Clinical Effects of Dry Needling Among Asymptomatic Individuals With Hamstring Tightness: A Randomized Controlled Trial.

STUDY DESIGN: Randomized controlled trial. OBJECTIVES: The aim of this study was to determine the effects of dry needling on hamstring extensibility and functional performance tests among asymptomatic individuals with hamstring muscle tightness. BACKGROUND: Dry needling has been shown to increase range of motion in the upper quarter and may have similar effects in the lower quarter. METHODS: 27 subjects with hamstring extensibility deficits were randomly assigned to side of treatment (dominant or nondominant) and group (blunt needling or dry needling). The first session included measurement of hamstring extensibility and performance on 4 unilateral hop tests, instruction in home hamstring stretching exercises and needling distal to the ischial tuberosity and midbellies of the medial and lateral hamstrings. A second session, 3-5 days following the first session, included outcome measures and a second needling intervention, and a third session, 4-6 weeks following the first session, included outcome measures only. A 2 × 3 × 2 ANOVA was used to statistically analyze the data. RESULTS: Hamstring extensibility showed a significant side × time interaction (P < .05). The single hop for distance, timed 6-meter hop, and the crossover hop test had a significant main effect of time (P < .05). The triple hop for distance showed a significant side × time × group interaction (P < .05). CONCLUSIONS: It does not appear dry needling results in increased extensibility beyond that of stretching alone in asymptomatic individuals. Our study findings suggest that dry needling may improve certain dimensions of functional performance, although no clear conclusion can be made. LEVEL OF EVIDENCE: Intervention, level 2b.

The utilization of dry needling and an upper extremity exercise program for individuals with cervicogenic headaches: A pilot study.

OBJECTIVE: To investigate whether a combination of dry-needling treatments and upper extremity neuromuscular reeducation exercises can significantly improve neck pain and/or headache-related disability, joint position error, cervical range of motion, and pain pressure threshold in individuals suffering from cervicogenic headache (CGH). METHODS: This study is a quasi-experimental design. Seven participants met the inclusion criteria and received dry needling to three muscles that reproduced the participant's headache symptoms and completed the Neck Disability Index (NDI), Headache Disability Inventory (HDI), Visual Analog Scale (VAS), and Numeric Pain Rating Scale (NPRS). Participants performed an exercise regimen designed to address strength and mobility of cervical and scapulothoracic musculature. RESULTS: There were significant improvements seen in cervical range of motion and neck pain-related disability (NDI) during the 4-week treatment period. CONCLUSION: Dry needling and neuromuscular re-education (NMR) exercises could be effective components of treatment for individuals suffering from CGH to reduce disability and pain.

Short-term effects of dry needling at a spinal and peripheral site on functional outcome measures, strength, and proprioception among individuals with a lateral ankle sprain.

BACKGROUND: The purpose of the study was to compare the effects of spinal and peripheral dry needling with peripheral dry needling alone, in addition to a strength and proprioception home exercise program, on pain, balance, strength, proprioception, and functional limitations among individuals with a history of a lateral ankle sprain. METHODS: The study design is a single-blinded, repeated measures randomized clinical trial. Thirty-four participants, aged 18-50, with a history of a lateral ankle sprain within the last twelve months were randomly assigned into a peripheral dry needling (PDN) group or a spinal and peripheral dry needling (SPDN) group. Outcome measures included a pain assessment, strength testing, Modified Clinical Test of Sensory Integration and Balance, physical performance on hop tests, Cumberland Ankle Instability Tool and the Foot and Ankle Disability Index assessed at baseline, one week, and at four to six weeks. RESULTS: The mixed model ANOVAs showed significant side by time interaction (p < 0.05) for inverter/dorsiflexion strength and significant improvements in side, time, and side by time (p < 0.05) for the CAIT. CONCLUSION: Trigger point dry needling demonstrated short-term improvements in strength of the inverters/dorsiflexors and the CAIT scores on the involved side at one week and at four to six weeks irrespective of a PDN or SPDN approach. DISCUSSION: These results suggest that improvements in strength and function can be achieved with PDN without additional needling at the corresponding spinal level.

Clinical narratives in residency education: Exploration of the learning process.

Background: Post-professional residency educational programs aim to advance the knowledge and skills of therapists in a clinical specialty area, however, little is known about the process, outcomes, or effectiveness of residency education. Purpose: The purpose of this study was to use narrative as a teaching and learning tool to gain insight into the progressive development of the residents' learning process. Design: Qualitative methods including a retrospective analysis of residents' narratives were used to explore the professional development and thought process of residents. Methods: Six physical therapy residents wrote reflective narratives across 4 time placements during their one-year residency. Qualitative content analysis was used to analyze the data for types of reflection across time frames and to construct themes based on meaning statements. Results: Four main themes evolved from the residents' clinical narratives: 1) developing clinical reasoning skills; 2) developing professional formation and identity; 3) moral agency; and 4) emerging characteristics of expertise Conclusions: In this study, clinical narratives served as a pedagogical tool to enhance aspects of clinical expertise. The utilization of clinical narrative may be used as one tool to help to create reflective practitioners with improved skills foundational to clinical practice.

SPINAL AND PERIPHERAL DRY NEEDLING VERSUS PERIPHERAL DRY NEEDLING ALONE AMONG INDIVIDUALS WITH A HISTORY OF LATERAL ANKLE SPRAIN: A RANDOMIZED CONTROLLED TRIAL.

