis found that Kaltenborn mobilization for the symptomatic hand reduces pressure pain sensitivity (PPT increases) and also produces motor changes in the contralateral non-treated hand compared with a placebo group.

Management of trapeziometacarpal osteoarthritis pain and dysfunction using mobilization with movement technique in combination with kinesiology tape: a case report

OBJECTIVE

The purpose of this report is to describe the management of a patient with advanced trapeziometacarpal (TMC) osteoarthritis (OA) using mobilization with movement technique in combination with kinesiology tape to decrease pain and improve range of motion.

CLINICAL FEATURES

A 52-year-old female seamstress (a career of 35 years' duration) presented to a physiotherapy clinic with pain in the dorsal aspect of the thumb carpometacarpal region of the right (dominant) hand. Examination revealed reduced ability to abduct the right thumb, significant loss of web space, weakness of pinch grip, and deterioration of hand function. Radiographs demonstrated OA of the TMC stage IV according to the Eaton-Littler-Burton classification, with instability and subluxation of the joint.

INTERVENTION AND OUTCOME

A combined treatment protocol of mobilization with movement and kinesiology tape at the TMC joint for 12 weekly sessions was performed. Outcome measures were assessed at baseline, immediately upon completion of treatment, and at 2-month follow-up and included numeric pain rating scale, range of motion, pressure pain threshold, and tip pinch strength at the TMC joint. Treatment interventions were applied for 12 sessions over a period of 2 months. Outcome measures indicated significant reduction of the patient's subjective pain reports and considerable improvement in functional and occupational tasks. A follow-up visit at 4 months (2 months after last treatment) showed that the improvement was maintained.

CONCLUSION

A combined program of mobilization with movement and kinesiology tape reduced pain, increased range of motion, and increased tip pinch strength in a patient with severe functional impairment related to dominant TMC OA.

Widespread pressure pain hypersensitivity in elderly subjects with unilateral thumb carpometacarpal osteoarthritis

BACKGROUND

Widespread pressure hypersensitivity is one of the signs that characterize central pain sensitization in subjects with knee and hip osteoarthritis (OA). The purpose of this study was to evaluate whether widespread pressure pain hyperalgesia is a feature of individuals with unilateral symptomatic thumb carpometacarpal (CMC) OA.

METHODS

A total of 16 patients with unilateral symptomatic thumb CMC OA and 16 healthy sex- and age-matched controls were recruited. Pressure pain thresholds (PPTs) were assessed bilaterally over the first CMC joint; the C5-C6 zygapophyseal joint; the median, ulnar, and radial nerves; and tibialis anterior muscle. Grip and key strength, intensity of pain, and function QuickDASH were also measured.

RESULTS

The analyses showed that patients with thumb CMC OA present bilaterally decreased PPTs over the first CMC joint, the C5-C6 zygapophyseal joint, and the tibialis anterior, median, ulnar and radial nerve as compared to controls (all, P < 0.01). Patients with thumb CMC OA also exhibited a bilateral reduction in pinch and grip strength than controls (P < 0.05). A significant correlation was found between PPT over the radial nerve and QuickDASH (r = 0.546, P = 0.029).

CONCLUSION

This study revealed bilateral widespread pressure pain hypersensitivity in individuals with unilateral symptomatic thumb CMC OA, suggesting that central pain processing mechanisms might be a feature of this pain population. These results should be taken into consideration when addressing future treatment approaches.

Bilateral sensory effects of unilateral passive accessory mobilization in patients with thumb carpometacarpal osteoarthritis

OBJECTIVE

The purpose of this study was to investigate changes in pressure sensitivity and pinch grip force in the nonsymptomatic side in patients with thumb carpometacarpal (CMC) osteoarthritis (OA) after the application of a unilateral passive accessory mobilization to the symptomatic hand.

