Physical therapy management, surgical treatment, and patient-reported outcomes measures in a prospective observational cohort of patients with neurogenic thoracic outlet syndrome

OBJECTIVE: To assess the results of physical therapy management and surgical treatment in a prospective observational cohort of patients with neurogenic thoracic outlet syndrome (NTOS) using patient-reported outcomes measures. METHODS: Of 183 new patient referrals from July 1 to December 31, 2015, 150 (82%) met the established clinical diagnostic criteria for NTOS. All patients underwent an initial 6-week physical therapy trial. Those with symptom improvement continued physical therapy, and the remainder underwent surgery (supraclavicular decompression with or without pectoralis minor tenotomy). Pretreatment factors and 7 patient-reported outcomes measures were compared between the physical therapy and surgery groups using t-tests and χ RESULTS: Of the 150 patients, 20 (13%) declined further treatment or follow-up, 40 (27%) obtained satisfactory improvement with physical therapy alone, and 90 (60%) underwent surgery. Slight differences were found between the physical therapy and surgery groups in the mean ± standard error degree of local tenderness to palpation (1.7 ± 0.1 vs 2.0 ± 0.1; P = .032), the number of positive clinical diagnostic criteria (9.0 ± 0.3 vs 10.1 ± 0.1; P = .001), Cervical-Brachial Symptom Questionnaire scores (68.0 ± 4.1 vs 78.0 ± 2.7; P = .045), and Short-Form 12-item physical quality-of-life scores (35.6 ± 1.5 vs 32.0 ± 0.8; P = .019) but not other pretreatment factors. During follow-up (median, 21.1 months for physical therapy and 12.0 months for surgery), the mean change in QuickDASH scores for physical therapy was -15.6 ± 3.0 (-29.5% ± 5.7%) compared with -29.8 ± 2.4 (-47.9% ± 3.6%) for surgery (P = .001). The patient-rated outcomes for surgery were excellent for 27%, good for 36%, fair for 26%, and poor for 11%, with a strong correlation between the percentage of decline in the QuickDASH score and patient-rated outcomes (P \u3c .0001). CONCLUSIONS: The present study has demonstrated contemporary outcomes for physical therapy and surgery in a well-studied cohort of patients with NTOS, reinforcing that surgery can be effective when physical therapy is insufficient, even with substantial pretreatment disability. Substantial symptom improvement can be expected for ∼90% of patients after surgery for NTOS, with treatment outcomes accurately reflected by changes in QuickDASH scores. Within this cohort, it was difficult to identify specific predictive factors for individuals most likely to benefit from physical therapy alone vs surgery

Development and preliminary reliability testing of an assessment of patient independence in performing a treatment program: Standardized scenarios

BACKGROUND: Physical therapists often assess patient independence through observation, however it is not known if therapists make these judgments reliably. We have developed a standardized method to assess a patient’s ability to perform his or her treatment program independently. OBJECTIVES: To develop a standardized assessment of patient independence in performance of a treatment program and examine the intra- and inter-rater reliability decisions made by two physical therapists. DESIGN: Test-retest. METHODS: An assessment of patient independence in performance was developed. Standardized patient scenarios were used to assess the intra- and inter-tester reliability of two physical therapists. Percentage of agreement (%) and kappa’s coefficient (k and k(w)) indexed rater reliability. RESULTS: Intra-rater reliability of Therapist 1 was as follows: knowledge: %=95, k=.90; performance: %=95, k(w)=.82. Intra-rater reliability of Therapist 2 was as follows: knowledge: %=85, k=.68; performance: %=94, k(w)=.80. Inter-rater reliability for knowledge was %=91 and k=.79 and for performance was %=91 and k(w)=.72. CONCLUSION: Trained therapists displayed substantial to excellent intra-rater reliability and substantial inter-rater reliability in assessing a patient’s independence in a treatment program

Supraclavicular decompression for neurogenic thoracic outlet syndrome in adolescent and adult populations

ObjectiveThis study was conducted to better define clinical results and understand factors determining responsiveness to surgical treatment for neurogenic thoracic outlet syndrome (NTOS) in adolescent and adult populations.MethodsA retrospective review was conducted for 189 patients with disabling NTOS who underwent primary supraclavicular decompression (scalenectomy, brachial plexus neurolysis and first rib resection, with or without pectoralis minor tenotomy) from April 2008 to December 2010. Clinical characteristics were compared between 35 adolescent patients (aged <21 years) and 154 adults (aged >21 years). Functional outcome measures were assessed before surgery and at 3- and 6-month follow-up using a composite NTOS Index combining the Disabilities of the Arm, Shoulder and Hand (DASH) survey, the Cervical-Brachial Symptom Questionnaire (CBSQ), and a 10-point visual analog scale (VAS) for pain.ResultsAdolescent and adult patients were not significantly different with respect to sex (overall 72.5% female), side affected (58.7% right, 60.3% dominant limb), bony anomalies (23.3%), previous injury (55.6%), coexisting pain disorders (11.1%), and positive responses to scalene muscle anesthetic blocks (95.6%). Compared with adults, adolescent patients had a significantly (P < .05) lower incidence of depression (11.4% vs 41.6%), motor vehicle injury (5.7% vs 20.1%), previous operations (11.4% vs 29.9%), preoperative use of opiate medications (17.1% vs 44.8%), and symptom duration >2 years (24.2% vs 50.0%). Mean preoperative NTOS Index (scale 0-100) was significantly lower in adolescent vs adult patients (46.5 ± 3.6 vs 58.5 ± 1.7; P = .009), and hospital length of stay was 4.4 ± 0.2 vs 4.9 ± 0.1 days (P = .03), but the rate of postoperative complications was no different (overall, 4.2%). Although both groups exhibited significant improvement in functional outcome measures at 3 and 6 months, adolescent patients had significantly lower NTOS Index (10.4 ± 3.1 vs 39.3 ± 3.3; P < .001) and use of opiate medications (11.4% vs 47.4%; P < .001) compared with adults.ConclusionsAdolescents undergoing supraclavicular decompression for NTOS had more favorable preoperative characteristics and enhanced 3-month and 6-month functional outcomes than adults. Further study is needed to delineate the age-dependent and independent factors that promote optimal surgical outcomes for NTOS