BACKGROUND: In addition to established interventions, dry needling may reduce impairments leading to greater functional abilities for individuals following ankle sprain. HYPOTHESIS/PURPOSE: The purpose of this study was to compare effects of spinal and peripheral dry needling (DN) with peripheral DN alone on impairments and functional performance among individuals with a history of lateral ankle sprain. STUDY DESIGN: Randomized controlled trial. METHODS: Twenty individuals with a history of lateral ankle sprain (18 bilateral, 2 unilateral) participated in this study (4 males, 16 females; mean age 28.9 + /- 9.2 years). During the first of two sessions, participants completed the Foot and Ankle Disability Index (FADI) and the Cumberland Ankle Instability Tool (CAIT) and their strength, unilateral balance, and unilateral hop test performance was assessed. Participants were randomly assigned to a spinal and peripheral DN group (SPDN), or a peripheral only DN group (PDN). Participants in the SPDN site group received DN to bilateral L5 multifidi and fibularis longus and brevis muscles on the involved lower extremity. Participants in the PDN group received DN to the fibularis muscles alone. Participants' strength, balance and hop test performance were reassessed immediately following the intervention, and at follow-up 6-7 days later, all outcome measures were reassessed. Three-way mixed model ANOVAs and Mann-Whitney U tests assessed between group differences for outcome variables with normal distributions and non-normal distributions, respectively. RESULTS: ANOVAs showed significant group by time interaction (p<0.05) for invertor strength, significant side by group and time by group interactions (p<0.05) for plantarflexor-evertor strength, no significant findings for dorsiflexor-invertor strength, significant side by time interaction (p<0.05) for unilateral balance, significant main effect of time (p<0.05) for triple hop for distance test, and significant main effect of side (p<0.05) for the CAIT. Mann-Whitney U tests showed no significance (p>0.05) for the side hop test or FADI. CONCLUSION: The results suggest that DN of the multifidi in addition to fibularis muscles does not result in improvements in strength, unilateral balance or unilateral hop test performance, compared to DN the fibularis muscles alone among individuals with a history of ankle sprain.

The effect of subtalar joint position on dorsiflexion of the ankle/rearfoot versus midfoot/forefoot during gastrocnemius stretching.

BACKGROUND: Limited ankle joint dorsiflexion passive range of motion (PROM) has been associated with common chronic lower extremity conditions, and clinicians often instruct patients in stretching exercises to increase dorsiflexion. However, little is known about how subtalar joint (STJ) position affects dorsiflexion at the midfoot/forefoot versus ankle/rearfoot during gastrocnemius stretching. The purpose of this study was to determine if more dorsiflexion occurs at the ankle/rearfoot and less at the midfoot/forefoot during gastrocnemius stretching with the STJ positioned in supination versus pronation. METHODS: In this repeated measures design, 27 participants (23 females, 4 males; mean age = 31.3 years, SD = 10.7) with current or recent history of lower extremity chronic conditions and less than 10 degrees ankle dorsiflexion measured with the knee in extension on the involved side(s) performed five 30-second gastrocnemius stretching trials in pronation and supination on each side in a randomly determined sequence. A 7-camera Vicon Motion Analysis System and an AMTI force plate were used to measure midfoot/forefoot dorsiflexion, ankle/rearfoot dorsiflexion, knee extension, and normalized vertical ground reaction force. RESULTS: Two-way repeated measures ANOVA revealed a significant increase in midfoot/forefoot dorsiflexion when stretching in pronation compared to supination (P < .001). ANOVAs also demonstrated significantly more extension of the knee when stretching in supination compared to pronation (P < .001), and increased normalized vertical ground reaction force when stretching in supination compared to pronation (P = .032). With the numbers available, no significant difference in ankle/rearfoot dorsiflexion when stretching in supination compared to pronation could be detected (P > .05). CONCLUSION: Gastrocnemius stretching in pronation resulted in more dorsiflexion at the midfoot/forefoot than stretching in supination. CLINICAL RELEVANCE: Clinicians may want to consider STJ position during gastrocnemius stretching to either facilitate or limit recruitment of dorsiflexion motion at the midfoot/forefoot.

The effect of goniometric alignment on passive ankle dorsiflexion range of motion among patients following ankle arthrodesis or arthroplasty.

UNLABELLED: Goniometric measurement is a standard method used to quantify limited ankle dorsiflexion (DF). However, compensatory motion at the subtalar and midtarsal joints might also contribute to the amount of ankle DF obtained by goniometric measurements. The purpose of this study was to examine the effect of goniometric alignment on DF range of motion measurement among patients following ankle arthrodesis or arthroplasty and age- and gender-matched controls. A total of 22 participants were recruited to participate in this observational cohort study, including 7 patients following total ankle arthroplasty (2 male, 5 female; mean age = 67.5 years, standard deviation [SD] = 9.6 years), 4 patients following ankle arthrodesis (2 male, 2 female; mean age = 70.5 years, SD = 5.2 years), and 11 age- and gender-matched controls (4 male, 7 female; mean age 67.5 years, SD = 9.0 years). Two investigators measured and recorded ankle DF passive range of motion (PROM) using a randomly determined sequence of 2 alignment methods: (1) the distal aspect of the lateral calcaneus, and (2) the fifth metatarsal. One-sample t tests were performed to assess differences in ankle DF between the 2 different alignment methods. Significantly greater degrees of DF were obtained when aligning with the fifth metatarsal versus the lateral calcaneus on the patients' uninvolved sides and the randomly selected side of matched controls (P < .05) but not on the patients' operative side (P > .05). This study found that more degrees of DF PROM are measured when aligning a goniometer with the fifth metatarsal versus the calcaneus on the uninvolved side of patients and matched controls. LEVELS OF EVIDENCE: Diagnostic, Level IV.