METHODS

Secondary analysis of data from a randomized trial with concealed allocation, blinded assessor, and intention-to-treat analysis was performed. Twenty-eight patients (72% females), with unilateral CMC OA and mean age ± SD of 82 ± 6 years, met all the inclusion criteria and agreed to participate. The experimental group received passive accessory mobilization to the CMC OA, and the control group received a nontherapeutic dose of intermittent ultrasound on the affected side for 4 sessions over 2 weeks. Outcome measures including pressure pain thresholds (PPTs) at the lateral epicondyle, thumb CMC joint, tubercle of the scaphoid bone, and the unciform apophysis of the hamate bone and tip and tripod pinch and grip strength of the contralateral/unaffected hand were assessed at baseline as well as 1 and 2 weeks after treatment by an assessor blinded to the group allocation. A repeated measures analysis of variance was used to determine changes in PPT and pinch and grip strength.

RESULTS

No important baseline differences were observed between groups. At the end of the follow-up period, the experimental group exhibited a significant increase in PPT at the CMC joint as compared with the control group 0.6 kg/cm(2) (95% confidence interval, 0.3-1.0; F3.0 = 4.89; P = .009). Although PPT changes in the experimental group were higher than the control group at the remaining sites, differences did not reach statistically significance. Similarly, tip, tripod pinch, and grip strength remained unchanged after the intervention.

CONCLUSION

This secondary analysis found that the application of a unilateral passive accessory mobilization targeted to the symptomatic CMC joint induced an increase of PPT levels 2 weeks after treatment; however, differences were small and likely of limited clinical value. No contralateral motor effects were observed. Future studies including larger sample sizes are needed to examine the effects of joint mobilization on motor and sensory effects.

The effectiveness of a manual therapy and exercise protocol in patients with thumb carpometacarpal osteoarthritis: a randomized controlled trial

STUDY DESIGN

Double-blind, randomized controlled trial.

OBJECTIVE

To examine the effectiveness of a manual therapy and exercise approach relative to a placebo intervention in individuals with carpometacarpal (CMC) joint osteoarthritis (OA).

BACKGROUND

Recent studies have reported the outcomes of exercise, joint mobilization, and neural mobilization interventions used in isolation in patients with CMC joint OA. However, it is not known if using a combination of these interventions as a multimodal approach to treatment would further improve outcomes in this patient population.

METHODS

Sixty patients, 90% female (mean ± SD age, 82 ± 6 years), with CMC joint OA were randomly assigned to receive a multimodal manual treatment approach that included joint mobilization, neural mobilization, and exercise, or a sham intervention, for 12 sessions over 4 weeks. The primary outcome measure was pain. Secondary outcome measures included pressure pain threshold over the first CMC joint, scaphoid, and hamate, as well as pinch and strength measurements. All outcome measures were collected at baseline, immediately following the intervention, and at 1 and 2 months following the end of the intervention. Mixed-model analyses of variance were used to examine the effects of the interventions on each outcome, with group as the between-subject variable and time as the within-subject variable.

RESULTS

The mixed-model analysis of variance revealed a group-by-time interaction (F = 47.58, P<.001) for pain intensity, with the patients receiving the multimodal intervention experiencing a greater reduction in pain compared to those receiving the placebo intervention at the end of the intervention, as well as at 1 and 2 months after the intervention (P<.001; all group differences greater than 3.0 cm, which is greater than the minimal clinically important difference of 2.0 cm). A significant group-by-time interaction (F = 3.19, P = .025) was found for pressure pain threshold over the hamate bone immediately after the intervention; however, the interaction was no longer significant at 1 and 2 months postintervention.

CONCLUSION

This clinical trial provides evidence that a combination of joint mobilization, neural mobilization, and exercise is more beneficial in treating pain than a sham intervention in patients with CMC joint OA. However, the treatment approach has limited value in improving pressure pain thresholds, as well as pinch and grip strength. Future studies should include several therapists, a measure of function, and long-term outcomes.
